“…Eckmeier et al 2007) are unreliable due to the rapid disintegration of carbonate shells of molluscs in decalcified humus horizons. Therefore, many key questions related to the genesis and age of chernozemic soils remain unanswered, and existing reconstructions of the soil cover evolution are largely based on indirect evidence from fossil and other soils that were preserved in archaeological sites (Alexandrovskiy et al 2014, Eckmeier et al 2007, Ehwald et al 1999, Kaba³la et al 2019b.…”

Diverse chernozemic soils featured by thick mollic horizon, rich in humus, dark-coloured, structural, and saturated with base cations are relatively common in the loess-belt of SW Poland. It is postulated, that most of these soils may have similar initial (chernozemic) history of thick humus horizon, related to climate conditions and vegetation in the Late Pleistocene and the Neolithic periods. However, these soils exist on various bedrocks and under different moisture conditions that led to the development accompanying features and variable classification of soils, both in Polish and international soil classifications. The aim of the paper is to presents the most important variants of loess-derived chernozemic soils of SW Poland, in relation to local conditions, which influenced soil transformation and present spatial diversification. ‘Typical’ chernozems (WRB: Calcic Chernozems), which have a mollic horizon and secondary carbonates, but are free of strong redoximorphic features, are rather uncommon in the region. Whereas, the black earths (WRB: Gleyic/Stagnic Chernozems/Phaeozems), featured by the presence of mollic horizon and strong gleyic or stagnic properties in the middle and bottom parts of the profiles, are predominant loess-derived chernozemic soils in SW Poland. Their most specific forms, developed on the clayey bedrock, are black earths with a vertic horizon (WRB: Vertic Stagnic Phaeozems). The strongly leached chernozemic soils developed over permeable subsoils, lacking carbonates and free of (strongly developed) stagnic/gleyic properties are called grey soils, often featured by the presence of subsurface diagnostic horizons cambic or luvic (WRB: Cambic/Luvic Phaeozems).

“…The major differences of spatial distribution were located in the northern provinces in Mongolia (Dornod and Hentiy) and Kazakhstan (Pavlodar and Qaraghandy). High productivity did not result in higher carbon sequestration in the southwest part of the Russian grasslands due to the high soil respiration rate in the red soil of the North Caucasus (Alexandrovskiy et al 2014).…”

The temperate Eurasian steppe (TES) is a region where various environmental, social, and economic stresses converge. Multiple types of disturbance exist widely across the landscape, and heavily influence carbon cycling in this region. However, a current quantitative assessment of the impact of disturbances on carbon sequestration is largely lacking. In this study, we combined the boreal ecosystem productivity simulator (BEPS), the Shiyomi grazing model, and the global fire model (Glob-FIRM) to investigate the impact of the two major types of disturbance in the TES (i.e. domestic grazing and fire) on regional carbon sequestration. Model performance was validated using satellite data and field observations. Model outputs indicate that disturbance has a significant impact on carbon sequestration at a regional scale. The annual total carbon lost due to disturbances was 7.8 TgC yr −1 , accounting for 14.2% of the total net ecosystem productivity (NEP). Domestic grazing plays the dominant role in terrestrial carbon consumption, accounting for 95% of the total carbon lost from the two disturbances. Carbon losses from both disturbances significantly increased from 1999 to 2008 (R 2 = 0.82, P < 0.001 for grazing, R 2 = 0.51, P < 0.05 for fire). Heavy domestic grazing in relatively barren grasslands substantially reduced carbon sequestration, particularly in the grasslands of Turkmenistan, Uzbekistan, and the far southwest of Inner Mongolia. This spatially-explicit information has potential implications for sustainable management of carbon sequestration in the vast grassland ecosystems.

Various transitional forms between Chernozems/Phaeozems and Luvisols/Retisols have been reported from Central and Eastern Europe (Borowiec 1968;Chendev et al 2017;Khitrov et al 2019), but the most spectacular documentation (including the dating) of the processes of chernozem degradation provide the studies in the archaeological sites, in particular on kurgans (Barczi et al 2006;Alexandrovskiy et al 2014;Vyslouñilová et al 2014b;Kaba³a et al 2019b).…”

“…These inconsistencies have their source (a) in the transitional character of climate and vegetation that influence the soil forming (transforming) processes, and (b) in the subsequent changes of the environmental conditions during the Holocene period which made chernozems polygenetic soils -presently existing under different climate and vegetation than these in the time of their development and further transformation (Vyslouñilová et al 2014a(Vyslouñilová et al , 2014b. Also, the land use and other human impacts may greatly influence the direction and scale of chernozem evolution or degradation, sometimes shifting them to the other classification units (Kalinina et al 2011;Lorz and Saile 2011;Zádorová et al 2013;Alexandrovskiy et al 2014;Novák et al 2014;Chendev et al 2017;Smetanová et al 2017;ðíñala et al 2019).…”

Chernozemic soils are distinguished based on the presence of thick, black or very dark, rich in humus, well-structural and base-saturated topsoil horizon, and the accumulation of secondary carbonates within soil profile. In Central Europe these soils occur in variable forms, respectively to climate gradients, position in the landscape, moisture regime, land use, and erosion/accumulation intensity. “Typical” chernozems, correlated with Calcic or Haplic Chernozems, are similarly positioned at basic classification level in the national soil classifications in Poland, Slovakia and Hungary, and in WRB. Chernozemic soils at various stages of their transformation are placed in Chernozems, Phaeozems or Kastanozems, supplied with respective qualifiers, e.g. Cambic, Luvic, Salic/Protosalic, Sodic/Protosodic etc. Some primeval Chernozems thinned by erosion may still fulfil criteria of Chernozems, but commonly are shifted to Calcisols. Soils upbuilt (aggraded) with colluvial additions may also retain their original placement in Chernozems, getting supplementary qualifier Colluvic. “Hydromorphic” chernozemic soils, in many CE systems are placed as separate soil type (“czarne ziemie” or “čiernice”) at the same level with “typical” chernozems. Classification of these soils in WRB depends on the presence of chernic horizon, depth of secondary carbonate accumulation and depth of gleyic/stagnic properties, and may vary from Gleyic/Stagnic Chernozems/Phaeozems to Mollic Gleysols/Stagnosols. Although WRB classification differs from national classifications in the concepts and priorities of classification, it provides large opportunity to reflect the spatial variability and various stages of transformation/degradation of chernozemic soils in Central Europe.
