Abstract
This paper studied the characteristics of the soil which is noticeable degradation process. Open four soil profiles and identified two systematic units of the soil: chernozem and meadow black soil. Studied soils are heterogeneous texture, and are represented by different textural classes: sandy loam, sandy clay loam, silty clay loam, clay, powdered clay, clay loam to clay. The reaction of these lands is moderately alkaline to strongly alkaline. Particularly significant is the total salt content of which is the limiting factor for the production possibilities of the surveyed area. The salt content had a mean value of 0.8% and 0.6% for the soil profile No. 1 and No. 3 (meadow black soil and chernozem) while the increased content of 0.13% noticeable in the surface horizon - A horizon of soil profile No. 2 (chernozem) and in the deeper horizon - C horizon (0.12%), soil profile No. 4 (meadow soils). Based on the characteristics of the study explored the land for afforestation of these habitat types are recommended more resistant to low content of total salts in the soil, which are also economically important species: English oak (Quercus robur), Turkey oak (Quercus cerris) and Black walnut (Juglans nigra).
