摘要

Regular fires on drained peatlands widespread in the taiga and forest-steppe zones are especially dangerous and destructive under Polesiye landscape conditions [1, 2]. They have relatively shallow peat layers 1-2 m deep underlain by a thick gleyed,almost barren, fine- and medium-grained water-bearing sand. After fires, secondary pyrogenic formations and pyrogenically altered soils are developed on the burnt bog surface. Pyrogenic formations are characterized by low fertility and subjected to strong secondary waterlogging. Therefore, the pyrogenic degradation of peat soils is an urgent economic problem [3, 4].Actinomycetes are an essential component of the microbial complex of peat soils. The actinomycete complex of peat soils has specific features differing from those typical for mycelial prokaryote complexes in zonal soils. The actinomycete complex serves as an index of changes occurring in the microbial community in the course of peat production for fuel and fertilizers followed by the restoration of worked-out lands [5].The aim of this work was the comparative study of actinomycete complexes developed in undisturbed low-moor peat soil and pyrogenic formations on burnt peat soils for determining the possibility of using the parameters of the soil actinomycete complex asan index of changes occurring in the microbial community of a soil on its transformation into a pyrogenic formation.
