Meta-analytic effects of land use and management treatments on soil C stocks, shown separately for organic horizons, mineral soils, and whole soil profiles. The plot shows the mean effect size (as the ln-transformed response ratio R), bootstrapped confidence interval, and sample size for each treatment and depth with sufficient data. Bold sample sizes indicate meta-analytic groups with confidence intervals not overlapping 0% change (indicated with a dotted vertical line)
