Table 3. Activities of β-glucosidase and N-acetyl-β-D-glucosaminidase in soils from the Rattlesnake Mountain transplant experiment.
Soil codes are lower site native (LN), lower control (LC), lower-to-upper transplant (LU), upper native (UN), upper control (UC), and upper-to-lower transplant (UL). Significant differences (labeled as “a”, “b”, etc.) between soils within depths (based on Turkey’s HSD) were only detected in the 0–5 cm depths; values followed by the same letter are not significantly different. Units are μmol MUB g-1 soil h-1 for both enzymes.
