Efficacy of Poultry Feather Decomposition by Native Isolates of Bacillus Sp. And it's Impact on Mineralization.

The study was conducted in preparation of feather compost, characterization and effect of feather compost in the fields. During the study period Bacillus subtillus was used to degrade the feather material. Initially, decomposed soil samples were collected in the poultry feather dumping places. Bacillus subtillus was isolated as best native species and used to degrade the feather material. The degradation of chicken feathers was observed through morphological level changes. During the feather degradation for temperature were recorded on 20 th day (42.1°C) and decreased trend was observed up to 40 th day (25°C) respectively. The high moisture content on 15 th day (41%) and decreased moisture content in feather compost in 40 day (29%). The maximum available nutrient content was estimated at after 40 days of inoculation of FDS 15 such as 88mg, 9.10mg and 72.0 mg per kg of N, P and K respectively under sand 2 kg + 30 % of cleaned feather (T1). The decomposition of feather was faster in the treatment which inoculated FDS 15 except control which might be due to drastic multiplication FDS15 bacteria. The minimum available nutrient of 19mg, 5.85mg and 56.5mg in N, P and K respectively recorded under control (sand alone). The results of mineralization estimate showed that FDS15 Bacillus subtilis was increase the decomposition process of feather even increase the quantity of substrate (feather) which leads to convert the higher content of nutrients in the soil. Generally, the pH and EC of the substrate were on par with treatments. It indicates that the inclusion of the organisms in poultry waste compost was successful in producing an odourless, pathogen free product with complete biological degradation waste in 40 days of the feather. The application of this system may improve the rapid disposal of poultry waste as well as the public and environmental health in the region.
