Do you know what microbial inoculants do to soil

The fertilizer effect of microbial inoculants lasts a long time, can reduce the amount of fertilizer applied, and it itself. Applying large amounts of chemical fertilizers and pesticides makes the soil polluted to different degrees and produces certain toxicity. Crops grown in contaminated soil, in addition to causing growth obstacles, their products can also pose a hazard to humans. The elimination of soil pollution is an important matter in environmental governance.

The common characteristics of saline-alkali land are low content of organic matter, poor physical and chemical properties of soil, more Yin and cation harmful to crop growth, low soil fertility, and difficult crop seedling promotion. Saline-alkali land is not easy to sprout seedlings, the general principle of fertilization is to increase the application of compound microbial fertilizer and bio-organic fertilizer, and appropriate control of fertilizer application. Base fertilizer should be applied more bio-organic fertilizer with high organic matter content, reduce the amount of fertilizer applied, and the fertilizer should be not close to the seed as far as possible, so as not to increase the concentration of soil solution and affect germination. Topdressing according to the situation, avoid excessive. In places where conditions exist, a large number of straw returning to the field, planting saline-alkali resistant green fertilizer and other methods can be used to reduce the harm of salt and alkali to crops.

Clay soil generally contains organic and inorganic colloid, soil fertilizer retention ability is strong, nutrients are not easy to lose. However, the clay fertilizer is slow, the effect of fertilization is also slow, the soil "old seedlings do not send small seedlings", the fertilizer effect is slow and long, the soil is compact, the permeability is poor, and the crops are difficult to root. This soil is applied with composite microbial fertilizers and bio-organic fertilizers, which increase permeability and improve fertilizer and water retention capacity through rich organic matter and beneficial microbial activities. Such soil properties are cloudy, such as the application of a small amount of undecomposed horse manure combined with complex microbial fertilizers and bio-organic fertilizers, the effect will be good.

A large amount of bio-organic fertilizer should be applied to the sandy land to increase the content of soil organic matter and improve the capacity of fertilizer preservation. Due to the good ventilation condition of sand soil, warm soil, organic matter is easy to decompose, the application of incomplete decomposed organic fertilizer is less affected than clay soil. Barren green fertilizer can be planted in areas where conditions permit to improve soil physical and chemical properties.

After the application of microbial inoculants into the soil, the beneficial microorganisms multiply rapidly in the soil and produce a variety of metabolites that are beneficial to crops. These metabolites can stimulate or regulate the growth of crops, make crops robust, and achieve the purpose of increasing production. It not only provides NPK and medium and trace elements needed for crop growth, but also provides organic matter and beneficial microbial active bacteria for crops. In addition, some strains of microbial bacteria can also secrete some stimulant vitamins to stimulate the growth of crops, so that crops are robust and nutritional conditions are improved.
