Abstract: Field experiments and simulation tests show that the nitrate content in percolating water is positively correlated with the application rate of nitrogenous fertiIizers. The nitrogen specific load of agricultural non-point sources is obtained by statisticaltreatment, and the effective countermeasures for nitrogen pollution control from these sources are put forward.

Key words: Agricultural non-point sources pollution(ANPSP), Nitrogen specific loads(NSL), Saving-water irrigation, 15N-tracing technique
