Approximately 47% of anthropogenic
N2O emissions are released from agricultural soils through
nitrification and denitrification (IPCC, 2013), which are mainly
affected by management practices, such as irrigation and
fertilization (Burton et al., 2008). In fertilized soils, increasing
rates of fertilizer application are the primary cause of enhanced
N2O emissions because nitrate is used as an alternate terminal
electron acceptor under aeration conditions to produce N2O
(Burton et al., 2008; Venterea et al., 2012).
