  1. For, example, 2 MRM tests were significant of the 18 ran to relate16S community profiles from 3 depths to 6 fast SOC estimated parameters. Random Forest analyses were considered significant if the community profile could explain ≥30% of the variance of a given estimated SOC parameter. MRM tests were significant when P < 0.05. Correlations for individual SOC parameters are presented in detail in Table 3
