[Display omitted] •SOC changes were simulated in three sites with contrasting soils and climates.•Conventional tillage (Conv − R and Conv + R) led to SOC decline in all sites.•No-tillage (NT) could slightly increase the annual SOC in all sites.•C sequestration rate of 0.4% yr−1 is achievable under c...
