A brief introduction to Cover Crops: Cover crops are used to accomplish a variety of soil improvement issues. Erosion control, increasing organic matter, nitrogen fixation, increasing water infiltration, better soil structure and improving the soil micro flora, all of which aid in sustaining or increasing yields thru healthier soils. A multitude of species are used to accomplish a given response in various part of the country. The following species described are some of the most commonly used in the

Husnot) This is rapidly becoming the cover-crop of choice for producers throughout the
Some times people confuse annual ryegrass (Lolium multiflorum) with cereal rye (Secale cereale). Just by looking at their names you can see the difference. How they grow and can be utilized as a cover crop is also different. Briefly, annual ryegrass as a finer and more extensive root system than cereal rye. Cereal rye has more aboveground (or top growth) than annual ryegrass. For more detailed information on the benefits and management of annual ryegrass, see the various publications listed. Welcome to RyegrassCoverCrop.com! http://www.ryegrasscovercrop.com HAIRY VETCH, also know as WINTER VETCH (Vicia villosa Roth) Hairy vetch is a winter annual legume that has been used as a cover crop for years, primarily as a green manure crop for its nitrogen fixation ability. Its primary use has been in the Southern states due to the extended growing season. Vetch produces limited root growth compared to other legumes and grasses. Hairy vetch requires a specific inoculum to efficiently fix nitrogen. Very little nitrogen fixation occurs below 40 degrees F, and since it takes three weeks for nodulation to develop, very little nitrogen is fixed in the fall in the upper Midwest. For maximum nitrogen production, the spring kill date needs to be delayed as long as possible, which in the upper
Seeding Date: Upper Midwest –July or early Aug. Seeding Rate: 15 -20 lbs/acre should be adequate. Seeding Depth: ½ to 1 inch Caution: Hairy Vetch can have 15 – 30% hard seed which may germinate for several years after planting. Avoid using ahead of wheat. Never let it go to seed in cropping fields. Hairy vetch is a host to soybean cyst nematode. Hairy Vetch as an

Primarily used as a green manure crop and to reduce populations of cyst nematodes. The residues of this crop add humus that improves soil tilth, water holding capacity, and nutrient management. Fall planted radish provides soil cover to aid in erosion control and sequester residual nitrogen remaining from previous crops or manured fields. Oilseed radish is also a highly digestible forage for early and late season grazing. Since it is not tolerant to traffic or shade, it is not recommended to be flown-on early onto standing corn fields. If seeded in late July to early Aug. root growth to a depth of 16 inches is possible before a killing frost. Radish requires 8 – 10 weeks of 60 degree temperature to achieve adequate plant growth and cyst suppression. The plant will die when temperatures reach 28 degrees F. After a killing frost the plant residue will decompose rapidly, leaving the ground bare by spring. Seeding Date: Mid July to Aug 15 Seeding Rate: 14 -18 lbs/acre. Use the lower rate when drilled and higher rate when broadcast. Seeding Depth: 1/4 to ½ inch Note: Can be seeded in a mixture with cereal rye or annual ryegrass, which will add soil cover for spring erosion control after radish has decomposed. Warning—after a killing frost and during decomposition the plants smell like rotting cabbage, which can be very offensive.

Crimson clover is a cool season annual legume, used as forage, soil conservation, and as a green manure crop. Crimson is easily established and will tolerate colder temperatures than other clovers, and will perform on soils with pH ranges from 4.8 – 8.2, suggested pH is between 5.8 – 6.5. It should be established six weeks prior to frost. In No-till application, crimson clover is used primarily for soil cover and nitrogen fixation; having the ability to provide from 65 – 90 lbs. of N for the following crop. Seeding Dates: Southern US : Sept. – Oct.
Seeding Rates: Normally 20–30 lbs. per acre in pure stands. In mixtures with annual ryegrass or cereal rye 15-20 lbs/acre. Seeding Depth: 1/4 inch Seeding Method: Can be seeded with a drill, cultipack-seeder, or broadcast. Note: Need to Inoculate prior to seeding. Crimson clover is a host for the soybean cyst nematode.
