What is bio fertilizer used for? Thank you!

Because biological fertilizer contains a large number of biological agents, with the help of biological bacterial activities, it can not only improve the structure of the soil and increase the content of various elements in it, but also bring the effects of potassium dissolving, phosphorus release and nitrogen fixation. After the biological bacteria fertilizer is applied to the soil, the biological bacteria proliferate quickly, forming a group advantage to decompose the nitrogen, phosphorus and potassium that are fixed in the soil and cannot be absorbed and utilized by plants, and fix the free nitrogen in the air for plants to absorb and utilize. Biological fertilizer can also help crops to take root, emerge and mature earlier, and will make crops resistant to stress, which can effectively resist disease, drought and lodging.

Biological fertilizer is a living fertilizer, and its role is mainly completed by the life activities of a large number of beneficial microorganisms contained in it. Only when these beneficial microorganisms are in vigorous reproduction and metabolism can the transformation of substances and beneficial metabolites continue to be formed. Therefore, the types of beneficial microorganisms in microbial fertilizers and whether their life activities are vigorous are the basis of their effectiveness, unlike other fertilizers based on the form and amount of major elements such as nitrogen, phosphorus, and potassium.

Because microbial fertilizer is a living preparation, its fertilizer efficiency is closely related to the number and intensity of live bacteria and the surrounding environmental conditions, including temperature, moisture, pH, nutritional conditions and the rejection of indigenous microorganisms in the soil.

1. Biofertilizer is also known as biological fertilizer, bacterial fertilizer, bacterial fertilizer or inoculant, etc., but most people are used to calling it bacterial fertilizer. To be precise, biofertilizer is a fungus rather than a fertilizer, because it itself does not contain the nutrients needed for plant growth and development, but only contains a large number of microorganisms, which improve the nutritional conditions of crops through the life activities of microorganisms in the soil.

2. Improve the fertility of soil before repentance. This is the main effect of microbial fertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase the nitrogen content in the soil; A variety of microorganisms that decompose phosphate and potassium ore precursors, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in Bixian Qing soil, so that the insoluble phosphorus and potassium in them can be effective.

3. Manufacture and assist crops to absorb nutrients. After the application of some bacterial fertilizers, due to the activity of microorganisms, it can not only increase the effective nutrients of the soil, but also produce a variety of hormones and various vitamins, thereby promoting the growth of crops.

4. Enhance the stress resistance of plants. After inoculation, some microbial fertilizer strains become the dominant bacteria in the rhizosphere of crops due to their large growth and multiplication in crop roots, and they can secrete antifungal and bacterial antibiotics, thereby inhibiting the growth of a variety of pathogens.
