Objectives

• Assessment of changes in stock, budget and quality of C in heavily weathered soils after conversion of lowland rainforest to three transformation systems (Jungle rubber, Rubber plantation, Oil palm plantation)


• Evaluation of mechanisms of C sequestration with special focus on DOM fluxes within whole soil profile by four land use systems and evaluation of changed turnover of SOM and microbial biomass


• Assessment of changes of functions of stored C by evaluation of microbial activities
