How to Use This Soil Survey


General Soil Map

The general soil map, which is a color map, shows the survey area divided into groups of associated soils called
general soil map units. This map is useful in planning the use and management of large areas.

To find information about your area of interest, locate that area on the map, identify the name of the map unit in the
area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of
the soils in your area.


Detailed Soil Maps

The detailed soil maps can be useful in planning the use and
management of small areas.

To find information about your area
of interest, locate that area on the
Index to Map Sheets. Note the ,
number of the map sheet and turn I Wl ,3
to that sheet.

Locate your area of interest on INDEX T
the map sheet. Note the map unit
symbols that are in that area. Turn
to the Contents, which lists the
map units by symbol and name
and shows the page where each
map unit is described.

Foreword


This soil survey contains information that affects land use planning in this survey
area. It contains predictions of soil behavior for selected land uses. The survey also
highlights soil limitations, improvements needed to overcome the limitations, and the
impact of selected land uses on the environment.
This soil survey is designed for many different users. Farmers, ranchers, foresters,
and agronomists can use it to evaluate the potential of the soil and the management
needed for maximum food and fiber production. Planners, community officials,
engineers, developers, builders, and home buyers can use the survey to plan land use,
select sites for construction, and identify special practices needed to ensure proper
performance. Conservationists, teachers, students, and specialists in recreation,
wildlife management, waste disposal, and pollution control can use the survey to help
them understand, protect, and enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. The information in this report is
intended to identify soil properties that are used in making various land use or land
treatment decisions. Statements made in this report are intended to help the land
users identify and reduce the effects of soil limitations that affect various land uses.
The landowner or user is responsible for identifying and complying with existing laws
and regulations.
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are shallow to bedrock. Some are too
unstable to be used as a foundation for buildings or roads. Clayey or wet soils are
poorly suited to use as septic tank absorption fields. A high water table makes a soil
poorly suited to basements or underground installations.
These and many other soil properties that affect land use are described in this soil
survey. Broad areas of soils are shown on the general soil map. The location of each
soil is shown on the detailed soil maps. Each soil in the survey area is described.
Information on specific uses is given for each soil. Help in using this publication and
additional information are available at the local office of the Natural Resources
Conservation Service or the Cooperative Extension Service.

GLADES COUNTY is in the south-central part of
peninsular Florida (fig. 1). It is bordered on the north
by Highlands County, on the west by Charlotte
County, and on the south by Hendry County. The
eastern border is the line of flow of the Kissimmee
River and Lake Okeechobee. A large Seminole Indian
Reservation is in the county.
Glades County has a total area of 488,000 acres,
or about 763 square miles. It is a rural county and has
little of the development pressure that occurs in
neighboring counties. The population of the county is
approximately 8,000. The county seat is Moore
Haven, which is located in the southeastern part of
the county near Lake Okeechobee. Moore Haven has
a population of approximately 1,500.
The beef industry, citrus, and sugarcane are the
main contributors to the local economy. Three small
communities are in the county-Palmdale in the west
and Buckhead Ridge and Lakeport in the east along
Lake Okeechobee. In recent years, Buckhead Ridge Figure 1.-Location of Glades County in Florida.
and Lakeport have rapidly developed as resort areas
for fishing.

Station in the period 1932 to 1989.
In summer, temperature varies only slightly from
day to day. The temperature is tempered by cumulus
clouds and rain showers during the late afternoon.
The average daily maximum temperature is about 92
degrees, and the average daily minimum temperature
is about 68 degrees. The highest recorded
temperature, which occurred during May 1953, is 103
degrees.
In winter, temperature can vary considerably
because of dry, cold air from the north. It is not
uncommon for the temperature to fall from a daytime
high in the 70's to a nighttime low in the 30's because
of a passing cold front. The coldest temperature
usually occurs the second night after a front passes.
In winter, the mean daily maximum temperature is
75 degrees and the mean daily minimum temperature
is 48 degrees. The lowest recorded temperature,
which occurred during January 1982, is 13 degrees.
Freezing temperatures can be expected several times
from mid-November to the end of March, mostly in
late December and in January. They usually occur just
before sunrise. Very rarely does the temperature not
get above 32 degrees during the day. Frost can
severely damage vegetables, new growth on citrus
trees, and improved pasture grasses, especially in the
lower areas of the county.
Rainfall is seasonally distributed. Nearly 60 percent
of the average annual precipitation falls from June
through September. Most of the rainfall in summer
comes as thundershowers of short duration during the
afternoon and early evening. Lightning activity can be
intense in these storms, and sometimes 2 or 3 inches
of rain falls in 1 to 2 hours.
Rains that last all day are rare in summer. When
such rains occur, they are usually associated with a
tropical storm. Rainfall in winter and spring is
generally less intense than the summer
thundershowers but may last 24 hours or more.
Nearly all of the precipitation in Glades County falls
as rain. Hail falls occasionally late in the spring and
early in the summer, but the hailstones generally are
small and cause little damage. Snow is very rare.
Tropical storms can occur at any time from June
through November but are most common in August
and September. These storms can produce high
winds and very heavy rainfall. They can cause
considerable damage and can cause flooding in low-
lying areas.
Periods of dry weather can occur during any
season but are most common in winter and spring.
Dry periods are more damaging in April and May than


in other months because of the higher temperatures
and the effects these conditions have on crops and
pasture grasses. Forest fires and muck fires are more
prevalent during these times. Prescribed burning
requires special care during dry periods.
Prevailing winds generally are southerly in spring
and summer and northerly in fall and winter. Wind
speed generally ranges from 8 to 15 miles per hour
during the day and usually drops below 8 miles per
hour at night.

History

Valerie Coffey contributed information for this section.

Florida became a territory of the United States in
1821, and Escambia and St. Johns Counties were
formed. In the period 1824 to 1887, Alachua,
Hillsborough, Manatee, and Desoto Counties were
formed. In 1921, several counties were formed from
Desoto County, among them was Glades County.
Moore Haven became the county seat and remains
so today.
In the early days of the county, much of the
economy was tied to the fishing industry on Lake
Okeechobee. Daily shipments of fresh fish were made
to the coast by way of the Caloosahatchee River.
Moore Haven, which was founded in 1924 by James
A. Moore, was the center of this activity. Mr. Moore
purchased 100,000 acres in the Moore Haven area
and resold large areas through his company, the
South Florida Land Company.
Moore Haven prospered until a devastating
hurricane occurred in 1926. Large areas of Glades
County were isolated by floodwater for days. Many
small towns that were beginning to become
established, such as Citrus Center, Hall City, and
Tasmania, never recovered and were abandoned.
Many businesses shut down, banks failed, and land
payments ceased.

Hydrology

Kenneth M. Campbell, geologist, Florida Geological Survey,
helped to prepared this section.

Two regional aquifer systems are important in
Glades County: the surficial and intermediate aquifer
systems (11). The Floridan aquifer system, although
utilized in the past, contains nonpotable water. The
concentration of chloride or sulfate or both is more
than 250 milligrams per liter in the Glades County
area (3).
The surficial aquifer system consists of
undifferentiated surficial sands and shell beds,








Glades County, Florida


limestone, and marl from the Caloosahatchee/Fort
Thompson and Tamiami Formations. These
formations contain water under unconfined, or water
table, conditions. The base of the surficial aquifer
system consists of relatively impermeable beds of
regional extent in the Peace River Formation. The
thickness of the surficial aquifer system ranges from
about 20 to 100 feet.
The intermediate aquifer system consists primarily
of permeable beds in the Peace River Formation and
in the Arcadia Formation where it is not in hydraulic
communication with the Floridan aquifer system.
The permeable beds are typically interbedded with
impermeable beds, and the water is under confined
conditions. In Glades County, the intermediate aquifer
system ranges from about 90 to more than 225 feet in
thickness.

Water Quality

Water quality is highly variable in the surficial and
intermediate aquifer systems but generally is better
than that of the underlying Floridan aquifer system.
Analyses of water samples indicate that generally the
water is hard (13 to 755 milligrams per liter) and that
about one-half of the wells in the county have a
concentration of total dissolved solids of more than
500 milligrams per liter (5). Sulfate, iron, chloride, and
color are all highly variable. The concentrations of
sulfate, iron, and chloride commonly exceed
standards. The concentration of ammonia exceeds
0.5 milligrams per liter in some of the water in the
county (8).

Mineral Resources

Quartz-sand and limestone are produced in Glades
County (12). Quartz-sand is mined in the vicinity of
Ortona from beds that are tentatively assigned to the
Peace River Formation. These sands are
characteristically coarse and are mined for use in
concrete and asphalt, as fine aggregate, and as filter
bed materials. Limestone is mined from an area
adjacent to the northwest shore of Lake Okeechobee
and from an area west of Moore Haven. It is used as
base material for roads.

Farming

The soils and climate in Glades County are well
suited to a variety of agricultural crops and
enterprises. Beef, citrus, and sugarcane are the most
apparent enterprises. There is limited production of
forestry products.


Raising cattle is the major agricultural enterprise in
the county. Most of this industry consists of cow-calf
operations on pastureland and rangeland. About
58,000 head of cattle are in the county. Calves are
sold and shipped to the Midwest for finishing. About
142,725 acres of improved pasture and 280,000 acres
of native range are in the county. Many breeds of
cattle, including Hereford, Angus, Brahman, and
various crosses, are produced in the county. Improved
pasture and hay grasses in the county include
bahiagrass, pangolagrass, hermarthia, and white
clover.
Recently, citrus planting has increased significantly
in the county. Advances in water management and
irrigation have made the production of citrus practical
in areas of the poorly drained soils on flatwoods.
About 9,000 acres of citrus is in the county.
Most of the citrus is grown for the production of
juice. Early varieties of oranges and grapefruit are
sometimes packed as fresh fruit.
Sugarcane is grown in large areas of organic
soils south of Lake Okeechobee. These areas have
been extensively drained. In recent years, some
varieties of sugarcane have been developed for
mineral soils. About 37,000 acres was used for
sugarcane in 1989.
Small scale vegetable or fruit operations are
scattered throughout the county. Most of these
operations are in cleared areas of native range, and
watermelon is the most commonly grown crop. Other
crops include tomatoes, cucumbers, peppers, and
squash.

How This Survey Was Made
This survey was made to provide information about
the soils and miscellaneous areas in the survey area.
The information includes a description of the soils and
miscellaneous areas and their location and a
discussion of their suitability, limitations, and
management for specified uses. Soil scientists
observed the steepness, length, and shape of the
slopes; the general pattern of drainage; the kinds of
crops and native plants; and the kinds of bedrock.
They dug many holes to study the soil profile, which is
the sequence of natural layers, or horizons, in a soil.
The profile extends from the surface down into the
unconsolidated material in which the soil formed. The
unconsolidated material is devoid of roots and other
living organisms and has not been changed by other
biological activity.
The soils and miscellaneous areas in the survey
area are in an orderly pattern that is related to the
geology, landforms, relief, climate, and natural


11












vegetation of the area. Each kind of soil and
miscellaneous area is associated with a particular
kind of landform or with a segment of the landform. By
observing the soils and miscellaneous areas in the
survey area and relating their position to specific
segments of the landform, a soil scientist develops a
concept or model of how they were formed. Thus,
during mapping, this model enables the soil scientist
to predict with a considerable degree of accuracy the
kind of soil or miscellaneous area at a specific
location on the landscape.
Commonly, individual soils on the landscape merge
into one another as their characteristics gradually
change. To construct an accurate soil map, however,
soil scientists must determine the boundaries
between the soils. They can observe only a limited
number of soil profiles. Nevertheless, these
observations, supplemented by an understanding of
the soil-vegetation-landscape relationship, are
sufficient to verify predictions of the kinds of soil in an
area and to determine the boundaries.
Soil scientists recorded the characteristics of the
soil profiles that they studied. They noted color,
texture, size and shape of soil aggregates, kind and
amount of rock fragments, distribution of plant roots,
reaction, and other features that enable them to
identify soils. After describing the soils in the survey
area and determining their properties, the soil
scientists assigned the soils to taxonomic classes
(units). Taxonomic classes are concepts. Each
taxonomic class has a set of soil characteristics with
precisely defined limits. The classes are used as a
basis for comparison to classify soils systematically.
Soil taxonomy, the system of taxonomic classification
used in the United States, is based mainly on the kind
and character of soil properties and the arrangement
of horizons within the profile. After the soil scientists
classified and named the soils in the survey area,
they compared the individual soils with similar soils in
the same taxonomic class in other areas so that they
could confirm data and assemble additional data
based on experience and research.
While a soil survey is in progress, samples of some
of the soils in the area generally are collected for
laboratory analyses and for engineering tests. Soil


scientists interpret the data from these analyses and
tests as well as the field-observed characteristics and
the soil properties to determine the expected behavior
of the soils under different uses. Interpretations for all
of the soils are field tested through observation of the
soils in different uses and under different levels of
management. Some interpretations are modified to fit
local conditions, and some new interpretations are
developed to meet local needs. Data are assembled
from other sources, such as research information,
production records, and field experience of specialists.
For example, data on crop yields under defined levels
of management are assembled from farm records and
from field or plot experiments on the same kinds of
soil.
Predictions about soil behavior are based not only
on soil properties but also on such variables as
climate and biological activity. Soil conditions are
predictable over long periods of time, but they are not
predictable from year to year. For example, soil
scientists can predict with a fairly high degree of
accuracy that a given soil will have a high water table
within certain depths in most years, but they cannot
predict that a high water table will always be at a
specific level in the soil on a specific date.
After soil scientists located and identified the
significant natural bodies of soil in the survey area,
they drew the boundaries of these bodies on aerial
photographs and identified each as a specific map
unit. Aerial photographs show trees, buildings, fields,
roads, and rivers, all of which help in locating
boundaries accurately.
This survey area was mapped in detail. The map
units are narrowly defined. Map unit boundaries were
plotted and verified at closely spaced intervals. The
detail of mapping was selected to meet the
anticipated long-term use of the survey, and the
map units were designed to meet the needs for that
use.
The descriptions; names, and delineations of the
soils in this survey area do not fully agree with those of
the soils in adjacent survey areas. Differences are the
result of a better knowledge of soils, modifications in
series concepts, or variations in the intensity of
mapping or in the extent of the soils in the survey areas.

