Abstract:
The scientific paper presents the experimental data obtained in the course of the environmental and reclamation
monitoring of the hydro-geological and reclamation condition of irrigated soils in the southern steppe of Ukraine, their
chemical composition is determined. On the basis of the analysis of water and salt regime of the soils in the areas under
study for reclamation and water supply construction, on the basis of many years’ research, the study suggests the
method for determining agrolandscape typicality considering the properties of soil chemical composition. The basis of
this method is the following principle: the confidence intervals of neighboring regression lines coincide (overlap) on a
certain interval of values, so they are typical on this interval of values. The study establishes that according to this
method the landscapes of Kherson Prysyvashshia and Askania steppes are typical by the specificity of the formation of
soil chemical composition by 83.5% that makes it possible to compare the research results obtained on both landscapes
and proves the typicality of the field experiment
