Abstract

Elemental cycling is critical to the function of ecosystems and delivery of key ecosystem services because many of these elements are essential nutrients or detrimental toxicants that directly affect the health of organisms and ecosystems. Soil biogeochemical processes control the transformation, fate, and transport of elemental species in soils. In this chapter, we describe the biogeochemistry of carbon, nitrogen, and phosphorus, with an emphasis on the physical, chemical, and biological processes that drive their cycling at the microscopic to global scale. Additionally, how soils control the fate and transport of metals and synthetic organic chemicals in the environment is characterized. In an additional effort to provide transparent connections to the real world, case studies are presented to illustrate how proper management of soils can foster key biogeochemical processes to maximize ecosystem services and address current environmental issues. This chapter provides the background needed for an informed public to gain understanding of the multitude of soil biogeochemical functions and how soil provides and regulates services to society.
