What are microbial fertilizers? What characteristics do microbial fertilizers have? We ask knowledgeable readers to help explainMicrobial fertilizers refer to specific products that contain living microorganisms and, through the specific action of those microorganisms, provide nutrients to plants and regulate plant growth. When applied in agricultural production, they can achieve specific fertilizer benefits and can serve as a beneficial supplement to chemical fertilizers. Zhongdi.com has compiled the advantages of microbial fertilizers, listed below for readers' reference.
Advantage one,Microbial fertilizers can improve soil fertility; for example: various free-living, associative or symbiotic nitrogen-fixing microbial fertilizers can all increase the source of nitrogen in the soil; microorganisms with phosphorus- and potassium-dissolving functions can secrete a variety of organic acids, and through chelation these organic acids can promote the release of insoluble phosphorus and locked-up potassium; rhizosphere microorganisms can also secrete some inducers to increase soil enzyme activity, which is beneficial to the transformation of nutrients in the rhizosphere soil and facilitates the absorption and utilization of nutrients by plants.
Advantage two,Microbial fertilizers can help crops absorb nutrients. Rhizobium fertilizer is an important type of microbial fertilizer. It can invade the roots of leguminous plants and form root nodules on the roots. The root nodules convert nitrogen in the air into ammonia to supply crop nutrition.
Mycorrhizae have the most obvious effect on phosphorus absorption, and also strengthen the absorption of elements in the soil that are poorly active and slow to move, such as zinc, copper and calcium.
Advantage three,Microbial fertilizers can effectively enhance plants' disease resistance and stress resistance. After some microbial fertilizers are applied to the soil, they can grow and multiply in large numbers at crop roots and become dominant bacteria in the crop rhizosphere. The shielding effect they produce helps inhibit the proliferation of pathogenic microorganisms and enhances the disease resistance of the plants. After some microbial fertilizers, such as mycorrhizal fungi, are applied to the soil, the hyphae that multiply in large numbers at crop roots not only benefit the crops' absorption of nutrient elements, but can also increase water absorption, thereby improving the crops' drought resistance.
