Physicochemical soil properties correlated to conditional residual variance within intercept-only linear mixed models of SOC content, the rates of fast pool C decay (k1) and slow pool C decay (k2). Residuals from LMM (1) for SOC, k1, and k2 were parsed by climate, above and below the median of each climate variable, and assessed for spearman correlation to measured soil physicochemical properties. Correlations within a response variable that are greater than the Bonferroni adjusted α of all comparisons (0.05/308 = 0.000162) are labeled as non-significant (NS).
