Land use change in Amazonian Dark Earth and Acrisol: responses of organic carbon, organic matter composition and microbial carbon utilisation.

Land use change in Amazonian Dark Earth and Acrisol: responses of organic carbon, organic matter composition and microbial carbon utilisation.

The conversion of tropical forest for cassava cultivation is widely known to decrease the soil organic matter (OM) and nutrient contents of highly weathered soils in the tropics. Amazonian Dark Earth (ADE) might be affected less due to their historical anthropogenic amelioration with e.g. charcoal, ceramics and bones, leading to higher soil OM and nutrient concentrations. In this study, we analysed the effect of land use change on the OM dynamics and its composition under tropical conditions, using ADE and an adjacent Acrisol (ACR) as model systems.
