title: Comparative Characteristics of the Lithochemical Features of Chernozems in The Northern Azov Sea Region and Crimea
abstract: The article discusses modern approaches to the study of weathering and soil formation processes in soils. It offers comparative characteristics of migration-segregation (ordinary carbonate) chernozems and textural-calcareous (southern) chernozems formed under conditions of the steppe regions in the Crimea and Rostov region. Lithochemical indices were used to determine the relative age of soils and establish the relationship between soil formation and weathering. CIA index characterizes the degre