General Soil Map Units


The general soil map at the back of this publication
shows broad areas that have a distinctive pattern of
soils, relief, and drainage. Each map unit on the
general soil map is a unique natural landscape.
Typically, it consists of one or more major soils or
miscellaneous areas and some minor soils or
miscellaneous areas. It is named for the major soils
or miscellaneous areas. The components of one
map unit can occur in another but in a different
pattern.
The general soil map can be used to compare the
suitability of large areas for general land uses. Areas
of suitable soils can be identified on the map.
Likewise, areas where the soils are not suitable can
be identified.
Because of its small scale, the map is not suitable
for planning the management of a farm or field or for
selecting a site for a road or building or other
structure. The soils in any one map unit differ from
place to place in slope, depth, drainage, and other
characteristics that affect management.

Soils of the Flatwoods

The two general soil map units in this group consist
dominantly of nearly level, poorly drained and
moderately well drained, sandy soils that have a dark,
sandy subsoil.

1. Pomello-Immokalee

Nearly level, moderately well drained and poorly
drained, sandy soils that have an organic-stained
subsoil
This map unit is in association with major
drainageways, such as Fisheating Creek. It is in
slightly elevated areas near the drainageways.
The natural vegetation is scattered slash pine,
scrub oak, saw palmetto, and pineland threeawn.
This map unit makes up 12,115 acres, or about 21/2
percent of the county. It is 70 percent Pomello soils,
10 percent Immokalee soils, and 20 percent other
soils.
Pomello soils are moderately well drained. Typically,


the surface layer is dark gray fine sand 3 inches thick.
The subsurface layer is gray and light gray fine sand
to a depth of 55 inches. The subsoil is black fine sand
to a depth of 65 inches. The substratum is dark brown
fine sand to a depth of 80 inches or more.
Immokalee soils are poorly drained. Typically, the
surface layer is very dark gray sand about 8 inches
thick. The subsurface layer is gray and white sand to a
depth of 38 inches. The subsoil extends to a depth of
80 inches or more. The upper 10 inches of the subsoil
is black sand. Below this to a depth of 55 inches is
yellowish brown sand. The lower part of the subsoil is
brown sand.
Of minor extent in this map unit are Basinger and
Myakka soils. Basinger soils are in slightly lower
positions on the landscape than the major soils and
do not have a well developed subsoil. Myakka soils
are in landscape positions similar to those of the
major soils and have a subsoil within a depth of 30
inches.
Most areas of this map still support natural
vegetation and are used for native range.
This map unit is moderately suited to citrus and
pasture. Water control and droughtiness are the major
management concerns.

organic-stained subsoil
This map unit consists of poorly drained soils in
areas of flatwoods interspersed with wet depressions.
It is the general soil map unit of greatest extent in the
county. It is mostly in the western part of the county.
The natural vegetation is slash pine, saw palmetto,
gallberry, pineland threeawn, chalky bluestem, and
creeping bluestem.
This map unit makes up 218,188 acres, or about
45 percent of the county. It is 60 percent Immokalee
soils, 30 percent Myakka soils, and 10 percent other

Detailed Soil Map Units


The map units delineated on the detailed maps at
the back of this survey represent the soils or
miscellaneous areas in the survey area. The map unit
descriptions in this section, along with the maps, can
be used to determine the suitability and potential of a
unit for specific uses. They also can be used to plan
the management needed for those uses. More
information about each map unit is given under the
heading "Use and Management of the Soils."
A map unit delineation on a map represents an
area dominated by one or more major kinds of soil or
miscellaneous areas. A map unit is identified and
named according to the taxonomic classification of
the dominant soils or miscellaneous areas. Within a
taxonomic class there are precisely defined limits for
the properties of the soils. On the landscape,
however, the soils and miscellaneous areas are
natural phenomena, and they have the characteristic
variability of all natural phenomena. Thus, the range of
some observed properties may extend beyond the
limits defined for a taxonomic class. Areas of soils of
a single taxonomic class rarely, if ever, can be
mapped without including areas of other taxonomic
classes. Consequently, every map unit is made up of
the soils or miscellaneous areas for which it is named
and some "included" areas that belong to other
taxonomic classes.
Most included soils have properties similar to those
of the dominant soil or soils in the map unit, and thus
they do not affect use and management. These are
called noncontrasting, or similar, inclusions. They may
or may not be mentioned in the map unit description.
Other included soils and miscellaneous areas,
however, have properties and behavioral
characteristics divergent enough to affect use or to
require different management. These are called
contrasting, or dissimilar, inclusions. They generally
are in small areas and could not be mapped
separately because of the scale used. Some small
areas of strongly contrasting soils or miscellaneous
areas are identified by a special symbol on the maps.
The included areas of contrasting soils or
miscellaneous areas are mentioned in the map unit
descriptions. A few included areas may not have been
observed, and consequently they are not mentioned


in the descriptions, especially where the pattern was
so complex that it was impractical to make enough
observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of included areas in a map unit in no
way diminishes the usefulness or accuracy of the
data. The objective of mapping is not to delineate pure
taxonomic classes but rather to separate the
landscape into landforms or landform segments that
have similar use and management requirements. The
delineation of such segments on the map provides
sufficient information for the development of resource
plans, but if intensive use of small areas is planned,
onsite investigation is needed to define and locate the
soils and miscellaneous areas.
An identifying symbol precedes the map unit name
in the map unit descriptions. Each description
includes general facts about the unit and gives the
principal hazards and limitations to be considered in
planning for specific uses.
Soils that have profiles that are almost alike make
up a soil series. Except for differences in texture of
the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness,
and arrangement.
Soils of one series can differ in texture of the
surface layer, slope, stoniness, salinity, degree of
erosion, and other characteristics that affect their use.
On the basis of such differences, a soil series is
divided into soil phases. Most of the areas shown on
the detailed soil maps are phases of soil series. The
name of a soil phase commonly indicates a feature
that affects use or management. For example,
Basinger fine sand; depressional, is a phase of the
Basinger series.
Some map units are made up of two or more major
soils or miscellaneous areas. These map units are
complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or
miscellaneous areas in such an intricate pattern or in
such small areas that they cannot be shown
separately on the maps. The pattern and proportion of
the soils or miscellaneous areas are somewhat similar
in all areas. Hallandale-Pople complex is an example.
An undifferentiated group is made up of two or







Soil Survey


more soils or miscellaneous areas that could be
mapped individually but are mapped as one unit
because similar interpretations can be made for use
and management. The pattern and proportion of the
soils or miscellaneous areas in a mapped area are not
uniform. An area can be made up of only one of the
major soils or miscellaneous areas, or it can be made
up of all of them. Okeelanta and Dania soils,
depressional, is an undifferentiated group in this
survey area.
Table 2 gives the acreage and proportionate extent
of each map unit. Other tables give properties of the
soils and the limitations, capabilities, and potentials
for many uses. The Glossary defines many of the
terms used in describing the soils or miscellaneous
areas.

this map unit, the included soils make up 10 to 25
percent of the mapped area. In the remaining 15
percent, the included soils make up more than 25
percent or less than 10 percent.
The seasonal high water table is at the surface to
24 inches above the surface from June through


March. Permeability is rapid. Available water capacity
is moderate.
Most areas of this map unit still support natural
vegetation consisting of pickerelweed, maidencane,
sand cordgrass, St. Johnswort, and other water-
tolerant plants.
This map unit is not suited to cultivated crops,
the production of citrus, pasture, hay crops, or
woodland. Wetness and ponding are severe
limitations.
The potential for producing large amounts of blue
maidencane and bluejoint panicum is high. The water
level fluctuates throughout the year, creating a natural
deferment from grazing cattle. This rest period
increases forage production, but periods of high water
may reduce the grazing value of the site. This soil is in
the Fresh Water Marsh and Pond range site.
This map unit is not suited to urban uses. Ponding
and poor filtering capacity are severe limitations.
This map unit is not suited to recreational
purposes. Wetness, ponding, and sandy textures are
severe limitations.
The capability subclass is Vllw. This map unit has
not been assigned a woodland ordination symbol.


35-Arents, very steep

Arents consist of unconsolidated soil material that
has been excavated from major canals and deposited
alongside the channel. This map unit is primarily along
the edge of the Herbert Hoover dike, Harney Pond
canal, and flood control canals along the Kissimmee
River. It is also in scattered areas throughout the
county where canals were dug for water control.
Individual areas vary in size and shape but generally
are long and narrow. Areas of Arents commonly are
smoothed at the top and used as access roads.
Slopes range from 45 to 60 percent.
The texture and thickness of the layers of the
Arents are highly variable. Typically, the surface layer
is olive gray fine sand about 2 inches thick. Below this
are various layers of fine sand or loamy material from
former natural soil horizons. Colors vary from black,
gray, and olive brown to white. Some layers contain
various amounts of shell fragments.
Included in mapping are Arents that are less than 6
feet deep. These included areas are normally
associated with urban uses, and the soil material is
added to help maintain structures above a seasonal
high water table. These areas may or may not be
excessively drained, depending on the thickness of
the materials deposited and the properties of the
natural soil being covered.

36-Malabar fine sand, high

This poorly drained soil is in the slightly higher
areas in flatwoods. Individual areas are irregular in
shape. They range from 10 to more than 300 acres in
size. Slopes are smooth and slightly convex. They
range from 0 to 2 percent.
Typically, the surface layer is black fine sand about
8 inches thick. The subsurface layer is light gray fine
sand to a depth of about 35 inches. The subsoil
extends to a depth of 60 inches. In the upper part, it is
brownish yellow fine sand that has yellowish brown
mottles. In the lower part, it is grayish brown fine
sandy loam. The substratum is grayish brown fine
sand to a depth of 80 inches.
Included in mapping are small areas of Basinger,
Felda, Pineda, and Valkaria soils. Basinger and
Valkaria soils do not have a horizon that has an
increase in clay content. Felda and Pineda soils have
a horizon that has an increase in clay content at a
depth of 20 to 40 inches. Also included are soils that
have a layer of organic staining directly above the
loamy part of the subsoil. In 90 percent of the areas of
this map unit, the included soils make up 2 to 23
percent of the mapped area. In the remaining 10
percent, the included soils make up more than 23
percent or less than 2 percent.
The seasonal high water table is at a depth of 6 to
18 inches from June through September. Permeability
is rapid in the surface and subsurface layers and in
the upper layers of the subsoil. It is slow or very slow
in the lower, loamy part of the subsoil. Available water
capacity is moderate.
Most areas of this map unit are used for improved
pasture or native range. The natural vegetation


