Abstract

The process of converting poultry waste into organic fertilizer is the best option, but the challenge in treating nitrogenous waste is the easy loss of nitrogen and the increase in methane emissions.  Thus, the aim of this study was to determine the best mixing ratio of biochar )BC( for the production of organic fertilizer and to test the degree of maturity and stability of the produced fertilizer through maturity and stability tests. Addition of BC to the poultry litter (PL) was very beneficial, as it gave several initial indications of the possibility of producing good organic fertilizer.  BC was added to the PL in proportions of 0%, 5%, 10%, and 20% by weight to produce compost using cylindrical bioreactors.  The results showed that the addition of 10-20% of biochar to poultry litter achieved the highest average temperature (62.2, and 67.5 °C, respectively) after 48 hours from the start of operation. The decrease of percentage of organic matter, volatile solids, and ash during the the active stage are indicators of increased microbial activity and analysis of organic matter. The maturity and stability tests (Solvita index and Dewar's test) as well as the phytotoxicity test (germination index) proved that the compost contains 10-20% biochar, is mature, and stable compost with low ammonia.  Therefore, adding biochar to the poultry litter leads to improve the homogeneity and building the mixture and stimulating the microbial activity in the compost mixture, and this has good economic effects in terms of accelerating the process of compost production.
