Function of Organic Fertilizer

Organic fertilizer contains not only a large number of elements and trace elements necessary for plants, but also rich organic nutrients. Organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizers in agricultural production is mainly reflected in the following aspects:

First, improve soil and fertility. After the organic fertilizer is applied to the soil, the organic matter can effectively improve the physical and chemical properties and biological characteristics of the soil, mature the soil, enhance the fertility and buffer capacity of the soil, and create good soil conditions for the growth of the crop.

Second, increase production and improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrients for crops. After the organic fertilizer is decomposed, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that promote crop growth and improve the quality of agricultural products.

Third, improve the utilization rate of fertilizers. Organic fertilizers contain much nutrients but relatively low levels and slow release. Fertilizers have high nutrient content, low composition and fast release. The two are rationally combined and applied, complement each other, and the organic acid produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. There is mutual promotion of organic fertilizer and chemical fertilizer, which is conducive to crop absorption and improve fertilizer utilization.