consists of slash pine and cabbage palm and an
understory of saw palmetto, creeping bluestem,
chalky bluestem, panicums, pineland threeawn, and
lopsided Indiangrass.
This map unit is poorly suited to cultivated crops.
Wetness is a limitation. A properly designed water-
control system that provides for the removal of excess
water helps to minimize the wetness. Fertilizer and
lime should be added according to the specific needs
of the crop.
This map unit is poorly suited to the production of
citrus. Wetness is a limitation. Citrus trees can be
grown if a well designed water-control system is
installed. The system should maintain the water table
at the proper depth and provide for irrigation. Trees
should be planted on bedded rows, and a cover crop
should be maintained between the rows to help
control erosion of the beds.
This map unit is suited to pasture and hay crops.
Wetness is a limitation. Water-control measures are
needed to remove excess surface water after heavy
rainfall. Pangolagrass, improved bahiagrass, and white
clover are the best adapted pasture plants. Grazing
should be controlled to prevent overgrazing of the site
and weakening of the plants.
This map unit is suited to woodland. An equipment
limitation, seedling mortality, and plant competition
are moderate limitations. Harvesting should be
planned for the drier periods of the year to minimize
the equipment limitation. Increasing the planting rate
helps to compensate for the seedling mortality. Proper
site preparation helps to minimize the plant
competition. Trees should be planted in bedded rows
to ensure highest productivity. South Florida slash
pine is the preferred tree for planting.
This map unit has moderate to high potential for
production of desirable range plants and for producing
significant amounts of creeping bluestem, panicums,
and maidencane. Management of the native range
should include the use of cross fencing, cattle rotation
to maintain plant vigor, and careful consideration of
stocking rates. This soil is in the South Florida
Flatwoods range site.
This map unit is poorly suited to urban uses.
Wetness and the slow or very slow permeability are
limitations. A properly designed drainage system can
help to minimize these limitations. Mounding with
suitable fill material to raise the filter field a sufficient
distance above the seasonal high water table
improves septic system performance and increases
the filtering capacity. Sites for small buildings without
basements should be mounded to prevent moisture
damage.
This map unit is poorly suited to recreational

inches. It is black muck in the upper 10 inches and
black sand in the lower 8 inches. The substratum is
sand and extends to a depth of 80 inches. It is dark
gray in the upper part and light brownish gray in the
lower part.
Included in mapping are small areas of Astor,
Floridana, and Okeelanta soils. Astor and Floridana
soils do not have an organic surface layer. Okeelanta
soils have an organic layer that is more than 16
inches thick. In 90 percent of the areas of this map
unit, the included soils make up 0 to 24 percent of the
mapped area.
The seasonal high water table is at the surface
to a depth of 12 inches from June through April.
Permeability is rapid. Available water capacity is
high.
Most areas of this map unit still support natural
vegetation consisting of maidencane, sawgrass,
arrowhead, cutgrass, pickerelweed, and St. Johnswort.
This map unit is not suited to cultivated crops, the
production of citrus, pasture, hay, or woodland.
Wetness and ponding are severe limitations.
This map unit has high potential for producing
significant amounts of maidencane and cutgrass. It
can provide excellent forage for cattle during the
winter months and dry periods. Marshes and swamps
are some of the most productive areas of native range
in the county. This soil is in the Fresh Water Marsh
and Pond range site.
This map unit is not suited to urban uses. Ponding
and poor filtering capacity are severe limitations.
This map unit is not suited to recreational
purposes. Wetness and ponding are severe
limitations.
The capability subclass is IIIw. This map unit has
not been assigned a woodland ordination symbol.

Use and Management of the Soils


This soil survey is an inventory and evaluation of
the soils in the survey area. It can be used to adjust
land uses to the limitations and potentials of natural
resources and the environment. Also, it can help to
prevent soil-related failures in land uses.
In preparing a soil survey, soil scientists,
conservationists, engineers, and others collect
extensive field data about the nature and behavioral
characteristics of the soils. They collect data on erosion,
droughtiness, flooding, and other factors that affect
various soil uses and management. Field experience
and collected data on soil properties and performance
are used as a basis in predicting soil behavior.
Information in this section can be used to plan the
use and management of soils for crops and pasture;
as rangeland and woodland; as sites for buildings,
sanitary facilities, highways and other transportation
systems, and parks and other recreational facilities;
and for wildlife habitat. It can be used to identify the
potentials and limitations of each soil for specific land
uses and to help prevent construction failures caused
by unfavorable soil properties.
Planners and others using soil survey information
can evaluate the effect of specific land uses on
productivity and on the environment in all or part of
the survey area. The survey can help planners to
maintain or create a land use pattern in harmony with
the natural soil.
Contractors can use this survey to locate sources
of sand and gravel, roadfill, and topsoil. They can use
it to identify areas where bedrock, wetness, or very
firm soil layers can cause difficulty in excavation.
Health officials, highway officials, engineers, and
others may also find this survey useful. The survey
can help them plan the safe disposal of wastes and
locate sites for pavements, sidewalks, campgrounds,
playgrounds, lawns, and trees and shrubs.

Pasture and Crops
Dan Rutledge, district conservationist, Natural Resources
Conservation Service, helped prepare this section.

General management needed for pasture and
crops is suggested in this section. The estimated


yields of the main crops and pasture plants are listed
for each soil, the system of land capability
classification used by the Natural Resources
Conservation Service is explained, and prime
farmland is described.
Planners of management systems for individual
fields or farms should consider the detailed
information given in the description of each soil under
the heading "Detailed Soil Map Units." Specific
information can be obtained from the local office of
the Natural Resources Conservation Service or the
Cooperative Extension Service.
About 200,000 acres in Glades County is used for
pasture and crops. Of this total, 142,000 acres is used
for pasture, more than 9,000 acres is used for citrus
crops, and 37,000 acres is used for sugarcane. The
remaining acreage is planted to specialty crops,
including tomatoes, cucumbers, watermelons, sod,
and nursery plants.


Pasture

Pasture plants that commonly are referred to as
"improved" generally are introduced species, are
adapted to the climate, and commonly provide
improved forage quality.
Warm-season perennial grasses are the dominant
introduced forage in Glades County. These grasses
produce most of their growth in the summer. Bahiagrass
is the most common grass in the county. The scarcity
of digitgrass, limpograss, and bermudagrass is
attributed to their need for more intensive management.
Annual grasses include ryegrass, which is a cool-
season forage, and sorghum-sudangrass hybrids, which
are warm-season forages. Grasses can be
supplemented with legumes to increase forage
production, palatability, and digestibility. Legumes also
fix atmospheric nitrogen, which is then supplied to the
grasses. Legumes can reduce or eliminate the need for
applications of nitrogen fertilizer. White clover is the
major cool-season legume. Warm-season legumes
include perennials, such as carpon desmodium and
phasey bean, and annuals, such as jointvetch, hairy
indigo, and alyce clover.

Soil Survey


Some introduced plants are not adapted to the
natural environment of Florida. To insure the survival
and optimum performance of these plants, the
environment must be modified to compensate for the
shortcomings of the introduced plants. Environmental
modifications include water-control measures, such as
drainage and irrigation, and soil amendments, such as
applications of fertilizer and adjustment of pH.
Rotation grazing provides adequate rest periods
during the growing season for the forage to reproduce
and replenish root reserves. These rest periods
ensure healthy, productive, nutritious forage.
A prevalence of weeds and brush indicates the
need for improved management. Other common
problems include excessive or inadequate moisture,
low fertility or pH, uncontrolled grazing, and improper
plant selection.
Pasture is used to produce forage for beef and
dairy cattle. Commercial cow-calf operations are the
major livestock enterprises in the county. They range
from less than one hundred animals to several
hundred. Large operations generally use a
combination of rangeland and improved, or
introduced, perennial plants for forage. Small
operations generally use only improved pasture
plants.
In recent years, the higher cost of fertilizer
and equipment has slowed the conversion of
rangeland to pastureland. Some ranchers, aware
of the value of native grasses, have switched from
the intensive agronomic management approach to
a more ecologically based management of native
grasses.
Pomello soils are moderately suited to bahiagrass,
improved bermudagrass, and pangolagrass. If
properly managed, hairy indigo, alsike clover, and
jointvetch can be grown in summer and fall. Improved
bermudagrass and legumes, such as sweet clover,
can be grown if adequate amounts of lime and
fertilizer are applied.
If drained, Basinger, Felda, Immokalee, Malabar,
Myakka, Oldsmar, Pineda, Smyrna, and Valkaria soils
are well suited to bahiagrass and hermarthria grass.
Subsurface irrigation increases the length of the
growing season and the total production of forage.
These soils are well suited to legumes, such as white
clover, if adequate amounts of lime and fertilizer are
added.
Very poorly drained soils are very wet during rainy
periods. Examples are Astor, Chobee, Gator, and
Okeelanta soils. In most areas of these soils, water
stands on the surface and the production of good
quality forage is not possible unless artificial drainage
is used.


The design of surface drainage and subsurface
irrigation systems varies with the kind of soil and the
forage species. For intensive production of forage, a
combination of these systems is needed. Information
regarding the drainage and irrigation needed for each
kind of soil is available at the local office of the Natural
Resources Conservation Service.
In some parts of the county, the pastures are
greatly depleted by excessive grazing. Yields can be
increased mainly by good grassland management and
by adding lime and fertilizer. Differences in the size of
yields and kinds of pasture plants are closely related
to differences in the soils. Management of pasture is
based on the relationship of soils, pasture plants,
lime, fertilizer, and moisture.
The latest information about pasture can be
obtained from the local offices of the Natural
Resources Conservation Service and the Cooperative
Extension Service.

Crops

On many of the soils in the county, extensive
drainage is required for the production of crops.
Erosion caused by water is not a serious problem
in Glades County. Erosion generally is a hazard on
sloping soils where a cover of vegetation does not
protect the surface. Erosion can reduce productivity
and result in the sedimentation of streams.
Productivity is reduced as the surface layer erodes
and more of the subsoil is incorporated into the plow
layer. Controlling erosion minimizes the pollution of
streams and improves the quality of water for
municipal uses, for recreational uses, and for fish and
wildlife.
Erosion control practices provide a protective
surface cover, help to control runoff, and increase the
rate of water infiltration. A cropping system that keeps
a plant cover on the surface for extended periods can
hold soil losses to an amount that does not reduce
the productive capacity of the soils. Including grasses
and legumes in the cropping system helps to control
erosion and improves tilth for the crops that follow in
the rotation. The legumes also increase the nitrogen
levels in the soils
Tillage practices that leave crop residue on the
surface help to control runoff and erosion. These
practices can be adapted to most soils in the
county.
Soil blowing and wind erosion are major hazards on
the sandy and organic soils in the county. Strong
winds can damage soils and tender crops in open,
unprotected areas, especially if the soils are dry and
are not protected by a plant cover or crop residue.


44







Glades County, Florida


About three-fourths of the cropland in the county is
subject to soil blowing and wind erosion. Keeping a
plant cover or mulch on the surface helps to control
these hazards.
Wind erosion reduces soil fertility by removing the
finer soil particles and organic matter from the soil;
damages or destroys crops by sandblasting; spreads
diseases, insects, and weed seeds; and creates
health hazards and cleaning problems. Control of wind
erosion maintains soil quality, protects crops, reduces
the spread of insects and disease, and improves air
quality.
Field windbreaks of adapted trees and shrubs,
such as Carolina cherry laurel, slash pine, southern
redcedar, and Japanese privet, and strips of small
grains help to control wind erosion and crop damage.
Field windbreaks and strip crops are narrow plantings
made at right angles to the prevailing wind and at
specific intervals across the field. The intervals depend
on the erodibility of the soil and the susceptibility of the
crop to damage from sandblasting.
Information regarding conservation practices,
including the design of systems to control wind
erosion, is available from the local office of the Natural
Resources Conservation Service.
Drainage is a major management concern on much
of the cropland in the county. Some soils are naturally
so wet that unless they are drained the production of
crops commonly grown in the area generally is not
practical. Examples are the poorly drained Basinger,
EauGallie, Felda, Immokalee, Malabar, Myakka,
Pineda, Smyrna, and Valkaria soils.
Most of the soils in the county have naturally low
fertility, have a sandy surface layer, and are a light
color. Felda, Malabar, and Pineda soils have a loamy
subsoil. Astor and Valkaria soils have sandy material
to a depth of 80 inches or more. Basinger, EauGallie,
Immokalee, Myakka, Pomello, and Smyrna soils
have a dark, sandy subsoil that contains organic
carbon.
Most of the soils have a surface layer that is
strongly acid or very strongly acid. Applications of
ground limestone are required to raise the pH level
sufficiently for the production of crops. The levels of
nitrogen, potassium, and available phosphorus are
naturally low in most of the soils in the county. On all
of the soils, additions of lime and fertilizer should be
based on the results of soil tests, on the needs of the
crops, and on the expected yields. The Cooperative
Extension Service can help in determining the kind
and amount of fertilizer and lime to apply.
Soil tilth is an important factor in the germination of
seeds and in the infiltration of water into the soil. Soils
that have good tilth are granular and porous.


