About mistakes of the past large–scale soil survey and their exclusion in the future

Abstract

The article is devoted to the analysis of the causes through which in the past large-scale soil survey there were made some mistakes that reduced the value of the performed work. The main ones are the following. Before mapping it was carried boundary between Forest Steppe and Steppe on the southern edge of natural forests, which at that time still remained. The Instruction on large-scale soil survey did not allow distinguishing in the Steppe zone chernozems typical (1957), although allowed the presence of chernozems podzolized and dark grey podzolized soils. In fact, under conditions of developed relief, within the limits of the transition from the Forest-Steppe to the Steppe zone on the southern slopes are formed of Steppe soils, and to the north slopes - Forest-Steppe ones. In the south of Podillia, there are highlighted a large massifs of grey podzolized soils on the loess. In reality there is no loess and brown soils are formed.
