Abstract

Abstract: An improved fertilizer practice (IFP) suggested, which increases the Nuse efficiency by 20—30% and rice yield by 400-1004kg/ha, as compared with the conventional one(CFP). Based on the results of field experiment, the ecological impact of the improved fertilizer practice was discussed in respects of reducing atmospheric and water pollution, increasing soil Nfertility and benefiting people and society.

Key words: Paddy field, Fertilizer practice, N use efficiency, Ecological impact