Yields per Acre
The average yields per acre that can be expected
of the principal crops under a high level of
management are shown in table 3. In any given year,
yields may be higher or lower than those indicated in
the table because of variations in rainfall and other
climatic factors. The land capability classification of
each map unit also is shown in the table.
The yields are based mainly on the experience and
records of farmers, conservationists, and extension
agents. Available yield data from nearby counties and
results of field trials and demonstrations are also
considered.
The management needed to obtain the indicated
yields of the various crops depends on the kind of soil
and the crop. Management can include drainage,
erosion control, and protection from flooding; the
proper planting and seeding rates; suitable high-
yielding crop varieties; appropriate and timely tillage;
control of weeds, plant diseases, and harmful insects;
favorable soil reaction and optimum levels of nitrogen,
phosphorus, potassium, and trace elements for each
crop; effective use of crop residue, barnyard manure,
and green manure crops; and harvesting that ensures
the smallest possible loss.
For yields of irrigated crops, it is assumed that the
irrigation system is adapted to the soils and to the
crops grown, that good-quality irrigation water is
uniformly applied as needed, and that tillage is kept to
a minimum.
The estimated yields reflect the productive capacity
of each soil for each of the principal crops. Yields are
likely to increase as new production technology is
developed. The productivity of a given soil compared
with that of other soils, however, is not likely to
change.
Crops other than those shown in the table are
grown in the survey area, but estimated yields are not
listed because the acreage of such crops is small.
The local office of the Natural Resources
Conservation Service or of the Cooperative Extension
Service can provide information about the
management and productivity of the soils for those
crops.

Land Capability Classification
Land capability classification shows, in a general
way, the suitability of soils for most kinds of field
crops. Crops that require special management are
excluded. The soils are grouped according to their
limitations for field crops, the risk of damage if they
are used for crops, and the way they respond to
management. The criteria used in grouping the soils

do not include major and generally expensive
landforming that would change slope, depth, or other
characteristics of the soils, nor do they include
possible but unlikely major reclamation projects.
Capability classification is not a substitute for
interpretations designed to show suitability and
limitations of groups of soils for rangeland, for
woodland, and for engineering purposes.
In the capability system, soils are generally grouped
at three levels-capability class, subclass, and unit.
Only class and subclass are used in this survey.
Capability classes, the broadest groups, are
designated by numerals I through VIII. The numerals
indicate progressively greater limitations and narrower
choices for practical use. The classes are defined as
follows:
Class I soils have few limitations that restrict their
use.
Class II soils have moderate limitations that reduce
the choice of plants or that require moderate
conservation practices.
Class III soils have severe limitations that reduce
the choice of plants or that require special
conservation practices, or both.
Class IV soils have very severe limitations that
reduce the choice of plants or that require very careful
management, or both.
Class V soils are not likely to erode but have other
limitations, impractical to remove, that limit their use.
Class VI soils have severe limitations that make
them generally unsuitable for cultivation.
Class VII soils have very severe limitations that
make them unsuitable for cultivation.
Class VIII soils and miscellaneous areas have
limitations that nearly preclude their use for
commercial crop production.
Capability subclasses are soil groups within one
class. They are designated by adding a small letter, w
or s, to the class numeral, for example, llw. The letter
w shows that water in or on the soil interferes with
plant growth or cultivation (in some soils the wetness
can be partly corrected by artificial drainage) and s
shows that the soil is limited mainly because it is
shallow, drought, or stony.
Capability units are soil groups within a subclass.
The soils in a capability unit are enough alike to be
suited to the same crops and pasture plants, to
require similar management, and to have similar
productivity. Capability units are generally designated
by adding an Arabic numeral to the subclass symbol,
for example, lle-4 and Ille-6.
The capability classification of each map unit is
given in the section "Detailed Soil Map Units" and in
the yields table.


Rangeland
Sid Brantly, State range conservationist, Natural Resources
Conservation Service, helped prepare this section.

Livestock producers manage about 37,000 head of
cattle on approximately 280,000 acres of rangeland in
Glades County. This land also provides food and
cover for wildlife and filtration and storage for
freshwater.
The native vegetation on rangeland is
predominantly grasses, grass-like plants, forbs, and
shrubs that are suitable for grazing. In Glades County,
areas of rangeland include natural grasslands,
savannahs, and lightly wooded lands. Many acres of
this rangeland have been farmed and are returning to
native vegetation. Much of this area has been invaded
by brush. A good management plan for rangeland
includes proper grazing use, a planned grazing system,
weed and brush control, and deferred grazing.
Proper grazing use requires manipulating the
length and intensity of grazing so that a maximum of
50 percent of the current year's growth of desirable
plants is removed each year. This is best
accomplished by implementing a planned grazing
system that allows for deferment periods of at least
two months during the growing season.
Weed and brush control can bring brush and weed
cover and distribution back to a level that
approximates the natural conditions. Mechanical
treatment, chemical treatment, and prescribed
burning can be used individually or in combination.
Deferred grazing that includes completely resting a
site from all livestock use improves the condition and
vigor of range plants. Normally, a deferment of at least
30 days should follow prescribed burning and a
deferment of 90 days should follow mechanical
treatment.
A range site is a distinctive kind of rangeland that
produces a characteristic natural plant community that
differs from natural plant communities on other range
sites in kind, amount, and proportion of range plants.
The relationship between soils and vegetation was
established during this survey; thus, range sites
generally can be determined directly from the soil
map. Soil properties that affect the moisture supply
and plant nutrients have the greatest influence on the
productivity of range plants.
Range condition is a measure of the present plant
community in relation to its potential. Four classes are
used to measure range condition. They are:

Excellent condition-Sites that produce more
than 75 percent of their potential


46







Glades County, Florida


Good condition-Sites that produce 51 to 75
percent of their potential
Fair condition-Sites that produce 26 to 50
percent of their potential
Poor condition-Sites that produce less than 26
percent of their potential

The productivity of a site is closely related to the
natural drainage of the soil. The wettest soils, such as
those in marshes, generally produce the greatest
amounts of vegetation. Deep, drought, sandy soils
generally produce the least amount.
In the following paragraphs, the range sites that are
most important for wildlife and livestock in Glades
County are described.
The South Florida Flatwoods range site is in nearly
level areas. It consists of scattered to numerous pine
trees and scattered saw palmetto, gallberry, and other
woody plants. It produces an abundant quantity of
grasses. Creeping bluestem is the dominant grass.
Indiangrass, chalky bluestem, panicums, and pineland
threeawn also occur in significant amounts. If areas of
this range site are allowed to deteriorate because of
uncontrolled livestock grazing and annual burning, the
amount of saw palmetto and pineland threeawn
increases significantly and the amount of bluestems,
Indiangrass, and panicums decreases.
The Slough range site is generally open grassland
in nearly level areas that act as broad natural
drainage courses. The potential plant community is
dominated by blue maidencane, chalky bluestem, and
bluejoint panicum. These grasses are all readily
utilized by livestock. If overgrazing occurs for a
prolonged period, carpetgrass and sedges replace the
better grasses.
The Freshwater Marsh and Pond range site is open
grassland marshes and ponds. It has potential for
producing significant amounts of maidencane. The
water level fluctuates throughout the year, and during
periods of high water levels a natural deferment from
livestock grazing occurs. This site is a preferred
grazing area for cattle. Prolonged overgrazing causes
deterioration of the site. The amount of pickerelweed,
sawgrass, willows, and primroses increases if
overgrazing continues.
The Sand Pine Scrub range site is on nearly level
to gently sloping uplands. It has limited potential for
producing native forage plants. It supports a relatively
dense woody understory. Livestock do not use this
site if other range sites are available. The principal
forage plants are lopsided Indiangrass, bluestems,
and low panicums.
The Cabbage Palm Flatwoods range site is in
nearly level areas. It is characterized by cabbage palm


trees scattered throughout the landscape. If areas of
this site are in excellent condition, they are preferred
livestock grazing areas and produce a large quantity
of high quality forage plants. Creeping bluestem,
chalky bluestem, and several species of panicum are
the dominant forage grasses. The amount of pineland
threeawn and saw palmetto increases if the condition
of the range site deteriorates.
The Wetland Hardwood Hammocks range site is
forested, nearly level, and somewhat poorly drained or
poorly drained. Laurel oak, live oak, water oak, red
maple, and cypress dominate the overstory, and
switchgrass, maidencane, perennial blue maidencane,
and chalky bluestem are important forage plants in
the understory. Areas of this site commonly are not
very productive because of the canopy. Common
carpetgrass is regularly found if the site degrades to
poor condition.
In Glades County, 50,000 acres of pastureland
provides habitat for a host of wildlife species, provides
filtration and storage of freshwater, and supports
about 20,000 brood cows. Bahiagrass, pangola
digitgrass, limpograss, bermudagrass, and jointvetch
are managed on much of the pastureland in the
county. A good management plan for pastureland
includes weed control, applications of fertilizer and
lime, planned grazing, and water control.
Stubble height on bahiagrass is successfully
managed at about 2 inches. Short grazing periods are
followed by 3-week rest periods. Stubble height on
pangola digitgrass is best managed at 4 to 6 inches.
Five-week rest periods are appropriate. Stubble height
on limpograsses is successfully managed at about 6
inches. Nine-week rest periods are appropriate.

Woodland Management and Productivity

Table 4 can be used by woodland owners or forest
managers in planning the use of soils for wood crops.
Only those soils suitable for wood crops are listed.
The table lists the ordination symbol for each soil.
Soils assigned the same ordination symbol require the
same general management and have about the same
potential productivity.
The first part of the ordination symbol, a number,
indicates the potential productivity of the soils for an
indicator tree species. The number indicates the
volume, in cubic meters per hectare per year, which
the indicator species can produce in a pure stand
under natural conditions. The number 1 indicates low
potential productivity; 2 or 3, moderate; 4 or 5,
moderately high; 6 to 8, high; 9 to 11, very high; and
12 to 39, extremely high. The second part of the
symbol, a letter, indicates the major kind of soil

limitation. The letter W indicates excess water in or on
the soil, and S indicates sandy texture.
In the table, slight, moderate, and severe indicate
the degree of the major soil limitations to be
considered in management.
Equipment limitation reflects the characteristics
and conditions of the soil that restrict use of the
equipment generally needed in woodland
management or harvesting. The chief characteristics
and conditions considered in the ratings are slope,
stones on the surface, rock outcrops, soil wetness,
and texture of the surface layer. A rating of slight
indicates that under normal conditions the kind of
equipment and season of use are not significantly
restricted by soil factors. Soil wetness can restrict
equipment use, but the wet period does not exceed 1
month. A rating of moderate indicates that equipment
use is moderately restricted because of one or more
soil factors. If the soil is wet, the wetness restricts
equipment use for a period of 1 to 3 months. A rating
of severe indicates that equipment use is severely
restricted either as to the kind of equipment that can
be used or the season of use. If the soil is wet, the
wetness restricts equipment use for more than 3
months.
Seedling mortality refers to the death of naturally
occurring or planted tree seedlings, as influenced by
the kinds of soil, soil wetness, or topographic
conditions. The factors used in rating the soils for
seedling mortality are texture of the surface layer,
depth to a seasonal high water table and the length of
the period when the water table is high, rock
fragments in the surface layer, effective rooting depth,
and slope aspect. A rating of slight indicates that
seedling mortality is not likely to be a problem under
normal conditions. Expected mortality is less than 25
percent. A rating of moderate indicates that some
problems from seedling mortality can be expected.
Extra precautions are advisable. Expected mortality is
25 to 50 percent. A rating of severe indicates that
seedling mortality is a serious problem. Extra
precautions are important. Replanting may be
necessary. Expected mortality is more than 50 percent.
The potential productivity of merchantable or
common trees on a soil is expressed as a site index
and as a volume number. The site index is the
average height, in feet, that dominant and codominant
trees of a given species attain in a specified number
of years. The site index applies to fully stocked, even-
aged, unmanaged stands. Commonly grown trees are
those that woodland managers generally favor in
intermediate or improvement cuttings. They are
selected on the basis of growth rate, quality, value,
and marketability.


The volume, a number, is the yield likely to be
produced by the most important trees. This number,
expressed as cubic meters per hectare per year,
indicates the amount of fiber produced in a fully
stocked, even-aged, unmanaged stand.
The first species listed under common trees for a
soil is the indicator species for that soil. It generally is
the most common species on the soil and is the one
that determines the ordination class.
Trees to plant are those that are suitable for
commercial wood production.

