Whether you are farming conventionally or abide by no-till or organic practices, soils should have a living crop growing on each field for as many months as possible. Many of our forage crops also act as cover crops. In addition to selling forages that can double as cover crops, Southeast AgriSeeds has developed several mixtures that will help improve your soil’s health. Mixtures are far more beneficial in improving the life of your soil than a monoculture. Tap into cover crops’ huge potential to improve your farm’s long term productivity and profitability. Consult with our agronomists to choose the appropriate cover crop for your farm.

For best root nodulation, nitrogen fixation, and growth, inoculate legume seed and seed mixtures containing legumes with the appropriate inoculant, as indicated.

Cover Crop Cocktails/Mixtures

3-Way Clover

A red, ladino, and sweet clover mix that can be frost seeded, spring seeded, fall seeded, aerial seeded, broadcast after last cultivation of corn, or seeded just before soybean leaf drop. With its diversity, the white and red clover will grow in long, cool springs and in the fall, and the yellow blossom sweet clover grows well in the summer months and drier spells. Can work as a perennial pollinator mix; recommended for two years at the most. Can also be used for wildlife food plots. Recommended seeding rate: 10-15 lbs/A.

3-Way Clover is pre-inoculated with Rhizobium bacteria for best nitrogen fixation.

Boost Extend

A radish, Cosaque Winter Oats, and triticale mix for extended cover, organic matter production, and N scavenging. Wheat and cereal rye finish their life cycle fairly early in the season, leaving behind several weeks to more than a month of no nutrient uptake. The addition of triticale and a true winter oat will extend that growth season, providing that heavy mat that is so critical for building soil organic matter, keeping the soil cool during the heat of the summer, and holding moisture. Daikon radish will work to pull macro and micro nutrients from deep in the soil that the following crop needs to be aggressive. Recommended to use the season prior to a legume crop. Recommended seeding rate: 50 lb/A when paired with winter small grain.

Boost Extend Tech Sheet


A mixed legume and radish booster pack for combining with your favorite small grain. This blend is heavy in legumes (crimson clover, balansa clover, and Austrian winter pea) to create nitrogen for the upcoming cash crop, along with radish to mine nitrogen left from the previous season. The radish will grow quickly in the fall, and winter kill after several days of 20 degree weather. This rotting root with then slowly release nutrients into the soil, creating organic matter and more efficient nutrient cycling. Terminate after legumes have begun to flower for the highest nitrogen production. The plant tissues will degrade slowly, releasing the nitrogen throughout the growing season. Recommended for use the season prior to heavy nitrogen users, such as corn or sorghum. Recommended seeding rate: 15 lb/A, paired with winter annual small grain.

Soy Supreme

Soybeans are not the most competitive plants, and this cover crop mix was designed with this in mind. Abruzzi rye, TriCal 815 Triticale, and the Cosaque Winter Oat provide aggressive growth from planting until termination, leaving behind a mat that weeds struggle to penetrate. Soybeans can fix their own nitrogen, so no legumes are necessary in this mix. The Daikon radish will aerate soil, address soil compaction issues, and make nutrients soybeans love available right in the root zone. Recommended seeding rate: 100 lb/A.

Cover Crop Individual Species

Annual Ryegrass

An inexpensive, quick growing annual utilized as a high quality forage crop or a cover crop. It can be overseeded into corn or soybeans or other vegetable crops. Ryegrass has an extensive root system that holds the soil in place, preventing erosion. It’s a very good nitrogen scavenger and grows organic matter deep into the soil with root biomass. The dense root system improves water infiltration and builds soil tilth. If mixed with legumes it establishes quickly and acts as a nurse crop, which improves early season weed control and helps the legumes over-winter. Recommended seeding rate: 15-20 lbs/A.

Cover Crop Radish 779

A cover crop radish variety with deep root growth. Cover Crop Radish 779 can be quite beneficial to row-crop farmers. The plants are able to capture excess nutrients left over from crops like corn and soybeans. As they grow over the fall months, they grow deep tap roots while covering the soil surface with their leafy topgrowth. The roots break up compaction and the surface coverage reduces weeds and erosion.

Cowpeas, ‘Iron Clay'

Productive heat tolerant vining summer-annual legume, excellent drought resistance, combined with good tolerance of heat, low fertility and a range of soils. If left to bloom it attracts many beneficial insects that prey on other pests. Slow to start, so it does well in mixes with other quicker growing species, especially those that are erect-growing that can serve as a trellis to support its growth. Works well as a forage, especially in a mix. Will not regrow consistently after cutting. Same as black-eyed peas (dry beans that can be used for human consumption). Recommended seeding rate: 40-60 lbs/A.

Inoculation with peanut inoculant typically recommended.

Crimson Clover

A legume cover crop that can be planted in late summer as a winter annual or in the spring. Rapid spring growth provides weed suppression and makes it a valuable spring and summer green manure, providing 60 to 100 lbs of N. It can be easily grown in rotation before grain sorghum or sorghum-sudangrass, and is also good for hay and grazing uses. In Northern areas of PA and farther north, crimson clover doesn’t over winter, but can be grown as a summer annual for fall nitrogen. Has a deep red flower that produces abundant nectar and is a habitat for beneficial insects and bumble bees. Great for mixtures (see our CARGO mix). Seed is larger than most other clovers, so use a higher seeding rate than for other clovers. Recommended seeding rate: 15-25 lbs/A.

Inoculation with clover inoculant typically recommended.

Peredovik Sunflowers

Sunflowers are a high-yielding broadleaf cover crop that grow quickly and outcompete weeds, and the seeds they produce are also the most popular seed for bird feed. Peredovik Sunflowers grow 4-5 feet tall, the flowers attract butterflies, bees, and other beneficial insects, and the seeds provide a nutritious high-energy food source for birds. All types of sunflower seeds originate from the common sunflower, Helianthus annuus, though there are many specialized and hybrid flower varieties that create different bloom sizes, stalk heights and seed yields. The seeds they produce are similar, however, and sunflower seed is universally popular birdseed. Recommended seeding rate: 40 lbs/A.

Sunn Hemp

Tall-growing summer annual legume, tolerates dryer conditions, high biomass producer, good smother crop. Use as a green manure/cover crop to provide both organic matter and to fix nitrogen during the period between summer and the winter cash crop. Produces significant biomass in 6-7 weeks. High lignin content; after 3 to 4 weeks of growth it begins to get too woody for forage use. Good in mixes to add varying heights to the cover, but keep seeding rate low. Recommended seeding rate: 20-40 lbs/A.

Inoculation with peanut inoculant typically recommended.

Sunn Hemp Tech Sheet

4 way mix - sunflower, sunn hemp, buckwheat, cowpea


A cross between wheat and rye. Using triticale as a cover crop is very similar to using rye—in terms of seeding rate and application—but triticale is a little leafier, little lower in lignin content and later heading than rye. It should also be planted slightly earlier than rye in the fall. Triticale provides over-winter erosion control, soil-building, and nitrogen scavenging. Like rye, triticale also makes an excellent spring emergency forage. Good for mixing with winter annual legumes and annual ryegrass. Recommended seeding rate: 60-220 lbs/A.
