Plant-Soil Interactions in the Rhizosphere: Experimental and Computational Advances II Posters

Submit an Abstract to this Session



Session ID#: 22837

Session Description:
The rhizosphere is a critical element in the soil-plant-atmosphere continuum (SPAC) with influences far beyond its microscale origins. Formed as a result of root physical growth through the soil profile and root exudates, the rhizosphere sustains a structural and chemical environment favorable to microbes, bacteria, and mycorrhizae. These microscale communities significantly alter soil structure, moisture, hydraulic conductivity, and root-soil exchanges, with and macro/field-scale consequences on plant growth and development, soil biogeochemistry, soil-water dynamics and agricultural stability. We invite presentations that highlight and advance the coupled micro/macroscale processes and functions of the rhizosphere. Field, laboratory, advanced imaging and modeling studies from the micro- to macroscale are welcome - topics taking an integrated and cross-disciplinary approach are highly encouraged. The goal of this session is to create an interdisciplinary forum through which plant scientists, ecologists, soil scientists, biogeochemists, and microbiologists can investigate coupled biophysiochemical processes highlighting the myriad activities of the rhizosphere.
