Soil concentrations of organic carbon, total nitrogen, C:N ratio, and N:Presin ratio. Mean concentration (and standard error) of (a) organic C, (b) total N, (c) C:N ratio and (d) N:Presin ratio in mineral soil profiles under beech (solid line) and pine stands (dotted line). Different capital letters mark significant differences between stand types for the whole profile (ANOVA). Given are means and standard error of each nine stands, in which each 10 profiles were investigated. Depth-wise differences were not significant
