Abstract: Nowadays, the cultivated land area decreased increasingly, fertilizer was important measure to enhance yield on unit area of crop. Chemical fertilizer played the important role in increasing grain yield, but it had negative effect on soil, such as nutrient imbalance, aggravating acidification, etc. However, organic fertilizer could improve soil nutrients; it also could improve the physical and chemical property of soil, balance the nutrition and fertilize soil. This review deals with the effect of organic fertilizer on balancing the nutrition, improving the physical and chemical property of soil, increasing the diversity of microbial community and improving the enzyme activity in soil. The paper summarizes the latest research methods and advances of improvement of soil fertility. We want to provide evidence for reasonable and highly efficient to use organic fertilizer in agricultural production, also for improving the soil condition to a maximum extent by organic fertilizer. The final purpose is increasing crop yield and quality to realize continuous development of agriculture.
