ALGO-COMMUNITY AND MICROCOMMUNITY PARTICIPATING IN NITROGEN CYCLE OF SOD-PODZOLIC SOIL IN YOUNG TAIGA ECOSYSTEM OF TOMSK REGION
Abstract
The paper reveals the algae and nitrogen-fixing microorganisms in sod-podzolic soil of young taiga ecosystems are developed in surface soil layer. Algoflora of sod-podzolic soil in young taiga ecosystem is characterized by low ecosystem diversity, dominance of Сhlorophyta monadiforms, exactly Chlamydomonas ubiquists and species and some of Суапорrocaryotophyta. The domination complex includes green algae species. The publication shows the soils of taiga ecosystem differ in low amount of algae; aerobic oligonitrophilic microorganisms, anaerobian Clostridium bacteria and Cyanobacteriae provide biological nitrogen-fixing. Concentration of ammonifiers in sod-podzolic soil is high; nitrifying agents’ concentration in sod-podzolic soil is low. Denitrifying agents are observed in the soil.
