| Research Abstract |
The characteristics of nitrogen transition and N_2O generation during the composting of cattle, swine and poultry manure were examined, and the adaptable range of the nitratation promotion process was quantified. Nitrite accumulated for a long period in swine manure composting. In the composting of cattle or poultry manure, however, remarkable nitrite accumulation was not observed. Therefore, the quantity of N_2O emission induced by nitrite accumulation was thought to be small in cattle and poultry manure composting, which indicates that nitratation promotion would not be proper for reducing N_2O emissions in these kinds of composting.
