Abstract: It has become the consensus of the whole society to reduce the application of chemical fertilizer and increase organic fertilizer, but because the understanding of the characteristics of organic fertilizer is not comprehensive, there is unreasonable use of organic fertilizer in the production process at the present. In this paper, the effects of organic fertilizer application on soil physical and chemical properties, soil nutrient supply characteristics, soil biological characteristics, nutrient use efficiency and crop yield were reviewed, and the corresponding suggestions for rational use of organic fertilizer were put forward, in order to provide reference for reducing crop yield and environmental risk caused by reducing chemical fertilizer application and increasing organic fertilizer application.

Key words: Organic fertilizer, Soil nutrient supply, Nutrient use efficiency, Crop yield
