      abstract     = {Fertilizer nitrogen (N) application has been shown to
                      impact both methane (CH4) and nitrous oxide (N2O) emissions
                      from rice-based crop systems, yet the responses of CH4 and
                      N2O fluxes to N fertilizer applications in subtropical
                      rice–rapeseed rotation systems are not well documented. A
                      three-year field experiment was conducted to simultaneously
                      measure the fluxes of CH4 and N2O from a subtropical
                      rice–rapeseed rotation system under three N fertilization
                      treatments (control with no N fertilizer addition [CK],
                      optimized N fertilizer management practice in accordance
                      with the recommended N fertilizer application rate of 150 kg
                      N ha−1 season−1 [OP], local farmers common N fertilizer
                      management practice with 250 kg N ha−1 season−1 [CP]) in
                      southwestern China. Results showed great intra- and
                      inter-annual variations in CH4 and N2O emissions along with
                      the temporal variations of environmental conditions,
                      emphasizing the necessity of multi-year measurements to
                      achieve representative estimates. Nitrogen fertilization
                      tended to increase N2O emissions and to inhibit CH4
                      emissions. The direct N2O emission factors (EFd) for the
                      rice systems (mean: $0.99\%)$ were higher than those for the
                      rapeseed systems (mean: $0.71\%).$ In addition, the
                      rice-growing season dominated annual CH4 emissions
                      $(>97\%),$ which on average represented $87\%$ of the annual
                      total global warming potential (GWP) of CH4 and N2O
                      emissions across experimental treatments and years. Linking
                      total GWP of CH4 and N2O emissions with grain yields, the
                      average annual yield-scaled GWP for the control (1467 kg
                      CO2-eq Mg−1 grain) was significantly higher than for the
                      OP (700 kg CO2-eq Mg−1 grain) and CP (682 kg CO2-eq Mg−1
                      grain) treatments (P < 0.05). Given the comparable area- and
                      yield-scaled GWP between the CP and OP treatments, the OP
                      treatment reduced local farmers’ common N fertilizer
                      application rate by $40\%$ and tended to maintain crop grain
                      yields, however it also reduced N surplus and off-site N
                      losses in the subtropical rice–rapeseed rotation systems
                      of southwestern China.},