Recreation

The soils of the survey area are rated in table 5
according to limitations that affect their suitability for
recreation. The ratings are based on restrictive soil
features, such as wetness, slope, and texture of the
surface layer. Susceptibility to flooding is considered.
Not considered in the ratings, but important in
evaluating a site, are the location and accessibility of
the area, the size and shape of the area and its
scenic quality, vegetation, access to water, potential
water impoundment sites, and access to public sewer
lines (fig. 4). The capacity of the soil to absorb septic
tank effluent and the ability of the soil to support
vegetation are also important. Soils subject to flooding
are limited for recreational uses by the duration and
intensity of flooding and the season when flooding
occurs. In planning recreational facilities, onsite
assessment of the height, duration, intensity, and
frequency of flooding is essential.
In the table, the degree of soil limitation is
expressed as slight, moderate, or severe. Slight
means that soil properties are generally favorable and
that limitations, if any, are minor and easily overcome.
Moderate means that limitations can be overcome or
alleviated by planning, design, or special
maintenance. Severe means that soil properties are
unfavorable and that limitations can be offset only by
costly soil reclamation, special design, intensive
maintenance, limited use, or a combination of these
measures.
The information in the table can be supplemented
by other information in this survey, for example,
interpretations for septic tank absorption fields in table
8 and interpretations for dwellings without basements
and for local roads and streets in table 7.
Camp areas require site preparation, such as
shaping and leveling the tent and parking areas,
stabilizing roads and intensively used areas, and
installing sanitary facilities and utility lines. Camp
areas are subject to heavy foot traffic and some
vehicular traffic. The best soils have mild slopes and

are not wet or subject to flooding during the period of
use. The surface has few or no stones or boulders,
absorbs rainfall readily but remains firm, and is not
dusty when dry. Strong slopes and stones or boulders
can greatly increase the cost of constructing
campsites.
Picnic areas are subject to heavy foot traffic. Most
vehicular traffic is confined to access roads and
parking areas. The best soils for picnic areas are firm
when wet, are not dusty when dry, are not subject to
flooding during the period of use, and do not have
slopes or stones or boulders that increase the cost of
shaping sites or of building access roads and parking
areas.
Playgrounds require soils that can withstand
intensive foot traffic. The best soils are almost level


and are not wet or subject to flooding during the
season of use. The surface is free of stones and
boulders, is firm after rains, and is not dusty when dry.
If grading is needed, the depth of the soil over
bedrock or a hardpan should be considered.
Paths and trails for hiking and horseback riding
should require little or no cutting and filling. The best
soils are not wet, are firm after rains, are not dusty
when dry, and are not subject to flooding more than
once a year during the period of use. They have
moderate slopes and few or no stones or boulders on
the surface.
Golf fairways are subject to heavy foot traffic and
some light vehicular traffic. Cutting or filling may be
required. The best soils for use as golf fairways are
firm when wet, are not dusty when dry, and are not

subject to prolonged flooding during the period of use.
They have moderate slopes and no stones or
boulders on the surface. The suitability of the soil for
tees or greens is not considered in rating the soils.


Wildlife Habitat

John Vance, biologist, Natural Resources Conservation Service,
helped prepare this section.

Glades County is largely rural, and good wildlife
habitat is available in most areas of the county. A
large acreage remaining in native rangeland, the
wetlands along Fisheating Creek, and 44,000 acres of
wetlands inside the dike around Lake Okeechobee
provide the most valuable habitat.
The primary game species are white-tailed deer,
wild turkey, bobwhite quail, gray squirrel, mourning
dove, and feral hogs. Other wildlife species include
gray fox, skunks, otter, burrowing owls, snipe,
raccoon, opossum, bobcat, armadillo, and a variety of
songbirds, woodpeckers, wading birds, reptiles, and
amphibians. The wood duck is a year-round resident
of the wooded swamps and the Florida duck is found
in the marsh areas.
Lake Okeechobee is a prime fishing area, primarily
for largemouth bass, speckled perch (black crappie),
and catfish. The lake and the Kissimmee River,
Fisheating Creek, and the Caloosahatchee River also
provide habitat for a variety of other fishes, including
bluegill, redear, spotted and redbreast sunfish,
warmouth, chain and redfin pickerel, bowfin, and gar.
A number of endangered and threatened species
are found in Glades County, ranging from the seldom
seen red-cockaded woodpecker to more commonly
apparent species, such as caracara and wood stork.
A detailed list of species and information on range
and habitat are available at the local office of the
Natural Resources Conservation Service.
Soils affect the kind and amount of vegetation that
is available to wildlife as food and cover. They also
affect the construction of water impoundments. The
kind and abundance of wildlife depend largely on the
amount and distribution of food, cover, and water.
Wildlife habitat can be created or improved by planting
appropriate vegetation, by maintaining the existing
plant cover, or by promoting the natural establishment
of desirable plants.
In table 6, the soils in the survey area are rated
according to their potential for providing habitat for
various kinds of wildlife. This information can be used
in planning parks, wildlife refuges, nature study areas,
and other developments for wildlife; in selecting soils
that are suitable for establishing, improving, or


maintaining specific elements of wildlife habitat; and in
determining the intensity of management needed for
each element of the habitat.
The potential of the soil is rated good, fair, poor, or
very poor. A rating of good indicates that the element
or kind of habitat is easily established, improved, or
maintained. Few or no limitations affect management,
and satisfactory results can be expected. A rating of
fair indicates that the element or kind of habitat can
be established, improved, or maintained in most
places. Moderately intensive management is required
for satisfactory results. A rating of poor indicates that
limitations are severe for the designated element or
kind of habitat. Habitat can be created, improved, or
maintained in most places, but management is
difficult and must be intensive. A rating of very poor
indicates that restrictions for the element or kind of
habitat are very severe and that unsatisfactory results
can be expected. Creating, improving, or maintaining
habitat is impractical or impossible.
The elements of wildlife habitat are described in the
following paragraphs.
Grain and seed crops are domestic grains and
seed-producing herbaceous plants. Soil properties
and features that affect the growth of grain and seed
crops are depth of the root zone, texture of the
surface layer, available water capacity, wetness,
slope, surface stoniness, and flooding. Soil
temperature and soil moisture are also considerations.
Examples of grain and seed crops are corn,
soybeans, browntop, millet, wheat, and grain
sorghum.
Grasses and legumes are domestic perennial
grasses and herbaceous legumes. Soil properties and
features that affect the growth of grasses and
legumes are depth of the root zone, texture of the
surface layer, available water capacity, wetness,
surface stoniness, flooding, and slope. Soil
temperature and soil moisture are also considerations.
Examples of grasses and legumes are bahiagrass,
pangolagrass, deervetch, clover, and gesbania.
Wild herbaceous plants are native or naturally
established grasses and forbs, including weeds. Soil
properties and features that affect the growth of these
plants are depth of the root zone, texture of the
surface layer, available water capacity, wetness,
surface stoniness, and flooding. Soil temperature and
soil moisture are also considerations. Examples of
wild herbaceous plants are bluestem, goldenrod,
beggarweed, partridge pea, and bristle grasses.
Hardwood trees and woody understory produce
nuts or other fruit, buds, catkins, twigs, bark, and
foliage. Soil properties and features that affect the
growth of hardwood trees and shrubs are depth of the








Glades County, Florida


root zone, available water capacity, and wetness.
Examples of these plants are oak, palmetto,
sugarberry, redbay, wild grape, hawthorn, mulberry,
hickory, blackberry, and blueberry. Examples of fruit-
producing shrubs that are suitable for planting on soils
rated good are firethorn, persimmon, and beautyberry.
Coniferous plants furnish browse and seeds. Soil
properties and features that affect the growth of
coniferous trees, shrubs, and ground cover are depth
of the root zone, available water capacity, and wetness.
Examples of coniferous plants are pine and cypress.
Wetland plants are annual and perennial wild
herbaceous plants that grow on moist or wet sites.
Submerged or floating aquatic plants are excluded.
Soil properties and features affecting wetland plants
are texture of the surface layer, wetness, reaction,
salinity, slope, and surface stoniness. Examples of
wetland plants are smartweed, wild millet, wildrice,
cordgrass, rushes, sedges, and reeds.
Shallow water areas have an average depth of less
than 5 feet. Some are naturally wet areas. Others are
created by dams, levees, or other water-control
structures. Soil properties and features affecting
shallow water areas are depth to bedrock, wetness,
surface stoniness, slope, and permeability. Examples
of shallow water areas are marshes, waterfowl
feeding areas, and ponds.
The habitat for various kinds of wildlife is described
in the following paragraphs.
Habitat for openland wildlife consists of cropland,
pasture, meadows, and areas that are overgrown with
grasses, herbs, shrubs, and vines. These areas
produce grain and seed crops, grasses and legumes,
and wild herbaceous plants. Wildlife attracted to these
areas include bobwhite quail, dove, meadowlark, field
sparrow, cottontail, and red fox.
Habitat for woodland wildlife consists of areas of
deciduous plants or coniferous plants or both and
associated grasses, legumes, and wild herbaceous
plants. Wildlife attracted to these areas include wild
turkey, woodcock, thrushes, woodpeckers, squirrels,
gray fox, raccoon, deer, and bear.
Habitat for wetland wildlife consists of open,
marshy or swampy shallow water areas. Some of the
wildlife attracted to such areas are ducks, ibis, herons,
shore birds, otter, mink, and alligator.

Engineering

This section provides information for planning land
uses related to urban development and to water
management. Soils are rated for various uses, and the
most limiting features are identified. Ratings are given
for building site development, sanitary facilities,


construction materials, and water management. The
ratings are based on observed performance of the
soils and on the estimated data and test data in the
"Soil Properties" section.
Information in this section is intended for land use
planning, for evaluating land use alternatives, and for
planning site investigations prior to design and
construction. The information, however, has
limitations. For example, estimates and other data
generally apply only to that part of the soil within a
depth of 6 feet. Because of the map scale, small
areas of different soils may be included within the
mapped areas of a specific soil.
The information is not site specific and does not
eliminate the need for onsite investigation of the soils
or for testing and analysis by personnel experienced
in the design and construction of engineering works.
Government ordinances and regulations that
restrict certain land uses or impose specific design
criteria were not considered in preparing the
information in this section. Local ordinances and
regulations should be considered in planning, in site
selection, and in design.
Soil properties, site features, and observed
performance were considered in determining the
ratings in this section. During the fieldwork for this soil
survey, determinations were made about grain-size
distribution, liquid limit, plasticity index, soil reaction,
depth to bedrock, hardness of bedrock within 5 or 6
feet of the surface, soil wetness, depth to a seasonal
high water table, slope, likelihood of flooding, natural
soil structure aggregation, and soil density. Data were
collected about kinds of clay minerals, mineralogy of
the sand and silt fractions, and the kinds of adsorbed
cations. Estimates were made for erodibility,
permeability, corrosivity, shrink-swell potential,
available water capacity, and other behavioral
characteristics affecting engineering uses.
This information can be used to evaluate the
potential of areas for residential, commercial,
industrial, and recreational uses; make preliminary
estimates of construction conditions; evaluate
alternative routes for roads, streets, highways,
pipelines, and underground cables; evaluate
alternative sites for sanitary landfills, septic tank
absorption fields, and sewage lagoons; plan detailed
onsite investigations of soils and geology; locate
potential sources of gravel, sand, earthfill, and topsoil;
plan drainage systems, irrigation systems, ponds,
terraces, and other structures for soil and water
conservation; and predict performance of proposed
small structures and pavements by comparing the
performance of existing similar structures on the
same or similar soils.

Soil Survey


The information in the tables, along with the soil
maps, the soil descriptions, and other data provided in
this survey, can be used to make additional
interpretations.
Some of the terms used in this soil survey have a
special meaning in soil science and are defined in the
Glossary.
Building Site Development
Table 7 shows the degree and kind of soil
limitations that affect shallow excavations, dwellings
without basements, small commercial buildings, local
roads and streets, and lawns and landscaping. The
limitations are considered slight if soil properties and
site features are generally favorable for the indicated
use and limitations, if any, are minor and easily
overcome; moderate if soil properties or site features
are somewhat restrictive for the indicated use and
special planning, design, or maintenance is needed to
overcome or minimize the limitations; and severe if
soil properties or site features are so unfavorable that
special design, soil reclamation, and possibly
increased maintenance are required. Special
feasibility studies may be required where the soil
limitations are severe.
Shallow excavations are trenches or holes dug to a
maximum depth of 5 or 6 feet for basements, graves,
utility lines, open ditches, and other purposes. The
ratings are based on soil properties, site features, and
observed performance of the soils. The ease of
digging, filling, and compacting is affected by the
depth to bedrock, a cemented pan, or a very firm
dense layer; stone content; soil texture; and slope.
The time of the year that excavations can be made is
affected by the depth to a seasonal high water table
and the susceptibility of the soil to flooding. The
resistance of the excavation walls or banks to
sloughing or caving is affected by soil texture and
depth to the water table.
Dwellings and small commercial buildings are
structures built on shallow foundations on undisturbed
soil. The load limit is the same as that for single-family
dwellings no higher than three stories. Ratings are
made for small commercial buildings without
basements and for dwellings without basements. The
ratings are based on soil properties, site features, and
observed performance of the soils. A high water table,
flooding, shrinking and swelling, and organic layers
can cause the movement of footings. A high water
table, depth to bedrock or to a cemented pan, large
stones, slope, and flooding affect the ease of
excavation and construction. Landscaping and grading
that require cuts and fills of more than 5 or 6 feet are
not considered.


