This publication is intended to provide a starting point for farmers who are new to growing cover crops. With experience, farmers may fine-tune the use of cover crops for their systems.

Introduction

This publication provides an introductory approach to integrating cover crops following corn silage and before corn or soybeans. These cover crops can have many benefits, such as erosion control, weed suppression, improved soil health, and quality forage production.

Planning and Preparation
  • Planning—Start planning early. Educate yourself by talking to experienced cover crop users, attending conferences and field days, and reading as much as possible about cover crops. Start small and determine your purpose and objectives for using cover crops. If needed, arrange for equipment, additional labor, or custom operators.
  • Corn hybrid and planting—Plant the corn silage crop early and use a hybrid within the adapted maturity range for your location. This will allow you to plant your cover crop earlier and increase fall growth.
  • Residual corn herbicides—Consult your agricultural supplier regarding residual corn herbicides that could cause concerns for newly planted cover crops. Cereal grains (rye, oats, and wheat) are not affected by most pre-emergence residual herbicides but are somewhat affected by post-emergence herbicides. If using rapeseed in your mix, it may be sensitive to carryover from herbicides. If cover crops will be grazed, additional herbicide restrictions may apply.
  • Seed purchase—Order your seed early from a reputable seed supplier to ensure a good germination rate, purity of seed, and that all seed has a seed analysis tag. Specific varieties of cereal rye, wheat, or oats may produce significantly more growth, but they are also more expensive than variety not stated (VNS) seed.
Fall Work
  • Corn silage harvest—Harvest fields where a cover crop is to be planted first, if possible.
  • Tillage or no-tillage—No-till drilling into corn silage stubble is usually the best strategy to use unless tillage is necessary to incorporate manure, fertilizer, or lime, or needed to smooth out the seedbed, such as deep wheel tracks after corn silage harvest. The tillage should be completed as soon as possible and before seeding the cover crop.
  • Timing of planting—Ideally, plant your cover crop as soon as possible after silage harvest. Plant the oats cover crop mix or oats alone by Sept. 7. Oats will not grow enough to justify their use after this date. For winter wheat only, plant before 50% frost date. For rye only, plant before two weeks after the 50% frost date. In northern Nebraska, this would be before Oct.15; in southern Nebraska, before Nov. 1. Use the Cover Crop Selector Tool (in the Resources section) for more precise dates for your county. These dates are guidelines; the sooner these cover crops are planted in the fall, the better.
  • Seeding rate for a mix—Drilled: oats, 20 lbs./acre; wheat, triticale, or rye, 25 lbs./acre; rapeseed, 1 lb./acre. Broadcast: oats, 25 lbs./acre; wheat, triticale, or rye, 30 lbs./acre; rapeseed, 2 lbs./acre.
  • Seeding rate for oats alone—Drilled: 30–40 lbs./acre; if grazed, 40–55 lbs./acre.
  • Seeding rate for wheat or rye alone—25–35 lbs./acre; if grazed, 45–60 lbs./acre. Shallow incorporation: oats, 45–60 lbs./acre; wheat, 50–65 lbs./acre; rye, 50–65 lbs./acre.
  • Planting method—If you include the brassica rapeseed, seeding depth is limited as these are small seeds. A depth of 0.50 inch is best. If you have a drill with two boxes, you can dribble the rapeseed on top of the ground and then drill your cereal grain to a depth of 0.75–1.50 inches.

