Features of development of soil microbial complexes after pyrogenic factor influence

Annotation

The qualitative and quantitative composition of different physiological groups of soil microorganisms were studied after fires of different intensity in forests of Central Black-Earth region. It is established, that the impact on soil microbial complexes depends on the intensity of the fire. The fires of moderate and particularly high intensity had negative influence on the structure and functional activity of soil microbial complexes.

Keywords

forest fire; soil microbial complexes; prototrophs; oligonitrophilous; ammonifiers.
