From: Divergent accumulation of microbial necromass and plant lignin components in grassland soils
Lignin concentration and composition in the overlaying vegetation of Mongolian grasslands. Organic carbon (OC)-normalized concentrations of lignin phenols and Klason lignin and the ratio of lignin phenols: Klason lignin (a) and the acid-to-aldehyde (Ad/Al) ratios of vanillyl (V) and syringyl (S) phenols (b). Error bars represent the standard error of the mean (s.e.m.) with the number of replicates (n) indicated in the parenthesis. Letters indicate different levels for the same parameter among vegetation types (p < 0.05)
