Abstract: The effects of different meaures of fertilizer application on crop yield and accumulation of NO-3-N in the profile of three major soils were studied according to the result of a 18 years located experiment.The results showed that the mixed application of N and P or N,P and K would be an efficient way for raising crop yield and had accumulation of NO-3-N in the profile of three major soils.

Key words: Fertilizer application, Accumulation of NO-3-N, Crop yield, Different soil
