Abstract

Abstract: By the data sampled from wusi farm ,input of fertilizer and the degree of the soil index of fertilizer are calculated using the empirical formula . At the same time,the variable input map of fertilizer and the fertilizer map are maped using GIS. The result shows:There exits difference with the fertilizer whin the field and the input of fertilizer is different too.

Key words: model, soil index of fertilizer, GIS, variable input of fertilizer, model, soil index of fertilizer, GIS
