Composting refers to a biochemical process that uses microorganisms that are widely present in nature to controllably promote the conversion of degradable organic matter in solid waste into stable humus. Composting is the process of producing organic fertilizer. It contains rich nutrients and has a long and stable fertilizer effect. At the same time, it promotes the formation of soil solid grain structure and can increase the soil’s ability to retain water, heat, air, and fertilizer. The mixed-use of chemical fertilizers can also make up for the single nutrient content of chemical fertilizers. Long-term single use of chemical fertilizers will harden the soil and reduce the performance of water and fertilizer retention. Composting is the use of various organic wastes (such as crop straw, weeds, leaves, peat, organic household waste, food waste, sludge, human and animal manure, distiller grains, fungus chaff, and other wastes, etc.) as the main raw materials. Compost decomposed organic fertilizer.
Composting machinery for sale:
Composting is inseparable from the application of Composting machinery. Our company has a variety of Composting machinery for sale. Composting equipment is the main part of composting. Aerobic composting is often used in the composting process. The composting process includes Fermentation Tank, through fermentation, and stack fermentation. These three composting methods all adopt aerobic composting. Trough fermentation requires wheel turning and throwing machine, and stack fermentation requires a Compost turner.
Aerobic composting is carried out under aerobic conditions with the help of aerobic microorganisms. During the composting process, the soluble organic matter in the organic waste is absorbed by the microorganisms through the cell walls and cell membranes of the microorganisms; the solid and colloidal organic matter first attaches to the body of the microorganism and then decomposes into it under the action of the extracellular enzymes secreted by the microorganisms. The soluble substance penetrates into the cell. Microorganisms oxidize part of the absorbed organic matter into simple inorganic matter through their own life activities-redox and biosynthesis processes, and release the energy required for the growth and activity of microorganisms, and convert another part of the organic matter into new cellular materials. The microorganisms are allowed to grow and multiply to produce more organisms, and the remaining organic matter that has not been degraded is partially converted into humus. Finally, the organic waste is mineralized and humified, and the high temperature (60-70°C) generated during the accumulation is used to kill the germs, insect eggs, and weed seeds in the raw materials to achieve the goal of harmlessness. . Therefore, in order to obtain high-quality compost, in the process of composting, doing everything possible to create good conditions for the life activities of microorganisms is the key to accelerating compost maturity and improving fertilizer efficiency.
Compost raw materials:
1. Basic materials are substances that are not easy to decompose, such as various crop straws, weeds, fallen leaves, vines, peat, garbage, vegetable garbage, etc.
2. Substances that promote decomposition are generally those with high nitrogen content and high-temperature fiber decomposition bacteria, such as human and animal urine, sewage, silkworm sand, horse manure, sheep dung, old compost, plant ash, lime, and so on.
3. Adding a small amount of peat, fine soil and a small amount of superphosphate or phosphate rock powder to the material with strong absorption during the accumulation process can prevent and reduce the volatilization of ammonia and improve the fertilizer efficiency of compost.
