Short summary
Through a 2-year field experiment and meta-analysis, we found higher GHG (dominated by CH4 emission) and Nr (dominated by NH3 volatilization) was released from rice production in TLR, causing great environmental costs, due to direct straw incorporation and excessive N fertilization. Sensible N reduction reduced the GHG and Nr to some extent, but further mitigation is possible, especially for CH4 emission and NH3 volatilization, considering current incorporation pattern of straw and N fertilizer.
