How to plant soybeans for food plots (a full guide)

Last updated 2026-07-26

What is a food plot, and why plant soybeans in one?

A food plot is a planted patch of forage, usually somewhere between a quarter-acre and several acres, put on private or leased land specifically to feed and hold deer through part or all of the year. It is not the same thing as a agricultural field, even though the tools and seed sometimes overlap. Most hunters run food plots for two different jobs: a spring/summer plot that grows tonnage during antler growth and lactation, and a fall/winter plot that stays attractive once bow season opens. Soybeans do the first job about as well as anything you can plant. A well-fertilized soybean plot can produce several tons of forage per acre through summer, and the beans themselves (the actual seed pods) become a high-energy food source in fall once the plant matures and drops leaves. Soybean forage commonly runs 30-40% crude protein in the vegetative stage, based on university forage trial work, which is why deer hammer young soybean plots hard in June and July ^[1]. The tradeoff: soybeans get eaten to the ground by deer before they ever get established, especially in small plots or high-deer-density areas. That is the single biggest reason soybean food plots fail. Plan for it or don't bother planting beans in anything under 3-5 acres unless you can fence a section off while it establishes.

When should you plant food plots for deer, and how does that change for soybeans?

Timing for any food plot depends on what you are growing and your climate zone, not a single calendar date. Spring/summer annuals like soybeans, cowpeas and sunflowers go in after your last frost date, when soil temperature is warm enough for good germination. Fall plots (brassicas, cereal grains, clover) go in late summer to early fall, timed backward from your first frost. For soybeans specifically, land-grant university agronomy guidance generally recommends planting once soil temperature at planting depth reaches at least 50°F, with 60°F being a safer target for faster, more even emergence. That typically lines up with: - Deep South (zone 8-9): mid-April through May

• Mid-South / Transition zone (zone 7): late April through mid-May
• Midwest / Mid-Atlantic (zone 6): mid-May through early June
• Northern tier (zone 3-5): late May through mid-June Soybeans need roughly 100-140 frost-free days to reach full maturity, depending on the relative maturity group of the variety, so back that number off your first fall frost date to make sure pods actually fill and dry down before a hard freeze. If you're weighing beans against other summer annuals or fall options, food plot whitetail planning guides break down the full-season options.

How do you prepare soil for a soybean food plot?

Start with a soil test, every time. A $10-20 soil test through your county Extension office or a private ag lab tells you your actual pH and nutrient levels, and that report is the real authority on how much lime and fertilizer your specific dirt needs, not a bag label or a blog post. Soybeans want pH between 6.0 and 6.8. Below 6.0, nitrogen-fixing rhizobium bacteria on the roots slow down and the plant struggles to make its own nitrogen, according to Iowa State University Extension and Outreach soybean production guidance, which notes soybean yield and nodulation both decline as soil pH drops below the optimal range ^[2]. If your test comes back at 5.2 or 5.5, which is common on wooded, never-limed ground, you likely need 1-2 tons of ag lime per acre, and that lime takes months to fully react with the soil, so apply it as far ahead of planting as you can, ideally the prior fall. Bed prep itself is simple: kill existing vegetation (glyphosate on a green field works fine), disk or till to break up sod, and work the ground into a reasonably fine, level seedbed. Soybeans don't need a perfect seedbed like a lawn, but a rough, clumpy field kills stand establishment. If you're planting no-till into a killed cover crop or old field, a drill designed for no-till residue does the job without disking at all.

What seeding rate and planting depth work best for soybeans?

Broadcast + cultipack	60-90 lbs/acre	1-1.5 inches, pressed in
Drilled (7.5-15 in rows)	45-60 lbs/acre	1-1.5 inches
No-till drill	45-60 lbs/acre	1-1.5 inches	Food-plot rates run heavier than commercial ag rates (which are often 30-45 lbs/acre in wide rows) because thicker stands help soybeans outcompete deer browsing pressure and weeds, and because food plotters generally broadcast rather than precision-plant. Depth matters more than most people think. Soybeans planted deeper than 2 inches struggle to emerge, especially in heavier clay soils that can crust over after rain. Shallow planting (under half an inch) leaves seed exposed to birds, drying out, or getting scratched up. A drill gets this right automatically; broadcast-and-cultipack setups need a light disking or dragging pass before the cultipacker to bury seed at the right depth.

