摘  要:
The software MapInfo was used to establish a soil nutrient information database and a management method of fertilization operation in the field for variable rate fertilization in precision agriculture. Soil nutrient maps of the cultivated land were made based on the soil sampling data. The difference of soil nutrient between operation units can be learned from the maps, and the decision and operation for variable rate fertilization can be made according to the difference. The results of the method showed that the soil nutrient information database on the field was suitable for variable rate fertilization decision and management in precision agriculture.
