Microbiological parameters and peat stratigraphy of two types of bogs in the northern part of the Sym–Dubches interfluve (Krasnoyarsk Krai)

The phytocenotic and microbiological features of two types of bogs (oligotrophic and eutrophic) in the northern part of the Sym–Dubches interfluve (the middle taiga subzone in the Yenisei region of Siberia) have been studied. The descriptions of the plant cover of bogs and peat stratigraphy and age are given. It has been revealed that peat of the bogs studied is characterized by a low or medium ash content; a small amount of N, P, and K; and an acid and slightly acid reaction, which results in their moderate microbial and fermentation activity and favors accumulation and conservation of plant remains and microbial biomass. It has been proved that the microbocenoses of the eutrophic and oligotrophic bogs are characterized by a stable ecophysiological status of the natural norm
