These Low growing, self-reseeding legumes produce high N contribution. Fall planted subclovers thrive in Mediterranean conditions of mild, moist winters and dry summers on soils of low to moderate fertility. Popularity of subclovers is growing in the coastal mid-Atlantic and Southeastern US ( Hardiness Zone 7 and warmer). Subclovers are used in thousands of acres of almond orchards in California. Some cultivars tolerate alkaline soils and waterlogged conditions.
Mustard is a name that is applied to many different botanical species, including white or yellow mustard (Sinapis alba, sometimes referred to as Brassica hirta), brown or Indian mustard (Brassica juncea)—sometimes erroneously referred to as canola—and black mustard (B. nigra (L.). The glucosinolate content of most mustards is very high compared to the true Brassicas. Mustards also produce significant biomass, and capture high amounts of residual N. Because mustards are sensitive to freezing, winterkilling at about 25º F, they are used either as a spring/summer crop or they winter kill except in areas with little freeze danger. Brown and field mustard both can grow to 6 feet tall. In wheat/mustard-potato systems, Mustards show promise for reducing or eliminating the soil fumigants.
Mammoth Red Clover
A dependable, low-cost, readily available workhorse that is winter hardy in much of the U.S. (Hardiness Zone 4 and warmer). Easily overseeded or frostseeded into standing crops, it creates loamy topsoil, adds a moderate amount of N, helps to suppress weeds and breaks up heavy soil. Its most common uses include forage, grazing, plowdown N and, in warmer areas, hay. It's a great legume to frostseed or interseed with small grains where you can harvest grain as well as provide weed suppression and manage N.
Ladino is a long-lived perennial, which spreads by creeping stems or stolons that root at the nodes. A giant form of white clover that is very high in protein, vitamins and minerals. It's a good producer of high-quality feed and is utilized extensively as a soil building crop. It's an excellent legume to use in combination with other legumes and grasses.

Hairy Vetch is a hardy, winter annual legume that can be planted in either fall or spring. It is used for cover cropping, hay, pasture or as erosion control and is commonly planted with cereal grains. Few legumes match hairy vetch for spring residue production or nitrogen contribution. Widely adapted and winter hardy through Hardiness Zone 4 and into Zone 3 (with snow cover), hairy vetch is a top N rovider in temperate and subtropical regions. The cover grows slowly in fall, but root development continues over winter. Growth quickens in spring, when hairy vetch becomes a sprawling vine. Nitrogen source, Soil conditioner, Early weed suppression, Good with grains, Moisture-thrifty, Phosphorus scavenger, Fits many systems, Widely adapted.

Cowpeas are the most productive heatadapted legume used agronomically in the U.S. They thrive in hot, moist zones where corn flourishes, but require more heat for optimum growth. Cowpeas protect soil from erosion, smother weeds and produce 100 to 150 lb. N/A.
Buckwheat is the speedy short-season cover crop. It establishes, blooms and reaches maturity in just 70 to 90 days and its residue breaks down quickly. Buckwheat sup -presses weeds and attracts beneficial insects and pollinators with its abundant blossoms. It is easy to kill, and Buckwheat’s dense, fibrous roots cluster in the top 10 inches of soil, provides an extensive root surface area for nutrient uptake. It takes up phosphorus and some minor nutrients that are otherwise unavailable to crops, then releasing these nutrients to later crops as the residue breaks down.
A fast-growing summer annual, Berseem clover can produce up to 8 tons of forage under irrigation. It's a heavy N producer and the least winter hardy of all true annual clovers. This makes it an ideal winterkilled cover before corn or other nitrogen-demanding crops in Corn Belt rotations. Berseem clover draws down soil N early in its cycle. Once soil reserves are used up, it can fix 100 to 200 lb. N/A or more. It establishes well with an oat nurse crop, making it an excellent cover for small grain>corn>soybean rotations.
A newer cover crop used in the Southeastern U.S., balansa clover (Trifolium michelianum Savi) is a small-seeded annual legume with superior reseeding potential compared with other legumes, including crimson clover. Well-adapted to a wide range of soil types, balansa performs particularly well on silty clay soil with a pH of about 6.5. Established stands tolerate waterlogging, moderate salinity, and soil pH from 4.5 to 8.0. It does not do well on highly alkaline soils (30). It is considered marginal in Zone 6B.
Australian Winter Peas (Field Peas)
High N-fixers, AWP produce abundant vining forage and contribute to short-term soil conditioning. succulent stems break down easily and are a quick source of available N. AWP grow rapidly in the cool, moist weather they encounter as winter annuals in the South, and as early-sown summer annuals in the Northeast, North Central and Northern Plains areas. Austrian winter peas, can withstand temperatures as low as 10° F with only minor injury, but they don’t overwinter consistently in areas colder than moderate Hardiness Zone 6. Under a long, cool, moist season during their vegetative stages, Austrian winter peas produce more than 5,000 lb. dry matter/A. Austrian winter peas are top N producers, yielding from 90 to 150 lb. N/A, and at times up to 300 lb. N/A. Water thrifty, Quick growing, Forage booster, Long-term bloomer ( an early and extended source of nectar for honeybees), Chill tolerant.

