A field plot experiment was conducted to study the effects of combined application of organic and inorganic fertilizer on soil nitrogen runoff in vegetable field.The results showed that fertilizer application increased the nitrogen loss via runoff.The highest losses of total nitrogen
nitrate nitrogen and ammonium nitrogen were 4.20
1.22
2.30 kg/hm2
respectively
as treated by inorganic fertilizer alone.The nitrogen loss decreased significantly with the increased combined application of organic and inorganic ...
