Paper Title
Fluxes of Dissolved Organic Carbon and Nutrients Leaching in Toposequent of Bukit Dua Belas National Park, Indonesia

The study of dissolved organic carbon (DOC) and nutrients leaching fluxes from soil profiles has important impacts to the quality of soils and the environment. This research was conducted in lowland secondary tropical forest of the Bukit Dua Belas National Park, Jambi Province, Indonesia. The research site was appropriated toposequent transect divided into three soil profiles in upper, middle, and lower slopes. The research results indicated that fluxes of DOC leaching of the lower slope was significantly higher compare to that of the middle and the upper slopes. Similarly, fluxes of nutrients leaching of AO soil horizon was higher compare to that of lower soil horizons. There were significant positive correlations between nitrate, phosphate, sulphate, chloride, and borate anions with calcium, magnesium, potassium, and ammonium cations. DOC leaching flux also has significant positive correlations with these ions. Keywords- Lowland Secondary Tropical Forest, Flux. DOC, Cations, Anions.
