How much fertilizer per acre for deer food plots

Last updated 2026-07-25

How much fertilizer per acre do deer food plots actually need

There's no single number that works everywhere, and anyone who gives you one flat rate without asking about your soil is guessing. That said, most food plot blends (clover, brassicas, cereal grains) respond well to somewhere between 200 and 400 pounds per acre of a complete fertilizer, split between a base application and sometimes a topdress later in the season ^[1]. For a legume like clover or alfalfa, you generally want low nitrogen (legumes fix their own from the air) but higher phosphorus and potassium, often something like 0-20-20 or a similar low-N blend at 200-300 lbs/acre ^[2]. For brassicas (turnips, radishes) and cereal grains (oats, wheat, rye), nitrogen matters a lot more, and a complete blend like 19-19-19 or 13-13-13 at 300-400 lbs/acre is a common starting rate, sometimes followed by a nitrogen topdress of 30-50 lbs of actual N per acre once the plants are established ^[2]. Here's the honest truth: these are ballpark numbers for someone with no soil test at all. Your actual field could need double that phosphorus, or almost none. Soil varies enormously even within the same county, sometimes within the same 5-acre field. That's why the single best dollar you'll spend on a food plot isn't seed. It's a soil test. A basic soil test through your state's land-grant university extension office typically costs somewhere in the $7 to $20 range depending on the state and how many nutrients they test for ^[3]. That test comes back with actual lbs/acre recommendations for N, P, and K based on what your soil already has and what your target crop needs, which beats any generic chart you'll find online, including this one.

What does a soil test actually tell you, and why trust it over a chart

A soil test measures your field's current pH and nutrient levels (phosphorus, potassium, and sometimes micronutrients like sulfur, calcium, and magnesium) and compares them against the requirements of the specific crop you tell the lab you're planting. Nitrogen usually isn't measured directly in a basic test because it moves through soil too fast to give a stable reading, so N recommendations are based on crop type and expected yield instead ^[4]. Most university extension soil test reports come back as a straightforward table: current level, optimum level, and a fertilizer recommendation in lbs/acre of N-P-K or a specific product rate. University of Wisconsin-Madison Extension's nutrient application guidelines note that soil test phosphorus and potassium recommendations are built to bring soil to a level where yield response to added fertilizer becomes minimal, meaning you're not paying for nutrients the soil already has plenty of ^[5]. This matters for a food plot budget more than people realize. If your soil already tests high in phosphorus (common in fields that have been fertilized for years, or old ag ground), buying a high-phosphorus blend is money down the drain. If it's low in potassium, skipping that nutrient means your clover stand thins out by year two no matter how much nitrogen you throw at it. The lab is the authority here, not a blog post, not a bag tag, and not us. Every plan or recommendation you read online, including this one, is general guidance. Your soil test results, interpreted by your state extension service, are site-specific. Follow those numbers first.

How much does lime matter compared to fertilizer

Lime often matters more than fertilizer, and it's the step most first-time plotters skip. If your soil pH is below about 6.0, plants can't access the phosphorus and potassium you just paid for, no matter how much you spread . Clover in particular wants a pH between 6.0 and 7.0 for the best nitrogen fixation and stand longevity, according to Mississippi State University Extension's food plot guidance ^[2]. Brassicas are a bit more forgiving but still perform best above pH 6.0. If your test comes back at 5.2 or 5.5, which is common on wooded or previously unmanaged ground, you may need 1 to 2 tons of ag lime per acre to correct it, and lime takes months to fully react in the soil, so fall applications for a spring planting (or vice versa) work better than trying to lime and plant the same week. The frustrating part is that lime is heavy, cheap per ton, but expensive to haul and spread if you don't have your own spreader. Many co-ops will deliver and spread it for a fee if you're buying by the ton. It's worth calling around before assuming you need to do it yourself with a bag spreader and a four-wheeler.

