and Ph.D. degrees. Soils and Biogeochemistry focuses on the study of physical, chemical, and biological processes in the diverse soils of a variety of landforms and ecosystems. The goal is to understand the complex processes of mass and energy flow that control agricultural and natural ecosystem functions, productivity, and sustainability. Research projects also explore impacts and implications of
both natural and anthropogenic activities—notably climate change, land use change and pollution—on soil at different scales, from the plot to ecosystems, landscapes, regions, and the planet. Topics of study include: mechanisms and monitoring of greenhouse gas emissions; pesticide and trace element adsorption on surfaces; mineral weathering; fate and transport of native and applied chemicals; soil microbial ecology; soil carbon sequestration; nutrient uptake and management; nutrient cycling through managed and wildland ecosystems; organic agriculture; above and below-ground biodiversity; soil erosion; conservation; ecosystem productivity and sustainability; role of soil in ecosystem services; and the study of soil evolution on the landscape. These studies are carried out within a framework of integrating the chemical, physical, and biological sciences that constitute the study of soils and biogeochemistry and often reflect a rich history of collaborating with . The Soils and Biogeochemistry program at UC Davis offers a unique opportunity to investigate soils throughout the diverse regions of California, in the US, and globally in a number of international projects. Studies target agricultural, forest and grassland, coastal, wetland and urban ecosystems.