Spring Work
  • Termination timing—Oats and rapeseed will usually winter-kill. Terminate the wheat, triticale, or cereal rye in the spring when plants are 6–12 inches tall and actively growing or about two weeks before planting corn or soybeans—whichever comes first. Many experienced growers will terminate wheat, triticale, or cereal rye the same day as planting corn or soybean, or within one week, particularly in irrigated situations. This provides an extra benefit for weed control. Risk of wheat stem maggot damage to corn seedlings increases when corn is planted into a green, non-terminated, winter cereal grain cover crop. Another concern is that cover crop residue with a high carbon-to-N (C:N) ratio can reduce soil-available N. Starter N fertilizer is recommended at planting or sidedress as soon as possible to offset this early immobilization when the corn has a high N demand. New cover crop users should terminate earlier when the cereal crops are smaller for corn. Planting green into soybeans is much less risky and could be implemented by new cover crop users.
  • Termination herbicide—Wheat, triticale, and cereal rye can typically be terminated with a full rate of glyphosate (1 lb. acid equivalent/acre) after these crops begin growing in the spring. Effectiveness and rapidity of termination improve if winter cereal grain grows rapidly and air temperatures are warmer.
  • Termination modifications for dry weather—Watch the weather and be ready to modify your termination plans. In a dry spring, cereal grain crops have the potential to use moisture that the cash crop will need, so terminate cover crops sooner to allow rainfall to make up the deficit.
  • Termination modifications for wet weather—In a wet spring, be ready to take advantage of any break in the weather and/or use low axle weight sprayers.
  • Option to harvest cereal rye, wheat, or triticale as a silage crop—A cereal grain cover crop planted in the fall and harvested at boot stage can provide a substantial amount of good quality forage. Waiting for the cereal grain cover crop to reach the boot stage (mid-May to early June) will delay planting of the next corn or soybean crop. If this crop is to be insured, then the small-grain cover crop should be terminated and corn or soybeans planted before the crop insurance late-planting deadline.
  • Corn or soybean planting—Almost all modern planters and drills are fully capable of planting corn or soybeans into a clean, small-grain cover crop. Planter adjustments are usually needed to ensure correct planting depth and seed furrow closure.
  • Scouting after planting—Scout for corn or soybean emergence, population, and insect pests (e.g., wheat stem maggot in corn). Scout for weeds because substantial small-grain residue, especially cereal rye, can delay emergence of annual weeds, which may then delay the need for and timing of applying post-emergence herbicides.

Introduction

This publication provides an introductory approach to integrating cover crops following wheat and before corn or soybeans. These cover crops can have many benefits, such as erosion control, improved soil health, weed suppression, and quality forage production.

Planning and Preparation
  • Planning—Start planning early. Educate yourself by talking to experienced cover crop users, attending conferences and field days, and reading as much as possible about cover crops. Start small and determine your purpose and objectives for using cover crops. If needed, arrange for equipment, additional labor, or custom operators.
  • Residual herbicides—Consult your agricultural supplier regarding residual wheat herbicides that could cause concerns for newly planted cover crops. If cover crops will be grazed, additional herbicide restrictions may apply.
  • Seed purchase—Order your seed early from a reputable seed supplier to ensure a good germination rate, purity of seed, and that all seed has a seed analysis tag.
Summer Work
  • Dryland vs. irrigation—Irrigation allows for flexibility in managing planting dates and provides some insurance against dry planting conditions. Dryland seedings should occur immediately following wheat harvest in July for warm- and cool-season mixes. If delayed until August, consider changing to a cool-season mix. Contact your local Extension personnel for more information.
  • Residue management—Uniform spreading of chaff and straw is essential during wheat harvest in order to avoid interfering with the cover crop seeding operation.
  • Nitrogen management—If growing a forage crop, a nitrogen application before seeding a cover crop may be beneficial to counteract tie-up caused by stubble. Consider taking soil samples after the wheat harvest to determine nitrate-nitrogen levels. Depending on the prior nitrogen management, wheat yield, and weather, some residual nitrogen should be accounted for. The addition of nitrogen (up to 50 lbs. N/acre) may be beneficial in increasing biomass production of many of the cover crops, e.g., forage sorghum, sorghum-sudangrass.
  • Wheat curl mite—Volunteer winter wheat and some species in diverse cover crop mixes planted after wheat (e.g., sorghums, millets, oats, barley) can serve as a host for wheat curl mites. These mites are vectors for the wheat streak mosaic virus complex. Planting new winter wheat fields within two miles of this existing field may lead to yield losses in winter wheat fields. Applying a burndown herbicide before planting the cover crop may be an option to control volunteer wheat and reduce competition from weeds. Please read the herbicide label and consult with an agricultural supplier or local Extension personnel for more information.
  • Planting cover crop—No-till drill into stubble at least 45–60 days before the 50% frost date for your area. For most of Nebraska, this mix will need to be planted before early September. Use the Cover Crop Selector Tool (in Resources section) for more precise dates for your county. For the highest cover crop productivity, seed immediately after wheat harvest. Seeding depth is limited by the brassica species in the mix (rapeseed) as these are small seeds. A depth of 0.50 inch is best.
  • Seeding rate—Oats are used in most diversified mixes because they are an excellent carrier for the other seeds. Seeding rates per acre are: 16–24 lbs. of oats, 4 lbs. of forage sorghum or sorghum-sudangrass, 2 lbs. of pearl millet, 1 lb. of grain sorghum, 1 lb. of rapeseed, and 4 lbs. of buckwheat.
Figure 1: This diversified cover crop mix seeded right after wheat harvest was able to catch a 2-in rain and got off to a good start (Gary Lesoing)
Spring Work
  • Winterkill—All species in the mixture will usually winter-kill with the onset of hard freezes, which will eliminate the need for any changes to spring management.
  • Cover crop termination—If you have something in the mix that overwinters or germinates and emerges in the spring, the general recommendation is to terminate the mixture approximately two weeks prior to planting the next cash crop. Termination can be achieved using a full rate of glyphosate.

