Poultry manure is a nutrient-rich waste that can be efficiently transformed into high-quality organic fertilizer. However, due to its high moisture, pathogens, and odor, proper treatment is essential before application. For commercial and sustainable fertilizer manufacturing, three techniques stand out for treating poultry manure effectively: composting, dehydration, and granulation.
1. Aerobic Composting – Biological Decomposition at Its Best
Composting is the most common and eco-friendly method for treating poultry manure. The process involves piling the manure in windrows or using in-vessel or groove-type composting machines to maintain aerobic conditions. By regularly turning the material and monitoring temperature and moisture, pathogens are killed and odor is reduced. Within 15–25 days, poultry manure can be converted into mature compost. The addition of carbon-rich materials like straw or sawdust helps balance the C/N ratio, accelerating the poultry poop decomposition process.
2. Solid-Liquid Separation – The First Step for Moisture Control
Fresh poultry manure typically contains more than 70% moisture, making it unsuitable for direct composting or granulating. A manure dewatering machine (screw press separator) is used to separate solids from liquids. This step reduces moisture to around 30–40%, making the solid fraction easier to compost or pelletize. The liquid effluent can be further treated or used for biogas production. Dewatering improves composting efficiency and prevents leaching of nutrients.
3. Granulation – Turning Treated Manure into Marketable Fertilizer Pellets
Once poultry manure is composted and moisture-adjusted, the next step is poultry manure fertilizer granulation. Using machines like the disc granulator, rotary drum granulator, or new type organic fertilizer granulator, the fine compost powder is shaped into round pellets. These pellets are easier to handle, store, and apply. Granulated fertilizer also offers controlled nutrient release and reduces nutrient loss due to wind or water erosion. More details.
Conclusion
Efficient poultry manure treatment not only reduces environmental risks but also unlocks economic value through organic fertilizer production. By integrating aerobic composting, solid-liquid separation, and granulation, poultry farms and fertilizer producers can create sustainable, profitable solutions from agricultural waste. These top three techniques ensure hygienic, nutrient-rich, and marketable fertilizer products suitable for both large-scale and small-scale operations.
