Step nebo les? Ekologické podmínky vzniku a vývoje černozemí ve Střední Evropě / Steppe or woodland? Ecological Conditions of Formation and Evolution of Chernozems in Central Europe

Chernozem became the crucial soil for the beginnings of soil science through the work of Dokuchaev from 1883. Since then the genesis of chernozems in Central Europe has raised many questions among soil scientists, botanists and paleo-environmentalists. While in Eastern Europe chernozems have been described as zonal soils, that are typical for continental steppe and forest-steppe areas, there are areas in Central Europe which are predisposed by their climatic characteristics to the presence of woodlands. The goal of this dissertation is to enrich the discussion about the genesis of chernozems by restoring the environmental conditions that were prevalent during the formation of chernozem soils in Central Europe. Chernozems are usually developed on loess with a very thick and dark organic surface which passes directly to a calcareous horizon. The organic matter underwent a polymerization in dependence on climate contrasts. However, in Central Europe, the climatic characteristics of the areas of chernozems are a bit different. These chernozems are supposed to have been formed under the climatic conditions that dominated Central Europe during the Late Glacial and the Early Holocene. The climatic nuances may contribute to the explanation of the differences in distribution of chernozems ("drier") and...
