pplied nitrogen present in the sludge or manure) were taken into
consideration for the GHG calculation [30,32]. CH4 emission was
found to be negligible and also depends on the soil condition (submerged
or anaerobic condition induces CH4 production) and has
not been taken into consideration for GHG calculation [32]. For
case B scenarios, carbon sequestration from applied
sludge/biomass, biochar was only considered. Nutrients values of
sludge/biomass were ignored and therefore, associated N20 emission
from the applied land was also ignored.
