Contribution of conservation tillage (CT) to reducing the carbon footprint of crop production The CFI of conservation tillage (CT) showed a trend of decreasing by approximately 23.40%.
It did not reach statistical significance compared with non-conservation tillage (NCT) (Fig. 5 A).
Temperature and precipitation have a certain regulating effect on CFI, both of which show an increasing trend first and then decreasing with the increase of factor value.
Three-way interactions among soil pH/temperature, OMR, and CT were not significant, whereas precipitation showed a marginally significant three-way interaction with OMR and CT, suggesting that the effect of OMR on CFI depended on both precipitation amount and CT regime.
