metadata.value: Restoration of anthropogenically disturbed soils is an urgent problem in modern ecology
  and soil biology. Restoration processes in northern environments are especially important, due to the
  small amounts of fertile land and low levels of natural succession. We analyzed the soil microbiota,
  which is one of the indicators of the succession process is the soil. Samples were obtained from three
  disturbed soils (self-overgrown and reclaimed quarries), and two undisturbed soils (primary and
  secondary forests). Primary Forest soil had a well-developed soil profile, and a low pH and TOC
  (total organic carbon) amount. The microbial community of this soil had low richness, formed a
  clear remote cluster in the beta-diversity analysis, and showed an overrepresentation of Geobacter
  (Desulfobacteriota). Soil formation in clay and limestone abandoned quarries was at the initial stage,
  and was caused by both a low rate of mineral profile formation and severe climatic conditions in
  the region. Microbial communities of these soils did not have specific abundant taxa, and included
  a high amount of sparse taxa. Differences in taxa composition were correlated with abiotic factors
  (ammonium concentration), which, in turn, can be explained by the parent rock properties. Limestone
  quarry reclaimed by topsoil coverage resulted in an adaptation of the top soil microbiota to a novel
  parent rock. According to the CCA analysis, the microbial composition of samples was connected
  with pH, TOC and ammonium nitrogen concentration. Changes in pH and TOC were connected with
  ASVs from Chloroflexota, Gemmatimonadota and Patescibacteria. ASVs from Gemmatimonadota
  also were correlated with a high ammonium concentration.