Local roads and streets have an all-weather
surface and carry automobile and light truck traffic all
year. They have a subgrade of cut or fill soil material;
a base of gravel, crushed rock, or stabilized soil
material; and a flexible or rigid surface. Cuts and fills
are generally limited to less than 6 feet. The ratings
are based on soil properties, site features, and
observed performance of the soils. Depth to bedrock
or to a cemented pan, a high water table, flooding,
large stones, and slope affect the ease of excavating
and grading. Soil strength (as inferred from the
engineering classification of the soil), shrink-swell
potential, frost action potential, and depth to a high
water table affect the traffic-supporting capacity.
Lawns and landscaping require soils on which turf
and ornamental trees and shrubs can be established
and maintained. The ratings are based on soil
properties, site features, and observed performance
of the soils. Soil reaction, a high water table, depth to
bedrock or to a cemented pan, the available water
capacity in the upper 40 inches, and the content of
salts, sodium, and sulfidic materials affect plant
growth. Flooding, wetness, slope, stoniness, and the
amount of sand, clay, or organic matter in the surface
layer affect trafficability after vegetation is established.
Sanitary Facilities
Table 8 shows the degree and kind of soil
limitations that affect septic tank absorption fields,
sewage lagoons, and sanitary landfills. The limitations
are considered slight if soil properties and site
features are generally favorable for the indicated use
and limitations, if any, are minor and easily overcome;
moderate if soil properties or site features are
moderately favorable for the indicated use and special
planning, design, or maintenance is needed to
overcome or minimize the limitations; and severe if
one or more soil properties or site features are
unfavorable for the use and overcoming the
unfavorable properties requires special design, extra
maintenance, or alteration.
The table also shows the suitability of the soils for
use as daily cover for landfill. A rating of good
indicates that soil properties and site features are
favorable for the use and good performance and low
maintenance can be expected; fair indicates that soil
properties and site features are moderately favorable
for the use and one or more soil properties or site
features make the soil less desirable than the soils
rated good; and poor indicates that one or more soil
properties or site features are unfavorable for the use
and overcoming the unfavorable properties requires
special design, extra maintenance, or costly
alteration.

Septic tank absorption fields are areas in which
effluent from a septic tank is distributed into the soil
through subsurface tiles or perforated pipe. Only that
part of the soil between depths of 24 and 72 inches is
evaluated. The ratings are based on soil properties,
site features, and observed performance of the soils.
Permeability, a high water table, depth to bedrock or
to a cemented pan, and flooding affect absorption of
the effluent. Large stones and bedrock or a cemented
pan interfere with installation.
Unsatisfactory performance of septic tank
absorption fields, including excessively slow
absorption of effluent, surfacing of effluent, and
hillside seepage, can affect public health. Ground
water can be polluted if highly permeable sand and
gravel or fractured bedrock is less than 4 feet below
the base of the absorption field, if slope is excessive,
or if the water table is near the surface. There must be
unsaturated soil material beneath the absorption field
to filter the effluent effectively. Many local ordinances
require that this material be of a certain thickness.
Sewage lagoons are shallow ponds constructed to
hold sewage while aerobic bacteria decompose the
solid and liquid wastes. Lagoons should have a nearly
level floor surrounded by cut slopes or embankments
of compacted soil. Lagoons generally are designed to
hold the sewage within a depth of 2 to 5 feet. Nearly
impervious soil material for the lagoon floor and sides
is required to minimize seepage and contamination of
ground water.
The table gives ratings for the natural soil that
makes up the lagoon floor. The surface layer and,
generally, 1 or 2 feet of soil material below the surface
layer are excavated to provide material for the
embankments. The ratings are based on soil
properties, site features, and observed performance
of the soils. Considered in the ratings are slope,
permeability, a high water table, depth to bedrock or
to a cemented pan, flooding, large stones, and
content of organic matter.
Excessive seepage resulting from rapid
permeability in the soil or a water table that is high
enough to raise the level of sewage in the lagoon
causes a lagoon to function unsatisfactorily. Pollution
results if seepage is excessive or if floodwater
overtops the lagoon. A high content of organic matter
is detrimental to proper functioning of the lagoon
because it inhibits aerobic activity. Slope, bedrock,
and cemented pans can cause construction problems,
and large stones can hinder compaction of the lagoon
floor.
Sanitary landfills are areas where solid waste is
disposed of by burying it in soil. There are two types
of landfill-trench and area. In a trench landfill, the


waste is placed in a trench. It is spread, compacted,
and covered daily with a thin layer of soil excavated at
the site. In an area landfill, the waste is placed in
successive layers on the surface of the soil. The
waste is spread, compacted, and covered daily with a
thin layer of soil from a source away from the site.
Both types of landfill must be able to bear heavy
vehicular traffic. Both types involve a risk of ground-
water pollution. Ease of excavation and revegetation
should be considered.
The ratings in the table are based on soil
properties, site features, and observed performance
of the soils. Permeability, depth to bedrock, a high
water table, slope, and flooding affect both types of
landfill. Texture, stones and boulders, highly organic
layers, soil reaction, and content of salts and sodium
affect trench landfills. Unless otherwise stated, the
ratings apply only to that part of the soil within a depth
of about 6 feet. For deeper trenches, a limitation rated
slight or moderate may not be valid. Onsite
investigation is needed.
Daily cover for landfill is the soil material that is
used to cover compacted solid waste in an area
sanitary landfill. The soil material is obtained offsite,
transported to the landfill, and spread over the waste.
Soil texture, wetness, coarse fragments, and slope
affect the ease of removing and spreading the
material during wet and dry periods. Loamy soils that
are free of large stones or excess gravel are the best
cover for a landfill. Clayey soils are sticky or cloddy
and are difficult to spread; sandy soils are subject to
wind erosion.
After soil material has been removed, the soil
material remaining in the borrow area must be thick
enough over bedrock or the water table to permit
revegetation. The soil material used as the final cover
for a landfill should be suitable for plants. The surface
layer generally has the best workability, more organic
matter, and the best potential for plants. Material from
the surface layer should be stockpiled for use as the
final cover.
Construction Materials
Table 9 gives information about the soils as a
source of roadfill, sand, gravel, and topsoil. The soils
are rated good, fair, or poor as a source of roadfill and
topsoil. They are rated as a probable or improbable
source of sand and gravel. The ratings are based on
soil properties and site features that affect the
removal of the soil and its use as construction
material. Normal compaction, minor processing, and
other standard construction practices are assumed.
Each soil is evaluated to a depth of 5 or 6 feet.
Roadfill is soil material that is excavated in one


53







Soil Survey


place and used in road embankments in another
place. In this table, the soils are rated as a source of
roadfill for low embankments, generally less than 6
feet high and less exacting in design than higher
embankments.
The ratings are for the soil material below the
surface layer to a depth of 5 or 6 feet. It is assumed
that soil layers will be mixed during excavating and
spreading. Many soils have layers of contrasting
suitability within their profile. The table showing
engineering index properties provides detailed
information about each soil layer. This information can
help to determine the suitability of each layer for use
as roadfill. The performance of soil after it is stabilized
with lime or cement is not considered in the ratings.
The ratings are based on soil properties, site
features, and observed performance of the soils. The
thickness of suitable material is a major consideration.
The ease of excavation is affected by large stones, a
high water table, and slope. How well the soil
performs in place after it has been compacted and
drained is determined by its strength (as inferred from
the engineering classification of the soil) and shrink-
swell potential.
Soils rated good contain significant amounts of
sand or gravel or both. They have at least 5 feet of
suitable material, a low shrink-swell potential, few
cobbles and stones, and slopes of 15 percent or less.
Depth to the water table is more than 3 feet. Soils
rated fair are more than 35 percent silt- and clay-sized
particles and have a plasticity index of less than 10.
They have a moderate shrink-swell potential, slopes
of 15 to 25 percent, or many stones. Depth to the
water table is 1 to 3 feet. Soils rated poor have a
plasticity index of more than 10, a high shrink-swell
potential, many stones, or slopes of more than 25
percent. They are wet and have a water table at a
depth of less than 1 foot. They may have layers of
suitable material, but the material is less than 3 feet
thick.
Sand and gravel are natural aggregates suitable for
commercial use with a minimum of processing. They
are used in many kinds of construction. Specifications
for each use vary widely. In the table, only the
probability of finding material in suitable quantity is
evaluated. The suitability of the material for specific
purposes is not evaluated, nor are factors that affect
excavation of the material.
The properties used to evaluate the soil as a
source of sand or gravel are gradation of grain sizes
(as indicated by the engineering classification of the
soil), the thickness of suitable material, and the
content of rock fragments. Kinds of rock, acidity, and
stratification are given in the soil series descriptions.


Gradation of grain sizes is given in the table on
engineering index properties.
A soil rated as a probable source has a layer of
clean sand or gravel or a layer of sand or gravel that is
up to 12 percent silty fines. This material must be at
least 3 feet thick and less than 50 percent, by weight,
large stones. All other soils are rated as an
improbable source. Coarse fragments of soft bedrock,
such as shale and siltstone, are not considered to be
sand and gravel.
Topsoil is used to cover an area so that vegetation
can be established and maintained. The upper 40
inches of a soil is evaluated for use as topsoil. Also
evaluated is the reclamation potential of the borrow
area.
Plant growth is affected by toxic material and by
such properties as soil reaction, available water
capacity, and fertility. The ease of excavating, loading,
and spreading is affected by rock fragments, slope, a
water table, soil texture, and thickness of suitable
material. Reclamation of the borrow area is affected
by slope, a water table, rock fragments, bedrock, and
toxic material.
Soils rated good have friable, loamy material to a
depth of at least 40 inches. They are free of stones
and cobbles, have little or no gravel, and have slopes
of less than 8 percent. They are low in content of
soluble salts, are naturally fertile or respond well to
fertilizer, and are not so wet that excavation is difficult.
Soils rated fair are sandy soils, loamy soils that
have a relatively high content of clay, soils that have
only 20 to 40 inches of suitable material, or soils that
have an appreciable amount of gravel, stones, or
soluble salts. The soils are not so wet that excavation
is difficult.
Soils rated poor are very sandy or clayey, have less
than 20 inches of suitable material, have a large
amount of gravel, stones, or soluble salts, or have a
seasonal high water table at or near the surface.
The surface layer of most soils is generally
preferred for topsoil because of its organic matter
content. Organic matter greatly increases the
absorption and retention of moisture and nutrients for
plant growth.
Water Management
Table 10 gives information on the soil properties
and site features that affect water management. The
degree and kind of soil limitations are given for pond
reservoir areas; embankments, dikes, and levees; and
aquifer-fed excavated ponds. The limitations are
considered slight if soil properties and site features
are generally favorable for the indicated use and
limitations, if any, are minor and are easily overcome;







Glades County, Florida


moderate if soil properties or site features are
somewhat restrictive for the indicated use and special
planning, design, or maintenance is needed to
overcome or minimize the limitations; and severe if
soil properties or site features are unfavorable for the
use. Special design, possibly increased maintenance,
or alteration are required.
This table also gives for each soil the restrictive
features that affect drainage, irrigation, and grassed
waterways.
Pond reservoir areas hold water behind a dam or
embankment. Soils best suited to this use have low
seepage potential in the upper 60 inches. The
seepage potential is determined by the permeability of
the soil and the depth to fractured bedrock or other
permeable material. Excessive slope can affect the
storage capacity of the reservoir area.
Embankments, dikes, and levees are raised
structures of soil material, generally less than 20 feet
high, constructed to impound water or to protect land
against overflow. In this table, the soils are rated as a
source of material for embankment fill. The ratings
apply to the soil material below the surface layer to a
depth of about 5 feet. It is assumed that soil layers will
be uniformly mixed and compacted during
construction.
The ratings do not indicate the ability of the natural
soil to support an embankment. Soil properties to a
depth even greater than the height of the
embankment can affect performance and safety of the
embankment. Generally, deeper onsite investigation is
needed to determine these properties.
Soil material in embankments must be resistant to
seepage, piping, and erosion and have favorable
compaction characteristics. Unfavorable features
include less than 5 feet of suitable material and a high
content of stones or boulders, organic matter, or salts
or sodium. A high water table affects the amount of
usable material. It also affects trafficability.
Aquifer-fed excavated ponds are pits or dugouts
that extend to a ground-water aquifer or to a depth
below a permanent water table. Excluded are ponds
that are fed only by surface runoff and embankment


ponds that impound water 3 feet or more above the
original surface. Excavated ponds are affected by
depth to a permanent water table, permeability of the
aquifer, and quality of the water as inferred from the
salinity of the soil. Depth to bedrock and the content
of large stones affect the ease of excavation.
Drainage is the removal of excess surface and
subsurface water from the soil. How easily and
effectively the soil is drained depends on the depth to
bedrock, to a cemented pan, or to other layers that
affect the rate of water movement; permeability; depth
to a high water table or depth of standing water if the
soil is subject to ponding; slope; susceptibility to
flooding; subsidence of organic layers; and the
potential for frost action. Excavating and grading and
the stability of ditchbanks are affected by depth to
bedrock or to a cemented pan, large stones, slope,
and the hazard of cutbanks caving. The productivity of
the soil after drainage is adversely affected by
extreme acidity or by toxic substances in the root
zone, such as salts, sodium, and sulfur. Availability of
drainage outlets is not considered in the ratings.
Irrigation is the controlled application of water to
supplement rainfall and support plant growth. The
design and management of an irrigation system are
affected by depth to the water table, the need for
drainage, flooding, available water capacity, intake
rate, permeability, erosion hazard, and slope. The
construction of a system is affected by large stones
and depth to bedrock or to a cemented pan. The
performance of a system is affected by the depth of
the root zone, the amount of salts or sodium, and soil
reaction.
Grassed waterways are natural or constructed
channels, generally broad and shallow, that conduct
surface water to outlets at a nonerosive velocity. Large
stones, wetness, slope, and depth to bedrock or to a
cemented pan affect the construction of grassed
waterways. A hazard of wind erosion, low available
water capacity, restricted rooting depth, toxic
substances such as salts and sodium, and restricted
permeability adversely affect the growth and
maintenance of the grass after construction.