What fertilizer blend should I use for clover, brassicas, or cereal grains

Clover / alfalfa (legumes)	0-20-20 or similar low-N	200-300 lbs/acre	Low nitrogen needed; legumes fix their own [2]
Brassicas (turnips, radishes)	19-19-19 or 13-13-13	300-400 lbs/acre	May benefit from N topdress at 4-6 weeks [2]
Cereal grains (oats, wheat, rye)	19-19-19 or 46-0-0 topdress	200-300 lbs/acre base, 30-50 lbs N topdress	Nitrogen drives tonnage and leaf growth [2]
Mixed blend / "throw and grow"	13-13-13 general purpose	200-300 lbs/acre	Compromise rate across species in the mix	If you're planting a mix, like a brassica-clover blend or an oats-clover combo, a general 13-13-13 at around 300 lbs/acre is a reasonable middle ground, understanding you're not optimizing for any single species perfectly. For readers comparing food plot seed options against their fertility budget, it often makes sense to buy the soil test first, then let the results drive both seed choice and fertilizer purchase together rather than buying seed and fertilizer as two separate decisions.

The right blend depends heavily on species, so here's a rough comparison based on common university extension recommendations. These are starting points, not gospel. Your soil test overrides all of them. | Plot type | Typical blend | Typical rate | Notes |

When to plant food plots for deer

Timing depends on your zone and what you're planting, but the two big windows are late summer for fall/winter plots and spring for summer annuals or perennial establishment. Get this wrong and even perfect fertility won't save the plot. For fall plots (brassicas, cereal grains, clover establishment), most of the whitetail range plants somewhere between mid-July and early September, timed so the plot has 60 to 90 days of growing season before a hard frost, since brassicas in particular need that runway to bulb out and sweeten ^[2]. Northern states (Zone 3-4) often plant as early as late July; southern states may wait until late August or September. Spring plots (soybeans, cowpeas, summer annual clovers, or perennial clover establishment) typically go in after the last frost date, which varies widely: late April in the Deep South, late May or even early June in the Upper Midwest and Northeast. Check your state extension's planting date guide or frost date tables for your specific county rather than relying on a national rule of thumb, since a two-week difference can matter a lot for brassica bulb size or clover germination.

When to plant oats for deer

Oats are a fall-plot staple and typically go in the ground 6 to 10 weeks before your area's first expected hard frost, which lines up with roughly early August in the northern whitetail range down to mid-September in parts of the South ^[2]. Oats germinate fast, often within 5-7 days in good moisture, and deer will hit young oat shoots hard, sometimes before anything else in the plot has emerged. Oats don't handle deep winter cold as well as winter wheat or cereal rye, so in the northern half of the country they're often used as a fall attraction crop that dies back with hard freezes rather than a plant meant to survive to spring. If you want green growth into late winter, blending oats with winter wheat or rye hedges that bet. A starter fertilizer at planting (part of that 200-300 lbs/acre complete blend range) followed by a nitrogen topdress a few weeks in will push leafier, more attractive growth, since nitrogen is the main driver of oat forage tonnage ^[2].

When to plant turnips for deer

Turnips are a brassica and go in during that same late-summer window, generally 80 to 90 days before your first hard frost, since the bulb needs time to size up and the plant needs a frost or two to convert starches to sugars, which is when deer really start hammering them ^[2]. Plant too late and you get greens but no bulb; plant too early in hot, dry soil and germination suffers. Most of the whitetail range plants turnips somewhere between mid-July (far north) and early September (Deep South). Turnips like a firm, well-drained seedbed and a pH above 6.0, and they're heavier feeders on nitrogen and boron than people expect, so a soil test that flags a boron deficiency is worth taking seriously since boron deficiency causes hollow, cracked bulbs ^[2]. For readers building a broader plan around brassicas alongside other species, see deer food plot seed for how turnips typically get blended with radishes or clover.

Do deer eat sorghum, and is it worth planting

Yes, deer will eat sorghum, particularly the grain heads once they mature, and sorghum is sometimes used as a summer food plot component or as a screening/cover crop in food plot borders. It's more drought-tolerant than corn, which makes it attractive in dry regions or sandy soils where corn struggles . That said, sorghum isn't usually a top-tier attraction crop compared to soybeans, clover, or brassicas. Deer will browse young sorghum shoots and eat the grain later in the season, but it's rarely the plant that pulls deer past everything else in a mixed plot. It's more commonly used for its agronomic benefits (drought tolerance, biomass, screening cover) than as the main draw. If you're set on sorghum, treat its fertility needs similarly to corn: it's a nitrogen-hungry grass crop and benefits from a complete blend at planting plus a nitrogen topdress, generally in the 200-300 lbs/acre base range depending on soil test results.

