      abstract     = {The application of nitrification or urease inhibitors
                      together with nitrogen (N) fertilizer has been proposed to
                      reduce N losses, including nitrous oxide (N2O) emissions,
                      from agricultural soils. We measured N2O fluxes, crop yield
                      and plant N content over 3 years (2012–2015) to evaluate
                      the long-term effects of nitrification and/or urease
                      inhibitors on N2O emissions, crop production and N use
                      efficiency (NUE) in an intensively farmed wheat–maize
                      system in northern China. The experiment consisted of the
                      following five treatments: 1) CK, no N fertilizer; 2) U,
                      urea; 3) NI, urea with 3,4-dimethylpyrazole phosphate
                      (DMPP); 4) UI, urea with N-(n-butyl) thiophosphoric triamide
                      (NBPT); and 5) NIUI, urea with combined DMPP and NBPT.
                      Compared with the U treatment, the NI, NIUI and UI
                      treatments mitigated cumulative N2O emissions by $55\%,$
                      $40\%$ and $21\%$ in the maize season, respectively, and
                      $47\%,$ $40\%$ and $33\%$ in the wheat season, respectively.
                      The annual direct emission factors of N2O for the U, NI, UI
                      and NIUI treatments were $0.4\%,$ $0.1\%,$ $0.3\%$ and
                      $0.2\%,$ respectively. The NIUI, NI and UI treatments
                      increased the annual crop yield $(7\%,$ $6\%$ and $4\%)$ and
                      the NUE $(15\%,$ $10\%$ and $7\%)$ relative to the U
                      treatment. The NI treatment showed the best effect on
                      mitigating N2O emissions, but its efficacy was reduced when
                      applied together with UI. This indicates that more studies
                      are required focusing on the performances and mechanisms of
                      these two inhibitors in alkaline and low organic carbon
                      soils.},
