Soil pool of base cations in the organic layer and in the mineral soil. Total pool of base cations (Ca, K, Mg) in the organic layer of beech (black bar) and pine stands (white bar) (a), and pools of exchangeable base cations in mineral soil profiles to 100 cm depth (data for 60–100 cm were computed by extrapolation) under beech (black bars) and pine stands (white bars) (b). Significantly different pool sizes between the stand types are marked with an asterisk (ANOVA). Given are means and standard error of each nine stands, in which each 10 profiles were investigated
