A comprehensive analysis of the microbiome in the complete profile of virgin light-colored solonetz soil at the territory of Dzhanybek experimental station

Under study was the microbiome structure in virgin light-colored hydromorphized solonetz soil by using molecular-genetic and cultural methods. It was shown that the diversity of the microbial community is constantly decreasing down the soil profile being sharply declined in the solonetz horizon. Against the background of decreasing the biodiversity some groups of Proteobacteria are prevailed in the solonetz horizon and in the lower part of the profile. An unusually higher share of Crenarchaeota (almost 20% of the community) is observed in the topsoil.
