摘要: The soil testing and fertilization recommendation technology can prevent improper fertilization and low utilization ratio of fertilizers. GIS spatial analysis module can reduce high costs and increase efficiency of conventional soil testing and fertilization. The purpose of this study comments on the previous researches of GIS application in soil testing and fertilization, has put forward the advantages and inevitable disadvantages, and demonstrates the efficiency of soil resource information database to improve the technology of soil testing and fertilization. It can notably cut down the costs and improve practicability of models when the spatial soil nutrient database is introduced into the development of soil testing and fertilization.
