Ecological and biological researches in natural biogeocenoses in the area of common calcareous residually meadow chernosem soils in the Central Caucasus (Kabardino-Balkaria)

The ecological and biological characteristic of components from natural biogeocenoses developed on common calcareous residually meadow chernosem soils of the steppe zone in Kabardino-Balkaria, is given. The list of plant species found in the steppe phytocenoses and their ecological characteristics are presented. The species composition and abundance of mesofauna representatives (earthworms) are studied. The biological activity parameters of chernozem soils: humus content, enzymatic activity, soil respiration intensity, carbon content of chernozem microbial biomass (Cmic) as well as their spatial distribution, are defined.
