AB  - The influence of inorganic fertilizer and compost on background nitrous oxide 
      (N2O) and fertilizer-induced N2O emissions were examined over a maize-wheat 
      rotation year from June 2008 to May 2009 in a fluvo-aquic soil in Henan Province 
      of China where a field experiment had been established in 1989 to evaluate the 
      long-term effects of manure and fertilizer on soil organic status. The study 
      involved five treatments: compost (OM), fertilizer NPK 
      (nitrogen-phosphorus-potassium, NPK), half compost N plus half fertilizer N 
      (HOM), fertilizer NK (NK), and control without any fertilizer (CK). The natural 
      logarithms of the background N2O fluxes were significantly (P<0.05) correlated 
      with soil temperature, but not with soil moisture, during the maize or wheat 
      growing season. The 18-year application of compost alone and inorganic fertilizer 
      not only significantly (P<0.05) increased soil organic carbon (SOC) by 152% and 
      10-43% (respectively), but also increased background N2O emissions by 106% and 
      48-76% (respectively) compared with the control. Total N in soils was a better 
      indicator for predicting annual background N2O emission than SOC. The estimated 
      emission factor (EF) of mineralized N, calculated by dividing annual N2O emission 
      by mineralized N was 0.13-0.19%, significantly (P<0.05) lower than the EF of 
      added N (0.30-0.39%). The annual N2O emission in the NPK, HOM and OM soils 
      amended with 300 kg ha(-1) organic or inorganic N was 1427, 1325 and 1178 g N 
      ha(-1), respectively. There was a significant (P<0.05) difference between the NPK 
      and OM. The results of this study indicate that soil indigenous N was less 
      efficiently converted into N2O compared with exogenous N. Increasing SOC by 
      compost application, then partially increasing N supply to crops instead of 
      adding inorganic N fertilizer, may be an effective measure to mitigate N2O 
      emissions from arable soils in the North China plain.
