摘要: Leaching of organic nitrogen (DON) and carbon (DOC) was measured after cultivating grass-clover different age. It found that DON escpecially DOC lost in considerable amounts, the leaching depends upon crop management. The highest concentrations were bare soil treatment, whereas concen-trations catch treatments between 1.2 3.2 mg N L-1. showed opposite trends compared to with higher values (296 - 310 kg ha-1) than (174 217 ha-1).
