Mountainous meadow chernozem-like soils of high mountains in the North Caucasus region

摘要

Original and literature data on the soil-forming conditions and the morphology, physicochemical properties, and bulk chemical and mineralogical composition of mountainous meadow chernozem-like soils of the North Caucasus region indicate that these soils are developed from the coarse-textured pebbly colluvium of calcareous bedrock under the impact of humus accumulation and clay formation. The intensity of these processes is directly related to the activity of soil biota. Suggestions aimed at improving the classification of high-mountain soils are discussed.
