How to plant soybeans for a deer food plot

Last updated 2026-07-26

What is a food plot and why plant soybeans specifically?

A food plot is a planted area, usually somewhere between a quarter acre and several acres, that grows forage specifically to feed deer and other wildlife rather than to sell as a cash crop. Landowners and hunters plant them to improve deer nutrition, hold animals on a property, and create hunting opportunities near stand sites. Soybeans are one of the two or three most planted food plot crops in the whitetail world. They're a legume, so they fix nitrogen in the soil and don't need heavy nitrogen fertilizer once established. The USDA lists soybean forage crude protein commonly in the 30-38% range depending on growth stage, which is well above what deer get from most native browse ^[1]. Deer eat the leaves all summer, then the pods and dropped beans become a fat and protein-dense food source into fall and even after frost if enough survives. The catch: soybeans are a browse-tolerant crop only once they get past the seedling stage. A small plot can get hammered flat before it ever produces a pod. That's the single biggest reason first-time soybean plots fail, and it's not really a planting problem, it's an acreage problem.

When should you plant soybeans for a food plot?

Plant soybeans in late spring after your last frost date, once soil temperature is consistently at or above 60°F. In most of the whitetail's range that lands somewhere between late April and early June, with northern states (Wisconsin, Minnesota, Michigan) often waiting until mid to late May and southern states (Texas, Georgia, Alabama) able to plant as early as mid-April. Soybean planting guidance from land-grant universities generally centers on a 50 to 60°F soil temperature threshold for grain production, though food plot growers often wait a bit longer, closer to 60°F, since a slower germinating plot is more vulnerable to early browse pressure while it's still small ^[2]. Don't plant too early. Cold, wet soil rots seed and causes weak stands. A thin stand is exactly what gets wiped out by deer before it can bounce back. Waiting an extra one to two weeks past your region's absolute earliest safe date costs you almost nothing and buys real insurance against a failed plot.

When should you plant food plots for deer in general?

Food plot timing splits into two windows: spring/summer plantings (soybeans, corn, clover, chicory) and fall plantings (brassicas, cereal grains, wheat). Spring plots go in after frost risk passes and soil warms, roughly April through early June depending on latitude. Fall plots go in 60 to 90 days before your area's first hard frost so plants have time to establish before cold shuts down growth. A simple two-plot strategy works for most properties: a spring-planted soybean or clover plot for summer nutrition and antler growth, and a fall-planted brassica or cereal grain plot timed to peak in palatability right around hunting season. Extension programs in the Northeast generally recommend seeding fall brassicas from late July through August so they mature into October and November, when deer preference for them increases after a frost sweetens the leaves ^[3]. Check your local frost dates through your state's cooperative extension office before locking in a date. A soil test taken at planting time (or the fall before) also tells you exactly what lime and fertilizer you need. That lab report is the real authority on your specific dirt, not a generic calendar.

How much soybean seed do you need per acre?

Drilled (rows)	45-60 lbs/acre	More seed-to-soil contact, better germination
Broadcast + cultipack	60-90 lbs/acre	Higher rate needed to offset uneven coverage
Forage-blend soybeans	50-70 lbs/acre	Follow bag rate, blends vary by brand	Purdue University's agronomy guidance places standard grain soybean seeding rates around 140,000 to 160,000 seeds per acre for row crop production, which translates to roughly 50-60 lbs per acre depending on seed size [4]. Food plot soybean blends often run a bit heavier on the broadcast side because germination and seed-to-soil contact are less reliable without a drill. If you're broadcasting, don't skip the cultipacker. At least drag a section harrow over the seed. Soybeans left sitting on top of bare soil dry out fast and birds pick off a lot of what's left.

Seeding rate depends on your planting method. Here's the honest range most extension agronomists and food plot seed companies land on. | Method | Seeding rate | Notes |

What soil pH and fertility do soybeans need?

Soybeans want a soil pH between 6.0 and 6.8. Below 6.0, nutrient uptake drops off and nitrogen-fixing nodules don't form well even with inoculated seed. The University of Missouri Extension states soybean yield potential starts declining measurably once pH drops below 6.0, and recommends lime applications to correct pH be made months ahead of planting since lime takes time to react with soil ^[5]. Because soybeans fix their own nitrogen once nodulated, you generally don't need heavy nitrogen fertilizer. What you do need is phosphorus and potassium if your soil test calls for it, plus lime if pH is low. This is exactly why a soil test matters more for beans than almost any other food plot crop. Guessing on lime wastes money. Guessing on P and K either underfeeds the plant or wastes fertilizer that runs off. Your soil test lab is the real authority here, not a blanket internet recommendation. Send a sample to your state land-grant university's soil testing lab or a private ag lab, and follow their specific lime and fertilizer numbers for your field.

How many acres of soybeans do you need to survive deer browsing?

