Microbial fertilizer is a product that causes a specific fertilizer effect on crops by the life activity of microorganisms, and is a type of fertilizer used in agricultural production. And how do these tiny organisms work in the soil?
The effects of microbial fertilizers are mainly related to the source and effectiveness of nutrients, or to crop absorption of nutrients, water and disease resistance, and are summarized as follows.
1.
Fertilization of the ground, which is one of the main efficacy of microbial fertilizers. For example, a variety of autotrophic and symbiotic nitrogen-fixing microorganisms can increase the source of nitrogen in the soil; the application of a variety of phosphorus and potassium solubilizing microorganisms can break down the insoluble phosphorus and potassium in the soil so that it can be absorbed and used by crops. Microbial fertilizer can be applied to the soil, it can quickly reproduce and form a powerful probiotic colony, which fundamentally improves the ecological structure around the soil and root system, makes the soil loosened and airy after years of using chemical fertilizers, absorbs nitrogen in the air and forms "ecological nitrogen fertilizer", activates the invalid dead phosphorus and dead potassium deposited in the soil for years, and allows the plant root system to absorb it. The dead phosphorus and potassium deposited in the soil for many years will be activated and absorbed by the plant roots.
2.
Enhancing resistance. Microbial fertilizers can reduce crop diseases in addition to the yield and income increasing effects of traditional fertilizers. There are three main reasons for this.
First, the beneficial
microorganisms in the fertilizer grow and multiply, forming a dominant population within the inter-root soil microbiological system of the crop, inhibiting the growth and reproduction of other harmful microorganisms, and even producing antagonistic effects on some harmful pathogenic bacteria, reducing the chances of harm from harmful microorganisms.
Second, beneficial microorganisms in the process of growth and reproduction to the crop inter-root soil microcosm system within the secretion of a variety of metabolites, these metabolites can stimulate crop growth and improve the ability of crops to resist adverse conditions.
Third, when plants are subjected to adversities such as disease, frost, drought and aging, the application of microbial fertilizers contains strains that can induce crops to produce superoxide dismutase, eliminating free radicals generated by adversity, thereby improving the resistance of crops and reducing disease.
3.
Improve the quality of early maturity and high yield. Microbial fertilizer can stimulate the fixed potassium, calcium, zinc and other micronutrients in the soil. These elements can supply crops microbial fertilizer can produce phytohormone-like substances to stimulate crop growth. Many microorganisms used as microbial fertilizers can also produce phytohormone-like substances, which can stimulate and regulate crop growth and make plants grow strong and improve their nutritional status. Generally, it can increase the yield of cash crops by more than 30% and field crops by 7-10% or more.
Scientists have discovered through research that microorganisms have the miraculous function of holding nitrogen in place and can convert free state nitrogen in the air into effective state nitrogen that can be absorbed and used by crops. In addition, the phosphorus and potassium bacteria in
microorganisms can break down the fixed phosphorus and potassium elements in the soil and release them for crop use. Those effective bacteria that multiply rapidly can also stimulate the growth of crops and act as disease prevention. As a result, scientists have selected and bred beneficial microorganisms that can be cultivated artificially, and produced live microbial products through industrial fermentation, which can be directly used in agricultural production. Microbial fertilizer is a type of product that promotes crop growth or yield increase or quality improvement by using microbial life activities to cause specific fertilizer effects on crops.
