Abstract

Application of computer technology such as Geographical Information Systems (GIS) to help farmers optimize fertilization, improve soil fertility and protect soil from erosion is currently of considerable interest as a topic of research. The objective of this study was to develop a GIS-based software package that can be used to help farmers select fertilizer application rates and manage soil nutrients. The ease of integration and programming in current digital spatial technology made it feasible to combine a fertilization model with a GIS platform to develop a GIS-based Fertilizer Decision Support System (FDSS) that enables farmers to determine precise fertilizer recommendations through an interactive computer interface. This paper outlines the development and test application of a GIS-based FDSS at Tong-le Village of Baiquan county, Heilongjiang province of Northeast China. The FDSS uses a farm field as the base mapping unit and incorporates data from field samples, farmer surveys and remote sensing, as well as expert knowledge in agriculture, soil science and computer science to develop a spatial database and soil/crop management system. The FDSS is a crop fertilization and management software developed on the SuperMap platform, and will help farmers and managers of agricultural production units to increase their fertilizer utilization efficiency, and thus their net profit. © 2012 Springer Science+Business Media B.V.
