Abstract:

In this study, four different fertilization treatments were conducted in 12 dry sugarcane plots with single row and single irrigation to detect the nitrogen and phosphorus content of runoff water generated by natural rainfall during the growth period of sugarcane under 4 fertilization schemes. The results showed that: Total nitrogen and total phosphorus in CK runoff were always at a low level; From the long-term trend, the content of TN in runoff showed as CT>BS>NSPC-BS; Total phosphorus content in runoff water showed as CT>NSPC-BS>BS. Total nitrogen loss load in runoff showed as NSPC-BS<; total phosphorus loss load in runoff BS<NSPC-BS<CT.

Key words: sugarcane, runoff, nitrogen, phosphorus, organic fertilizer