For food plots (as opposed to row-crop agriculture, which uses lower rates and wider rows), most seed suppliers and Extension guidance recommend: | Method | Seeding rate | Planting depth |

How do you protect soybean plots from deer browsing pressure?

This is the real bottleneck on soybean food plots, and it's worth being honest about it upfront: in high deer density areas, small soybean plots often get grazed to nothing before they ever reach knee height. A few field-tested approaches: Plant big. Three to five acres or more gives beans enough total leaf area that browsing pressure gets diluted across the whole plot instead of concentrated on a few plants. A half-acre plot in a high-deer area is a salad bar, not a crop. Use a nurse crop or blend. Mixing soybeans with a small amount of grain sorghum or corn can add structure and some early cover, though it won't stop browsing on its own. Temporary electric fencing around 20-40% of the plot until plants reach 12-18 inches tall, then open it up, is a technique several state wildlife agencies and university extension wildlife programs mention for establishing soybean and other legume plots under heavy pressure. It is extra cost and labor, but it is the most reliable fix if your plot keeps failing to establish. Plant later relative to green-up. Some hunters intentionally plant soybeans a couple weeks after neighboring ag fields green up, so deer have alternative food and less concentrated pressure on the new plot.

Do deer eat sorghum, and how does it compare to soybeans?

Yes, deer eat grain sorghum, both the standing plant as browse when young and the grain heads once they mature in fall. Sorghum is more drought-tolerant than corn and often gets used as a summer annual or as a nurse crop mixed with soybeans, since its stiffer stalks give beans something to lean against. As a straight forage comparison, soybeans generally offer higher crude protein during the growing season (30-40%) versus sorghum's lower protein but higher carbohydrate/energy content once it heads out, which matters more in late fall and winter ^[1]. Sorghum also tolerates poorer, sandier soils and drought better than soybeans, which need consistent moisture through pod fill. If your ground is marginal or you're in a drought-prone region, sorghum or a sorghum/soybean blend may outperform a pure bean stand.

Do deer like clover, and how does it compare to soybeans in a food plot rotation?

Deer readily eat clover, and it is one of the most consistently productive food plot forages available, largely because it is perennial (lasting 3-5 years per planting) and keeps regrowing after grazing, unlike an annual that gets eaten once and is done. Clover (white clover, red clover, and ladino types are the common food plot species) typically runs high in protein, often 25-30%, similar to young soybeans, according to University of Georgia Extension forage trial data on clover for wildlife plots ^[3]. The difference in a plot rotation: soybeans are a one-season, high-tonnage summer crop that also gives you a fall/winter bean-pod food source, while clover is a long-term, lower-maintenance planting that provides spring through fall forage year after year without replanting. Many food plotters run both: soybeans or corn in bigger, better-drained fields for tonnage and fall grain, and clover in smaller, shadier, or harder-to-access plots where a perennial stand makes more sense. If you're deciding between them for a specific plot, deer food plots covers how to match forage type to plot size and soil.

When should you plant turnips, oats, and other fall companions?

Turnips, oats, and other brassicas and cereal grains are fall-planted, not spring-planted, and they run on a completely different calendar than soybeans. Turnips: plant 60-90 days before your first fall frost, which for most of the whitetail range means late July through early September. Turnip tops become more palatable to deer after a hard frost, when starches convert to sugars, which is why turnip plots often don't get hit hard until October or November. Oats: plant 6-8 weeks before first frost, generally August through mid-September for most of the Midwest and Northeast, a bit later in the South. Oats are attractive almost immediately after emergence and stay green and palatable into early winter until a hard freeze knocks them back. Because soybeans are killed by the first frost and finish their usable browse life around then (aside from dropped beans on the ground), a lot of food plotters plant soybeans in a field one year and rotate to oats, wheat, or brassicas the following fall in the same ground, or plant a fall blend in an adjacent plot so there's always something green available as beans mature and dry down.

What do deer actually prefer to eat, and where do soybeans rank?

