Abstract

Field experiment was conducted to investigate the accumulation of soluble organic nitrogen under intensive vegetable production pattern in Northeast China. The results showed that the amount of soil soluble organic nitrogen was increased by 114.2% and 184.2% in the treatments M₁ and M₂ compared with CK, and its corresponding percent accounting for the total soluble N was increased by 74.9% and 123.7%, respectively (P <; 0.01). This suggested that the substantive application of organic manure significantly elevated the accumulation of soluble organic nitrogen, and then extended its leaching risk into deeper soil layers under the intensive vegetable production process.
