151 Symposium--Mineral-Organic Interactions Across Time and Space: I & II

Oral Session
S09 Soil Mineralogy The interaction of organic components with inorganic solid-phases is as an important regulator of biogeochemical processes at nano- to landscale scales. Organo-mineral interactions are implicated in carbon stabilization, regulating mineral transformation rates, creating reactive surface sites, and structuring microbial communities. We seek to enhance collaborative connectivity between scientists studying these processes at molecular to landscape scales. Topics will include novel coupling of molecular, isotopic, or imaging techniques to quantify organo-mineral interactions, to pedon or landscape studies of organic-mineral associations across pedogenic gradients and spatially-linked landscape sequences. Studies investigating organic-mineral interactions in micro or mesocosm space are equally encouraged.
