Agricultural microbial agent

After specific microorganisms and effective bacteria are industrially produced and propagated, and then porous substances such as peat and vermiculite are used as the fermentation broth to attach and adsorb bacteria, it is called microbial agent.
This kind of agricultural microbial fertilizer can not only improve the soil and restore soil fertility directly or indirectly, but also prevent soil-borne diseases, maintain the balance of microorganisms in roots and degrade harmful substances. Special microbial fertilizer for agriculture can effectively increase crop yield, improve the quality of agricultural products, reduce the amount of chemical fertilizer, reduce the cost, improve soil and protect the ecological environment.
