Ecological and Genetic Features of Soils of Mountain Valleys of Dagestan and Their Use for Perennial Plants

摘要

The ecological and genetic features of the formation and dispersion of soils of mountain river valleys of liigh-altitude zones and their difference from similar deltaic plains of Caspian lowlands are considered. Based on complex studies of agricultural soils, the altitude limits for perennial crops depending on the position of sun-exposure of the adjoining slopes and hydrothermal conditions of mountain river valleys are determined.
