Table 7 Mean soil physical and chemical properties (SD in brackets) in the organic layer and three depths in the mineral soil (0–10 cm, 10–20 cm, 20–40 cm) of the three transects (A, B, C) with the corresponding sample size (n). In the case of SOC and N, concentrations (mass%) are given for organic layer (OLC and OLN) and mineral soil (SOC and STN). For P, total contents in the organic layer and resin-exchangeable contents (Pav) in the mineral soil are given. For the basic cations (Ca, Mg, K), total contents in the organic layer and BaCl2-exchangeable contents in the mineral soil are given. Also given are CEC (cation exchange capacity), BS (base saturation), soil texture (percent sand, silt, clay) and storage capacity of available soil water (pAWC). Soil texture analyses were only conducted for the depth of 20–40 cm
