Figure S6 : Proportion of extracellular enzyme activity (kg-1 soil organic carbon [C]) below 20 cm in the top meter for α-glucosidase (AG), β-glucosidase (BG), cellobiohydrolase (CB), β-xylosidase (BX), N-acetylglucosamine (NAG), leucine aminopeptidase (LAP), and acid phosphatase (AP) across (A) and among (B) soil orders. Error bars show standard error of the mean (Figure panel A: n = 19; Figure panel B: Inceptisol: n = 4, Mollisol: n = 5, Ultisol: n = 3).
