Abstract

The study of the taxonomic diversity of the prokaryotic microbiome in the carbonate chernozem of the Republic of Moldova at the phylum level is taking place for the first time. It was found that the spectrum of prokaryotic commu- nities consists of 17 components, which denotes an apparently high biological variety of prokaryotes. The assess- ment of prokaryotic diversity using the Shannon, Margalef and Jacquard ecological indices revealed, however, that prokaryotic communities are not only characterized by low biological diversity. Depending on the type and amount of fertilizer, their biological diversity is constantly decreasing, also recording a high similarity between options. This situation may condition the decline of soil health and, most importantly, human health. Given the complex relations- hip between soil microorganisms and the human microbiome, the preservation and/or increase of the diversity of soil microorganisms becomes an extremely important task for humanity in order to support and maintain life on Earth.
