Each year (1977-1985) the cover crop was seeded into standing corn in early September, before harvest. Corn was planted in mid- May in both no-till and conventional tillage plots. At this time the cover crop was killed with herbicide. Soil organic matter, N fertility, soil structure and soil water were all analyzed. It was found that grain yields with a hairy vetch mulch and 100 kg/ha applied N increased at an average rate of 500 kg/ha/yr, relative to yieldsCollection: Reprints Collection
