Fertilization is the major measure and agricultural technology to improve the production of crops. However, blind fertilization and excessive fertilization have reduced the use efficiency of fertilizer in many years, which resulted in ecological environment deterioration as well as soil degradation. On the backdrop of soil testing and formulated fertilization project promotion, software like MapGIS, ArcGIS and Cultivated land resource management information system were used to build relative evaluation model and fertilization index system. Through analyzing the farmland and rice adaptability in Dong’an County, the expert system on soil testing and formulated fertilization was established and promoted.
