Topsoil contents of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn) and related soil properties such as pH and carbon (C) and nitrogen (N) contents were studied in the two main forest types of the Archbishopric forests in the area of the Jeseníky Mts., Czech Republic. Statistical comparisons were carried out between mature Norway spruce (NS) and European beech (EB) stands, separately for the forest floor (horizons FH) and the mineral (0–2 cm depth) soil. The FH horizons under EB showed higher contents of Zn, as compared to NS. In comparison, potentially higher contents of Cd were found under NS. The mineral topsoil under EB showed higher contents of Pb and Zn as compared to NS. In contrast, the pH was higher and the C:N ratio lower under EB, as compared to NS in both soil layers; the latter due to higher C under NS in organic horizons, while higher N under EB in the mineral soil. The results indicate that the species composition of managed forests may have conflicting impacts on soil quality and the accumulation and persistence of heavy metals in forest soils.
