Impact of soil amendments on nitrous oxide emissions and the associated denitrifying communities in a semi-arid environment.

ABSTRACT: Denitrifying bacteria produce and utilize nitrous oxide (N₂O), a potent greenhouse gas. However, there is little information on how organic fertilization treatments affect the denitrifying communities and N₂O emissions in the semi-arid Loess Plateau. Here, we evaluated how the denitrifying communities are responsible for potential denitrification activity (PDA) and N₂O emissions. A field experiment was conducted with five fertilization treatments, including no fertilization (CK), mineral fertilizer (MF), mineral fertilizer plus commercial organic fertilizer (MOF), commercial organic fertilizer (OFP), and maize straw (MSP). Our result showed that soil pH, soil organic carbon (SOC), and dissolved organic nitrogen (DON) were significantly increased under MSP t
