By analyzing the published literatures of wheat and maize fields in North China, the effects of different farming methods on N 2 O emissions and crop yields in grain fields were determined. The results showed that in the North China grain field, the no-tillage technology reduced the N 2 O potential in the wheat season, while the N 2 O difference in the corn season using no tillage, conventional tillage, deep pine and alfalfa was not significant. Therefore, the implementation of no-till measures in the north wheat grain field in North China can reduce emissions and increase production, while the corn field suggests conventional tillage, deep pine or alfalfa cultivation on the basis of straw returning, which can stabilize production and reduce emissions.