Black Oat (Bristle Oat)
Black oat (Avena strigosa L.) is the No. 1 cover crop on millions of acres of conservation-tilled soybean in southern Brazil, and is increasing use the southern USA (Zones 8-10). Black oat produces large amounts of biomass, similar to rye. It maintains a narrower carbon to nitrogen (C:N) ratio than rye so it cycles nitrogen better than rye, important for nitrogen management in conservation tillage systems. It breaks disease cycles for wheat and soybean and is resistant to root-knot nematodes. It is very resistant to rusts and has excep tional allelopathic activity for weed control. It is easy to kill mechanically.
Barley is an annual or biennial grass that is widely cultivated for yielding grain for breakfast food, animal feed and in malt beverages. Black barley, awnless, hooded, 2 row, 6 row, diﬀerent awn lengths and diﬀerent spike lengths characterize the many barley types.

Phacelia tanacetifolia (Lacy Phacelia)
Phacelia tanacetifolia , aka. Lacy Phacelia, is used extensively in Europe, both as a cover crop and bee forage, and is gowing in popularity & use in the US. Phacelia is quick to grow and flower and grows well in dry soil. It does a good job of limiting nitrate leaching when planted in early fall. It winterkills at about 18°F. In cooler regions, it can be used as a between cash crops cover crop in the summer. Phacelia is listed as one of the top 20 honey-producing flowers for honeybees and is also highly attractive to bumblebees and syrphid (hover) flies. Phacelia's habit of flowering abundantly and for a long period can increase beneficial insect numbers and diversity, because it provides high quality nectar and pollen.

EverLeaf ™126 is a delayed heading oat and much of its forage mass and quality come from an extended maturity. Since the plant is naturally vegetative for a longer period, biomass accumulation is extraordinary. EverLeaf™ 126 has a compact panicle that offers an attractive product when baled.
A tropical legume, sunn hemp (Crotalaria juncea L.) can produce more than 5,000 lb. dry matter/A and 120 lb. N/A in just nine to 12 weeks. It can fill a narrow niche between harvest of a summer crop and planting of a fall cash or cover crop and is especially fitted to vegetable production. Sunn hemp sown by September 1 following a corn crop in Alabama, for example, can produce an average of 115 lb. N/A by December 1. Sunn hemp is not winter hardy and a hard freeze easily kills it. Sow sunn hemp a minimum of nine weeks before the average date of the first. Sudangrass is highly palatable and high-yielding summer annual forage. Adapted to many types of soils and environments, use with caution when grazing or haying because of nitrates and prussic acid. Sunn hemp seed can only be produced in tropical areas, eliminating the threat of re-seeding /weediness to only the very southern regions of the Gulf States.
Rapeseed (or Canola)
Besides their use as an oil crop, these species are also used for forage. If pest suppression is an objective, rapeseed should be used rather than canola since the breakdown products of glucosinolates are thought to be a principal mechanism for pest control with these cover crops. Rapeseed has been shown to have biological activity against plant parasitic nematodes as well as weeds. Due to its rapid fall growth, rapeseed captures high amounts of residual N and accumulates significant amounts of aboveground biomass.
VITALITY Radish is a multi-purpose “Daikon type” (Raphanus sativas var. longipinnatus), also referred to as forage or fodder radish and has been selected for use in cover crop systems to improve water quality, and increase farmland productivity. VITALITY Radish is an agronomic tool to alleviate soil compaction, suppress weeds, capture, recycle & redistribute N and other nutrients in the soil profile, enhance seedbed for following crop, reduce nitrate leaching, reduce runoff & control erosion, build soil organic matter & microbial action, and attract beneficial insects.
