This study examined the economic feasibility of producing corn, milo, soybeans, wheat and
alfalfa on reclaimed phosphatic clay lands in Polk County, Florida. Livestock and poultry feed
requirements were estimated for several geographic zones around Polk County and compared with
production estimates. These comparisons indicate a ready market for these feedstuffs. Production costs
(excluding land costs) on reclaimed phosphatic clay lands were estimated and compared with recent
market prices. Alfalfa and corn generated the largest net returns per acre, follow by milo, wheat, and

MARKET POTENTIAL FOR FEED GRAINS AND ALFALFA HAY
PRODUCED ON RECLAIMED PHOSPHATIC CLAY IN FLORIDA
As the largest domestic producer of phosphate, the state of Florida accounts for an annual
average of 75 percent of total U.S. production (McHardy, 1983). Approximately 200,000 acres of mined
land in Polk County will be left after mining activities cease about the turn of the century. More than
60 percent of this land will be in the form of clay settling areas (Wood, 1986). Phosphate companies
are required under state law to reclaim the mined lands. The main objective of this study is to explore
alternative uses for this reclaimed land in order to compensate for the loss of approximately $2.5 million
annual tax revenues currently generated by the phosphate industry (Stricker, 1987).
Preliminary research conducted by the Institute of Food and Agricultural Sciences of the
University of Florida and large-scale field trials managed by several phosphate companies indicate that
reclaimed phosphatic clay lands in central Florida have the potential to produce several important feed
grains and high quality alfalfa hay if cultural problems unique to reclaimed phosphatic clay soils can be
overcome. In field trials conducted by phosphate companies, tropical field corn has yielded about 80
bushels per acre and, in smaller test plots, University of Florida researchers have obtained yields of
approximately 100 bushels per acre. Wheat and triticale yields of 40 bushels per acre have also been
achieved. Test plot yields of milo (grain sorghum) have been very good, producing approximately 5,000
pounds per acre. These yields are indications that production of these crops on phosphatic clay lands
is technically feasible.
This study examines the economic feasibility of producing the most promising feed grains and
hay crops and estimates their market potential. Issues relevant to the marketing environment for feed
grains and alfalfa hay produced on phosphatic clay and the extent to which these crops can compete with
those shipped to Florida from other states are also addressed. In order to address the major objective
of this research, specific objectives were to estimate the total quantities of selected feed crops consumed
annually in Florida counties by major classes of livestock, examine the long-term trend of prices as well
as the seasonal price behavior for each of these feed crops, estimate the cost of producing these feed
crops on phosphatic clay lands in central Florida on a commercial scale, and assess the attitudes of feed
manufacturers and major livestock and poultry producers toward feed crops grown on phosphatic clay
lands in central Florida.
To meet the aforementioned objectives of this research, both secondary and primary data were
collected. Feed consumption for individual counties in Florida was estimated by analyzing secondary
data on livestock and poultry numbers, along with feed consumption parameters for the respective
livestock and poultry species. Data on livestock and poultry were obtained from the 1982 and 1987 U.S.
Census of Agriculture, and recent estimates by Florida Agricultural Statistics Service. Estimates of feed
consumption by species were provided by researchers in the Animal Science, Dairy Science, and Poultry
Science departments at the University of Florida. Seasonal price patterns and long-term price trends
were ascertained from weekly and monthly price data for the selected feedstuffs for the 1976 through
Primary data were augmented through a survey of licensed feed manufacturers in Florida, and
several major livestock and poultry producers with their own feed mills. A detailed questionnaire was
pretested on several firms and revised prior to full-scale implementation. Fifty firms were contacted for
personal interviews. Owners or managers of feed manufacturing plants and farms were interviewed in
person or by the telephone during August and September of 1989. A total of 30 survey questionnaires
was completed. Data obtained included composition and quantities of feedstuff purchases, geographic
sources, delivered prices, sources of price information, and predominant grades or specifications of
feedstuffs. Respondents were also queried as to the likelihood of purchasing selected feedstuffs
produced on phosphatic clay lands.
Finally, production costs for corn, milo, wheat, soybeans and alfalfa hay produced on reclaimed
phosphatic clay land in central Florida were estimated using a partial budgeting technique. The
production cost estimates were based primarily on experience gained by growing these crops on research
sites of the Polk County Mined Lands Agricultural Research/Demonstration Project. The budgets were
constructed using cost data for north Florida as a base and adjusting these data to reflect production
cost differences experienced on reclaimed phosphatic clay lands.
