Könönen et al 2012: Land-Use Changes Tropical Peat Characteristics
Theme IX. Tropical peatlands
Tropical peatlands are vast carbon stores and subjects of quickly advancing man made deforestation and drainage. In this study we clarified the impacts of land use change on the physical and chemical properties of tropical peat in Central-Kalimantan, Indonesia. For physical characteristics we determined peat bulk density and fractioned particle size distribution, and for chemical characteristics we analyzed extractives, holocellulose (cellulose and hemicelluloses), acid soluble lignin, Klason’s lignin, ash and total carbon and nitrogen content. The study showed that the bulk density and content of decomposition resistant lignin like compounds increased after land use change.
