How to Process Chicken Manure into Organic Fertilizer: During the feeding process, chicken cannot digest and absorb the feed completely, which leads to about 40% – 70% nutrients expelled from body, therefore, fowl manure is the best type manure among poultry dung and livestock manure to use as fertilizer . Compared with horse, cow or steer manure, organic fertilizer made from chicken dung can provide more Nitrogen, Phosphorus and Potassium to soil and plants. According to the testing of relevant department, fresh chicken manure contains about 70% water content, 25.5% organic matter, 1.63% nitrogen, 1.54% phosphorus and 0.85% calcium, which makes chicken dung suitable to be used as raw materials of organic fertilizer production. Moreover, with high nitrogen content and relatively lower carbon content, it is necessary to add rice husk or straw to increase C/N ratio and reduce moisture when making chicken manure fertilizer. Meanwhile, people should also add humic acid to fix ammonia-nitrogen as ammonium humate, reducing nutrient loss and enhancing fertility and soil improvement during the process of fermentation. http://organicfertilizermachine.com/eco-solutions/how-to-process-chicken-manure-organic-fertilizer.html
