1pH was not measured on PINE and MDRN soils because of limited soil collected.
Table 2 : Marginal R2 values for mixed-effects models with soil clay concentration, pH, or fungi:bacteria as the sole fixed effect, and soil pit as a random effect on EE activity normalized by microbial biomass (MB) or soil organic carbon (SOC) concentration in top- (< 20 cm) and sub-soils (> 20 cm). Key: α-glucosidase (AG), β-glucosidase (BG), cellobiohydrolase (CB), β-xylosidase (BX), N-acetylglucosamine (NAG), leucine aminopeptidase (LAP), and acid phosphatase (AP) activity. Bolded values represent a significant (α = 0.05) effect and +/- signifies the direction of the effect (surface soil: n = 29, subsoil: n = 114).
