“…An important factor forming the sequestration of carbon in calcareous soils is the type of parent rock, which determines the content of calcium and magnesium and the amount and type of clay minerals. All the processes described above lead to the creation of specific morphological properties of Rendzinas with a deep black surface horizon, as well as certain conditions -and specific feature of organic compounds (Wasak et al, 2018). The type of humus is fulvic-humic to humic, the ratio Ch/Cf is from 0.6 to 3.75 (Figure 4).…”

Article InfoThe paper deals with of the relations between the forest ecosystem, calcareous rocks and content and composition of soil organic matter in the Golo Bardo area in West Bulgaria. In that area Rendzinas are used mainly for forestry, viticulture and pastures. A specific study based on the accumulation of soil organic matter according to the data on the composition of the soil organic acids. The research on the soil organic matter composition provided information on the course of the humification processes in studied soils. Soil organic matter accumulation in Rendzinas depends on different factors, such as land use and climatic conditions. Soil has rapid transformations of organic residues and strongly decomposed plant tissue predominates. There are often signs of active work of the soil mesofauna. Studied soils have good reserves of organic carbon high degree of humification. The organic carbon content varies in a wide range from 0.8 to 7.2 %. The humic acids prevail over fulvic acids, and the degree of humification is higher in deeper horizons. According to the C/N ratio the humus type is Mull in almost all horizons. Studied soils are biologically active that have favorable impact over the soil structure and vegetation. Rendzinas have high potential of organic carbon sequestration.

Following the other pedological societies, the Soil Science Society of Poland has launched a programme „Soil of the Year”, and Rędzina (Rendzina) was selected as the soil inaugurating the programme in 2018. Polish term „rędzina” was internationally popularized by Stanisław Miklaszewski in the second/third decade of 20th century and is present in the most soil classification systems as „Rendzina”, „Rendoll”, or „Rendzic” until now. In the Polish tradition, the rendzinas are soils developed from massive rocks rich in calcite, dolomite or gypsum, quite often with admixtures of glacial/periglacial materials, at all development stages. Contemporary classifications of soils in Poland distinguish four main groups (as the types or sub-types): raw rendzina – Calcaric Lithic / Hyperskeletic Leptosols (a minimal thickness of regolith and an initial development of genetic horizons), proper rendzina – Calcaric Leptosols (medium thick profile, but diagnostic horizons are absent), brown rendzina – Calcaric Skeletic Cambisols (have a diagnostic cambic horizon), and chernozemic/humic rendzina – Rendzic Skeletic Phaeozems (have a diagnostic mollic horizon). Rendzina soils are featured by high content of calcium/magnesium, neutral and alkaline reaction, and high base saturation throughout the soil profile, but the individual soil subtypes differ significantly in their usability for agriculture and forestry, depending on the thickness of the soil profile (i.e. a depth to the hard rock or extremely skeletal subsoil), stoniness, texture, and humus content.

The aim of the study was to test the suitability of the 6th edition of Polish Soil Classification (SGP6) in reflecting the typical features of subalpine Bieszczady Mts. soils in comparison with the 5th edition of Polish Soil Classification (SGP5) and the newest version of World Reference Base for Soil Resources (WRB). Five soil profiles located in differentiated in terms of the parent material, topography and vegetation conditions of the natural environment were investigated. On the basis of described morphology and determined properties soils were classified according to different soil classifications. All soils under study were featured by presence of thick A horizons and high content of soil organic carbon accumulated even very deep in the profiles. Some of the mineral topsoil layers were classified as umbric/umbrik horizons. Moreover cambic/kambik horizons were present and in some cases also weak redoximorphic features occurred. The SGP6 enabled to distinguish soils with a thick, organic carbon-rich A horizons as umbrisols, a newly created subtype of grey soils. Furthermore, the soil taxonomic position according to SGP6 was more detailed in relation to the soil trophic status (in case of brown soils) and occurrence of weak redoximorphic features. That was reflected in number of subtypes to which analyzed soils were classified – 4 in SGP6 vs 2 in SGP5.
