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.

This is an area approximately 2
209’ X 209’ or 300’ X 145’. 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.

In nearly all of these situations, reducing the deer population to a level compatible with the habitat is a much wiser management practice than planting warm-season food plots. At least one three-acre or larger warm-season food plot per 160 acres is necessary to provide maxi- mum nutritional benefit to all deer on a property. Food plots should be evenly distributed across the property on a food plot per 160-acre grid (quarter section). If possible, warm-season food plots should be used exclusively for warm-season plantings and not double cropped with cool-season plantings. As with anything, the final determining factors on the size and number of food plots to plant are available time and money.

tilizer recommendations are accurate. Soil types and fertility can vary from one end of a large food plot to the other. Taking only one sample from this food plot can give inaccurate test results. Subsamples from larger food plots should be mixed together in a clean bucket and one sample from the entire food plot should then be taken from these mixed subsamples. On food plots three acres or larger, two or three samples may be needed to get an accurate report from the soil testing lab. Place approximately 1-1/2 to 2 cups of the soil in a container (e.g., cardboard box, paper bag) suit- able for shipping to the soil testing lab. Label the sample with the name of the food plot and the crop to be planted. If more than one food plot is tested and their locations or names are not written on the samples, it will be impossible to match test results with the source food plot. Different crops have dif- ferent pH and nutrient requirements. Make sure the crops to be planted are indicated on the con- tainer so the lab can make the correct recommen- dations. Most soil testing labs charge a small fee (

Tillage Considerations Preparing a firm, smooth seed bed is essential for a good food plot. A good seed bed improves seed to soil contact, improves seed germination, and leads to better crop establishment. This all results in bet- ter forage production. Seed bed preparation starts with the removal of existing vegetation. Mowing or bush-hogging existing vegetation just prior to plowing is the most common way to accomplish this. The biggest prob- lem with mowing just prior to planting is the layer of freshly-cut green vegetation makes it difficult to get adequate soil disturbance with the type of farm implements used by most hunting clubs and small landowners. A very heavy disc harrow can cut and bury the vegetation sufficiently, but most food plots The easiest and quickest way to apply lime is with a for deer are prepared using relatively light equip- large-capacity buggy or spreader truck. These are available at most agricultural supply stores and farmers’ ment. Mowing vegetation two weeks ahead of cooperatives. CHRIS COOK discing or tilling allows enough time for much of the mowed vegetation to decay and break down. This it by the limestone recommendation of the soil test report to determine the amount of these products needed to equal the recommended amount of lime- stone. For example, if a soil test recommends 2 tons (4,000 lbs.) of limestone per acre, only 3,200 lbs. of a product with a CCE of 125 is needed [(100/125) x 4,000 lbs./acre = 3,200 lbs./acre]. Consult with some- one knowledgeable in this field, such as a county extension specialist or someone at an agriculture supply center, before using these products. Apply fertilizer at the time of planting. Fertil- izer is easily applied with a spin-type seed/fertilizer spreader or a spreader buggy. Using the smaller spin-type spreader allows better control of fertilizer distribution than the buggy and generally works best on average-sized food plots. Plow, disc, or till the fertilizer into the soil before applying the seed for best results. Some components Applying a broad-spectrum herbicide, such as of fertilizer, for example phosphorous, are not mobile glyphosate, well ahead of planting makes plowing and preparing a proper seed bed easier.

In many in- stances, mowing is not necessary prior to tilling, but closely mowing the dead vegetation makes tilling the soil with a disc harrow more effective. Closely mowing the dead vegetation also prepares food plots for planting with a no-till planter. Plowing, discing, or tilling the top four to six inches of soil is adequate for most cool-season food plots, since most cool-sea- son crops (e.g., small grains, clovers) are shallow- rooted. Warm-Season Considerations Unlike most cool-season crops, many high- quality warm-season forages are deep-rooted A moldboard or bottom plow deeply buries unwanted plants.

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, son food plot seed combinations.

Planted together, lablab produces nitrogen that in turn benefits the com- panion corn plants. Seeding rates for this combi- nation also are low (5 pounds of corn and 10 pounds of lablab per acre). This makes it a truly economical forage planting. Other simple combi- nations include a mixture of grain sorghum (8 pounds per acre) and cowpeas (40 pounds per acre), or sunflowers (10 pounds per acre) and soy- beans (40 pounds per acre).

Stir the seed to make 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.

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. 16
