“…Site types were usually identical with individual edaphic categories of the PNV system, but we made exceptions in well-founded cases (e.g. it is difficult to separate FTs 2B9, 2W1, 2W3 in karst regions -Šamonil 2005, 2007aŠamonil, Viewegh 2005). These ST types were established specifically for this study and are not a part of the PNV system.…”

Based on a map of potential natural vegetation (PNV), actual vegetation was studied in the Mramor locality (106.4 ha). A total of 188 relevés were examined using stratified random sampling. A comparison was made between trends in vegetation variability throughout the entire locality and variability within the defined PNV units. The stratification of the locality according to PNV units was only partly representative of the main trends in vegetation variability, especially at ecologically distinctive sites. On the other hand, in areas with a relatively limited ecological gradient, the sites were "oversampled". The variability of plant communities within PNV units was high. The results of this case study suggest that the need for delineation of PNV units which are homogeneous in terms of production, site and phytocoenosis is overestimated. This delineation neither corresponds to the characteristics of actual ecosystems nor is necessary for the application of a PNV system. A more suitable unit for the development of such a system would be, for example, forest type series.

“…In research covering more than 1800 soil profiles from the entire territory of Germany, Grüneberg et al (2014) confirmed the higher content of organic matter in soil rich in carbonates both for plains and uplands, and for mountainous areas (Table 1). Even if higher concentration of organic carbon (OC) was recorded in soils neighbouring the rendzinas, the stock of OC in rendzinas was higher due to thicker humus horizons (Drewnik 1998, Šamonil 2007, Wasak 2017. Also the analysis of the morphology of organic and humus horizons and their classification showed that rendzinas contain specific humus forms absent in other soils (Kubiena 1953, Miechówka 2002, Ponge et al 2011, Jabiol et al 2013, Zanella et al 2018a, 2018b.…”

The article refers to the stock and sequestration of organic carbon in soils rich in carbonates, particularly in rendzinas. It presents factors determining sequestration of organic carbon in rendzinas in comparison to other soils, and describes the mechanisms of accumulation of organic matter in these soils. Attention was paid to the atypical morphology of organic and humus horizons occurring in soils rich in carbonates, with specificity related to biological processes.

Little is known on soil organic carbon (SOC) stocks in karst areas worldwide, although many of them have seen long-term application of agroforestry systems with a potential for carbon sequestration. Therefore, our study aimed to assess landscape-level SOC concentration and stock in the Silica Plateau, a part of the Slovak Karst Biosphere Reserve located in the Western Carpathians (Slovakia) with a centuries-long agroforestry record. The most represented local soil units are Chromi-Rendzic Leptosols and Chromic Cambisols with clayey loam texture, C/N ratio 9-12, and pH H 2 O 6.6-6.2 in their organo-mineral surface horizons. Mull surface humus form prevails under mixed forest stands dominated by hornbeam (Carpinus betulus L.), oak (Quercus petraea L.), and beech (Fagus sylvatica L.). A total of 2,700 soil samples were collected from 150 soil pits. Both SOC concentrations and stocks were determined for the 0-60 cm mineral soil layer. Soil stoniness was accounted for by means of electrical resistivity tomography. According to the analysis of covariance, cropland SOC concentration (0.026 g g -1 ) is significantly lower compared to forestland (0.040 g g -1 ) and pastureland (0.041 g g -1 ) (P \ 0.01). During the period of 130 years after forest clearing, cropland SOC stock has been reduced at an exponential decay rate of ca 0.002 year -1 , while the SOC stock in pastureland has increased following land use change from cropland by approximately 30% during the same period of time. Irrespective of land use history, overall SOC stock is high reaching on average 207.4 Mg ha -1 , out of which 66% are stored within 0-30 cm and 34% within 30-60 cm soil layers.