Introduction

The following recipe provides an introductory approach to integrating a cover crop into a wheat rotation with soybean or corn. Planting oat and daikon-type radish cover crops after wheat (see Figure 1) and ahead of a soybean or corn cash crop is an easy way to introduce cover crops into your rotation because these cover crops both winter-kill and add important diversity to agricultural fields.

Planning and Preparation
  • Planning—Educate yourself. Start small. Be timely. Prioritize management based on your purpose and objectives.
  • Wheat variety and planting—No modifications to wheat variety and planting are required for the successful use of cover crops after wheat harvest.
  • Residual wheat herbicides—Oats and radish are tolerant of most herbicides applied to the wheat crop in-season before flag leaf emergence. However, if the cover crop will be grazed or fed to livestock, there may be restrictions on herbicide use. See herbicide label for specific instructions.
  • Seed purchase—Order cover crop seed early from a reputable seed dealer. Purchasing named varieties is preferred to buying variety not stated (VNS) seed. Important traits such as vegetative growth rate, cold and heat tolerance, disease resistance, or insect resistance of named varieties are known, whereas little is known about those traits with VNS seed. A general goal for a mix planted at this time is for it to remain vegetative and growing biomass late into fall or until it is terminated by freezing temperatures. For cover crop radishes (daikon-type), be sure to purchase a single variety since mixed varieties may have unpredictable emergence or bolt to flower immediately and produce seed rather than producing the desired large amounts of biomass and roots. Purchasing VNS oat seed will be less of a risk when obtaining it from a reputable dealer if it has been cleaned, tested for germination, and has a seed tag.
Summer/Fall Work
  • Wheat harvest—Harvest wheat at the normal time in fields where a mix of oats and radish will be planted. If residue levels are high, consider removing straw. If straw is not harvested, cut the wheat high or use a stripper header and make sure that the combine distributes straw and chaff evenly across the swath.
  • Planting time—Plant oats and radish anytime in August after wheat harvest and after any other field activities such as manure application or tile installation. Planting a cool-season annual, such as radish, prior to August is not recommended as it may result in flowering and seed production instead of quick coverage and biomass accumulation, which is the desired goal for this cover crop. Use the Cover Crop Selector Tool for precise seeding dates for your county.
  • Planting method—Drill or plant radish and oats in narrow rows to a depth of 0.50–1.00 inch, depending on moisture, or broadcast with light incorporation. Note that disturbance of the soil, if any, should be light since excessive disturbance of wheat stubble may reduce cover crop benefits. Light tillage will likely synchronize volunteer wheat and cover crop emergence. Emerged winter wheat will overwinter and need to be terminated before corn or soybean seeding occurs the following spring.
  • Seeding rate in oats/radish mix—Mix seeds prior to planting at the following rates (pure live seed, drilled or broadcast): oats, 18–36 lbs./acre; radish, 1–2 lbs./acre. Adjustments to your mix ratio can be made to customize to your specific situation. A higher rate of oats and lower rate of radish is recommended for highly erodible soils and areas sensitive to phosphorus loss. When radishes winter-kill, they will make the soil more erodible and release phosphorus. If you are planning to plant corn in the spring, a higher rate of radish as compared to oats is advised to lower the carbon-to-nitrogen (C:N) ratio of the residue.
  • Tillage or no-tillage—Under most circumstances, it is easy for no-till planters to achieve excellent seed placement in the winter-terminated residues. If tillage is used, it is usually better to wait until spring in order to maintain surface cover to prevent erosion.
  • Fertility or liming—If applying P, K, lime, or manure, complete the application, injection, and/or incorporation prior to seeding or apply to the growing oats and radish before the ground freezes. It is not advised to apply manure at seeding as high salt levels can result in poor germination. If injecting manure, low-disturbance injectors are available that will minimize damage to oats and radish. Surface application of liquid manure on top of the cover crop is not recommended. Surface broadcast of dry manure or litter should be done prior to seeding, but 4 tons or less can be applied to growing oats and radish with minimal damage provided it is evenly distributed.
Figure 1: A growing oats/radish mix (Eileen Kladivko)
Spring Work
  • Starter fertilizer—No modifications to your typical fertilization program are required for planting soybean or corn after oats and radish use.
  • Termination—Oats and radish should both terminate by winterkill. However, mild winters and good snow cover sometimes allow radish to overwinter. If this occurs, radishes are easily terminated with typical pre-plant herbicide applications.
  • Soybean or corn planting—It is usually best to no-till plant cash crops into the dead/dry or standing cover crop. Almost all modern planters and drills are fully capable of planting soybean or corn into an oat and radish cover crop. In some cases, the radish tuber will swell enough to cause soil heaving and/or leave holes following the desiccation of the tuber. By cash-crop planting time, this is seldom a no-till planting issue, particularly if the planter is equipped with row cleaners. Check planter attachments and settings such as row cleaners, closing wheels, and down pressure shortly after beginning to plant into the cover crop residue as some adjustments are usually needed for uniform seed depth, seed furrow closure, and ultimately, seedling emergence.
  • Scouting—After soybean or corn planting, scout for crop emergence and population. Additionally, scout for weeds since cover crop residue can often delay emergence of annual weeds, which may delay the application of post-emergence herbicides.

