Chicken manure is a high-quality organic fertilizer raw material, rich in nutrients and with long-lasting effects. However, fresh chicken manure contains pathogens and insect eggs and can easily burn roots. Therefore, it must undergo professional processing to become safe and compliant agricultural organic fertilizer. The production process of chicken manure organic fertilizer is standardized and simple to operate, mainly consisting of six core steps.
The first step is raw material pretreatment. After collecting fresh chicken manure, the moisture content is first adjusted. Fresh chicken manure has high moisture content and strong viscosity, so it needs to be mixed with auxiliary materials such as straw, sawdust, and rice husks to control the moisture content to around 55%. At the same time, impurities are removed, including stones and plastic debris, to ensure the purity of the raw materials and lay a good foundation for subsequent fermentation.
The second step is high-temperature composting and fermentation. This is the core of the production process. The mixed raw materials are piled into long strips, and a special fermentation agent is added to initiate aerobic fermentation. During fermentation, the temperature will rise to 60 to 70 degrees Celsius. This sustained high temperature effectively kills insect eggs, pathogens, and weed seeds in the chicken manure and completely removes odors. During the fermentation process, a compost turning machine is used regularly to turn the compost pile and provide oxygen, preventing the production of harmful substances through anaerobic fermentation. The entire fermentation process takes approximately 15 to 20 days.
The third step is aging and cooling. After initial fermentation, the material temperature is high, and the nutrients are not yet stable, requiring 7 to 10 days of aging. The material is spread out to cool naturally, further decomposing residual organic matter, stabilizing the fertilizer properties, preventing seedling burn later, and improving fertilizer safety.
The fourth step is crushing and screening. Aged fertilizer may clump. A crusher is used to break up the clumps, followed by screening to filter impurities and large, unfermented pieces, selecting fine and uniform organic fertilizer raw materials to ensure fertilizer quality and application effectiveness.
The fifth step is granulation and drying/cooling. Powdered fertilizer can be granulated into pellets using a granulator, facilitating storage and application. After granulation, the fertilizer is dried at a low temperature in a dryer to control its moisture content, and then naturally cooled to prevent nutrient loss due to high-temperature storage.
The final step is metering and packaging. After cooling, qualified organic fertilizer is metered, sealed, and packaged using automated equipment, ready for storage or sale. Chicken manure organic fertilizer processed through this entire process is odorless, pollution-free, and nutrient-balanced, making it widely applicable for fruit and vegetable cultivation and crop planting, improving soil quality and enhancing soil fertility.
