What is it about?
The contradiction between the high grain yield of summer maize and greenhouse gas (GHG) emissions in the field can be resolved by selecting effective nitrogen sources and fertilization methods. In this study, it was demonstrated that the application of urea-ammonium nitrate solution under fertigation resulted in higher summer maize yield and nitrogen use efficiency and reduced GHG emissions compared with urea.

Why is it important?
This study integrated UAN application rates and application methods, and conducted a systematic study on summer maize yield, NUE, GHG emissions and the dynamic changes of soil NO3−-N and NH4+-N content.
