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