Abstract: This paper discussed the characteristic of information technology applied on soil nutrient management and fertilizing technology in occident, analyzed the requests of soil determination and prescription fertilization for information technology and it developing trend in china, pointed the requests, tasks and contents of information processing in it at present in our country, and analyzed the questions about it at Agricultural technology extension station in counties. The application of information technology in soil determination and prescription fertilization mainly conclude these, (1) applying the database technology and GIS, and processing the data about soil and fertilizer and the maps connected according to the standard, to establish the attribute database and space database, and management system. (2) using GIS and database, combining the application, to establish application system such as tilth estimate system and applying decision system.(3)utilizing network technology to realize database sharing and long-distance applying decision on web.
