The invention discloses a prediction method and a prediction model for the effective cadmium content in soil and application of the prediction model, and relates to the technical field of soil nutrient prediction. Comprising the following steps: (1) collecting a plurality of farmland soil samples, and respectively measuring key nutrient indexes; (2) recording the measured data, and carrying out statistics and drawing; (3) performing correlation analysis on all statistical data, and determining indexes having significant correlation with effective cadmium; (4) establishing a prediction model of available cadmium in the soil through a multiple linear regression analysis method; and calculating the effective cadmium content in the soil according to the prediction model. The prediction model and the prediction method provided by the invention are simple, have few variable parameters and high prediction precision, can effectively predict the content of available cadmium in the soil, and provide reference for scien
