Management of red clover as a cover crop
Consider the following management tips for red clover, one of the most widely used cover crops.
Red cover’s high adaptability and biomass yield makes it one of the most ideal candidates for cover crops across the United States and world. It has average nitrogen production and offers a good ground cover. It should be used in rotation or simultaneously with corn, oats and soybeans.
Red clover establishes well in cool climates and can grow in almost any soil type. It germinates very quickly, but is a slower growth clover. For this reason, it is recommended to sow it when there is another crop present or a residue of another crop. For example, sow red clover with a rye-grass to keep soil from drying out while the red establishes.
Red clover can be over seeded into dormant winter grains, summer annuals, corn and after a wheat harvest at 10-12 pounds per acre. In general, it should be drilled at 8-12 pounds per acre, broadcasted at 9-13 pounds per acre and aerial applied at 9.5-14 pounds per acre.
Red clover should be killed at about mid-bloom of its second season. It can be terminated mechanically by being chopped or mowed any time after blooming starts.
Medium red clover
Also known as multi-cut clover, medium red clover should be cut once late in the seeding year and twice the following year. Use it as hay or grazing in the second season for maximum nitrogen production.
Mammoth red clover
Mammoth clover produces a large amount of biomass and nitrogen in the first cutting, but less in later cuttings. Use this single cut clover for a single year all over the clover field.
Red clover works well in a rotation between two non-leguminous crops. It is found that it can be used to support continuous corn growth without commercial fertilizer.
