| dc.description | Nitrogen (N) losses during composting reduce the value of the end product as a fertilizer. Nitrogen is lost during composting mainly by ammonia (NH3) volatilization in the thermophilic phase. We used three bench-scale aerobic bioreactors with a controlled temperature difference (CDT) system as an experimental approach to investigate the pattern of N losses during composting. N2O peak emission occurred much earlier (7h) than NH3 volatilization (48-60h) during the thermophilic phase (~55°C) of bench-scale composting. The NH3 volatilization peak rate occurred following the greater biological activity (O2 consumed/CO2 evolved) at 40°C which could coincide with greater ammonification, but immobilization of NH4+/NH3 also occurs at this point affecting NH3 volatilization. Differences in temperature curves and accumulated NH3-N were related to the biological activity in each vessel. Therefore, O2 consumed/CO2 evolved measurements must be part of the evaluation of composting in further studies for comparisons of techniques to reduce NH3 volatilization | pt_BR |
