摘要: Nitrogen mineralization of cover plant litter, intercropped or not, in a soil with histor y onion plantation The decomposition winter plants on the surface can increase nitrogen (N) availability during crop cycle. objective this study was to evaluate N litter , intercropeed history plantation. Soil collected, prepared, placed acrylic containers. Dry mass black oats, rye, oilseed radish, oats + radish and rye were added into incubated for 90 days. sampled contents total N, NO 3 - -N NH 4 determined at time zero 18, 36, 54, 72 days after incubation. Values mineral net mineralized
