From: How does tillage intensity affect soil organic carbon? A systematic review
Forest plot for meta-analysis of concentration data for NT–IT comparison at 0–15 cm depth. NT no tillage, IT intermediate intensity tillage (see text for explanation). The summary effect estimate diamond is centred on the summary effect estimate for the meta-analysis, with the points of the diamond representing the 95% confidence intervals. Numbers in the right hand column are summary effect estimates [lower 95% CI, upper 95% CI]
