It should be noted, that pedogenesis reconstructions obtained on the base of
microbiological methods are in full accord with those obtained with the help of
traditional morphological-genetic analysis of the soils. Moreover, being more
sensitive to soil-forming condition changes, the data of microbial community state
allows to specify and work out in detail the morphological-genetic analysis data.