This publication is intended to provide a starting point for farmers who are new to growing cover crops. With experience, farmers may fine-tune the use of cover crops for their systems.

Introduction

The following recipe provides an introductory approach to integrating a cover crop into a wheat-based rotation with soybean or corn. Planting a cover crop blend that predominantly consists of cool-season species and is winter-killed adds diversity and provides soil armor through summer and spring. However, in some situations added ground cover in the spring in combination with excess soil moisture could be a problem unless winter cereals (winter rye, wheat, or triticale) are included in the mix.

Planning and Preparation
  • Planning—Consult with university Extension staff, local NRCS staff, and experienced producers to gain insight on the practice. Start small while exploring new practices. In South Dakota, timeliness is important due to the shorter growing window. Always focus on your objectives, such as whether you are growing the cover crop for ground cover, fall grazing, nutrient cycling, etc.
  • Small-grain variety and planting—Small-grain varieties such as wheat or oats do not need to be changed or modified to incorporate cover crops following grain harvest or haying. Planting small grains early in the spring is important for good growth and development, which also typically results in earlier harvest and allows more time for cover crops to grow before a frost.
  • Residual herbicides—A blend consisting primarily of cool-season cover crops such as cereal grains (oat, barley), brassicas (radish, turnip, rapeseed), and legumes (field pea), and some warm-season grasses such as millet and sorghum-sudangrass have shown good tolerance to commonly used herbicides. If the cover crop is intended for grazing in the fall/winter, it is critical to follow grazing restrictions stated on the herbicide label.
  • Seed source—Planning ahead and ordering seed early with the objective in mind is important. Most cover crop seed dealers have their own pre-mixed blends but are willing to custom-mix upon request. Follow the seed label and review the individual species to make sure that the growth habit of each is ideal for the planting time. If opting for a mix of only one or two species, labeled varieties usually perform better than variety not stated (VNS) seeds.
Summer/Fall Work
  • Harvest—Harvest wheat/oats at the normal time. If weed pressure is high, you can spray glyphosate or other herbicides with the least residual effects. Herbicides are a better option than tillage as stirring the soil can dry it out and reduce germination. Baling small-grain residue is common in South Dakota but can make establishment of the cover crop difficult where the windrows were present.
  • Timing of planting—In South Dakota, wheat and/or oats are generally harvested from the second week of July to the first week of August. Planting cover crops immediately following harvest is recommended so that the seasonal window can be maximized. A mix consisting mostly of cool-season annual species grows well as temperatures start to gradually decrease. Use the Cover Crop Selector Tool (in Resources section) for precise seeding dates.
  • Planting method—Determining seeding depth is tricky when planting a mix with various seed sizes. Drilling to a moderate depth of 0.50–0.75 inch will be good for most mixes. Tilling or soil disturbance is not recommended as this may cause unwanted weed growth.
  • Cover crop types—Diversity of species in a mix is good and typically will provide the best benefits. The general rule of thumb is to select cover crops that are of contrasting growth habit to the subsequent cash crop. For example, if the next season’s cash crop is corn, planting cover crop blends that have a higher proportion of cool-season broadleaves is suggested; if the next season’s crop is soybean, then a mix with more cool-season grasses would be ideal. If wheat or other small grains are to be raised for seed purposes, cover crop blends that contain winter cereals (e.g., winter wheat, winter rye, winter triticale) are not suggested.