Do deer eat clover, and do they actually like it

Yes, and clover is consistently ranked as one of the most preferred, most planted food plot forages in the whitetail world. It's high in protein (often 20-30% crude protein in good stands), stays palatable through most of the growing season, and as a perennial it can produce for 3-5 years or more before needing to be replanted, unlike annuals that need reseeding every year ^[2]. Mississippi State University Extension notes clover's popularity comes down to a combination of high forage quality and season-long availability, which is a big reason it shows up in nearly every food plot mix on the market ^[2]. It's also relatively cheap to maintain once established, since annual maintenance is mostly mowing, spot-spraying grass competition, and a maintenance fertilizer application rather than full replanting. The catch: clover is slower to establish than a fast annual like oats, needs decent soil pH (6.0-7.0) to thrive, and can get shaded out or choked by weeds if you don't stay on top of mowing in year one. For readers deciding between clover and other perennial or annual options, deer food plots covers the broader species tradeoffs.

What is a food plot, exactly

A food plot is a planted area, usually somewhere between a quarter acre and several acres, established specifically to provide supplemental forage for deer and other wildlife, distinct from natural browse or agricultural fields grown for harvest and sale. Food plots are typically planted with forages selected for high palatability and nutrition (clover, brassicas, cereal grains, soybeans) rather than for maximum yield or market value. State wildlife agencies generally treat food plots as a legal, common wildlife management practice distinct from baiting, though the line between the two varies by state and matters a lot if you hunt over or near the plot. Some states classify a standing, unharvested crop planted specifically for wildlife differently than a pile of corn or minerals dumped on the ground; others restrict both under similar rules. Check your specific state wildlife agency's regulations before hunting a plot, since baiting and feeding rules vary significantly and violations can carry real penalties. Beyond the hunting-legality angle, food plots serve a genuine habitat function: they add nutrition during stress periods (late winter, antler growth, lactation), and they concentrate deer activity in observable, huntable locations, which is why most serious land managers treat plot planning as part of a broader deer management plan rather than a standalone project. For a broader look at how plots fit into overall land strategy, see food plot whitetail.

What are deer's favorite foods, and does that change by season

Deer preference shifts hard by season, which is exactly why serious plot plans mix multiple species rather than betting on one. In spring and summer, deer favor high-protein browse, forbs, soybeans, and cowpeas to support antler growth and lactation. In fall, acorns often become one of the most preferred food sources where available, and deer will frequently favor a good acorn drop over a planted plot . In late fall and winter, brassicas (especially after a frost sweetens them), cereal grains, and standing soybean pods become primary draws, since energy and carbohydrate needs rise as temperatures drop. Clover holds up as a near-constant preferred forage across most of the growing season when it's available and not dormant. There's no single "favorite" food that holds true everywhere, every season, for every deer herd. Regional food availability, ag field proximity, and acorn crop strength in a given year all shift what a local herd prefers most. That's part of why a one-species food plot is riskier than a mix; if your one species isn't preferred that particular fall, the plot underperforms.

Do deer like honey, and does it matter for food plots

There's no meaningful evidence that deer specifically seek out honey, and it's not a practical or common food plot or attractant strategy. Deer are herbivores whose diet is built around browse, forbs, mast (acorns, other nuts), agricultural crops, and forage plants; honey isn't part of natural whitetail diet and isn't recommended by any wildlife agency or extension source as a food plot or attractant approach. If you've seen anecdotal claims about deer and honey or sugar-based attractants, keep in mind that many states regulate or ban baiting and feeding with any additive, including sugar-based products, so check your state wildlife agency's rules before using anything beyond a standing planted crop .

