By the evaluation of elaborated soil estimation maps (M. 1 : 5000), the distribution of the deep humic soils could be identified with the loess distribution. A connection to the existing chernozem areas was possible. Grounded on climate theories, nontree pollen analyses, interstadial chernozem formation and the history of vegetation of this area...
