During the study of the soil cover of the southern part of the East European plain, data on the background content of zinc in the zonal soils of the region were obtained. It was revealed that the average content of this element in the soils of forest-steppe and steppe zones is in a narrow range of 37-45 mg/kg, regardless of the taxonomic affiliation of the formed soil unites. The anthropogenic impact on the concentration of zinc in the upper humus horizon is rather weak and limited to agricultural land use, which probably caused the leveling of the background content of the element over large areas.
