From: How does tillage intensity affect soil organic carbon? A systematic review
Summary effect estimates (difference in SOC, Mg/ha) for stocks data meta-analyses. Three tillage comparisons are shown: NT, no tillage; IT intermediate intensity tillage, HT high intensity tillage (see text for explanation). Diamonds are centred on the summary effect estimate for each meta-analyses, with the points of the diamonds representing the 95% confidence intervals. Numbers in the right hand column are summary effect estimates [lower 95% CI, upper 95% CI]
