ON BASIC ELEMENTARY SOIL-FORMING PROCESSES IN URBAN SOILS OF ROSTOV

Abstract

The paper presents the results of studying the profile distribution of macroelements in Calcic Chernozems park-recreational zones of Rostov agglomeration in the context of conjugated elementary soil-forming processes. Macroelement composition indicates that along with the previously described intensification of two leading elementary soil-forming processes, such as humus formation / humus accumulation and carbonate migration, during the change from herbaceous to woody plant formations there is also intensification of the associated elementary soil-forming process – oglinisation. This is identified by changes in the bulk chemical composition and redistribution of its main components in soil profiles under forest plantations.
