提高氮素利用效率和经济节约可能会导致更好地了解从豆类作物残留物的N释放模式。在塞西尔细桑迪壤土（粘土质、高岭质、热型Kanhapludult）上进行了2年的田间试验，研究了三叶草（Trifolium incarnatum L.）不同生育期对免耕条件下干物质积累、氮素浓度和化学成分的影响及其与氮素释放的关系深红三叶草在春季收获，分为四个生长阶段（营养晚期、开花早期、开花晚期和结籽早期）（.）
Increased N-use efficency and economic savings may result from a better understanding of N release patterns from legume residues. A 2-yr field experiment was conducted on a Cecil fine sandy loam (clayey, kaolintic, thermic Typic Kanhapludult) to examine the effects of crimsom clover (Trifolium incarnatum L.) growth stage on dry matter accumulation, N concentration, and chemical composition in relation to N release under no-tillage management. Crimson clover was harvested in the spring at four growth stages (late vegetative, early bloom, late bloom, and early seed set) (...)
