Feather meal is used in formulated animal feed and in organic fertilizer. Worldwide, more than 25 billion chickens are used for human consumption. Feather meal is made through a process called rendering. Steam pressure cookers with temperatures over 140Â°C are used to cook and sterilize the feathers.
Abstract. Plant nutrition in organic farming is based entirely on decomposition of organic materials, and release of excess N superfluous to the microbial population. Feather meal (FM), a by-product of the poultry processing industry, which contains 15% N as non-soluble keratin, is a potential organic N fertilizer. The objective of this study was to determine the rate of N mineralization and changes in microbial activity following the application of FM to soil.