Production and consumption estimates of feedstuffs in Florida were made to determine the
annual production shortfall of these crops. The estimates of the quantities of feedstuffs utilized annually
in Florida were derived using both secondary and primary data. The production deficits for the various
feed crops are assumed to approximate the market potential for the respective crops. This assumption
requires that relative prices for the various feedstuffs remain constant and that current producers within
the state are at least as efficient as potential producers on reclaimed phosphatic clay lands.
Production of Selected Feedstuffs
The production of field corn and soybeans in Florida has sharply declined over the last ten years.
However, production of wheat and hay has increased. Florida's corn production in 1988 was only about
one-fifth of the production in 1979. During the same time, soybean production dropped to only a
quarter of 1979 production. Hay production increased slightly over the past decade, but wheat
production increased nearly five fold. Nevertheless, wheat production is still relatively small compared
with corn and soybeans. Further, in absolute terms, the increase in wheat production was dramatically
overshadowed by the declines in corn and soybean production. The total tonnage of these major feed
items decreased by over 70 percent from 1979 to 1988 (Table 1).

Livestock and Poultry Numbers
Secondary data also indicate a decrease in all major livestock classes except sheep, but sheep
represent an almost infinitesimal proportion of animal units statewide. Also, there was a decrease in
three-month-old or older chicken inventory, but an increase in broilers and other meat-type chickens
sold (Table 2). Secondary data for horses were not available on the county level for historical

Overall, the increases in sheep and broiler production and the declines in cattle and hogs represents
a significant reduction in the demand for most feedstuffs. Even so, comparing production data on
selected feedstuffs and livestock and poultry production in Florida for the time period 1979 to 1988
shows that the rate of decrease in supplies of major feedstuffs has been considerably greater than the
rate of decrease in livestock and poultry.
Annual consumption of feed grains and alfalfa hay in Florida were estimated using livestock and
poultry numbers from the 1987 Census of Agriculture. Consumption estimates were made for dairy and
beef cattle, horses, swine and poultry. The estimates were based upon livestock and poultry numbers
from the Census and the composition of typical feed rations provided by livestock and poultry
production specialists at the University of Florida. Feed consumption was estimated by county and
categorized into three geographical areas based upon distance from the greatest concentration of
reclaimed phosphatic clay lands in Polk County: counties within a 100-mile radius, counties within a
100- to 200-mile radius, and counties outside a 200-mile radius (Figure 1). These classifications were
made in order to identify the potential geographic markets for feed grains and hay because of the
economic importance of transportation costs. Tables 3 shows consumption estimates, production, and
the resulting estimated shortfall for corn, soybeans, alfalfa hay and Bermuda hay in Florida for each of
the aforementioned geographical areas.
Corn production in Florida supplies only 17 percent of the estimated consumption for the state.
In 1987, the statewide shortfall of corn was 32.6 million bushels, with the greatest shortfall within a 100-
mile radius from phosphatic clay lands. In this geographic zone, the shortfall of corn was over 17
million bushels; in the 100- to 200-mile zone, an additional 14 million bushel shortfall was experienced.
Thus, there is substantial market potential for corn and close substitutes such as grain sorghum relatively
close to the reclaimed phosphatic clay lands, affording a significant transportation advantage. Soybean
production and soybean meal consumption was also examined for each of the geographic regions. While
^ a 0r
the shortfall (in soybean bushel equivalents) exceeds 5.6 million bushels, it is still substantially less than
the quantity required by an economically efficient processing mill. Thus, soybean production from
reclaimed phosphatic clay lands would have to be marketed through terminal markets, be transported
directly to a soybean mill, or roasted and fed locally. Because the nearest terminal markets are in north
Florida and the nearest soybean mills are located in Georgia, soybeans produced on reclaimed lands
would be subject to substantial transportation cost disadvantages if the first two marketing alternatives
were used. However, since processed whole soybeans can be fed to dairy, beef, poultry, and swine it is
likely that soybeans produced in central Florida would be processed and fed locally.
