The application of biological bacterial fertilizer is to increase the soil "beneficial microorganisms", and the most significant effect of soil microorganisms is "decomposition of organic matter". In addition to beneficial microorganisms, there are also pathogenic bacteria and harmful bacteria in the soil. These harmful microorganisms will also use organic matter to reproduce in large quantities. In addition to causing crop diseases, it will also cause soil problems to become more serious. Therefore, the application of organic matter must be combined with beneficial microorganisms to fight pathogens to help crops and soil.
The relationship between organic matter and microorganisms is inseparable. For example, the residual roots and leaves of crops and organic fertilizers applied to the soil can only rot and decompose through the action of soil microorganisms, releasing nutrients for crop utilization, and forming humus to improve the structure and cultivation of the soil.
Soil microorganisms can decompose minerals. Metabolites of soil microorganisms can promote the dissolution of insoluble materials in the soil. For example, phosphorus bacteria can decompose phosphorus in phosphate ore, and potassium bacteria can decompose potassium in potassium ore, so as to facilitate crop absorption and improve soil fertility.
The effect of the combined use of biological bacterial fertilizer and organic fertilizer. Organic fertilizer provides organic matter, and bio-fertilizer provides beneficial microorganisms. In addition, organic matter is the food of microorganisms. The more organic matter in the soil, the better the microorganisms can live. In this way, the two are applied together to promote each other, which can improve loose soil, improve soil permeability and water retention, enhance root absorption capacity, and improve fertilizer utilization.
Inorganic fertilizers are used for indirect crop absorption through decomposition and transformation of organic matter in the soil. The increase of organic matter promotes the increase of soil activity and creates space for microorganisms to survive and reproduce. In turn, a large number of activities of biological bacteria have activated soil activity, forming a virtuous cycle that is very beneficial to the soil.
With the increase of organic matter, the stress resistance of crops will also increase, and at the same time, the invalid phosphorus and invalid potassium remaining in the soil will be changed to effective phosphorus and effective potassium for the crops to absorb and use. This is why the increased application of organic fertilizers and biological bacterial fertilizers can increase the efficiency of the use of chemical fertilizers, thereby reducing the use of chemical fertilizers and ensuring the health of the soil and food.
