The role of organic fertilizer in agricultural production is mainly reflected in the following aspects:

First, improve the soil, fertility. After organic fertilizer is applied into the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the soil's ability to retain and supply fertilizer and buffer, and create good soil conditions for the growth of crops.

Increase output and improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrients for crops. After decomposition of organic manure, it can provide energy and nutrients for soil microbial activities, promote microbial activities, accelerate organic matter decomposition, and produce active substances that can promote the growth of crops and improve the quality of agricultural products.

Third, improve the utilization rate of fertilizer. Organic fertilizer contains more nutrients but lower relative content, release is slow, while chemical fertilizer unit nutrient content is high, less components, release fast. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizers. Organic fertilizer and chemical fertilizer promote each other, conducive to crop absorption, improve the utilization rate of fertilizer.
