Highlights: [•] No increase in soil respiration and variable changes in crop yield with biochar amendment in a rice and wheat rotation year. [•] N2O emission greatly decreased consistently with biochar treatments and crop seasons, CH4 emission from rice season increased only at 20tha−1 amendment. [•] An overall net reduction in GHGI of the whole rotation cycle by 10–20% was consistent across the biochar treatments. [Copyright &y& Elsevier]
