Abstract
The population of saprotrophic, oligotrophic, and nitrogen-fixing microorganisms was determined in cryogenic forest soils of central Yakutia. The number of saprotrophic bacteria ranged between 108 and 1010 cell/g of soil. In the soils of Buryatia, this parameter (108) was 4 orders of magnitude as high as in the soils of European Russia (106). According to the increase in the total number of microorganisms in the soils studied, the forests were arranged in the following sequence: pine forest—birch forest—larch forest. The main factor that determined the saturation of the studied frozen soils with microorganisms was the landscape, i.e., the forest type and the soil type. Of minor importance were the weather conditions of the year or season investigated, which defined the intra-and interspecies variation of the total population of the soil microorganisms.
