BG refers to ß-glucosidase, BX refers to ß–xylosidase, CB refers to cellobiohydrolase, and NAG
refers to N-acetyl glucosaminidase.
Silt + clay, soil organic carbon, and total nitrogen data were taken from Ontl et al. (2013)
NO3-, NH4+, and pH were not significantly correlated with any other variable.
