Heterogeneity of biochar amendment to improve the carbon and nitrogen sequestration through reduce the greenhouse gases emissions during sewage sludge composting
Biochar additions increased the dehydrogenase activity during composting. Biochar have a potential impact on reduction of N losses and gaseous emissions. Biochar amendments shorten the thermophilic phase period. Biochar additions increased CO2 emission and reduce the ammonia losses. Biochar additions have significant correlation with carbon and nitrogen losses.
