The effect of fertilizer practices on N balance and global warming potential of maize–soybean–wheat rotations in Northeastern China.

Highlights: [•] Integrated NPK plus manure fertilization increases SOC and soil total N. [•] The application of phosphorus (P) with NK maintains SOC in maize–soybean–wheat rainfed cropping systems. [•] The application of NPK plus manure fertilizer can achieve high grain yield and low GWP. [ABSTRACT FROM AUTHOR]
