SUMMARY

The carbon chemistry largely determines the decomposability of organic substrate. The advanced knowledge of tropical peat organic carbon chemistry (OCC) improves understanding of carbon dynamics, which is needed for sustainable management of these ecosystems. Yet, tropical peat OCC is a highly understudied subject. To study tropical peat OCC we gathered samples from undrained peat swamp forest and three other land uses altered 20–30 years prior to the study, which together form a continuum of increasing landuse intensity. From studied peats collected from in CentralKalimantan, Indonesia, the OCC, i.e. the hemicellulosic carbohydrate and uronic acid…
