Soil pools of C and N of different forest history stages. Mean pools of organic C in the soil under ancient beech (BeAnc), ancient pine (PiAnc) and recent pine stands (PiRec) for the total profile to 100 cm (including organic layer, data for 60–100 cm were computed by extrapolation) (a), the mineral soil (0–100 cm) (b), and the organic layer (c), and mean pools of total N in the three forest categories for the total profile to 100 cm (including organic layer) (d), the mineral soil (0–100 cm) (e), and the organic layer (f). Given is the population mean (black dot) and the standard error, and the individual means of the stands (open circles). Significantly different population means between the stand types are marked with different small letters. The stands comprise those analyzed in this study and seven additional recent pine stands from western Brandenburg according to Leuschner et al. (2013)
