Session Description: Microorganisms, roots and associated fungal symbionts drive mineral weathering and extent throughout the Critical Zone (CZ) by acting as conduits for water and nutrient flow and through production of organic acids. Advances in process-based models, isotopic-, image-, and “-omics”-based approaches reveal the contribution of life interacting with primary rock mineral materials resulting in soil formation, expanding our understanding of the depth of the CZ. The feedbacks between biological weathering, transport, porosity generation, and solute fluxes within the subsurface environment at varying spatiotemporal scales remains to be explored.  How are microbially-mediated transformations governed by vadose zone architecture, rock/soil fracture/matrix hydraulic pathways, and the presence of roots? How can we better elucidate biological controls on chemical weathering? We seek cross-disciplinary studies that are utilizing modeling approaches and integrating novel data sets to understand the interactions and feedbacks between roots, microorganisms, nutrients, water and minerals on varying spatiotemporal scales throughout Earth’s Critical Zone.
