Table 9 Pools of SOC, N, P and basic cations in soil profiles under beech, mixed and oak forests (means and SD of n plots in the three transects). In the case of SOC and N, total pools are given for organic layer (OLC and OLN) and mineral soil (SOC and STN). For P, total pools in the organic layer and resin-exchangeable pools (Pav) in the mineral soil are given. For the basic cations (Ca, Mg, K), total pools of the organic layer and BaCl2-exchangeable pools of the mineral soil are given. Pools of SOC, STN an Pav were calculated to a depth − 100 cm, the pools for Ca+2ex, Mg+2ex and K+ex to a depth of − 40 cm. Base saturation (BS) and C/N ratios for the mineral soil were averaged over the three depths 0–10 cm, 10–20 cm and 20–40 cm. No soil samples were taken in the linden forests. Significant differences (p ≤ 0.05) between forest types are indicated by different small letters (Kruskal–Wallis test with post hoc Pairwise Wilcoxon Rank Sum Test). Variables with significant differences are in bold

From: Climate warming-induced replacement of mesic beech by thermophilic oak forests will reduce the carbon storage potential in aboveground biomass and soil
