Based on the technology of ComGIS,the recommend system for variable-rate fertilization in precision agriculture was developed.It integrated soil test nutrition data,object yield obtained by historical crop yields of past years,fertilization model and expert knowledge to realize intelligent decision and made field fertilizer prescription.Moreover,it enabled the data communication between system and intelligent agriculture machinery,and the prescription made by the system can be loaded on variable-rate fertilizer and direct variable-rate controller to implement variable-rate fertilization successfully.
