The carbon and macroelement budget in the bog ecosystems of the middle taiga in Western Siberia

Abstract

The article provides quantitative values of the main biological processes and experimental data for the production and destruction processes and the process of translocation. There are considered data on carbon, nitrogen and potassium element storages in the phytomass, mortmass and bog ecosystem production of the middle taiga in Western Siberia. Storages of elements are determined by their concentration in different fractions of ecosystem plant matter. In the bog ecosystems N, K and Mg decrease by two and three times while transporting from phytomass into mortmass and P and Ca are accumulated in mortmass. There is a great difference in element concentrations in phytomass in different ecosystem types. Element storages are determined by phytomass volume much more than on concentration and increase in ecosystem line: oligotrophic hollows → ridges. All these features depend on species composition of the community and on chemical composition of predominant plants.