  • Seeding rate—Seed size and proportion in the mix determines the seeding rates. For example, a mix high in large-seed species such as peas and oats can be higher than the ones dominant in brassicas. Typically, the seeding rate of commonly marketed cover crop mixes can range from 15 to 30 lbs./acre. The full seeding rate of individual species can be found in Cover Crop: Common Species and Properties of South Dakota (see Resources).
  • Tillage—Tillage or soil disturbance is not suggested.
  • Fertility—Fertilizer is not usually required for a cover crop mix with well-balanced species. However, producers who have livestock and intend to maximize growth for fall/winter grazing have shown interest in using low rates of fertilizer. Although there are no specific guidelines on fertilizer rates for various cover crop blends, using nitrogen rates in the range of 30–40 lbs. N/acre can enhance cover crop growth and establishment, especially following high-yielding wheat crops.
  • Grazing—Producers who prefer to grow cover crops after small grains for grazing in the fall/winter can slightly increase the proportion of cool-season grass species such as oats and barley. Include at least 60% grasses in the mix for grazing. To assist in calculating the amount of grazing your cover crop can offer, refer to the Grazing Cover Crop Calculation App (in Resources).
Figure 1: Frost-killed cover crops seeded after oats in southeast South Dakota (Peter Sexton)
Spring Work
  • Starter fertilizer—No modifications to your typical fertilization program are required for planting soybean or corn. However, there are a few considerations for planting corn. After a cover crop has winter-killed, get a current soil test to look at nitrates and sulfur. Cover crops can sequester nitrogen, which is a desired attribute to reduce leaching or runoff. But mixes with a high proportion of Brassica species (radish, turnip, rapeseed) can use quite a bit of sulfur. Soil-testing and applying these nutrients as needed to minimize the chance of nutrient deficiency is a good practice.
  • Termination—Typical cover crop blends should winter-kill in South Dakota. However, mild winters can leave a few plants the next spring. Timely scouting and herbicide application as needed is suggested for uniform control of cover crop plants that survived the winter. Some mixes with winter annuals such as winter triticale, cereal rye, or winter camelina will require spring termination.
  • Soybean or corn planting—It is usually best to no-till plant cash crops into the dead/dry or standing cover crop. Almost all modern planters and drills are fully capable of planting soybean or corn into terminated cover crop residue. Check planting depth and seed furrow closure shortly after beginning.
  • Scouting—After planting soybean or corn, scout for crop emergence and population. Additionally, scout for weeds since cover crop residue can often delay emergence of annual weeds, which may delay the application of post-emergence herbicides.

Introduction

This recipe provides an introductory approach to integrating a cover crop mix of oats and radish after an early harvested processing vegetable, such as snap beans, cucumbers, peas, or early tomatoes. Both oat and radish can successfully establish in late summer to early fall and usually winter-kill. It is a low-risk mix that will help control tough perennial or winter annual weeds, minimize erosion, build soil structure, reduce compaction, and add some extra diversity to your rotation.

