The outstanding strategical target of the Chinese agricultural policy for the upcoming decades can be summarized as follows: producing enough agricultural products under sustainable economic and environmental conditions. One important instrument to address this challenge is the Soil and Fertilizer Information System of China (SOFISC). SOFISC is a GIS-supported computer system especially designed for decision-makers and researchers involved in agricultural and all related industrial and environmental areas of the economy. It provides information about the development of soil fertility and productivity as well as fertilizer application and efficiency in all the 30 provinces and 2,300 counties of China. Future effects of decisions about fertilizer use can be analyzed and evaluated on a national and regional scale.
