摘要: The yield and flux of nitrous oxide (N2O) emitted from continuous cereals (with without urea), legumes ⁄ cereal in rotation legume all with or organic manure was monitored from January 2004 to February 2005. All treatments except had phosphate added. grown July–October 2003 pearl millet (Pennisetum glaucum) the legume a bean (Phaseolus vulgaris). 10 m · plots were established semi-arid climate in Mali. addition both inorganic fertilizers increased N2O emissions. Continuous treated urea significantly less N2O (882 g N⁄ ha per year) than receiving no manure(1535 year). Growing N-fixing crops did not increase emissions. This study supports the new practice of growing legumes as an environmentally sustainable system Mali