Deer are selective browsers, and preference shifts by season, region, and what's locally available, so there's no single universal answer, but research and food plot trial data point to a consistent short list: soybeans, clover, chicory, cowpeas, and acorns rank among the most consistently preferred whitetail foods across most of the whitetail's range ^{[1] [3]}. Acorns deserve a mention because in years with a heavy mast crop, deer will 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 a real, well-documented pattern in deer research and it explains why a food plot that got hammered last October might see almost no traffic this year if the oaks dropped hard. Among planted forages, soybeans and cowpeas typically top preference trials during the growing season because of their high protein and palatability while actively growing, with clover a close second because of its season-long availability ^[1]. Corn, in contrast, is lower in protein but higher in carbohydrate energy, which is why deer key on it more heavily in late fall and winter when they need calories to handle cold.

Do deer like honey, and does that matter for food plots?

No, this isn't really a food plot question, deer don't naturally seek out honey and it has no role in deer forage or food plot planning. It sometimes comes up because of "deer honey" style commercial attractant products, which are usually molasses-based liquid sprays used on the ground or on existing browse to add sweetness and scent, not something planted as a crop. There's no meaningful research showing sprayed sugar-based attractants change deer use of a planted food plot; a well-grown soybean or clover stand does far more work than any liquid attractant sprayed on top of it.

What fertilizer do soybeans need, and how much should you apply?

Because soybeans fix their own nitrogen through rhizobium bacteria on the root nodules, they need far less nitrogen fertilizer than corn, sorghum, or brassicas, once nodulation is working. Most Extension guidance recommends a starter application of phosphorus and potassium based on your soil test, plus a light nitrogen starter (20-30 lbs/acre) only if your soil is very low in organic matter or you're planting into ground with no history of legumes, since the rhizobia bacteria may need time to establish ^[2]. If you've never grown soybeans, cowpeas, or another legume on that ground before, consider using an inoculated seed (soybean-specific rhizobium inoculant, often sold pre-coated on the seed or as a powder you mix in before planting). Without the right rhizobium strain present in the soil, nodulation can be weak and the crop will need supplemental nitrogen to compensate, according to Iowa State University Extension and Outreach guidance on soybean inoculation ^[2]. Beyond N-P-K, your soil test may flag other issues: low pH (fix with lime, as covered above), or deficiencies in sulfur or micronutrients like boron and manganese that show up more often in food plot ground than in well-managed row-crop fields. The test report from your lab is the real word on rates for your dirt; a general guide like this one can only give you the range, not your number. This is exactly the gap a $99 one-time Custom Food Plot Plan is built to close: you get species and rate recommendations mapped to your soil test, your zone, and your acreage, instead of guessing off a bag label.

What equipment do you actually need to plant soybeans?

Minimum viable setup: a way to kill existing vegetation (sprayer, even a small ATV-mounted boom sprayer works for plots under 5 acres), something to work the seedbed (disk harrow or tiller), a way to broadcast seed (handheld spreader for small plots, ATV/UTV spreader for bigger ones, or a drill if you have access to one), and a cultipacker or drag to press seed into contact with soil. A no-till drill is the single best upgrade if you can rent, borrow, or split the cost of one with other hunters in your area. It cuts your steps from four (spray, till, broadcast, pack) to two (spray, drill), gets consistent seed depth, and usually gets better stand establishment per pound of seed planted, meaning you can often drop your seeding rate and still get a good stand. Many farm co-ops and Extension offices maintain rental equipment programs for exactly this reason; check with your local Soil and Water Conservation District office, since a lot of them run no-till drill rental programs for small acreages. If you're broadcasting by hand or ATV spreader, don't skip the cultipacking step. Seed sitting on top of bare dirt with no seed-to-soil contact is the single most common reason a broadcast soybean plot fails to come up evenly, more common than a bad seeding rate or bad timing.

How much does a soybean food plot cost per acre?

Costs vary a lot by region and whether you're renting or already own equipment, but a rough per-acre budget for a soybean food plot commonly lands in the $80-200/acre range for seed, lime, and fertilizer combined, not counting equipment ownership or fuel. Food-plot-specific soybean seed (often a taller, more deer-plot-optimized variety than standard ag beans) typically runs $1.50-3.00 per pound, and at a 50-70 lb/acre seeding rate that's roughly $75-210 per acre in seed alone before lime or fertilizer. Lime is often the biggest single line item on first-year ground, since ag lime runs somewhere around $30-50 per ton delivered and spread in a lot of regions, and a low-pH plot may need 1-2 tons per acre. That's a cost you generally only pay once every 3-4 years, since lime's effect on pH lasts a while, unlike annual fertilizer. If you're planning multiple plots or comparing soybeans against other species for your specific acreage and budget, deer food plot seed and food plot seed break down per-species costs and blends in more detail.

