Single Species Seed
Nitro Radish (Daikon)
Rapid fall growth in short windows, allows radishes to fit perfectly into a traditional corn and soybean rotation. Radish residue breaks down very quickly in the spring, leaving a clean seed bed until early April. The residue has been proven to inhibit small seeded annuals from germinating. Nutrients that were scavenged are readily released back into the soil for the subsequent crop. A field planted in radishes, will allow the soil to dry and warm faster in the spring. The large root channel left behind is rich in nutrients, allows tremendous water infiltration, reduces water erosion, and a path for crops roots to follow through compacted soil layers. During decomposition, radish biofumigates the soil which can reduce pest and nematode populations.

Smart Radish
Green Cover Seed is proud to market the all new Smart Radish. It is bred specifically for the cover crop and soil health market. The variety has a trait for higher plant tillering to provide more leaf area and higher plant biomass than many other radish options for forage, soil, cover and green manure. Larger leaves mean more solar collection area to harvest the sun’s energy, and the smoother leaf means it’s better for forage and grazing.

Okra (Clemson Spineless 80)
Okra is a great way to add diversity to almost any mix. With a deep taproot and good grazing characteristics, above and belowground livestock will benefit from this plant. Okra also has excellent drought tolerance. It can be used in both warm and cool season mixes. Add okra to help break up compaction, build soil, and provide feed for animals.

Cowpeas (Iron & Clay)
Cowpeas are one of the most popular warm season legumes. They love the heat, they tolerate drought, and they offer nitrogen fixation in a soil building mix, or higher protein in an annual grazing mix. Cowpeas have a long maturity which means when they are planted at the beginning of summer, they can achieve a lot of growth before temperatures cool down into fall.

Northern Cereal Rye
Cereal Rye has an excellent fibrous root system that alleviates surface compaction. Rye can be successful planted later then almost any other cover crop due to its low germination and growth temperature requirements. Cereal rye is known for being the best cereal crop at retaining residual N. It's typical for a fall planted cereal rye crop to scavenge on average 25 to 50 lbs of N, with cases scavenging in excess of 100 lbs of N. The vigorous spring growth has successful weed suppression through competition and allelopathic chemicals. Rye can be terminated in the spring through the alternative methods of rolling, mowing, or crimping after boot stage. Rye will out yield any other cereal crops when planted in droughty, infertile, or sandy soils.

Japanese Millet
Japanese millet, known for its quick maturity, usually offers a lower forage yield compared to other millet varieties. However, it stands out for its superior post-maturity palatability when compared to foxtail millet and its impressive regrowth capabilities. Additionally, Japanese millet exhibits remarkable resilience to waterlogged soils, thriving even in standing water, making it a valuable choice for enhancing duck habitat and nourishment in food plots.

Florida Broadleaf Mustard (Shield)
Mustard produces significantly more glucosinolates than other brassicas, which biofumigates the soil during decomposition, proving to be toxic to many soil pathogens and pests. If this is your goal than another mustard species should be utilized, since this cultivar isn't as suited for this purpose. Growing mustard in a potato rotation was observed to increase tuber quality and yields similar to that of chemically fumigated fields. Other documented effects of having mustard in your rotation is suppressing potato early dying and reduced root rot in pea rotations. Some customers are concerned that these mustards are difficult to control like their wild cousins but actually they can be easily terminated with many commonly utilized herbicides. Mustard forage is known for its ability to be utilized as a natural dewormer in grazing systems.

Sorghum (Egyptian Wheat)
Surprise! Egyptian wheat is a… sorghum. As one of the tallest growing cover crop species, this is a good biomass builder that can also be used as a view blocker. Eventually what goes up must come down so when freezing or wind damage occurs, the seed heads which may be 12 feet high lodge over to the ground to make great feed and habitat for game birds.

Spring Lentil
Lentils thrives in cool, dry conditions where they can remain relatively free of disease hence, they are commonly grown in the norther Great Plains. With a shallow rooting structure that doesn't have the ability to reach subsoil moisture, lentils are a great option in front of cereals or deep rooting crops. If excessive moisture is present during the growing season it will delay plant maturity. This will be excellent for producers who want to plant a summer fallow mixture where the mix can continue to grow under ideal conditions. Lentils are known for their ability to emerge through thick cereal stubble due to their strong seedling vigor. With rapid seed germination, seedlings generally out grow the threat of insects or disease pressure during establishment. Lentils can also house mycorrhizal fungi. Mature lentil straw can be an option for feed as it is much higher in CP, digestibility and palatability when compared to cereal straws.

RC Big Rock Switchgrass
RC Big Rock Switchgrass is a new late season variety of upland switchgrass developed from Cave-in-Rock. This is a native perennial warm season grass that is extremely productive, reaching 8 feet tall on the best soils of the Midwest. It also establishes faster than most native grasses because it has larger seeds with reduced dormancy and more seedling vigor. RC Big Rock can grow 2 ft tall in 2 months in the seeding year. This is a multi-purpose variety to be used for wildlife habitat, soil conservation, and forage throughout the greater Midwest where annual rainfall averages 30-50”.

Sudangrass (Piper)
Sudangrass is a super fast growing, fine stemmed warm season annual grass. If summer weed suppression was the goal, this would be one of the best species to accomplish that. Sudangrass is commonly crossed with sorghum to make sorghum-sudan which Takes the fast, tall growing, fine stemmed traits of sudangrass and combines it with the wider leaf and oftentimes higher forage quality of sorghum. For the best grazing digestibility, a BMR (brown midrib) sorghum sudan is usually used which has less lignin.

Siberian Kale
Siberian Kale like many other brassicas are a great addition to mixes for deep taproots to access nutrients and water deep in the soil profile. This deep taproot allows for following crop roots or water to go deep in the soil profile. The wide leaf and good palatability of kale works great in grazing mixes for livestock. A good cold tolerant brassica can last deep into the fall for good fall and early winter grazing.

Brown Mustard (Variety Not Stated)
Mustard produces significantly more glucosinolates than other brassicas, which biofumigates the soil during decomposition, proving to be toxic to many soil pathogens and pests. To best utilize these glucosinolates, mature green vegetation should be turned into the soil. In no-till operations you will still benefit from having this species for this use. When allowed enough growing season, brown mustard stem residue can remain erect throughout the winter months, aid in capturing snow to help build moisture in the soil profile. Growing mustard in a potato rotation was observed to increase tuber quality and yields similar to that of chemically fumigated fields. Other documented effects of having mustard in your rotation is suppressing potato early dying and reduced root rot in pea rotations. Some customers are concerned that these mustards are difficult to control like their wild cousins but actually they can be easily terminated with many commonly utilized herbicides.

Cucurbit Blend
The cucurbit plant family includes plants like squash, pumpkins, and gourds. These warm season annual broadleaves are known for being viny which can be a very desirable trait to have in a cover crop blend. In the case of a row skip when planting or a troublesome soil spot in the field, nearby cucurbits will vine out to soak up the sun where nothing else is growing. These cucurbit fruits can also add nutrition to winter stockpile forage mixes as the cold weather softens their outsides and cattle learn to eat the seeds and fruit flesh.
