Book Description
Integration of cover crops in corn (Zea mays L.)-soybean (Glycine max Merr.) rotations may reduce negative impacts on crop yield, soil health, and the environment. Two experiments investigated cover crops in corn-soybean based rotations. Lolium multiflorum (annual ryegrass, AR) and Trifolium pretense (red clover, RC) were planted or broadcast into V5 corn harvested for grain or silage. Cover crop biomass in the spring ranged from 0 to 1.63 Mg ha-1. Grain corn yields were unaffected by cover crops. In the second experiment, three rotations were established: 1) continuous soybean, 2) corn-soybean, and 3) continuous soybean with broadcast or drilled AR or Secale cereale (cereal rye, CR). Cover crop biomass measured late fall was consistently low (
