The impact of composting on organic fertilizer is primarily reflected in the following aspects:
1. Improving organic fertilizer quality: During the composting process on the fertilizer produciton line, the total nitrogen content in the compost pile initially decreases and then increases, increasing by 28.07% to 48.51% compared to the initial level. The available phosphorus and available potassium contents increase by 8.77% to 200.00% and 66.14% to 385.55%, respectively. This demonstrates that composting can effectively increase the nutrient content and effectiveness of organic fertilizer, making it more effective.
2. Reducing the production of harmful gases: Uncomposted organic fertilizer produces harmful gases during decomposition. Composting, by controlling fermentation conditions, reduces these harmful gases and improves the safety of organic fertilizer.
3. Optimizing composting conditions: The compost temperature during the fermentation process can be summarized as a steady increase in the early stages, a moderately high temperature maintained in the middle, and a slow decrease in the later stages. A suitable temperature promotes microbial activity and accelerates the decomposition and transformation of organic matter. Appropriate humidity promotes normal microbial growth and metabolism, while also preventing the fermentation process from being affected by excessive or insufficient moisture.
4. Promotes Microbial Activity: The types and numbers of microorganisms in the fermentation compost turning machine fluctuate during production. Bacteria, fungi, and actinomycetes are the primary microorganisms involved in the composting process, playing important roles at different stages.
5. Shortens the Fermentation Cycle: Composting creates a suitable environment, promoting rapid microbial growth and activity, accelerating the decomposition of organic matter.
Improves Fermentation Efficiency: Proper composting conditions, such as an appropriate carbon-nitrogen ratio, moisture content, and aeration, can improve fermentation efficiency and enable organic fertilizer to reach maturity more quickly.
