      abstract     = {The winter wheat–summer maize rotation system in the
                      North China Plain is a major source of nitrous oxide (N2O)
                      emissions due to high nitrogen (N) fertilizer and irrigation
                      water inputs. However, a detailed understanding of the
                      contribution of N2O production sources is still limited
                      because of the complexity of N2O generation in soils and a
                      lack of relevant field studies. Moreover, the efficiency and
                      mechanisms of N2O mitigation approaches in this area, i.e.
                      the use of nitrification inhibitors, remains poorly
                      understood. To elucidate the N2O production pathways from
                      this rotation system and to evaluate the effect of a widely
                      used nitrification inhibitor 3,4-dimethylpyrazole phosphate
                      (DMPP) on mitigating N2O emissions, we monitored N2O fluxes
                      and analyzed isotopomer ratios of soil-emitted N2O during
                      one rotation year. Results indicate that the application of
                      DMPP significantly reduced N2O emissions by $67\%$ in the
                      winter wheat season and $47\%$ in the summer maize season.
                      Isotopomer analysis revealed that in the N-fertilized
                      treatment, nitrification and/or fungal denitrification
                      accounted for up to $36\%$ of the N2O emission peaks
                      observed after fertilization and irrigation events, whereas
                      the nitrifier denitrification pathway was likely to be the
                      major source, accounting for the remaining N2O emissions.
                      The high effectiveness of the nitrification inhibitor on
                      mitigating N2O emissions at high soil moisture may be
                      attributed to the dual inhibitory effect on nitrifier
                      denitrification, i.e. reducing the supply of nitrite, which
                      is the substrate of nitrifier denitrification and inhibiting
                      ammonia-oxidizing bacteria activities, which carry nitrifier
                      denitrification.},
