There is a new emphasis on Hairy Vetch as a winter cover crop. It has been known to add 60-70 lbs. nitrogen to the soil-should be seeded in September for fall cover crop. Seeded alone, plant 20-30 lbs. per acre. In mixtures, use 10-15 lbs. Hairy Vetch and 1/2 to 1 bushel small grain. A good mixture in the spring is 15 lbs. Hairy Vetch to 1 1/2 bushel oats per acre. Do not seed vetch in small grain to be harvested as grain.
