First of all, organic fertilizers are rich in various organic substances, such as cellulose, hemicellulose, lignin, protein, etc., which provide a rich food source for soil microorganisms under the decomposition of microorganisms. At the same time, minerals such as nitrogen, phosphorus and potassium in organic fertilizers are also effectively released, providing a lasting nutrient supply for plants.

Secondly, the microbial flora in organic fertilizers provides a good biological environment for the soil. These microbial flora not only help decompose organic matter, but also improve soil permeability and water retention, which is conducive to the stability of soil structure. At the same time, these microbial flora can also decompose heavy metals in the soil, reduce pollution, and protect the environment.

In addition, the use of organic fertilizers also promotes the interaction between different types of microorganisms in the soil. Different microorganisms grow together in competition and cooperation, forming a complex microbial ecosystem. This ecosystem is conducive to the recycling and utilization of various nutrients in the soil and improves the productivity of the soil.
