Abstrakt: Characterizes lignin decomposition in particle-size fractions from grassland topsoils as influenced by climate. Proportional relationship between lignin-derived phenol concentration and particle size; Reduced lignin decomposition with increasing mean annual temperature; Requisite of additional sources of carbon such as saccharides of root litter.
