In order to study the fertilizer quantity to maize,which was influenced by production level of different areas and nutrition of soil,we developed the maize precise fertilization expert system by combining the artificial intelligence techniques,GPS and GIS,with the fertilization for break,taking the mathematics model of nutrient equilibrium as the core,and adopting the object-oriented programming technology.The system mainly resolves the two problems of yield prediction and precise fertilization and ultimately print for the user the consultation sheet of maize precise fertilization,including predicted yield,variety,fertilizer quantity and the situation of benefit analysis.The practice result has showed that the application of this system could reduce cost,make present increase yield and benefit,and realize low cost but high production.