Most experienced food plot growers and university wildlife extension programs recommend a minimum of 3 to 5 acres for a soybean plot specifically because of browse pressure. Smaller plots, especially under 2 acres, run a real risk of getting eaten to the ground before the plants mature past the vulnerable seedling stage. The logic is straightforward. Deer browse soybean seedlings hard in the first few weeks after emergence. A large plot spreads that pressure out over enough plants that a percentage survives to grow past knee-high, at which point soybeans get much more browse-tolerant and start putting energy into pods instead of just replacing eaten leaves. A tiny plot doesn't have that buffer. Deer can eat every single plant before it escapes the browse zone. If you only have an acre or two to work with, soybeans alone are a gamble. Better options for small acreage include clover, brassicas, or a soybean/corn strip combo where the corn helps shield beans from some browsing while also adding its own forage and cover value later in the season. For a full soybean plot to work as a standalone summer food source, 3+ acres is the realistic floor, and 5+ is safer.

What equipment do you need to plant soybeans?

You don't need a full-size ag operation, but you do need certain basics. A disc or field cultivator to prep seed bed, a way to spread lime and fertilizer (broadcast spreader or having a co-op custom-apply it), a seed drill or broadcast spreader for the beans themselves, and a cultipacker or drag harrow to firm the seed bed afterward. A no-till drill is the gold standard if you can rent or borrow one. It places seed at a consistent 1 to 1.5 inch depth with good soil contact and needs less ground disturbance. If you're broadcasting with an ATV spreader, plan on a heavier seeding rate (see the table above) and make sure you cultipack or drag the field so seed gets covered, not left exposed on the surface. Small ag tractors (25-45 HP) handle most food plot equipment fine for plots under 10 acres. If you're renting equipment for a one-time planting, a local farm co-op or equipment rental yard is usually cheaper than buying gear you'll use once a year.

Do deer eat sorghum, clover, turnips, and oats too?

Yes to all four, though deer preference and timing vary a lot by species and by season. Deer do eat sorghum, mostly the grain heads in fall and winter, and it's more commonly planted as a dove field or wildlife cover crop than a primary deer attractant, since deer generally rank it below soybeans, corn, or brassicas in preference. Grain sorghum also stands through winter better than corn in some regions, which gives it value as standing cover and late-season food. Deer like clover quite a bit, and it's one of the most consistent food plot performers. It's a perennial (with proper maintenance, some clover stands last 3-5 years), it regrows after grazing, and it produces high-protein forage through most of the growing season. The USDA NRCS notes clover forage typically runs 20-25% crude protein depending on variety and cutting stage ^[6], which makes it a strong spring/summer option alongside soybeans, especially on smaller acreage where soybeans alone are risky. When to plant turnips for deer: turnips are a fall brassica, planted roughly 60-90 days before your first expected frost, commonly late July through August depending on latitude. They're a classic late-season food source because a hard frost converts starches to sugars in the leaves and bulbs, which is exactly when deer preference for them spikes. When to plant oats for deer: oats are typically planted in early fall, late August through September in most whitetail range, as a cool-season annual that deer hit hard through fall and into early winter until snow cover gets deep. Oats can also be planted in early spring in northern climates for a quick summer forage window, though fall planting is far more common for hunting-season food plots. Do deer like honey: no meaningful connection here in a food plot context. Deer aren't drawn to honey as a food source in any documented wildlife management literature, and it's not used in food plot mixes or attractants recognized by extension programs. If you've heard of "honey hole" hunting spots, that's just hunting slang for a productive location, not a reference to deer eating honey.

What are deer's favorite foods overall?

There's no single universal answer because preference shifts by season, region, and what's available, but research and food plot data point to a consistent short list: soybeans, corn, clover, chicory, and acorns rank among the most consistently preferred whitetail foods across most of their range. Acorns deserve a specific mention. In years with a good mast crop, deer often ignore planted food plots entirely in favor of white oak acorns, which are lower in tannins and more palatable than red oak acorns. This is well documented in wildlife management circles and is one of the most common reasons a food plot looks "dead" in a heavy mast year. It's not a planting failure, deer just have better food in the woods. Outside of mast years, soybeans and corn provide the highest-energy, highest-volume food sources for summer and fall, clover provides consistent spring-through-fall protein, and brassicas and cereal grains take over as the preferred late-season food once frost sweetens them up. A property that has all three windows covered, summer legumes, fall brassicas or grain, and some natural mast, gives deer a reason to stay year-round instead of just passing through.

How do you plant soybeans step by step?

Here's the basic sequence most food plot growers follow, adjusted for your specific soil test results. First, pull a soil sample 60-90 days before planting if you haven't already, and get it to a lab. Second, apply lime according to that report; lime needs months to fully react in soil, so fall or early spring application ahead of a late spring planting works well. Third, once soil temp hits 60°F and frost risk has passed, prep your seed bed with a disc or cultivator to break up residue and smooth the surface. Fourth, apply any phosphorus/potassium your soil test calls for. Fifth, plant: drill at 1 to 1.5 inches deep at 45-60 lbs/acre, or broadcast at 60-90 lbs/acre and cultipack immediately after. Sixth, if your soil hasn't grown soybeans in the last 3-5 years, use an inoculated seed or add inoculant at planting, since the rhizobia bacteria that let soybeans fix nitrogen need to be present in the soil or added directly. After that, it's mostly patience. Weed control (a post-emergent herbicide labeled for soybeans, if you're not using a Roundup Ready variety) and monitoring browse pressure are the main things to watch in the first six weeks. If you want a planting plan built around your specific soil test numbers, acreage, and region, a Custom Food Plot Plan walks through species selection and rates for your exact property for a one-time $99 fee. It's general planning guidance built from your inputs, not a substitute for your soil lab's specific lime and fertilizer recommendations.

