Cross-site comparison of soil organic carbon (SOC)-curvature and –thickness relations. Cross-site evaluation of four catchments and the larger Reynolds Creek Experimental Watershed (RCEW) comparing the mesic north- and xeric south-facing aspects of Johnston Draw best-fit lines (solid black lines) and 95% confidence intervals (gray shaded areas) for the relationships between SOC stocks and (a) curvature and (b) soil thickness.
