Most organic fertilizers have the same effect on the application of microorganisms, that is, long-term application of organic fertilizer or organic fertilizer combined with chemical fertilizer can significantly increase the number of bacteria, fungi and actinomycetes in the soil. The reason for applying organic fertilizer to increase soil microbes is that organic fertilizer provides enough carbon, nitrogen and inorganic salts to promote the growth and reproduction of soil microorganisms. The increase in microbial activity in turn promotes an increase in humus. In the soil, the mineralization process of organic matter releases a large amount of nutrients and energy, further stimulating microbial activity.
