Space, increase soil biological activity, enhance the release of available nutrients, is conducive to root growth, and improve plant resistance.
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 also use organic matter to multiply in large quantities. As a result, in addition to causing crop diseases, soil problems become more serious. Therefore, the application of organic matter must be combined with beneficial microorganisms to fight against pathogens to help crops and soil.
1. The relationship between organic matter and microorganisms is inseparable. For example, the residual roots of crops and the organic fertilizers applied to the soil can only be decomposed and decomposed by the action of soil microbes, releasing nutrients for crop utilization, forming humus and improving soil structure and tillage.
2. Soil microorganisms can also break down minerals. Metabolites of soil microbes 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, 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. The main manifestation of the combined use of biological bacterial fertilizer and organic fertilizer. Organic fertilizer provides organic matter, biological fertilizer provides beneficial microorganisms, and 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 can be applied together, promote each other, learn from each other, and use each other to improve the loose soil, improve the permeability and water retention of the soil, enhance the absorption capacity of the root system, increase the fertilizer utilization rate, and thereby reduce the application amount of the fertilizer.
4. Inorganic fertilizer is absorbed and transformed by the organic matter in the soil and indirectly for crop absorption. The increase of organic matter promotes the increase of soil activity, creating a space for living activities and reproduction of microorganisms. In turn, a large number of activities of biological bacteria activate soil activity and form a virtuous cycle that is very favorable to the soil.
In short, with the increase of organic matter, the resilience of crops will also increase, and the ineffective phosphorus and ineffective potassium remaining in the soil will be converted into effective phosphorus and effective potassium for crop absorption and utilization, which is why organic application is added. Fertilizers and bio-fertilizers can increase the efficiency of chemical fertilizer use, thereby reducing the amount of fertilizer used, and ultimately soil health and food health are guaranteed.
