Comparison of relative stable carbon values from texture and soil organic carbon (SOC) samples within an independent dataset, using either the traditional equation (1) or the new equation (2) to calculate absolute stable carbon. The red line indicates when relative stable carbon is overestimated (>100%). Data are plotted against the sample's total SOC content (A) or silt + clay content (B).
