Cover cropping is a practice that can benefit soil-crop systems in several ways: increasing
nitrogen (N) supply for the next crop, reducing soil erosion, improving soil physical properties, …

Winter Legumes as a Nitrogen Source for No‐Till Grain Sorghum1

WL Hargrove - Agronomy Journal, 1986 - Wiley Online Library