Although the hay production in Florida provides for almost three-quarters of the estimated
consumption, virtually all of the hay shortfall in the state is within a 100-mile radius from phosphatic
clay lands. Also, it is quite likely that the shortfall is particularly acute for high quality hay such as
alfalfa. Thus, it appears that there is significant market potential for alfalfa hay on phosphatic clay
The primary data collected from firms surveyed was generally consistent with the findings derived
from secondary data. Estimates of consumption derived from survey data also indicates that poultry is
the largest consumer of feedstuffs in Florida. The survey indicated that over 42 percent of volume or
44 percent of the value of the feedstuffs is consumed by poultry. Dairy cattle consume about 26 percent
of the volume and value, followed by horses, accounting for 13 and 10 percent of the tonnage and value,
respectively. Beef cattle and swine consume about six to seven percent of all feedstuffs. Feed
consumption estimates based on secondary data show the ranking, but somewhat different percentages
for some of the major classes of livestock and poultry; part of the differences arc due to the lack of
estimates for the miscellaneous category. Despite these differences, the survey of feed manufacturers
and large farms tends to confirm the large feedstuff deficits estimated using secondary data. Corn, with
an annual consumption of over 710,000 tons (more than 25 million bushels), is the most important feed
ingredient used by the 30 Florida feed manufacturers interviewed. Other major ingredients include
soybean meal with about 252,000 tons, wheat mids with 140,000 tons, and alfalfa pellets and cubes with
41,000 tons annually. Significant quantities of alfalfa hay, milo and wheat bran

Several price series were used to provide insights as to the potential profitability of feedstuff
production on reclaimed phosphatic clay lands. Long-term trends and seasonality of price fluctuations
were analyzed using Atlanta prices because adequate data for major Florida markets were unavailable.
However, recent price series for Tampa or for Florida production regions were used whenever available.
Analysis of annual price series for corn in Atlanta and Tampa, and annual average prices received by
Florida farmers, indicates a high degree of correlation among these series ( Figure 2). Thus, it is likely
that Atlanta prices for corn and the other feed items examined provide a reasonable indication of long-
term price trends. Also, because of a lack of Florida-based data, the Atlanta price series were used to
estimate seasonal price patterns as well. More recent monthly F.O.B. prices for Tampa or Florida farm
prices were used as an indication of current price levels and were used to estimate net returns for the
crops produced on phosphatic clay lands in Polk County.
Weekly F.O.B. Atlanta prices for corn, milo, wheat, soybeans and alfalfa pellets were analyzed for
a period of 13 years, 1976 through 1988. Alfalfa pellets were used as a proxy for alfalfa hay because hay
prices were unavailable. Weekly prices (unwcighted) were aggregated into annual averages. Real prices
(adjusted for inflation) were calculated using the 1982-84 Consumer Price Index (Table 5).

Over the 13-year period, all five commodities showed significant downward trends in real prices,
with most declining by 55 to 70 percent from 1976 to 1987. Milo and alfalfa pellets show sharper price
decreases than soybeans. While real prices in 1988 for milo have dropped to less than a third (from
$8.29 per cwt. in 1976 to $2.45 per cwt. in 1988) and for alfalfa pellets to less than one-half of the 1976
levels (from $223.23 per ton in 1976 to $104.62 per ton in 1988), real prices for soybeans dropped by
about 50 percent, $12.30 per bushel in 1976 to $6.39 per bushel in 1988. Although real prices for most
of the commodities showed a slight increase in 1988 and 1989, these recent increases were attributed
to the 1988 drought On a national basis, there is little evidence to indicate that real prices for the
major feedstuffs examined will regain the levels experienced in the late 1970s and early 1980s. Over the
next few years, prices are likely to be similar to those experienced in the late 1980s, barring unforeseen
Seasonal price patterns
Weekly prices for No. 2 yellow corn (F.O.B. Atlanta) for the 1976-1988 period were aggregated
into monthly observations and analyzed to determine seasonal price patterns. Atlanta prices were
selected because it is the nearest major market for which weekly prices were available; as mentioned
previously, annual corn prices for Atlanta and Tampa were found to move together, and monthly prices
probably do so as well (Figure 2).
Seasonal prices for corn tend to rise steadily in the months following harvests in the major corn-
producing states. Thus, prices typically begin to increase in November, continuing throughout the
remaining winter and spring months, with peak prices occurring in May. As substitute feedstuffs become
plentiful, and as new crops of feed grains begin to be harvested, corn prices usually begin to drop in
June and July, reaching seasonal lows in October.
Early planting (February) of corn for grain on phosphate clay lands in Polk County is not
recommended, due to the fact that harvest coincides with the summer rainy season. A new practice,
which is currently being explored, is to grow a crop of wheat or triticale from mid-November to late
April and then plant tropical corn in June in the wheat stubble with a no-till planter and harvest it in
November. This system permits harvest of both crops in the dry season and does not require irrigation.
