131 Symposium--Soil Minerals in Natural and Agroecosystems: I

Oral Session
S09 Soil Mineralogy

Mineralogy plays an important role in agricultural and natural ecosystems. It is often assumed that soil mineralogy is insensitive to changes in vegetation, land use and management practices because it is an inherent soil property. Evidence in recent decades has challenged this tenet and shown that management practices such as prescribed burning, fertilization and vegetation selection or control can alter soil minerals. This symposium will bring together scientists working in agroecosystems and natural systems to explore how management impacts soil mineralogy. This is a timely pursuit given the importance of soil minerals in carbon sequestration and soil productivity.
