1、 Improve soil and enhance soil fertility. After applying organic fertilizers to the soil, organic matter can effectively improve the physical and chemical conditions and biological characteristics of the soil, mature the soil, enhance the soils ability to retain and supply nutrients, and buffering capacity, creating favorable soil conditions for crop growth.

2、 Increase production and improve quality. Organic fertilizers contain abundant organic matter and various nutrients, providing nutrition for crops. After organic fertilizer decomposition, it provides energy and nutrients for soil microbial activity, promotes microbial activity, accelerates organic matter decomposition, and produces active substances that can promote crop growth and improve the quality of agricultural products.

3、 Improve the utilization rate of fertilizers. Organic fertilizers contain a lot of nutrients but have relatively low content and slow release, while chemical fertilizers have high nutrient content per unit, fewer components, and fast release. The reasonable combination of the two can complement each other, and 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, which is beneficial for crop absorption and improves fertilizer utilization efficiency.
