Soil reproduction in steppe ecosystems of different ages

Abstract

Features of the development of steppe chernozems were established based on the study of soils of different age groups at archaeological sites. Differences in the formation of phytomass and morphological maturity of the soil profile in the recovery of different age successions were shown. A regional model of the humus horizon steppe soil over time allowed us to estimate the time interval at which the processes of humus accumulation and morphological maturity of the soil profile are relatively at equilibrium
