Effects of N additon on (a) modeled decomposition rate (M) and (b) the ratio of BG (β-D-glucosidase) to POX (polyphenol oxidase). BG and POX are two C-acqusition enzymes, decomposing labile and non-labile organic C, respectively. CT: control; LN: low-N addition; HN: high-N addition. Error bars denote the standard error (n = 3). Different letters indicate significant difference (P < 0.05) between treatments
