BIOLOGICAL ACTIVITY OF MOUNTAIN AND PLAIN CHERNOSEM SOILS IN THE CENTRAL CAUCASUS (WITHIN KABARDINO-BALKARIA)

Authors: Gorobtsova O. N., Minkina T. M., Uligova T. S., Tembotov R. K., Khakunova E. M.

A comparative analysis of biological properties of several subtypes of mountain and plain chernosems in the Central Caucasus (within Kabardino-Balkaria) was conducted. Statistically significant differences between the parameters of biological activity in the upper horizons (0 - 20 cm) of the soils under study were revealed. Mountain chernosems are characterized by the high humus content (by 38% on average), an increased activity of dehydrogenase (by 42%) and urease (by 35%), and all microbial parameters (by 12 - 53%).

Ecologo-biological characteristic of natural steppe biogeocenoses in the Central Caucasus (the Terskiy variant of vertical zonation, Kabardino-Balkaria)

Authors: Uligova T. S., Gorobtsova O. N., Tsepkova N. L., Rapoport I. B., Gedgafova F. V., Tembotov R. K.

An ecologo-biological characteristic of the natural steppe biogeocenosis components in Kabardino-Balkaria (within the Terskiy variant of vertical zonation) is given. The research results of biological features of common chernozem calcareous soils (humus contents, enzymatic activity, and soil respiration intensity), their spatial and profile distribution combined with basic ecological factors are represented.