The harvest of tropical corn in November is when prices are about five percent below the annual
average. Adequate data were not available to evaluate the economic potential of this system.

in their harvest seasons, the seasonal price patterns for milo are similar to those of corn. Peak milo
prices in Atlanta typically occur in June and July, and seasonal lows in October and November.
Unfortunately, harvest on reclaimed phosphatic clay lands would most likely coincide with the seasonal
Seasonal prices for wheat indicate a more favorable situation for production in Polk County.
The expected harvest period on the phosphatic clay lands would be April, nearly two months prior to
harvests in major production regions of the U.S. An-April harvest would result in prices that are near
Alfalfa hay production in Polk County appears to be technically feasible during two distinct
periods, March through June and October through November. A limited data series for alfalfa hay
prices in Tampa indicates that the spring harvest would probably be sold at prices that are somewhat
below the annual average, but the fall harvest would command prices that are likely to be above the
Costs of production
The costs of production estimates for the selected feedstuffs were based primarily on data from
research plots of the Polk County Mined Lands Agricultural Research/Demonstration Project in Bartow.
Land costs have been excluded from these budgets because, at the present time, there is no good means
for establishing rents or amortized development costs for phosphatic clay lands for agricultural use. Due
to the adequate amounts of phosphate, potash and lime in phosphatic clay soil, fertilizer costs are lower.
Further, the water-holding capacity of the clay reduces or eliminates the need for irrigation. However,
machinery costs will probably be higher than state averages because the heavy, sticky clay requires more
time and energy for most cultural practices, resulting in greater wear on machinery. Thus, it seems that
the fertility and irrigation advantages are going to be offset by higher labor and machinery costs.
Recent market prices and estimated production costs were analyzed for corn, milo, wheat,
soybeans and alfalfa hay. Estimated net returns for each of these crops appear below (Table 6).
Corn.--In order to incorporate the effects of the Polk County area's transportation cost
advantage, recent Tampa F.O.B. prices were used as the anticipated market prices for corn. Because
of limited data and price volatility during the 1987-89 seasons, prices for each year are shown rather
than a mean price. Tampa F.O.B. price for 1989 for the month comprising the likely harvest period for
corn on the reclaimed phosphatic clay lands was $3.31 per bushel. At a conservative yield of 80 bushels
per acre, production costs are approximately $2.34 per bushel, resulting in estimated net returns of
$77.60 per acre. It is likely that the 1989 prices were somewhat elevated due to the 1988 drought; if
future prices revert to 1987 levels, net returns would only amount to $8 per acre.
Milo.--Milo prices were not available for the Tampa market, so Tampa F.O.B. prices for No.
2 yellow corn were adjusted to reflect the historical price differential between No. 2 yellow corn and
milo in the Atlanta market for the 1976-1988 period. On a weight-equivalent basis, the milo price is
typically about 82 percent of the corn price. Thus, the estimated market price of milo in the Tampa
market in the October-November 1989 harvest period was about $4.63 per hundredweight. At a yield
of 4,000 pounds per acre, production costs were estimated at $3.82 per hundredweight, resulting in net
returns of slightly over $32.00 per acre. However, at 1987 corn prices, milo production would result in
a net loss of nearly $12.00 per acre.
Wheat.--Local (Tampa) market prices were not available for wheat. However, published price
estimates of season average prices received by Florida farmers were available. Although most Florida
wheat production occurs in the Panhandle region and in north Florida, it is assumed that Polk County
producers could obtain similar prices because wheat grown in the central Florida would be treated as
a feed grain and utilized locally. In 1989, the average price received for wheat by Florida farmers was
$3.50 per bushel. Production costs on the Polk County phosphatic clay lands, at a yield of 40 bushels
per acre, would be approximately $2.96 per bushel, resulting in net returns per acre of $21.60. If wheat
prices drop to pre-drought 1987 levels, returns would be negative. Triticale, a wheat-rye cross, also
appears to have similar or even better potential as a feedgrain. Production research on triticale is

Sovbeans.--Dccause soybeans are neither grown in the Tampa region in commercial quantities
nor widely consumed in an unprocessed state, there is no local market and hence no local price series.
However, unprocessed soybeans can be incorporated into cattle rations, and a relatively low-cost
"roaster" used to increase their feed value to livestock. Thus, it appears that a local (south and central
Florida) market could be developed for whole soybeans. The only other market alternative would be
to haul the soybeans to the nearest north Florida terminal markets, which would add approximately
$0.75 per bushel in marketing costs.
