Importance of microbial organic fertilizer to soil environment

With the progress of the times, people gradually realize the importance of soil environment, people began to invest a lot in organic fertilizer, the bio organic fertilizer production increased greatly, using the decomposition of microorganisms in organic fertilizer to improve the soil environment.
Soil pollution can be divided into inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, etc.; organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, etc. The basic principle of microbial fertilizer for soil remediation is that under appropriate conditions, such as water, temperature, pH value, etc., the microbial community in the fertilizer and the original beneficial microorganisms in the soil jointly form the dominant microbial community, promote the benign circulation of carbon, nitrogen, oxygen and other elements in the soil ecosystem, so as to repair the soil ecosystem and make the ecosystem reach a new stable balance.

The remediation mechanism of microbial fertilizer for inorganic pollutants is that after the microbial fertilizer enters the soil ecosystem, aerobic bacteria, anaerobic bacteria and other microbial probiotics reduce the soil acidity and improve the pH value of the soil through their own biological reaction, so as to reduce the toxicity of harmful heavy metals in the soil; at the same time, the microbial bacteria in the fertilizer can fix heavy metals and promote the activity of heavy metals in the soil. Metal becomes organic combination, forming filter layer and isolation layer, reducing the absorption of heavy metals in the soil by crops, so as to avoid the indirect absorption of harmful substances such as heavy metals in the soil or their decomposition products by the human body and damage the health of the body.
The function of microbial fertilizer in the remediation of organic pollutants such as pesticides in soil is to reduce the number of pest control, reduce the use of pesticides, so as to reduce pesticide residues in crops. On the one hand, microbial fertilizer can change the microflora of soil tillage layer, form dominant colonies around the roots of crops, so as to strongly inhibit the propagation of pathogenic bacteria and reduce the occurrence of diseases and insect pests; on the other hand, during the process of microbial life activities, it can produce a variety of substances, such as hormones, humic acids and antibiotics, which can stimulate the growth of crops and enhance the self-sufficiency of crops. Body disease resistance.