How do I put all this together for my own field

Start with the soil test. It's the cheapest, highest-leverage step in the entire process, and skipping it means you're fertilizing blind. Contact your county extension office (most land-grant universities run a soil testing lab) and expect to pay somewhere in the $10-20 range per sample, with results back in one to three weeks depending on the season and lab volume ^[3]. Once you have pH and nutrient levels back, match your seed choice and fertilizer rate to the actual recommendation, not a generic chart. If your test says you need 40 lbs of P2O5 and 60 lbs of K2O per acre, buy a blend that gets you there rather than defaulting to a bag of 19-19-19 because that's what the farm store had on the shelf. If you'd rather skip building the plan yourself, this is exactly the gap a $99 one-time Custom Food Plot Plan is built to fill: you send in your soil test results and location, and get back species and fertility guidance tailored to your zone and dirt, at /plot-plan-builder. It's general guidance built from your specific numbers, not a replacement for your soil lab's site-specific recommendation, but it takes the guesswork out of translating a test report into an actual seed and fertilizer shopping list. Whatever route you take, the sequence matters more than the brand of fertilizer: test soil, correct pH with lime if needed, match fertilizer to the crop and the test results, then plant in your zone's correct window. Skip a step and you're leaving yield, tonnage, and ultimately deer attraction on the table.

Frequently asked questions

How much fertilizer per acre does a clover food plot need?

Most clover plots do well with 200-300 lbs/acre of a low-nitrogen blend like 0-20-20, since clover fixes its own nitrogen from the air. Your soil test may show you need more or less phosphorus and potassium depending on existing soil levels. Maintenance years often need less than the initial establishment year.

Do deer eat sorghum?

Yes, deer eat sorghum, especially the grain heads once mature, and browse young shoots earlier in the season. It's more often used for drought tolerance and screening cover than as a top attraction crop, since clover, soybeans, and brassicas typically pull deer more consistently in mixed plantings.

Do deer eat clover, and do they like it?

Yes, clover is one of the most preferred and widely planted food plot forages, often testing at 20-30% crude protein. It stays palatable through much of the growing season and, as a perennial, can produce for 3-5 years before replanting, according to Mississippi State University Extension food plot guidance.

When should I plant food plots for deer?

Fall plots (brassicas, cereal grains, clover) generally go in mid-July through early September, timed for 60-90 days before first hard frost. Spring plots (soybeans, cowpeas, summer clover) go in after your last frost date, which ranges from late April in the South to early June in northern states.

When do you plant oats for deer food plots?

Oats typically go in 6 to 10 weeks before the first expected hard frost, roughly early August in the northern whitetail range to mid-September in parts of the South. They germinate quickly, often in 5-7 days, and are commonly blended with winter wheat or rye for longer green growth into winter.

When do you plant turnips for deer?

Turnips need about 80-90 days before first hard frost to size up properly, so most plots go in mid-July (northern states) through early September (Deep South). Frost actually improves palatability by converting starches to sugars, which is why deer often hit turnip plots harder after the first freeze.

What is a food plot?

A food plot is a planted area, usually a quarter acre to several acres, established specifically to provide supplemental deer forage, distinct from crop fields grown for harvest and sale. Common species include clover, brassicas, cereal grains, and soybeans, chosen for palatability and nutrition rather than market yield.

What is deer's favorite food?

There's no single universal favorite; preference shifts by season and region. Acorns are often a top preferred food in fall where available, soybeans and forbs draw deer in summer, and brassicas or cereal grains become primary draws in late fall and winter as energy needs rise.

Do deer like honey?

There's no real evidence deer specifically seek out honey, and it isn't part of natural whitetail diet or a recognized food plot or attractant strategy. Many states also restrict baiting or feeding with additives like sugar products, so check your state wildlife agency's rules before trying anything beyond a standing planted crop.

How much does a soil test cost for a food plot?

Basic soil tests through university extension labs typically run $9 to $20 per sample depending on the state and how many nutrients are tested. Results usually come back within one to three weeks, and the report gives you actual lbs/acre fertilizer recommendations rather than a generic starting rate.

Do I need lime as well as fertilizer for a food plot?

Often yes. If soil pH is below about 6.0, plants can't fully access phosphorus and potassium even if you've applied plenty. Clover in particular wants pH 6.0-7.0. Many first-time plot fields need 1-2 tons of ag lime per acre, applied months ahead of planting since lime reacts slowly.

What fertilizer blend is best for brassicas like turnips?

A complete blend like 19-19-19 or 13-13-13 at 300-400 lbs/acre is a common starting rate for brassicas, often followed by a nitrogen topdress 4-6 weeks after planting. Brassicas are heavier nitrogen and boron feeders than many food plot species, so a soil test matters more here than for clover.
