S02 Soil Chemistry The interactions of organic components with inorganic solid-phases is recognized as an important regulator of biogeochemical processes operating from the nano- to landscale scales. Organo-mineral interactions are implicated in carbon stabilization and persistence, in regulating mineral transformation rates, creating reactive surface sites and in structuring microbial communities. Here we seek to enhance collaborative connectivity between scientists studying these processes at the molecular and pedon or landscape scales. We propose a joint full-day symposium by S-9 and S-2 with potential co-sponsorship by S-3 and S-5. Examples of presentation topics include novel coupling of molecular, isotopic, or imaging techniques to quantify organo-mineral interactions to pedon or landscape studies of carbon or organic-mineral associations across pedogenic gradients, watersheds, and spatially-linked landscape sequences. Studies investigating spatial or temporal variation in organic-mineral interactions in micro or mesocosm space are equally encouraged.
