Research interests
My research has been focused on how the management of small scale agricultural systems in the tropics influences the biogeochemical processes of the soil and vice versa. My current research aims to assess the influence of land use, agricultural management and inherent soil properties, in particular soil texture and clay mineralogy on the storage and the decomposition of soil organic carbon (SOC) in tropical soils. Within this context field work has been carried out in Ghana and is to be carried out in the Solomon Islands. The field data will be combined with laboratory analyses and experiments to construct a model that expresses the relationships between land use, soil parameters and carbon stocks and turnover rates in common low-input tropical agricultural systems
