A by-product of poultry processing, feather waste is a protein biomass rich in peptides, amino acids, and valuable micro and macro minerals. The application of feather waste as soil fertilizer represents not only a sustainable feather disposal method, but may also represent an effective strategy to tackle environmental effluence. Feather waste has been found to elevate protein (0.78 ± 0.001 mg/g of dry wt), total carbohydrate (0.3 ± 0.002 mg/g of dry wt), total chlorophyll (1.52 ± 0.08 mg/g of dry wt), and proline (0.106 ± 0.001 mg/g of dry wt) contents of plants and wheat seeds. Such increases have been associated with considerably higher phenolic and flavonoid contents. Therefore, its application may promote and improve the agro-ecosystem, soil texture, and soil bio-ecology and enhance the production of plant or products rich in bioactive substances. In this study commercially usable feather fertilizer was developed by mixing the feather waste and fly ash, which increased its effectiveness and storage ability. Laboratory application showed significantly improved crop yields. Consequently, feather hydrolysates created through the microbial conversion of feather keratin may be utilized as a potential bioactive agricultural nitrogen input.
