This work describes the microbial community structure of continuously revegetated chronosequence a former sand quarry, which demonstrates unique example nearly complete soil restoration in less than 100 years. Samples were collected at five time points (0, 3, 30, 70 years and mature soil) from entire set horizons, revealing history pedogenesis. Real-time PCR was applied to quantitatively describe bacterial archaeal communities. High-throughput sequencing V4 variable region 16S rRNA gene used identify abundant taxa. A beta-diversity analysis revealed that prokaryotic responded strongly processes organic matter accumulation corresponding evolution into discrete horizons. Changes microbiota course profile three groups prokaryotes, tended accumulate specific horizons might be associated with certain soil-forming processes, including plant roots growth. research showed heuristic potential horizon profiling microbiological studies as opposed formal depth-dependent separation layers. The results allowed us trace relationship between peculiarities podzolic well indicators drivers primary