Soil Properties


Data relating to soil properties are collected during
the course of the soil survey. The data and the
estimates of soil and water features, listed in tables,
are explained on the following pages.
Soil properties are determined by field examination
of the soils and by laboratory index testing of some
benchmark soils. Established standard procedures
are followed. During the survey, many shallow borings
are made and examined to identify and classify the
soils and to delineate them on the soil maps.
Estimates of soil properties are based on field
examinations, on laboratory tests of samples from the
survey area, and on laboratory tests of samples of
similar soils in nearby areas. Tests verify field
observations, verify properties that cannot be
estimated accurately by field observation, and help to
characterize key soils.
The estimates of soil properties shown in the tables
include the range of grain-size distribution and
Atterberg limits, the engineering classification, and the
physical and chemical properties of the major layers
of each soil. Pertinent soil and water features also are
given.

Engineering Index Properties

Table 11 gives estimates of the engineering
classification and of the range of index properties for
the major layers of each soil in the survey area. Most
soils have layers of contrasting properties within the
upper 5 or 6 feet.
Depth to the upper and lower boundaries of each
layer is indicated. The range in depth and information
on other properties of each layer are given for each
soil series under the heading "Soil Series and Their
Morphology."
Texture is given in the standard terms used by the
U.S. Department of Agriculture. These terms are
defined according to percentages of sand, silt, and
clay in the fraction of the soil that is less than 2
millimeters in diameter. "Loam," for example, is soil
that is 7 to 27 percent clay, 28 to 50 percent silt, and
less than 52 percent sand. If the content of particles
coarser than sand is as much as about 15 percent, an


appropriate modifier is added, for example, "gravelly."
Textural terms are defined in the Glossary.
Classification of the soils is determined according
to the Unified soil classification system (2) and the
system adopted by the American Association of State
Highway and Transportation Officials (1).
The Unified system classifies soils according to
properties that affect their use as construction
material. Soils are classified according to grain-size
distribution of the fraction less than 3 inches in
diameter and according to plasticity index, liquid limit,
and organic matter content. Sandy and gravelly soils
are identified as GW, GP, GM, GC, SW, SP, SM, and
SC; silty and clayey soils as ML, CL, OL, MH, CH,
and OH; and highly organic soils as PT. Soils
exhibiting engineering properties of two groups can
have a dual classification, for example, CL-ML.
The AASHTO system classifies soils according to
those properties that affect roadway construction and
maintenance. In this system, the fraction of a mineral
soil that is less than 3 inches in diameter is classified
in one of seven groups from A-1 through A-7 on the
basis of grain-size distribution, liquid limit, and
plasticity index. Soils in group A-1 are coarse grained
and low in content of fines (silt and clay). At the other
extreme, soils in group A-7 are fine grained. Highly
organic soils are classified in group A-8 on the basis
of visual inspection.
Rock fragments from 3 to 10 inches in diameter are
indicated as a percentage of the total soil on a dry-
weight basis. The percentages are estimates
determined mainly by converting volume percentage
in the field to weight percentage.
Percentage (of soil particles) passing designated
sieves is the percentage of the soil fraction less than
3 inches in diameter based on an ovendry weight. The
sieves, numbers 4, 10, 40, and 200 (USA Standard
Series), have openings of 4.76, 2.00, 0.420, and
0.074 millimeters, respectively. Estimates are based
on laboratory tests of soils sampled in the survey area
and in nearby areas and on estimates made in the
field.
Liquid limit and plasticity index (Atterberg limits)
indicate the plasticity characteristics of a soil. The

Engineering Index Properties

Table 11 gives estimates of the engineering
classification and of the range of index properties for
the major layers of each soil in the survey area. Most
soils have layers of contrasting properties within the
upper 5 or 6 feet.

0.074 millimeters, respectively. Estimates are based
on laboratory tests of soils sampled in the survey area
and in nearby areas and on estimates made in the
field.
Liquid limit and plasticity index (Atterberg limits)
indicate the plasticity characteristics of a soil. The







Soil Survey


estimates are based on test data from the survey
area or from nearby areas and on field examination.
The estimates of grain-size distribution, liquid limit,
and plasticity index are generally rounded to the
nearest 5 percent. Thus, if the ranges of gradation
and Atterberg limits extend a marginal amount (1 or 2
percentage points) across classification boundaries,
the classification in the marginal zone is omitted in the
table.

Physical and Chemical Properties

Table 12 shows estimates of some characteristics
and features that affect soil behavior. These estimates
are given for the major layers of each soil in the
survey area. The estimates are based on field
observations and on test data for these and similar
soils.
Clay as a soil separate consists of mineral soil
particles that are less than 0.002 millimeter in
diameter. In this table, the estimated clay content of
each major soil layer is given as a percentage, by
weight, of the soil material that is less than 2
millimeters in diameter.
The amount and kind of clay greatly affect the
fertility and physical condition of the soil. They
determine the ability of the soil to adsorb cations and
to retain moisture. They influence shrink-swell
potential, permeability, plasticity, the ease of soil
dispersion, and other soil properties. The amount and
kind of clay in a soil also affect tillage and
earthmoving operations.
Moist bulk density is the weight of soil (ovendry)
per unit volume. Volume is measured when the soil is
at field moisture capacity, that is, the moisture content
at 1/3-bar moisture tension. Weight is determined after
drying the soil at 105 degrees C. In this table, the
estimated moist bulk density of each major soil
horizon is expressed in grams per cubic centimeter of
soil material that is less than 2 millimeters in diameter.
Bulk density data are used to compute shrink-swell
potential, available water capacity, total pore space,
and other soil properties. The moist bulk density of a
soil indicates the pore space available for water and
roots. A bulk density of more than 1.6 can restrict
water storage and root penetration. Moist bulk density
is influenced by texture, kind of clay, content of
organic matter, and soil structure.
Permeability refers to the ability of a soil to transmit
water or air. The estimates indicate the rate of
downward movement of water when the soil is
saturated. They are based on soil characteristics
observed in the field, particularly structure, porosity,
and texture. Permeability is considered in the design


of soil drainage systems and septic tank absorption
fields.
Available water capacity refers to the quantity of
water that the soil is capable of storing for use by
plants. The capacity for water storage is given in
inches of water per inch of soil for each major soil
layer. The capacity varies, depending on soil
properties that affect the retention of water and the
depth of the root zone. The most important properties
are the content of organic matter, soil texture, bulk
density, and soil structure. Available water capacity is
an important factor in the choice of plants or crops to
be grown and in the design and management of
irrigation systems. Available water capacity is not an
estimate of the quantity of water actually available to
plants at any given time.
Soil reaction is a measure of acidity or alkalinity
and is expressed as a range in pH values. The range
in pH of each major horizon is based on many field
tests. For many soils, values have been verified by
laboratory analyses. Soil reaction is important in
selecting crops and other plants, in evaluating soil
amendments for fertility and stabilization, and in
determining the risk of corrosion.
Salinity is a measure of soluble salts in the soil at
saturation. It is expressed as the electrical
conductivity of the saturation extract, in millimhos per
centimeter at 25 degrees C. Estimates are based on
field and laboratory measurements at representative
sites of nonirrigated soils. The salinity of irrigated soils
is affected by the quality of the irrigation water and by
the frequency of water application. Hence, the salinity
of soils in individual fields can differ greatly from the
value given in the table. Salinity affects the suitability
of a soil for crop production, the stability of soil if used
as construction material, and the potential of the soil
to corrode metal and concrete.
Shrink-swell potential is the potential for volume
change in a soil with a loss or gain in moisture.
Volume change occurs mainly because of the
interaction of clay minerals with water and varies with
the amount and type of clay minerals in the soil. The
size of the load on the soil and the magnitude of the
change in soil moisture content influence the amount
of swelling of soils in place. Laboratory measurements
of swelling of undisturbed clods were made for many
soils. For others, swelling was estimated on the basis
of the kind and amount of clay minerals in the soil and
on measurements of similar soils.
If the shrink-swell potential is rated moderate to
very high, shrinking and swelling can cause damage
to buildings, roads, and other structures. Special
design is often needed.
Shrink-swell potential classes are based on the







Glades County, Florida


change in length of an unconfined clod as moisture
content is increased from air-dry to field capacity. The
classes are low, a change of less than 3 percent;
moderate, 3 to 6 percent; high, more than 6 percent;
and very high, greater than 9 percent.
Erosion factor K indicates the susceptibility of a soil
to sheet and rill erosion by water. Factor K is one of
six factors used in the Universal Soil Loss Equation
(USLE) to predict the average annual rate of soil loss
by sheet and rill erosion in tons per acre per year. The
estimates are based primarily on percentage of silt,
sand, and organic matter (up to 4 percent) and on soil
structure and permeability. Values of K range from
0.02 to 0.64. Other factors being equal, the higher the
value, the more susceptible the soil is to sheet and rill
erosion by water.
Erosion factor T is an estimate of the maximum
average annual rate of soil erosion by wind or water
that can occur without affecting crop productivity over
a sustained period. The rate is in tons per acre per
year.
Wind erodibility groups are made up of soils that
have similar properties affecting their resistance to
wind erosion in cultivated areas. The groups indicate
the susceptibility of soil to wind erosion. The soils
assigned to group 1 are the most susceptible to wind
erosion, and those assigned to group 8 are the least
susceptible. The groups are as follows:
1. Coarse sands, sands, fine sands, and very fine
sands.
2. Loamy coarse sands, loamy sands, loamy fine
sands, loamy very fine sands, ash material, and
sapric soil material.
3. Coarse sandy loams, sandy loams, fine sandy
loams, and very fine sandy loams.
4L. Calcareous loams, silt loams, clay loams, and
silty clay loams.
4. Clays, silty clays, noncalcareous clay loams,
and silty clay loams that are more than 35 percent
clay.
5. Noncalcareous loams and silt loams that are
less than 20 percent clay and sandy clay loams,
sandy clays, and hemic soil material.
6. Noncalcareous loams and silt loams that are
more than 20 percent clay and noncalcareous clay
loams that are less than 35 percent clay.
7. Silts, noncalcareous silty clay loams that are
less than 35 percent clay, and fibric soil material.
8. Soils that are not subject to wind erosion
because of coarse fragments on the surface or
because of surface wetness.
Organic matter is the plant and animal residue in
the soil at various stages of decomposition. In the
table, the estimated content of organic matter is


expressed as a percentage, by weight, of the soil
material that is less than 2 millimeters in diameter.
The content of organic matter in a soil can be
maintained or increased by returning crop residue to
the soil. Organic matter affects the available water
capacity, infiltration rate, and tilth. It is a source of
nitrogen and other nutrients for crops.

