Partial regression plots of C response predicted by physicochemical soil properties across 20 field locations sampled by horizon to 1 m. Models with the highest marginal R2 after model selection by AICc are visualized for each C response variable: SOC content (A), the slow pool decay rate, k2 (B), and the fast pool decay rate, k1 (C). All data were mean-centered and scaled by relative standard deviation for comparison. Regression coefficients are shown as fitted lines with 95% confidence intervals.
