Spatial variability of forest floor and topsoil thicknesses and their relation to topography and forest stand characteristics in managed forests of Norway spruce and European beech

Original language description

Soils play a significant role in climate regulation, especially due to soil organic carbon (SOC). The SOC pool is therefore modeled for various environments, and forest floor and topsoil thicknesses are important parameters for most of these models as they store most of the SOC. However, the forest floor and topsoil thicknesses show high spatial variability which is a result of multiple factors which are not agreed upon among scientists. Out of these factors, we choose topography parameters (elevation, slope, and topography wetness index) and forest stand characteristics (stand age, dominant tree species, and forest floor cover), and soil moisture, and we analyzed their relationship to the forest floor and topsoil thicknesses. The study was performed in a managed submontaneous forest in Central Europe dominated byPicea abies(L.)Karstenwith small patches ofFagus sylvaticaL. or other species. The thicknesses of the O horizons (Oi, Oe, Oa) and topsoil were measured at 221 sampling pits. Geographically weighted regression showed that the spatial variability of the overall forest floor plus topsoil thickness (OA) is responsible for 8% of its variability. The thickness of the OA is the most strongly controlled by forest floor cover explaining approximately 6% of its variability and soil moisture explaining 2-6% of the variability. The Oi + Oe horizon thickness is controlled only by forest floor cover explaining 10.7% of its variability, and the thickness of Oa + A horizon can be explained mainly by soil moisture in mineral horizon explaining 9% of the variability.
