Reasons why organic fertilizer must be fermented:
1. The spread of pests and diseases. Unfermented feces contain a large number of harmful microorganisms such as Escherichia coli and nematodes. Direct application will lead to the spread of pests and diseases, making crops susceptible to disease, polluting the environment, and having adverse effects on human health.
2. Burning seedlings. Once the unfermented feces have fermentation conditions in the soil, the microorganisms will be active, and the heat generated by the fermentation will affect plant growth or cause seedling burning.
3. Toxic gas hazards. When fermenting, feces will produce sulfur dioxide, ammonia and other gases that are harmful to plants and the environment, causing damage to crops, and the gas will be emitted into the air to pollute the atmospheric environment. The
organic fertilizer composting turning machine has the function of air purification, helping to purify the factory environment.
4. Causing soil hypoxia. Raw fecal organic matter will consume a lot of oxygen in the soil during the decomposition process.
5. Pollute the environment. After being blown by wind and rain, the fertilizer effect of raw manure is lost, polluting rivers and soil, and the odor produced also contains harmful substances.
6. Inconvenient transportation. Untreated feces that are directly used are large in size, smelly, and inconvenient to transport and use.
Fermentation principle of organic fertilizer:
The raw materials of organic fertilizer contain a large number of bacteria and fungi. When the temperature, moisture, oxygen content and other conditions are suitable, these microorganisms will multiply in large numbers and decompose the organic matter in the raw materials. The high-temperature aerobic fermentation process of the raw materials is actually the process of microbial fermentation. Insoluble macromolecular organic matter first attaches to the outside of the microorganism, and the extracellular enzymes secreted by the microorganism decompose it into soluble small molecules, and then it is sent into the microbial cells for use. The shape of the pile matrix is complex, and it can only be used by microorganisms if it is decomposed into a simple form.
