Abstract
The objective of this study was to determine the soil organic carbon stock (T-SOC stock) in different mountain soils in the Babia Góra National Park (BNP). Environmental factors, such as the topography, parent material, and vegetation, were examined for their effect on carbon stock. Fifty-nine study plots in different BNP locations with diverse vegetation were selected for the study. In each study plot, organic carbon stock was calculated, and its relationships with different site factors were determined. The results reveal that the SOC stocks in the mountain soils of the BNP are characterized by high variability (from 50.10 to 905.20 t ha − 1 ). The general linear model (GLM) analysis indicates that the soil type is an important factor of soil organic carbon stock. Topographical factors influence soil conditions and vegetation, which results in a diversity in carbon accumulation in different mountain soils in the BNP. The highest carbon stock was recorded in histosols (>550 t C ha − 1 ), which are located in the lower part of the BNP in the valleys and flat mountain areas.

The studied soils were characterized by a high variation in the base cation content (Table 1), and the results obtained for the bulk density show diversity in all the profiles (0.1–1.4 g cm−3 )
Summary
Forest ecosystems contain the highest organic carbon stock among terrestrial ecosystems [1,2]. Forest systems cover more than 4.1 × 109 hectares of the Earth’s land area [3]. In these ecosystems, organic carbon accumulates in the biomass of trees, shrubs, and herbaceous plants, as well as in the soil horizons that form the soil profile. It is estimated that the carbon contained in soil constitutes 75%. Soil carbon (C) stock is influenced by several environmental factors, such as the topography, slope, exposure, elevation, climate, parent material, and vegetation [5,6,7,8]. Vegetation affects soil parameters because it supplies organic matter that varies in quantity and quality [9]