Soil and Water Features

Table 13 gives estimates of various soil and water
features. The estimates are used in land use planning
that involves engineering considerations.
Hydrologic soil groups are based on estimates of
runoff potential. Soils are assigned to one of four
groups according to the rate of water infiltration when
the soils are not protected by vegetation, are
thoroughly wet, and receive precipitation from long-
duration storms.
The four hydrologic soil groups are:
Group A. Soils having a high infiltration rate (low
runoff potential) when thoroughly wet. These consist
mainly of deep, well drained to excessively drained
sands or gravelly sands. These soils have a high rate
of water transmission.
Group B. Soils having a moderate infiltration rate
when thoroughly wet. These consist chiefly of
moderately deep or deep, moderately well drained or
well drained soils that have moderately fine texture to
moderately coarse texture. These soils have a
moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when
thoroughly wet. These consist chiefly of soils having a
layer that impedes the downward movement of water
or soils of moderately fine texture or fine texture.
These soils have a slow rate of water transmission.
Group D. Soils having a very slow infiltration rate
(high runoff potential) when thoroughly wet. These
consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that
have a claypan or clay layer at or near the surface,
and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water
transmission.
Some of the soils in the table have two hydrologic
groupings, a B/D listing means that under natural
conditions this soil would be in Group D, but because
of applied management practices, such as ditching
and pumping, the soil may be assigned to Group C or
B, depending on the extent of practices applied.
Because management practices vary from site to site,
it is recommended that site specific investigations be
made to determine the proper hydrologic group.
Flooding, the temporary inundation of an area, is


59











caused by overflowing streams, by runoff from
adjacent slopes, or by tides. Water standing for short
periods after rainfall or snowmelt is not considered
flooding, and water standing in swamps and marshes
or in a closed depression is considered ponding rather
than flooding.
The table gives the frequency and duration of
flooding and the time of year when flooding is most
likely.
Frequency, duration, and probable dates of
occurrence are estimated. Frequency is expressed as
none, rare, occasional, and frequent. None means
that flooding is not probable; rare that it is unlikely but
possible under unusual weather conditions (the
chance of flooding is nearly 0 percent to 5 percent in
any year); occasional that it occurs, on the average,
once or less in 2 years (the chance of flooding is 5 to
50 percent in any year); and frequent that it occurs,
on the average, more than once in 2 years (the
chance of flooding is more than 50 percent in any
year). Common is used when the occasional and
frequent classes are grouped for certain purposes.
Duration is expressed as very brief if less than 2
days, brief if 2 to 7 days, long if 7 days to 1 month,
and very long if more than 1 month. Probable dates
are expressed in months. About two-thirds to three-
fourths of all flooding occurs during the stated
period.
The information is based on evidence in the soil
profile, namely thin strata of gravel, sand, silt, or clay
deposited by floodwater; irregular decrease in organic
matter content with increasing depth; and little or no
horizon development.
Also considered are local information about the
extent and levels of flooding and the relation of each
soil on the landscape to historic floods. Information on
the extent of flooding based on soil data is less
specific than that provided by detailed engineering
surveys that delineate flood-prone areas at specific
flood frequency levels.
High water table (seasonal) is the highest level of a
saturated zone in the soil in most years. The
estimates are based mainly on observations of the
water table at selected sites and on the evidence of a
saturated zone, namely grayish colors or mottles
(redoximorphic features) in the soil. Indicated in the
table are the depth to the seasonal high water table;
the kind of water table-that is, perched or apparent;


and the months of the year that the water table
commonly is high. A water table that is seasonally
high for less than 1 month is not indicated in the table.
An apparent water table is a thick zone of free
water in the soil. It is indicated by the level at which
water stands in an uncased borehole after adequate
time is allowed for adjustment in the surrounding soil.
Two numbers in the column showing depth to the
water table indicate the normal range in depth to a
saturated zone. Depth is given to the nearest half foot.
The first numeral in the range indicates the highest
water level. A plus sign preceding the range in depth
indicates that the water table is above the surface of
the soil. "More than 6.0" indicates that the water table
is below a depth of 6 feet or that it is within a depth of
6 feet for less than a month.
Depth to bedrock is given if bedrock is within a
depth of 5 feet. The depth is based on many soil
borings and on observations during soil mapping. The
rock is either soft or hard. If the rock is soft or
fractured, excavations can be made with trenching
machines, backhoes, or small rippers. If the rock is
hard or massive, blasting or special equipment
generally is needed for excavation.
Risk of corrosion pertains to potential soil-induced
electrochemical or chemical action that dissolves or
weakens uncoated steel or concrete. The rate of
corrosion of uncoated steel is related to such factors
as soil moisture, particle-size distribution, acidity, and
electrical conductivity of the soil. The rate of corrosion
of concrete is based mainly on the sulfate and sodium
content, texture, moisture content, and acidity of the
soil. Special site examination and design may be
needed if the combination of factors results in a
severe hazard of corrosion. The steel in installations
that intersect soil boundaries or soil layers is more
susceptible to corrosion than steel in installations that
are entirely within one kind of soil or within one soil
layer.
For uncoated steel, the risk of corrosion, expressed
as low, moderate, or high, is based on soil drainage
class, total acidity, electrical resistivity near field
capacity, and electrical conductivity of the saturation
extract.
For concrete, the risk of corrosion is also
expressed as low, moderate, or high. It is based on
soil texture, acidity, and amount of sulfates in the
saturation extract.

Classification of the Soils


The system of soil classification used by the
National Cooperative Soil Survey has six categories
(13, 15). Beginning with the broadest, these
categories are the order, suborder, great group,
subgroup, family, and series. Classification is based
on soil properties observed in the field or inferred from
those observations or from laboratory measurements.
Table 14 shows the classification of the soils in the
survey area. The categories are defined in the
following paragraphs.
ORDER. Eleven soil orders are recognized. The
differences among orders reflect the dominant soil-
forming processes and the degree of soil formation.
Each order is identified by a word ending in so/. An
example is Histisol.
SUBORDER. Each order is divided into suborders
primarily on the basis of properties that influence soil
genesis and are important to plant growth or
properties that reflect the most important variables
within the orders. The last syllable in the name of a
suborder indicates the order. An example is Saprist
(meaning the soil has more sapric soil material than
any other kind of organic soil material).
GREAT GROUP. Each suborder is divided into
great groups on the basis of close similarities in kind,
arrangement, and degree of development of
pedogenic horizons; soil moisture and temperature
regimes; type of saturation; and base status. Each
great group is identified by the name of a suborder
and by a prefix that indicates a property of the soil. An
example is Medisaprist (Med, meaning of mid latitude,
plus saprist, the suborder of the Histisols that consists
almost completely of decomposed plant remains).
SUBGROUP. Each great group has a typic
subgroup. Other subgroups are intergrades or
extragrades. The typic subgroup is the central concept
of the great group; it is not necessarily the most
extensive. Intergrades are transitions to other orders,
suborders, or great groups. Extragrades have some
properties that are not representative of the great
group but do not indicate transitions to any other
taxonomic class. Each subgroup is identified by one
or more adjectives preceding the name of the great
group. The adjective Typic identifies the subgroup that


typifies the great group. An example is Typic
Medisaprist.
FAMILY. Families are established within a subgroup
on the basis of physical and chemical properties and
other characteristics that affect management.
Generally, the properties are those of horizons below
plow depth where there is much biological activity.
Among the properties and characteristics considered
are particle size, mineral content, soil temperature
regime, soil depth, and reaction. A family name
consists of the name of a subgroup preceded by
terms that indicate soil properties. An example is euic,
hyperthermic Typic Medisaprist.
SERIES. The series consists of soils within a family
that have horizons similar in color, texture, structure,
reaction, consistence, mineral and chemical
composition, and arrangement in the profile.

Soil Series and Their Morphology

In this section, each soil series recognized in the
survey area is described. Characteristics of the soil
and the material in which it formed are identified for
each series. A pedon, a small three-dimensional area
of soil, that is typical of the series in the survey area
is described. The detailed description of each soil
horizon follows standards in the "Soil Survey Manual"
(14). Many of the technical terms used in the
descriptions are defined in "Soil Taxonomy" (13) and
in "Keys to Soil Taxonomy" (15). Unless otherwise
indicated, colors in the descriptions are for moist soil.
Following the pedon description is the range of
important characteristics of the soils in the series.
The map units of each soil series are described in
the section "Detailed Soil Map Units."

Astor Series

The Astor series consists of very deep, very poorly
drained soils that formed in thick beds of sandy
marine sediments. These soils are in depressional
areas of the flatwoods and along the edges of
swamps and marshes. Under natural conditions these
soils are ponded much of the year. Slopes are less

Classification of the Soils


The system of soil classification used by the
National Cooperative Soil Survey has six categories
(13, 15). Beginning with the broadest, these
categories are the order, suborder, great group,
subgroup, family, and series. Classification is based
on soil properties observed in the field or inferred from
those observations or from laboratory measurements.
Table 14 shows the classification of the soils in the
survey area. The categories are defined in the
following paragraphs.
ORDER. Eleven soil orders are recognized. The
differences among orders reflect the dominant soil-
forming processes and the degree of soil formation.
Each order is identified by a word ending in so/. An
example is Histisol.
SUBORDER. Each order is divided into suborders
primarily on the basis of properties that influence soil
genesis and are important to plant growth or
properties that reflect the most important variables
within the orders. The last syllable in the name of a
suborder indicates the order. An example is Saprist
(meaning the soil has more sapric soil material than
any other kind of organic soil material).
GREAT GROUP. Each suborder is divided into
great groups on the basis of close similarities in kind,
arrangement, and degree of development of
pedogenic horizons; soil moisture and temperature
regimes; type of saturation; and base status. Each
great group is identified by the name of a suborder
and by a prefix that indicates a property of the soil. An
example is Medisaprist (Med, meaning of mid latitude,
plus saprist, the suborder of the Histisols that consists
almost completely of decomposed plant remains).
SUBGROUP. Each great group has a typic
subgroup. Other subgroups are intergrades or
extragrades. The typic subgroup is the central concept
of the great group; it is not necessarily the most
extensive. Intergrades are transitions to other orders,
suborders, or great groups. Extragrades have some
properties that are not representative of the great
group but do not indicate transitions to any other
taxonomic class. Each subgroup is identified by one
or more adjectives preceding the name of the great
group. The adjective Typic identifies the subgroup that


typifies the great group. An example is Typic
Medisaprist.
FAMILY. Families are established within a subgroup
on the basis of physical and chemical properties and
other characteristics that affect management.
Generally, the properties are those of horizons below

composition, and arrangement in the profile.

Pahokee Series

The Pahokee series consists of deep, very poorly
drained soils that formed in well decomposed organic
materials overlying hard limestone. These soils are in
large swamps and marshes south of Lake Okeechobee
and in small depressional areas throughout the county.
Slopes are 0 to 1 percent. These soils are euic,
hyperthermic Lithic Medisaprists.
Pahokee soils are associated with Dania,
Lauderhill, Okeelanta, and Terra Ceia soils. Dania
soils have hard limestone at a depth of less than 20
inches. Okeelanta and Terra Ceia soils do not have
limestone within the profile. Lauderhill soils have hard
limestone within a depth of 36 inches.
Typical pedon of Pahokee muck, drained; about
1,200 feet north and 1,100 feet west of the southeast
corner of sec. 25, T. 42 S., R. 33 E.


Oap-0 to 9 inches; black (N 2/0) muck; about 6
percent fiber unrubbed, less than 1 percent
rubbed; moderate medium granular structure; very
friable; dark brown (10YR 4/3) sodium
pyrophosphate extract; pH 7.0 in 0.01M CaCI,;
abrupt smooth boundary.
Oa-9 to 48 inches; black (N 2/0) muck; about 10
percent fiber unrubbed, about 2 percent rubbed;
massive; friable; dark brown (10YR 4/3) sodium
pyrophosphate extract; pH 7.2 in 0.01 M CaCI2;
clear wavy boundary.
2R-48 to 80 inches; hard limestone.
The thickness of the organic materials ranges from
36 to 51 inches. The organic materials have pH of
more than 4.5 in 0.01M calcium chloride and pH of
6.1 to 8.4 by the Hellige-Troug method. Limestone is
at depth of 36 to 51 inches.
The Oap and Oa horizons have hue of 5YR to
10YR, value of 2 or 3, and chroma of 1 or 2; or they
are neutral in hue and have value of 2. Some pedons
have a thin strata of hemic material that is less than 2
inches thick. The content of fiber is about 5 to 20
percent unrubbed and ranges from less than 1
percent to 5 percent rubbed.
The 2R layer is hard limestone.

Pineda Series

The Pineda series consists of very deep, poorly
drained soils that formed in sandy and loamy marine
sediments. These soils are in large drainageways and
broad sloughs in areas of the flatwoods. Slopes are 0
to 1 percent. These soils are loamy, siliceous,
hyperthermic Arenic Glossaqualfs.
Pineda soils are associated with Felda, Malabar,
Pople, and Valkaria soils. Felda soils do not have a
Bw horizon. Malabar soils have an argillic horizon
below a depth of 40 inches. Pople soils have
nodules of calcium carbonate above and in the Bt
horizon. Valkaria soils do not have an argillic
horizon.
Typical pedon of Pineda fine sand; about 900 feet
north and 600 feet east of the southwest corner of
sec. 20, T. 39 S., R. 33 E.
A-0 to 4 inches; gray (10YR 5/1) fine sand; single
grained; loose; many fine and medium roots;
strongly acid; clear smooth boundary.
E-4 to 11 inches; light gray (10YR 7/2) fine sand;
single grained; loose; strongly acid; gradual wavy
boundary.
Bw-11 to 22 inches; very pale brown (10YR 7/4) fine
sand; single grained; loose; moderately acid;
gradual wavy boundary.
