Eff ective Food Plots for White-Tailed Deer in Alabama
Introduction
    Of all the management practices available for improving white-tailed deer habitat, none is more
popular in Alabama than planting agricultural crops in food plots. Millions of dollars are spent on
growing agricultural crops for deer each year. Historically, most food plots were planted with small
grains in the late-summer or early-fall. These food plots were planted primarily to attract deer to the
gun or bow during hunting season. Food plots now are an integral part of many intensive deer
habitat management programs. Today, more and more deer hunters and deer managers plant food
plots for reasons other than hunting only. Cool-season food plots are planted with highly nutritious
crops to help deer through nutritionally stressful periods. Warm-season crops are planted to provide
high-protein, high-quality food during the antler growing and fawn producing periods of spring and
summer. Warm-season crops also are planted to help deer through the nutritionally stressful late-
summer/early-fall period.
    Food plots planted for deer also benefit many other species of wildlife. In addition to the obvious
increase in food production, food plots increase habitat diversity in forested landscapes by creating
openings and edge in areas where they normally would not exist. The openings and edges created by
the food plots allow plants that normally cannot survive in a forested landscape to flourish. Soil
disturbance, fertilization, and liming associated with preparing and planting food plots for deer also
enhance the quality and types of native plants that grow along the food plot edges. Many of the
native plants that grow along the edge of food plots provide feeding, nesting, and brood-rearing
habitat for wild turkeys, bobwhite quail, and many other game and non-game species of wildlife.
Regardless of the intended purpose of food plots, planning and preparing for planting food plots for
deer ahead of time provide the most benefit for your investment.

    Unfortunately, estimating food plot size is not
always this simple. Most food plots are odd shaped
and require a little more work to determine their
size. Measure the food plot’s width at several dif-
ferent points parallel across the food plot and then
calculate an average width in feet. Take more
measurements on larger food plots. Do the same
thing to determine an average length. Multiply
the average width by the average length and di-
vide by 43,560 to determine the total acreage. In
FIGURE 2 (page 2), the average width of the food
plot is 165 feet and the average length is 280 feet,
so the estimated acreage is 1.06 acres. Many GPS
units have features that calculate acreage. This
makes measuring any shape easy.

grasses and broadleaf plants. Only dry brittle plant
material remains at planting time. In many in-

closely mowing the dead vegetation makes tilling

mowing the dead vegetation also prepares food plots
for planting with a no-till planter. Plowing, discing,

for most cool-season food plots, since most cool-sea-

quality warm-season forages are deep-rooted                     A moldboard or bottom plow deeply buries unwanted

                     Cool-Season Crop Choices
     Crop choices for cool-season food plots are de-
termined by the purpose of the planting. Hunting
food plots should be planted with crops that are pal-
atable and productive during hunting season. The
various small grains, including wheat, oats, rye, and
triticale, are the most common choices. Other
choices include winter peas (e.g., Austrian winter
peas) and the many plants in the Brassica family
(e.g., rape, kale, turnips). These crops are quickly
established, highly productive, and attractive to deer
throughout hunting season.
     Cool-season food plots planted primarily to feed
deer during the nutritionally stressful winter and
early-spring period should include later maturing
crops, in addition to small grains. The various spe-
cies of clovers make excellent additions to cool-sea-           Plant a combination of crops (e.g., small grains, clovers,

the legumes and stored in nodules that form on the
plant’s roots. Legumes can fix 100 to 300 pounds of
nitrogen per acre, per year. This process not only
produces enough nitrogen for the legumes, but com-
panion plants, such as wheat, corn, or grain sor-
ghum, also can use some of the excess nitrogen pro-
duced by the legumes.
     Large numbers of these bacteria must be present
in the soil for the nitrogen fixing process to occur
efficiently. This requires inoculating the seeds with
live bacteria. Many of the smaller legume seeds,
such as white clover, ladino clover, alfalfa, and red
clover, come pre-inoculated, but most legume seeds
must be inoculated at planting time. Inoculants are
species-specific (see FIGURE 7), so it is important
to read the package and make sure the correct in-
oculant is used. In addition, make sure the expira-

  FIGURE 8: Helpful Hints for Successful Food Plots

  - After mowing a food plot, be sure to clean weed seeds and other clippings from the mower deck. A small broom
     makes removal of plant debris a relatively quick procedure. This practice helps reduce the spread of weeds and
     other undesirable vegetation from one food plot to the next.

  - If access to water is a problem when spraying herbicides, a 12-volt bilge pump and a 55-gallon drum or large
     garbage can can provide water in remote areas. Mount the bilge pump to a section of PVC pipe, connect a
     sufficient length of flexible bilge hose, and submerge in the water storage tank. A power source (12-volt battery)
     is all that is necessary to refill your spray tank.

  - Be sure to keep extra top-link, lift-arm, and snap-pins on hand. These items often are lost or damaged while
    planting—having spares will save valuable time.

  - Before planting, make sure tractors and implements are properly serviced and in good working condition. Be
    sure to grease all lubrication points and be sure bearings are in good condition.

  - Keep a chainsaw on hand, along with a section of strong chain or rope. Fallen trees and large limbs can be
    cleared in a matter of minutes with this equipment.

  - It is a good idea to have a cellular phone or some other method of communication on hand—they can be lifesavers
     in cases of medical emergency.

  - A basic set of tools is a must and should include a hammer, screwdrivers, adjustable wrench, pliers, and a pipe
     wrench. Many repairs can be handled in the field with these tools—a pipe wrench can make tightening disc
     axles an easy chore.

  - Eye and ear protection are always good ideas. A long day of operating a tractor can take a toll on one’s hearing
     and unseen limbs can cause a serious eye injury. A dust mask will reduce respiratory irritation caused by dust,
     pollen, and other plant residues.

  - Keep bungee cords on hand—they have a variety of uses, including securing tool boxes, water jugs, and empty
    seed and fertilizer bags to trailers, ATVs, and tractor implements.

  - Above all, be safe and take your time. Most accidents and equipment failures are the result of “getting in a
    hurry” to finish the job. An extra hour or even an extra day is well worth preventing injuries or costly repairs.
