Soil microbial fertilizer
1. Soil microorganisms can form soil structure
Soil is not a simple combination of simple soil particles and chemical fertilizers. As an active component of soil, soil microbes contribute to soil particles through the exchange of oxygen and carbon dioxide in metabolic activities and the secretion of organic acids in their own lives. The formation of a large agglomerate structure eventually leads to the formation of a true soil. The fauna composition, biomass and life activities of soil microbes are closely related to soil formation and development.
2. The most significant effect of soil microbes is the decomposition of organic matter.
The most significant effect of soil microbes is the decomposition of organic matter, such as the residual roots of crops and the organic fertilizer applied to the soil. Only through the action of soil microbes can it decompose and decompose, releasing nutrients for crop utilization and forming humus. Improve soil structure and tillage.
Then, soil microbes can also decompose minerals, and the metabolites of soil microbes can promote the dissolution of poorly soluble substances in the soil. For example, phosphorus bacteria can decompose phosphorus in phosphate rock, and potassium bacteria can decompose potassium in potassium ore to benefit crops and improve soil fertility. In addition, the decomposition and utilization of urea is also inseparable from soil microorganisms. These soil microbes are like fertilizer processing plants in the soil, which process the mineral fertilizer in the soil into a form that the crop can absorb.
3. Soil microorganisms also have nitrogen fixation
Nitrogen accounts for 4/5 of the air composition, but plants cannot be directly used. Some microorganisms can convert nitrogen in the air into fixed nitrogen nitrides that plants can use by means of their nitrogen fixation. With such soil microorganisms, it is equivalent to soil. I have my own nitrogen fertilizer production workshop.
Soil microorganisms living around the roots of plants can also regulate plant growth. Plant symbiotic microorganisms such as rhizobium, mycorrhiza and fungi can directly supply nutrients, organic acids, amino acids and vitamins of nitrogen, phosphorus and other mineral elements. Various organic nutrients such as auxin promote the growth of plants. Soil microbes are closely related to plant root nutrition.
4. There are mutual benefits between various microorganisms, and they are also mutually hostile.
There are some antibiotic microorganisms in the soil, they can secrete antibiotics and inhibit the reproduction of pathogenic microorganisms, so as to prevent and reduce the harm of pathogenic microorganisms in the soil to crops. Therefore, microorganisms in the soil actually have disadvantages, such as pathogenic microorganisms.
5. Soil microorganisms can also explain the harmful substances remaining in the soil.
Microorganisms can also degrade organic pesticides, municipal waste and factory waste in the soil. Microorganisms break them down into low-harming or even harmless substances, reducing the risk of residual poisoning. Of course, all of these functions are performed by microorganisms of different populations, and the realization of each function requires a large number of microorganisms to work together.
6. The future prospects of soil microbes cannot be estimated
Nowadays, there are a large number of examples of application of microorganisms in medical and health care, industrial and agricultural production. Take the microbes in the soil. By developing and screening effective strains and cultivating high-efficiency strains, we can repair contaminated soil, produce bacterial fertilizer, biological pesticides, and so on.
Therefore, bacterial fertilizer is also a fertilizer with future development prospects!
