Abstract
The article presents the results of the study of fallow lands in ancient agricultural areas of the North-Western Crimea which were subject to repeated phases of agricultural activity at different time periods: the Late Bronze Age, antiquity and the last 150-200 years. The differences in biogeochemical flows for virgin soils and fallow lands were analyzed using the chemical elements that determined the composition of secondary clay minerals. The most informative and evolutionarily significant biogeochemical indicators of relict agricultural loads and duration of fallow regime were specified.