Planning and Preparation
  • Planning—Keep it simple. Start small on one field. Be timely. Prioritize cover crop management based on your goals. Fine-tune the recipe for your needs over time. If cole or other Brassica crops are grown in the rotation, it’s best to use peas instead of radish in order to avoid a buildup of pest pressures.
  • Vegetable planting—No modifications to the crop are required for the successful use of cover crops.
  • Residual herbicides—Oats and radish are tolerant of most herbicides applied to the vegetable crop in-season.
  • Seed purchase—Seed supplies and prices can vary depending on the time of year; it is good practice to order seed early (before harvest). The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has compiled a list of reputable cover crop seed suppliers (see Resources).
  • Fertility or manure—Fall fertilizer incorporation can damage the living cover crop. Plan for fertilizer or manure application before planting the cover crop or after the cover crop winter-kills, or use a low-disturbance injection method to minimize damage.
Summer/Fall Work
  • Vegetable harvest—Ensure that crop residues are spread evenly. Some light tillage can help with residue breakdown under the cover crop canopy. If the field was heavily tracked or rutted during harvest, level the field with tillage. For early harvested vegetables, such as peas, waiting a few weeks may allow for breakdown of crop residues and improve the seedbed for the cover crop.
  • Timing of planting—Plant the oat-radish mix between mid-August and mid-September. Planting radish prior to August is not recommended as it will often result in flowering and seed production instead of quick coverage and biomass accumulation.
  • Seeding rate in oats/radish mix—Mix seeds prior to planting. For oat, use 30–60 lbs/acre. Use the higher end of that range if manure application and/or erosion control are your goals; the lower end of that range should be sufficient if you want to build soil structure or have land covered. Radish should be seeded at no more than 2 lbs/acre if drilling and 2–3 lbs/acre if broadcasting.
  • Planting method—An oat-radish cover crop can be planted with a drill at a depth of 0.50–0.75 inch or broadcast with light incorporation. An oat-radish cover crop can also be mixed with dry fertilizer, applied with a spreader, and then lightly incorporated.
  • Fertility or liming—After most processing vegetables, extra nitrogen (manure or fertilizer) is not required. Use a current soil test (no older than four years) to determine lime or phosphorus and potassium nutrient requirements for the next year’s crop. Fertilizers can be applied at the same time as seeding to reduce costs. Lime should be applied separately as it will need to be incorporated deeper than the cover crop seed.
  • Manure—Up to 4 tonnes/acre of solid manure or litter can be surface-broadcast to growing oats and radish provided it is evenly distributed; otherwise it should be done prior to seeding. If injecting manure, low-disturbance injectors are available that will minimize damage to oats and radish. See Use and Management of Manure and Other Organic and/or Prescribed Materials in Resources for more information about recommended practices in Ontario.
  • Tillage or no-tillage—The cover crop can be established with no tillage, but light tillage can help suppress weeds to allow the cover crop to get established. Fall full-width tillage is not necessary and minimizes the benefits of soil cover over the winter.
Figure 1. This shows a well-established oat-radish mix. Radish is very competitive; do not use more than 2 lbs/acre if drilling and 2-3 lbs/acre if broadcasting in a mix with oats. (OMAFRA)
Spring Work
  • Fertilizer—No modifications to a typical fertilization program are required after an oat-radish cover crop mix.
  • Termination—Both oats and radish should winter-kill. However, mild winters and good snow cover sometimes allow overwintering of radish. If this occurs, it is easily terminated with a typical pre-plant herbicide application for broadleaf weeds.
  • Direct-seeding—Most modern planters are fully capable of planting corn, soybean, or vegetables into the expected low spring-residue cover from an oat-radish mix. But if direct-sowing vegetables, consider strip or zone tillage to prepare the seedbed. Check planting depth and seed furrow closure shortly after beginning to plant as some adjustments may be needed.
  • Transplanting—Scout fields early and adjust timing of operations accordingly. An oat-radish cover crop reduces winter annuals, such as chickweed, so tillage for weed control may not be necessary. Cover crop residues can slow the early spring drying and warming of the soil, particularly for early crops such as cole crops; it is unlikely to affect warm-season crops such as tomatoes.
  • Scouting—After planting, scout for crop emergence and population. Additionally, scout for weeds since cover crop residue on the soil surface can delay the emergence of annual weeds, which may delay the application of post-emergence herbicides.

This publication is intended to provide a starting point for farmers who are new to growing cover crops. With experience, many farmers fine-tune the use of cover crops for their systems.

Introduction

This recipe provides an introductory approach to integrating a cover crop mix of oats and radish after wheat harvest going to corn or soybean the next year. Since both oat and radish can be sown after wheat harvest and usually winter-kill, it is a low-risk mix that will help control tough perennial weeds, minimize erosion, build soil structure, reduce compaction, and add some extra diversity to your rotation.

