14 C Dating and Soil Organic Matter Dynamics in Arctic and Subarctic Ecosystems
The carbon content, pH and 14 C concentration of humic acids were determined for three soil series of Arctic and Subarctic ecosystems. The measured 14 C ages were interpreted in the light of an equilibrium model of humus formation and of mineralization processes in recent soils, and the coefficient...

| Summary: | The carbon content, pH and 14 C concentration of humic acids were determined for three soil series of Arctic and Subarctic ecosystems. The measured 14 C ages were interpreted in the light of an equilibrium model of humus formation and of mineralization processes in recent soils, and the coefficient of renovation, K r , was calculated for humic acids. The comparison of K r for series formed under different climatic conditions suggested that global warming could accelerate decomposition of soil organic matter and possibly increase productivity of ecosystems of the Arctic region. |