What mistakes cause soybean food plots to fail?

The most common failure is simple: too small an acreage relative to deer density. A half-acre soybean plot in an area with a healthy deer herd often gets eaten down before it ever produces a pod. This isn't a planting mistake, it's a design mistake, and the fix is either more acreage or a different, more browse-tolerant crop for that spot. The second most common mistake is planting too early into cold soil, which causes rot and weak, spotty stands, or too late, which pushes maturity into fall frost before pods fill out. The third is skipping the soil test and guessing on lime, which either leaves pH too low for good nodulation and nutrient uptake, or wastes money over-applying fertilizer the soil didn't need. Weed competition is a quieter killer. Soybeans compete poorly with grass and broadleaf weeds in the first few weeks, and a weedy plot loses a big chunk of its yield potential before you even notice a problem. If you're not planting a Roundup Ready variety, plan on a pre-emergent or early post-emergent herbicide application labeled for soybeans.

Should you check state rules before planting a food plot?

Yes. Food plots themselves are legal planting activity nationwide, but baiting and supplemental feeding rules vary a lot by state, and some states draw a line between what counts as a food plot versus what counts as baiting, especially around minimum plot size, distance from a stand, or whether the crop is standing versus piled. Check your state wildlife agency's regulations before you plant, especially if you're combining a food plot with any supplemental feed, mineral, or attractant use nearby. Rules differ enough state to state that a blanket national answer would be misleading. Your state fish and wildlife or natural resources agency page is the correct source to check every season since rules do get updated.

Frequently asked questions

Do deer eat sorghum?

Yes, deer eat sorghum, mainly the grain heads in fall and winter, but it typically ranks below soybeans, corn, and brassicas in deer preference. It's more often planted as dove field cover or a winter standing crop than as a primary deer food plot species.

Do deer like clover?

Yes, clover is one of the most consistently preferred food plot forages. It's high in protein (commonly 20-25% crude protein per USDA NRCS data), regrows after grazing, and can persist as a perennial stand for 3-5 years with proper mowing and fertility maintenance.

When should you plant food plots for deer?

Spring/summer plots like soybeans, corn, and clover go in after your last frost once soil hits roughly 60°F, typically April through early June depending on latitude. Fall plots like brassicas and cereal grains go in 60-90 days before your first hard frost, usually late July through September.

When should you plant turnips for deer?

Plant turnips 60-90 days before your area's first expected fall frost, commonly late July through August in most whitetail range. Turnips are a fall brassica that becomes more palatable after frost converts starches to sugars in the leaves and bulbs.

When should you plant oats for deer?

Oats are usually planted in early fall, late August through September, as a cool-season annual that deer eat through fall into early winter. Some northern growers also plant oats in early spring for a quick summer forage window, but fall planting is more common for hunting-season plots.

What is a food plot?

A food plot is a planted area, usually a quarter acre to several acres, seeded specifically to feed deer and other wildlife rather than for commercial harvest. Common food plot crops include soybeans, clover, brassicas, cereal grains, and corn, chosen based on season and property goals.

What are deer's favorite foods?

Preference shifts by season and region, but soybeans, corn, clover, chicory, and acorns rank consistently high. In years with a heavy acorn crop, deer often prefer white oak acorns over planted food plots entirely, since white oak acorns have lower tannin levels than red oak acorns.

Do deer like honey?

No, there's no documented connection between deer and honey as a food source in wildlife management literature. Deer aren't drawn to honey, and it isn't used in any recognized food plot mix or attractant program.

How many acres of soybeans do you need for a food plot?

Most food plot growers and extension resources recommend a minimum of 3 to 5 acres for a standalone soybean plot. Smaller plots risk getting browsed to the ground before plants mature past the vulnerable seedling stage, since soybeans only become browse-tolerant once established.

What soil pH do soybeans need for a food plot?

Soybeans grow best at a soil pH between 6.0 and 6.8. Below pH 6.0, nutrient uptake and nitrogen-fixing nodule formation both decline, so a soil test and, if needed, a lime application months ahead of planting matter more for soybeans than for many other food plot crops.

How deep and how much soybean seed should you plant per acre?

Drill soybeans 1 to 1.5 inches deep at 45-60 lbs per acre, or broadcast at 60-90 lbs per acre followed by cultipacking. Standard grain soybean seeding rates run around 140,000 to 160,000 seeds per acre according to Purdue University agronomy guidance.

Do soybean food plots need nitrogen fertilizer?

Not much. Soybeans are legumes and fix their own nitrogen through root nodules once inoculated bacteria are present in the soil. Focus fertility on phosphorus, potassium, and lime according to your soil test rather than heavy nitrogen applications.
