Advanced Soil Science and Isotope Geochemistry
The course teaches state-of-the art principles and methodologies interfacing soil science and the field of isotope geochemistry. The course emphasizes the connection between fundamental processes in soils (C, N cycling), vegetation and application of stable isotope techniques to unravel the link between terrestrial processes and atmosphere.
Accordingly, the course focuses on modern concepts of soil biogeochemical functioning and explains advanced state-of-the art experimental and technical approaches to unravel soil processes to understand soil functions in natural and managed soils. The course has a particular focus on application of advanced stable isotope analysis as tracers of geochemical and biological processes in terrestrial systems as a mean to establish knowledge on the interaction between physical and chemical environment and human activity.
The course includes practical exercises with soil and air isotopic analysis.
