PEDOLOGICAL INVESTIGATIONS IN FLORIDA

M.E. Collins


Pedology is the study of soil, as it exists
in the environment. The soil that is
studied could exist in an agricultural
field as well as in a football stadium.
Therefore, a pedologist gets involved in
research project that varies from
archaeology to zoology. Some of the on-
going and recently completed
pedological research projects are:

1. Soils in Florida,
2. Minimum Flow and Levels
Criteria for Florida Lakes,
3. Genesis of Carbon
Sequestration in Humid
Spodosols,
4. Soil Contamination in Storm
Water Retention Basins through
Urban Runoff,
5. Ecological Inventory of the
National Forests in Florida,
6. Soil Characterization Data for
St. Johns River Water
Management District on the
Internet
7. Pedological Investigations in the
Northern Highlands Marginal
Zone,
8. Soil-vegetation Relationship in
Big Cypress National Preserve,
9. Explorations using Ground-
Penetrating Radar.

Traditional pedologists were involved
with the state soil-mapping (soil survey)
program. Today's pedologist is multi-
disciplined working in cooperation for


example with the Army Research Lab
for national defense or the Pound Human
Identification Lab for forensic evidence.
The following is a summary of each of
these projects. Some of these research
projects are highlighted in other Soil and
Water Science Research Briefs.


1. Soils in Florida


Many of Florida's soils are unique and
as such are not identified in any other
part of the world. The Official State Soil
of Florida Myakka soil series is
located only in the peninsular of Florida.

The unique ecosystems in the state give
rise to the unique properties of the soils.
We are privileged to have this rare,
valuable resource and must protect it for
future generations.

as sinks, to reduce the greenhouse effect.

2. Minimum Flow and Levels Criteria B i
for Florida Lakes
The Florida Legislature mandated that e
water management districts establish
minimum surface water flows for rivers
and stream and minimum water levels *
for lakes and aquifers. This study was
initiated to evaluate the application of
hydric soil indicators to determine
minimum lake levels in sandhill lakes.
The indicators will also be tested to
4. Soil Contamination in Storm Water
Retention Basins through Urban
Runoff
Soils in urban environments are creating
new challenges for pedologists. Runoff
from urban impervious surfaces into
storm water basins that act as wetlands
need to be investigated to determine the
extent of hazardous contaminants. This
research is studying the heavy metal and
hydrocarbon contents in a retention
pond's soils and sediments.

determine the existing range of water
levels on sandhill lakes.

3. Genesis of Carbon Sequestration in
Humid Spodosols
The objectives of this research were to
study carbon sequestration in
Spodosols by determining the forms of
carbon in the multiple spodic horizons,









5. Ecological Inventory of the National
Forests in Florida
The USDA-Forest Service is conducting
inventories of the soils and vegetation in
every national forest. Such inventories
took place at the Ocala, Osceola, and


Apalachicola National Forests in
Florida. Over- and under-story
vegetation were identified and the soils
associated with the ecological
communities were investigated.

6. Soil Characterization Data for St.
Johns River Water Management
District on the Internet
The website was developed so that
individuals interested in learning
specifically about soils in the St. Johns
River Water Management District may
access these data. The data and
information has been updated as much as
possible. Data on over 200 pedons that
were sampled in the District are on the
website websitee:
soilpedology.ifas.ufl.edu)

7. Pedological Investigations in the
Northern Highlands Marginal Zone
A detailed inventory is being conducted
on the soil resources at the Plant
Sciences Research and Education Center
(Pine Acres) in Marion County. The


area surveyed to date includes about 400
acres.


The objectives of the study are to
inventory and document the soil
characteristics, classify and correlate the
soils with existing soil series, estimate
the seasonal high water table of the soils,
sample soils at representative locations
for characterization of physical and
chemical properties, sample the A
horizon (topsoil) and to create a soil map
of Pine Acres. The information will be
benchmark data to be used by future
researchers.

8. Soil-vegetation Relationships in Big
Cypress National Preserve
The primary objective of this study was
to obtain baseline information about
soils in selected areas at Raccoon Point,
located in the northeast part of Big


Cypress. Raccoon Point is part of a
long-term ecology study in which the










effects of prescribed burning is being
monitored and evaluated on pine forests
and associated cypress wetlands. The
Raccoon Point area is unique in that it
may contain the only sizeable area of
virgin south Florida slash pine. This is
the first pedological investigation in Big
Cypress.

9. Explorations using Ground-
Penetrating Radar.
Ground-penetrating radar (GPR) is a
geophysical tool used to investigate
shallow underground features. It is an
excellent tool to use in Florida's soil
conditions. GPR can be used to identify
soil layers, water tables, limestone, and
clay layers to name a few. This tool has
been used by archaeologists to locate
buried artifacts as well as by forensic
anthropologist to locate evidence.

The research listed was supported by the
Florida Experiment Station and grants
from St. Johns River Water Management
District, USDA-Forest Service, and
USDI-Geological Survey.


Much research with GPR is being done
to study spatial variability of subsurface
features at depths ranging from less than
a meter to more than 20 meters!
