This study proposed an Ecological Balanced Fertilization Model (EBFM) based on microbial compound fertilizer. We selected nine evaluating factors as Minimum Data Set (MDS). This MDS includes nutrition and microorganisms. According to the composition of chemistry nutrients to soil, microbial fertilizer and the level of effective fertilizer nutrient supply, we use the EBFM of the specific crops to develop the ratio of various elements. Finally, the Weighted Fuzzy Clustering Algorithm (WFCA) is used to evaluate the soil nutrient spatial changes of proposed EBFM after fertilizer operations comprehensively. The experiment shows that by using the proposed EBFM three years the spatial differences of soil nutrient has become narrowed. The overall fertility of soil has been increased.
