How to make solid organic materials into fertilizers?
With the development of economy and the improvement of people’s living standards, the discharge of solid waste is increasing day by day, and the solid waste treatment and disposal technology for the purpose of solid waste reduction, recycling and harmless is also in the process of diversified development. Among them, composting technology has become one of the key technologies for solid waste recycling.
In agricultural production, there are problems such as excessive application of chemical fertilizer and insufficient application of organic fertilizer, resulting in agricultural environmental pollution and poor quality of agricultural products. In the modern development of ecological agriculture, it is of great significance to make full use of the existing solid waste, especially the organic waste rich in organic matter and a certain amount of nitrogen, phosphorus, potassium and other nutrients to develop bio organic fertilizer technology.
The effect of organic fertilizer
1.1 to improve soil environment and fertility, the application of organic fertilizer can increase the content of soil organic matter and supplement the nutrients needed by plants. Humic acid is formed after the organic matter is decomposed by microorganism, which can improve the soil structure and increase the content of beneficial microorganisms in the soil. In addition, soil organic matter directly affects soil fertility, water retention, thermal insulation, buffering and aeration.
1.2 improve the soil micro ecological environment, give full play to the advantages of microorganisms. The bio organic fertilizer with functional bacteria contains some beneficial bacteria, such as nitrogen fixing bacteria, silicate bacteria, phosphate solubilizing microorganisms, photosynthetic bacteria and pseudomonas bacteria, which changes the structure of soil microecosystem, enhances the ability of nitrogen fixation, phosphorus solubilization, potassium release, etc., and can give full play to the advantages of various functional microorganisms crop rhizosphere bacteria balance, inhibit the series of pathogens, and then enhance the ability of crop resistance to pests.
