Landscape processes: Soil water and solute transport processes at different spatial and temporal scales are one focus of our group. We investigate transport processes in well-drained silt-loam soils, and are interested in the impact of soil management on transport processes, their scale dependence, spatial correlation length and association to other soil properties. Another focus is the investigation of spatio-temporal biomass development in farmers' fields. We describe the spatial pattern of biomass during the growing season based on crop sensor observations in combination with stochastic models.
