Statistical parameters of agro-gray soil varieties obtained on the basis of generalization of information are the zero-monitoring cycle in the studied region and serve as reliable criteria for the diagnosis of these soils. Numerical indicators reflect the results of past and current soil processes. In agricultural production, the role of the arable layer with all the properties that determine the level of grain yield is especially important. Thus, in the studied varieties, there is a stable relationship between the amount of silt fraction, food elements, and humus. Thus, the clay variety is characterized by the highest fertility of the arable layer - an average content of mobile potassium (10.5 mg/100 g), an increased content of phosphorus (12.4 mg/100 g), low-concentration of humus (2.9%), close to neutral reaction of the medium (5.8 pH). Comparative analysis of soil formation products in the analyzed soil varieties shows their regular change in morphometric characteristics and properties of soils, reflects the result of soil formation processes, partly-economic activity.
