Abstract
The current precision fertilization technology of maize is still incomplete and unsystematic. In the paper, according to the fact of maize production of black soil zone in Jilin province, spatial variability of soil nutrient is studied, precision fertilization model of maize is introduced, a web-based expert system for maize precision fertilization is developed. Finally, the precisionfertilization is implemented by the variable rate fertilizer. The practice shows that, by the program proposed in this paper, the maize yield was increased by nearly 10%,and the fertilizer was saved about 10.5%.Furthermore,the profit and maize quality was increased and the environmental pollution and input cost was decreased.
