Means (and SE) of SOC, N and P in organic layer and mineral soil of the beech, mixed (beech-oak) and oak stands in the three transects A–C (n = number of plots). In the case of SOC and N, total pools are given for organic layer and mineral soil. P is resin-extractable P in the mineral soil and total P in the organic layer. Profile totals (MS total) of SOC, N and P were calculated for a depth of − 100 cm by extrapolation. No samples were taken in the linden forests
