The SFIS (Soil and Fertilizer Information System) for Heshengqiao Town was developed in this study using Visual FoxPro 6.0 in Chinese Windows 98 Operating System. It was based on the data obtained from second Soil General Survey of Hubei Province and the two standards required by the Ministry of Agriculture were also taken into consideration. The data were classified, transformed and saved in the form of database. Soil attribute database, administrative code database and parameter database for prescription fertilization were set up. Based on those databases, five application modules were developed, including modules of fertility appraisal, soil improvement, comprehensive inquiry, prescription fertilization and fertilizer demand. Help system and utility tools including notebook and calculator were also employed as assistant module. As an exploring program for the establishment of Soil and Fertilizer Information System, the study was trying to combine computer information technology with soil and plant nutrition technology. The SFIS is a software applied in agriculture. Its data structure, technology standard and method can be used in all kinds of units on agricultural management ranking from a town or a county to a province.\;