Planning and Preparation
  • Planning—Keep it simple. Start small on one field. Be timely. Prioritize cover crop management based on your goals. Fine-tune the recipe for your needs over time.
  • Wheat variety and planting—No modifications to wheat crop are required for the successful use of cover crops after wheat harvest.
  • Residual wheat herbicides—Oats and radish are tolerant of most herbicides applied to the wheat crop in-season before flag leaf emergence.
  • Seed purchase—Seed supplies and prices can vary depending on the time of year; it is good practice to order seed early (before wheat harvest). The ­Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has compiled a list of reputable cover crop seed suppliers (see Resources).
Summer/Fall Work
  • Wheat harvest—Ensure that straw and chaff are spread evenly. If residue levels are high or variable, consider removing the straw or using light tillage to improve seed-to-soil contact for the cover crop. However, light tillage will tend to synchronize volunteer wheat and cover crop emergence. Weeds can be sprayed after wheat harvest but before cover crop emergence.
  • Timing of planting—Plant the oat-radish mix up to late August after wheat harvest. Planting radish prior to August is not recommended as it may result in flowering and seed production instead of quick coverage and biomass accumulation.
  • Planting method—An oat-radish cover crop can be drilled at a depth of 0.50–0.75 inch or broadcast with light incorporation. If broadcasting, adjust to a half lap for spinner spreaders or use an airflow spreader to ensure even distribution of seeds. An oat-radish cover crop can be mixed and applied with P and K fertilizer for the following corn or soybean crop, and then lightly incorporated.
  • Seeding rate of oat and radish—Mix seeds prior to planting. For oat, use 30–60 lbs/acre. Use the higher end of that range if manure application and/or erosion control are your goals; use the lower end of that range if you are hoping to build soil structure or have land covered. Radish should be seeded at no more than 2 lbs/acre if drilling and 2–3 lbs/acre if broadcasting.
  • Tillage or no-tillage—Full-width tillage is not necessary and minimizes the benefits of soil cover over the winter. By the spring, there is typically very little residue (Figure 1).
  • Fertility or liming—Use a current soil test (no older than four years) to determine lime or nutrient requirements for the next year’s crop. Lime and fertilizers can be applied at the same time as seeding to reduce costs. Lime will need to be incorporated more deeply.
  • Manure—Up to 4 tonnes/acre of solid manure or litter can be surface-broadcast to growing oats and radish provided it is evenly distributed; otherwise it should be done prior to seeding. If injecting manure, low-disturbance injectors are available that will minimize damage to oats and radish. See Use and Management of Manure and Other Organic and/or Prescribed Materials in Resources for more information about recommended practices in Ontario.

Spring Work
  • Fertilizer—No modifications to a typical fertilizer program are required for planting corn or soybeans after an oat-radish cover crop mix.
  • Termination—Both oats and radish should winter-kill. However, mild winters and good snow cover sometimes allow overwintering of radish. If this occurs, it is easily terminated with typical pre-plant herbicide application for broadleaf weeds. Volunteer winter wheat may also be present and require termination.
  • Corn or soybean planting—It is usually best to no-till cash crops into the dead/dry or standing oat-radish residue. Almost all modern planters and drills are fully capable of planting corn into the expected low residues from an oat-radish mix. If there is a lot of residue, soils may be slower to dry and warm, which may delay planting. Check planting depth and seed furrow closure shortly after beginning to plant into the cover crop residue (Figure 1) as some adjustments may be needed. Based on scouting and field history, consider using treated seed to control insects and diseases, but oat-radish mix is not expected to increase pest pressure.
  • Scouting—After corn or soybean planting, scout for crop emergence and population. Additionally, scout for weeds since cover crop residue can delay the emergence of annual weeds, which may delay the application of any contact post-emergence herbicides.

Midwest Cover Crops Council (MCCC-126)


This publication is intended to provide a starting point for farmers who are new to growing cover crops. With experience, farmers may fine-tune the use of cover crops for their systems.

Introduction

A canning or processing crop such as green bean, sweet corn, or pea is harvested early or by midsummer and offers an excellent window to get adequate cover crop growth before any following crop. Cover crops following canning crops will protect soil from erosion and improve soil structure after heavy harvesting equipment is used to take off the canning crop. Some canning crops leave significant residual nitrogen (N) in the soil that is vulnerable to leaching, and a cover crop can retain that soil N for future crops. Since growers follow canning crops with any number of different rotations, a fast-growing species such as oats mixed with a light seeding of radish is a safe choice as both will winter-kill. With this combination, no spring termination is needed, and there is little chance of tying up N for the following year.

