Organic fertilizer has high content of organic matter, complete nutrients, strong and soft fertilizer, lasting and stable, and has the good effect of improving the physical and chemical properties of soil. It is the main energy and nutrient source of soil microorganism and is an important measure to reduce agricultural cost. It is to maintain and promote soil Nutrient balance, soil fertility an important part of the application of fertilizer to break the inherent closed loop of material in the agricultural modernization, industrial production has the advantages of organic fertilizers is an important measure to promote agricultural production, agriculture An important symbol of modern civilization.According to the requirements of continuous agriculture and modern agriculture, emphasis should be put on both organic and chemical fertilizers, both of which should be combined with each other in order to meet the demand for fertilizers, regulate soil nutrient balance, The purpose of this section of efficiency
