综述指出，虽然有机农业生产方式可有效地减少氮素流失，但仍然存在流失的可能性。
It has been emphasized that although nitrogen leaching is reduced efficiently on organic farming, a possibility of leaching losses still exists.
不施用有机肥时，水溶性无机态氮为水溶态氮素流失的主要形态，所占比例在60％左右；
Without the application of manure, the inorganic nitrogen is the main pattern of the water-solution nitrogen loss, occupying about 60%.
施用有机肥后，水溶性有机态氮是水溶性氮素流失的主要形态，平均占到60- 70%以上。
With the application of the organic manure, the organic nitrogen is the main pattern of the water-solution nitrogen loss, of which the average occupies more than 60-70%.
泥沙氮素含量随着产流时间的延长呈下降趋势，而流失累积量测呈逐渐增大趋势。
With delay of runoff yield time, the nitrogen concentrations in runoff and sediment drop off, whereas, the accumulation amounts of nitrogen loss rise gradually.
