Pig manure is rich in nitrogen, phosphorus, potassium, and organic matter, making it a high-quality raw material for organic fertilizer. However, direct application without treatment can easily burn roots, breed pests and diseases, and pollute the environment. Utilizing organic fertilizer production lines and compost turners, and employing scientific composting technology, harmless and resource-efficient utilization can be achieved, producing high-quality organic fertilizer efficiently.
Raw Material Preparation. Fresh pig manure has a high moisture content and is very sticky. Straw, sawdust, and other auxiliary materials need to be added to adjust the carbon-to-nitrogen ratio, controlling the moisture content to 55%~65%. Large-scale composting can be achieved through raw material crushing and proportioning on the organic fertilizer production line, ensuring uniform mixing and laying the foundation for fermentation.
Composting and Fermentation. The prepared raw materials are piled into long strips. Professional temperature control equipment assists in heating, initially raising the temperature to 55~65℃, which kills pathogens, insect eggs, and weed seeds, achieving harmless standards. No sealing is required; natural ventilation is ensured.
Turning and managing the compost pile is crucial. Organic fertilizer compost turning machines can replace manual turning, ensuring sufficient oxygen in the pile, preventing anaerobic fermentation and unpleasant odors, promoting even fermentation, accelerating the process, reducing labor costs, and improving efficiency.
Finally, the degree of decomposition is assessed. Fully decomposed pig manure compost is dark brown, loose in texture, and odorless, and can be further processed into finished products through an organic fertilizer production line. This technology addresses livestock pollution, provides high-quality fertilizer, and is a practical solution for integrated crop and livestock farming.
