Soil is the interface between biological, atmospheric, and geologic systems. Movement of heat, water, and chemical in soil impacts the terrestrial environment at nearly every scale. Research efforts focus on understanding principles of this movement through laboratory and field experiments, development of new measurement techniques, and numerical modeling.
Major research goals are to detail soil water and energy budgets for evaporation and evapotranspiration, improve efficiency and services of agricultural, urban, and marginal soils, and develop theoretical frameworks and measurement systems to quantify soil processes.
