High-latitude ecosystems store approximately 1700 Pg of soil carbon (C), which is twice as much C as is currently contained in the atmosphere. Permafrost thaw and subsequent microbial decomposition of permafrost organic matter could add large amounts of C to the atmosphere, thereby influencing the global C cycle. The rates at which C is being released from the permafrost zone at different soil ...

Abstract Purpose The aim of this work was to determine the characteristics SOM decomposition under forest vegetation and investigate influence soil mineralogy on turnover. Methods Thirteen Hungarian topsoil samples amended with maize residues were incubated at 20 °C for 163 days. CO 2 evolved measured fast slow rate constants (k 1 k , respectively) quantified using a first-order two pools model...
