Sonja Leitner

I am an ecologist and biogeochemist working on carbon and nitrogen cycling in natural and agricultural ecosystems. I investigate nutrient transformations and nutrient losses via leaching and gaseous emissions, with a special focus on greenhouse gas emissions (CO2, CH4, N2O). Currently, my research focuses on options for soil and manure management that reduce nutrient losses to improve livestock productivity and help to mitigate climate change. I work in both mixed crop-livestock systems as well as rangelands and am currently involved in projects in Kenya, Ethiopia, Uganda, and Burkina Faso.