Planning and Preparation
  • Planning—Educate yourself. Go to field days, learn from farmers who are currently planting cover crops, read about cover crops, check out cover crop research results from local universities, and work with your local Natural Resources Conservation Service (NRCS) and Soil and Water Conservation District (SWCD). Identify your goals in planting a cover crop as these will drive many decisions. Start small, and choose a field that has low weed pressure to create the best conditions for success. Consult with your crop insurance representative to ensure planned practices will not affect your insurance coverage.
  • Canning crop management—Follow best management practices regarding fertility and weed management, and make sure to notify the canning company that you’re planning on a cover crop after a canning crop harvest.
  • Residual herbicides—Commonly used herbicides can negatively impact cover crop establishment, so check the history of herbicide application for your field. Oats can tolerate many preemergence and postemergence herbicides. However, if the oats/radish biomass is to be grazed or used for feed or forage, you must follow the rotational crop restrictions listed on the label of any applied herbicides. Rotational restrictions should be checked for herbicides used in the current and previous cropping season if the cover crop is to be grazed or used for feed or forage. (See Using Herbicides and Cover Crops in Corn and Soybean in Resources.)
  • Seed purchase—Order cover crop seed early from a reputable source. If you grow your own, get it tested for germination, purity, and weed seed. Named varieties can produce more growth and have more predictable development, but they are usually more expensive than VNS (variety not stated) seed. Use good quality seed that has been cleaned and tested for germination and weed seed contamination. Utilize local sources of seed as much as possible to help prevent the introduction of invasive noxious weeds such as Palmer amaranth.
  • Fertility or manure—Fall fertilizer incorporation could damage the cover crop and destroy any structure gained, so plan to apply any needed fertility after the cover crop has winter-killed. If manure will be applied in the fall, use low-disturbance injectors to minimize damage to the cover crop.
Summer/Fall Field Work
  • Timing of cover crop planting—After canning crop harvest, some light tillage may be necessary to create a seedbed for the cover crop. Using a leveling tool such as a vertical tillage bar with an air seeder on top allows for tilling and seeding the cover crop at the same time. Try to time seeding when rain is in the forecast, or if you use irrigation, you can water in the seed for reliable establishment.
  • Planting method—Drill the seed to a depth of 0.75 inch, or broadcast the seed with a shallow incorporation to less than 1 inch to allow for good seed-to-soil contact and enhanced establishment.
  • Seeding rate—For oats, a minimum seeding rate of 21 lbs./acre of pure live seed (PLS) is suggested when seed is drilled or incorporated. The seeding rate should be increased to a minimum of 45 lbs./acre of PLS if broadcast. For radish, the rate is 1.2 lbs./acre if drilled or incorporated, and 1.7 lbs./acre if broadcast. These rates are based on a mixture of 70% oats–30% radish. If another ratio is desired, rates should be adjusted using the Minnesota Cover Crop Design Tool (see Resources).
  • Tillage—No fall tillage is needed. The oat/radish residue will freeze, then decompose over the winter, and a cash crop such as field corn or soybeans can be no-tilled into the residue if you wish. While full-width tillage may be used in the spring, this will reduce soil structural improvements the cover crop provided over the winter.
  • Future considerations—An oat/radish mixture is promoted here as the entry-level cover crop mixture post-canning crop. In future years, you may consider grasses that survive the winter (e.g., winter rye or triticale) for spring erosion control or legumes (e.g., crimson clover, which winter-kills, or red clover, which survives the winter) to supply N to the next cash crop. However, both of these options will have separate considerations and management recommendations. Use the Cover Crop Selector Tool (see Resources), or visit with local representatives of NRCS or Extension for more specific information on seeding other species.

Spring Work
  • Scouting—In the spring, scout the remaining cover crop residue, and note whether any oat seed that remained dormant over the winter begins to sprout in the spring. Any grass-target herbicide should take care of these escapes.
  • Cash crop planting—Most modern row planters are fully capable of planting corn or soybeans into residue from a dead oat/radish cover crop. Row cleaner attachments may be beneficial. Check planting depth and seed furrow closure shortly after beginning to plant in case any planter adjustments are needed, such as increasing down pressure to move through increased residue.
  • Scouting after planting—After planting, scout for emergence and population as well any insect, disease, or weed pressure.
