Abstract
The geography, physical and physicochemical properties of the Podilski Tovtry rendzinas have been studied. The paper describes the differences in the rendzina ontogenesis caused by lithological, geomorphological, climatic conditions and human activities. The role of the lithological factor in the formation of spatial heterogeneity and the change in the Podilski Tovtry rendzina components have been justified. Differences in physical and physicochemical properties of the studied soil in the natural and man-disturbed state have been established.

The geography, physical and physicochemical properties of the Podilski Tovtry rendzinas have been studied
The Podilski Tovtry rendzinas are intrazonal, biolithogenic soils formed on eluvial-deluvial sediments of the Neogene limestone and carbonate loess loams. This spatial heterogeneity of the soil forming rocks has caused the formation of the different morphological structure and properties of rendzinas and pararendzinas, which complicates their classification as before neither brown rendzinas nor brown pararendzinas were classified in the Ukrainian soil science
We have used the works of Polish soil scientists [1,2,3, 7,8,9, 13], which have described approaches to the study of the structure and properties of different rendzina subtypes and held their correlation with the world reference base (WRB)
Summary
The geography, physical and physicochemical properties of the Podilski Tovtry rendzinas have been studied. The Podilski Tovtry rendzinas are intrazonal, biolithogenic soils formed on eluvial-deluvial sediments of the Neogene limestone and carbonate loess loams. This spatial heterogeneity of the soil forming rocks has caused the formation of the different morphological structure and properties of rendzinas and pararendzinas, which complicates their classification as before neither brown rendzinas nor brown pararendzinas were classified in the Ukrainian soil science. In addition to the spatial changes in the rendzina subtypes caused by lithogenic divergence of the soil forming rocks, unsustainable agricultural development, which leads to the intensification of degradation processes and the formation of agrorendzinas with their specific properties, has a significant impact on their properties and structure. The Podilski Tovtry – the middle Miocene reef formations were formed 13-18 million years ago in the territory of the Podilska Upland in warm coastal waters of the Central