If soybeans can be sold to local users at the 1989 state farmer price of $5.45 per bushel, the
estimated net returns per acre are $14.70, assuming a yield of 30 bushels per acre. However, if the
beans have to be transported to a north Florida buyer, a net loss of $4.60 per acre is likely.
Alfalfa hav.--Monthly price estimates for alfalfa hay (F.O.B. Tampa) were available for several
years. The weighted average price for 1989 for the anticipated harvest periods was $167.50 per ton.
When establishment costs are prorated over a three-year period and yields are conservatively estimated
at four tons per acre, production costs for alfalfa hay are just under $70.00 per ton. At these costs and
prices, the net return per acre is just under $400 per acre.
Even if market prices were to decline to the 1987 levels, net returns would approach $250 per
acre. Thus, alfalfa hay appears to be one of the most promising crops for the reclaimed lands. It
should be noted, however, that there are still many unresolved land reclamation and cultural practices
that could adversely affect the estimates of net returns.
Most of the feed mill operators expressed their interest and willingness to purchase any of the
selected feedstuffs produced on phosphatic clay lands in central Florida. However, their expressed
likelihood was subject to two main conditions: quality, and price competitiveness of the feedstuffs
produced on phosphatic clay lands with those shipped to Florida from other states. Almost all of the
feed mill operators were extremely concerned that Florida-produced corn would have high levels of
aflatoxin because of climatic conditions. They were also adamant about getting high quality alfalfa hay
with low moisture levels. Interestingly, only one of the interviewees brought up the matter of
radionuclides, and wanted to know the radionuclide levels on crops grown on reclaimed phosphatic clay
lands. Others did not seem very concerned, or did not know anything about this issue.
SUMMARY AND CONCLUSIONS
Florida is a feedstuffs deficit state. Annual consumption far surpasses the state production for
most of feed grains and alfalfa products. Statewide, there is a shortfall of over 32 million bushels of
corn, almost five million bushels of soybean, along with shortfalls in alfalfa products and other feedstuffs.
The production deficits are particularly large within a 200-mile radius of Polk County, indicating a
potential market for these crops if produced on the reclaimed phosphatic clay lands. However, it should
be noted that, due to the homogeneity of the competitive environment in the feedstuff market, producers
will be required to compete on quality and price with crops from other parts of the nation. In assessing
the economic potential of the production of feedstuffs on the reclaimed phosphatic clay lands, the
following items should also be considered:
There have been unfavorable long-term price trends for virtually all hay and grain
crops. Further, technological advances such as genetic engineering may result in
increased production efficiency in traditional growing areas, with little benefit accruing
to growing areas like Polk County. This could increase feed supplies and lower market
Phosphatic clay lands provide several production advantages for feedstuffs, but some
disadvantages as well. Richness in plant nutrients and reduced need for irrigation may
be offset by higher labor and machinery costs bur research with minimum tillage has
been successful and offers promise of holding costs down.
Transportation costs enhance the competitive position on most items. However, the
transportation advantage is lost for soybeans if they must be transported to a crushing
mill for processing into soybean meal because the nearest terminal market is in north
Florida. It is feasible to "cook" or "roast" soybeans to enhance their feed value and this
may be a viable alternative for some Florida feeding operations.
Quality is another significant factor in determining market opportunities. Aflatoxin
and moisture levels in Florida-produced corn and alfalfa hay are concerns to feed
manufacturers. Most were not concerned with radionuclides. However, radionuclide
may emerge as a negative factor even though most evidence to date indicate that food
and feed products produced on reclaimed mined phosphatic clay lands pose virtually
no health risks. Future production research should also attempt to objectively measure
the quality of hay and grain products from reclaimed phosphatic clay soils.
Total production costs discussed in this report are understated because land
reclamation and preparation costs allocable to agricultural production or rental rates
are not addressed. For milo, wheat and soybeans, imposition of a modest land charge
would result in negative returns.
Production costs and yields should be viewed as tentative because they were derived
from relatively small research trials over a relatively short time period. Expansion to
a commercial scale and adoption of no-till or minimum tillage system may yield
In conclusion, this study indicates that there is a ready Florida market for the feedstuffs
examined. Based upon the limited cost and yield data, there appears to be greatest promise for
economical production of corn and alfalfa. However, as cultural problems on reclaimed lands are solved
and as additional data are obtained from research, costs and returns should be reexamined for all feed
