Are there any benefits to soil using microbial agents?

The fertilizer effect of microbial bacteria has a long duration, which can reduce the amount of chemical fertilizer applied, and it is non-toxic and harmless. A large number of fertilizers and pesticides pollute the soil to varying degrees and produce certain toxicity. Crops grown in contaminated soil can not only cause growth barriers, but also harm the human body. Eliminating soil pollution is an important part of environmental governance.

The commonalities of saline-alkali land are low organic matter content, poor soil physical and chemical properties, toxic ions harmful to crop growth, low soil fertility, and crops are not easy to promote seedlings. It is not easy to develop seedlings in saline-alkali land, and the general principle of fertilization is to increase the application of compound microbial fertilizers and bio-organic fertilizers, and appropriately control the application of chemical fertilizers. The base fertilizer should be applied more bio-organic fertilizer with high organic matter content, reduce the amount of chemical fertilizer, and the chemical fertilizer should not be close to the seed as much as possible, so as not to increase the concentration of the soil solution and affect germination. Topdressing according to the situation to avoid overdose. When conditions permit, a large amount of straw can be used to return to the field and plant a saline-tolerant green fertilizer to reduce the harm of salinity to crops.

Clay soil generally contains organic matter, more inorganic colloids, strong soil fertilizer protection ability, nutrients are not easy to lose. However, the fertilizer supply of clay is slow, and the effect is slow after fertilization. This soil old seedling is not a small seedling, the fertilizer effect is slow and growing, the soil is tight, the permeability is poor, and the crop root is difficult. This soil uses compound microbial fertilizers and bio-organic fertilizers, which improve permeability and improve fertilizer and water protection through abundant organic matter and beneficial microbial activity. This soil is yin in nature, such as a small amount of immature horse manure with compound microbial fertilizers and bio-organic fertilizers, the effect is better.

Bio-organic fertilizer should be increased on sandy soil, the content of soil organic matter should be improved, and the ability of fertilizer protection should be improved. Due to the good ventilation of the sandy soil, the warm soil, and the easy decomposition of organic matter, the application of organic fertilizer that is not completely decomposed is less affected than the clay surface. Poor green fertilizers can be planted in areas where conditions permit to improve the physical and chemical properties of the soil.

When microbial agents are applied to the soil, beneficial microorganisms multiply rapidly in the soil, producing various metabolites that are beneficial to crops. These metabolites can stimulate or regulate the growth of crops, making crops strong and achieving the purpose of increasing yields. It not only provides the NPK and medium trace elements needed for crop growth, but also provides crops with organic matter and beneficial microbial active bacteria. In addition, some bacteria in microbial agents can also secrete some irritating vitamins to stimulate the growth of crops, make crops strong, and improve nutritional status.
