BuckwheatBuckwheat

Sow Buckwheat any time between last spring frost and 1 month prior to first fall frost. A great quick summer crop, fast growing plants choke out weeds. Bees love the white flowers that appear in 4 to 5 weeks.

The tender stems are easy to cut down when the crop's done. For a fall/winter cover crop we recommend sowing buckwheat together with crimson clover. The buckwheat acts as a nurse crop for the crimson clover during the heat of the day. In the fall, the buckwheat is killed by frost. Organically grown. 

Mature in 30-45 days as a green manure crop and 80 days for a grain.

Crimson CloverCrimson Clover

Crimson clover fixes up to 200 pounds of nitrogen per acre, and prefers well-drained, loam soils with good organic matter content for best results. It is an excellent choice for under-seeding as it grows well in the shade of other crops. Easier to incorporate in the spring than Hairy Vetch.

Do not use for frost seeding as it won't handle the cold. Crimson clover will not re-grow after close grazing or mowing once flowering has begun. Crimson clover does best in cool, humid weather and will perform poorly in the heat of summer. 

Blooms in 90 days.

Fall Green ManureFall Green Manure

Versatile choice for late summer and fall planting. This ready-made mix is comprised of winter rye, field peas, rye grass, crimson clover, and hairy vetch. Vigorous late summer growth provides winter erosion control. The peas, clover, and rye grass will winter kill to provide organic matter and soil cover. The hairy vetch and winter rye will regrow in the spring to provide nutrients for crops to utilize. Because the seeds of this mix vary in weight and size, it is best seeded with a grain drill.

The number of days to bloom varies.

Hairy Vetch OrganicHairy Vetch Organic

Use Hairy Vetch cover crop seeds for short-term, legume green manure for nitrogen fixation. Sow spring to late summer with or without grain, grass, or field peas. When sown late summer, spring regrowth is vigorous and nitrogen producing for tilling in before planting the spring garden crops.  

May have some allopathic properties, so it is best to allow 2-3 weeks between incorporating and seeding of small-seeded crops. This selected hardy strain is widely adapted and withstands all but severe winters if sown in late summer or fall. 

Harvest in 60 days.

Iron and Clay Cover CropIron and Clay Cover Crop

Iron and clay cowpeas can be used in one of three ways. They can be eaten, nitrogen fixation or as fodder for animals. Southern favorite. Bushy 2-3 feet plants bear prolifically. 6-9 inch pods with large, creamy-white seeds, 18-20 seeds/pod, easy to shell. Unusually, seeds have a taste between English peas and cowpeas when fresh. A great cover crop for warm weather and Southern growers. Grown much like soybeans. Frost sensitive, but fast growing to 2 1/2 feet  in warm/hot weather. Sow mid-spring once soil has warmed. Drill at 25-50 pound per acre or broadcast up to 120 pound per acre, 1/2 to 1 inch deep. Relatively long taproots help withstand drought. Cowpeas are not tolerant of high weed pressure or wet soils and will perform poorly in these conditions. If planted thickly, they will smother out weeds. Cowpeas can also be used for under-seeding in spring crops and tilled under prior to fall-planted crops. They can produce as much as 315 pound per acre nitrogen, although 130 pound per acre is more typical. High organic matter production. They can also be used as fodder for animals.

Harvest in 80 days.

New Zealand Clover Cover CropNew Zealand Clover Cover Crop

An improved pasture white clover. Previously sold under the name White Dutch Clover. Once established, white clover can handle foot and tractor traffic better than other clovers. The fibrous root system typically is in the top 8" of soil, although it does have up to a 40" tap root in the first year which dies each fall, leaving a passage for water to percolate through. More heat tolerant than some of the larger clovers, it is a low-growing (to 12") perennial that can be sown into long-season row crops during the season to provide a "living mulch." Sow after first cultivation at 1/4 lb. per 1,000 sq.ft. and rake or cultivate to cover. Also used for green manure, hay, and pasture.

Annual rye grass grows vigorously under a wide range of soils and climates. It is tolerant of wet soils and temporary flooding, and will grow in sandy soils, but is better adapted to heavy clay or silty soils. Annual rye grass tolerates a pH range of 5-8 with the optimum between 6 and 7. Can become a weed if allowed to set seed.

Sweet CloverSweet Clover

Sweet Clover is a tremendous green manure and honey plant. Sweet clover can grow nearly anywhere, with as little as 16 inches of rainfall per year. It has deep tap roots that mine soil nutrients and water from deep within the soil. It is better than many of the other clovers for nutrient recycling and appears to have a greater capacity to extract potassium, phosphorus and other soil nutrients from insoluble minerals.

Sow in spring to summer at 1/2 lb./1,000 sq.ft. (15 lb./acre) as an annual, or let grow the next year over 6 ft. tall. Should be grown with 1½ to 2 bushels of oats as a "nurse" crop. Sweet clover is slow to establish the first year and may have some winter kill without adequate snow cover.

Second year growth is tremendous. Will fix as much nitrogen as alfalfa and doesn't require an acid soil. Can produce as much as 170 lb. of nitrogen per acre although 100 lb. per acre is closer to the average. Excellent conditioner for poor and thin soils. Mostly yellow with some white flowers. Organically grown. 

Harvest in 70-90 days.
