Abstract :
Base on the organic matter, total nitrogen, available phosphorus and potassium content in the cultivated land of The 20 District in Dehui 20, it comes a study on using the decision tree ID3 algorithm for the evaluation of farmland fertility levels. Through experimental analysis, it gets the number of grade 6, grade sub-region soil nutrient content is similar or smaller differences, and significant differences among grades. Fertility Evaluation based on the ID3 algorithm farmland can be used for variable rate fertilization in the guidance of precision agriculture, to provide an effective division for farmland fertility level partition.