Frequently asked questions

Do deer eat sorghum in food plots?

Yes. Deer browse young grain sorghum plants and eat the mature grain heads in fall and winter. Sorghum tolerates drought and poor soil better than soybeans, making it a good nurse crop or standalone option on marginal ground, though it generally runs lower in protein than soybeans during the growing season.

Do deer eat clover, and is it better than soybeans?

Deer eat clover readily and it is one of the most reliable food plot forages, running 25-30% crude protein and lasting 3-5 years per planting as a perennial. Soybeans offer higher summer tonnage and a fall grain source but are annual and vulnerable to overbrowsing. Many hunters plant both for different plots and seasons.

When should you plant food plots for deer?

Timing depends on the species. Spring/summer annuals like soybeans, corn, and cowpeas go in after your last frost date, generally April through June depending on zone. Fall annuals like brassicas, oats, and cereal grains go in late summer to early fall, roughly 60-90 days before your first fall frost.

Do deer like clover more than other food plot options?

Deer show strong, consistent preference for clover across most of the whitetail range because of its high protein content and season-long availability. It's not universally their single favorite (soybeans and cowpeas often rank as high or higher during the growing season), but clover's perennial nature makes it one of the most dependable plantings overall.

When should you plant oats for deer food plots?

Plant oats 6-8 weeks before your area's first fall frost, which is typically August through mid-September across most of the Midwest and Northeast and a few weeks later in southern zones. Oats are attractive almost as soon as they emerge and stay green well into early winter.

When is the best time to plant soybeans for food plots?

Plant soybeans after your last spring frost date once soil temperature reaches at least 50-60°F, generally mid-April in the Deep South through mid-June in the northern tier. Soybeans need roughly 100-140 frost-free days to fully mature, so count backward from your first fall frost too.

When should you plant turnips for deer?

Plant turnips 60-90 days before your first fall frost, usually late July through early September for most whitetail range. Turnip tops become sweeter and more attractive to deer after a hard frost converts starches to sugar, so heavy use often doesn't start until October or November even though the plant is up earlier.

What exactly is a food plot?

A food plot is a planted area, usually a quarter-acre to several acres, established specifically to provide forage that attracts and feeds deer, rather than a commercial agricultural crop. Plots are typically split into spring/summer plantings (soybeans, corn, clover) for tonnage and growth, and fall/winter plantings (brassicas, cereal grains) for hunting season attraction.

What are deer's favorite foods overall?

Preference shifts by season and region, but research and field trials consistently rank soybeans, clover, cowpeas, chicory, and acorns among whitetail's most preferred foods. In years with a heavy acorn crop, deer often favor white oak acorns over any planted food plot, since white oak acorns are lower in tannins and more palatable than red oak acorns.

Do deer like honey or sugar-based attractants?

Deer don't naturally seek out honey, and there's no solid research showing sugar or molasses-based liquid attractants meaningfully change deer use of a food plot. A well-established, properly fertilized planting like soybeans or clover does far more to attract and hold deer than any liquid attractant sprayed on the ground.

How many pounds of soybean seed do I need per acre for a food plot?

Broadcast plantings generally run 60-90 lbs/acre, while drilled plantings run 45-60 lbs/acre, higher than standard row-crop agriculture rates because food plot stands need to be thick enough to survive deer browsing pressure during establishment. Always plant into a firm, cultipacked seedbed at 1-1.5 inches deep.

Can you plant soybeans without fencing them off from deer?

Yes, but in high deer density areas small unfenced soybean plots often get browsed down before they establish. Planting larger acreage (3-5+ acres) dilutes browsing pressure across more plants. Temporary electric fencing around part of the plot until beans reach 12-18 inches tall is a common fix recommended by several state wildlife and university extension programs.

Do I need to check my state's food plot or baiting rules before planting?

Yes. Some states regulate or restrict supplemental feeding and what counts as legal hunting over a planted food plot versus a baited site, and rules vary widely. Check your state wildlife agency's hunting regulations before planting near a stand or blind you plan to hunt over.
