Thursday, February 11, 2021 - 10:45 to Friday, February 26, 2021 - 10:45

Dear all, We would like to draw your attention to session 9f "Role of plants and/or microbes in weathering dynamics and biogeochemical cycles" at Goldschmidt 2021 in Lyon, France, from June 4-9 July this year. We are hoping to bring together researchers from various backgrounds shedding light on microbial and plant impacts on weathering, carbon, nutrient, contaminant, and water fluxes within ecosystems stimulating fruitful discussions and ground-breaking follow-up research.

We offer an exciting and diverse lineup of keynote and invited speakers with Dr. Heather Buss (University of Bristol, UK), Dr. Christina Kaiser (University of Vienna, Austria) and Dr. Eva Oburger (BOKU, Austria). We encourage theoretical, experimental, and field study contributions focused on the impact of plant roots and microbial communities on weathering and biogeochemical cycles.

Abstract submission deadline is Friday, February 26th. For further information on abstract and submission process, please have a look here: https://2021.goldschmidt.info/goldschmidt/2021/cfp.cgi. The conference will partially be in-person and virtual.

Feel free to share this announcement with your colleagues and collaborators.

Looking forward to seeing you in Lyon or on screen,
Convener team for session 9f: Sétareh Rad, E. Marie Muehe, Bhavna Arora, Vincent Milesi, Marco Keiluweit and Steven Yabusaki


Session 9f: "Role of plants and/or microbes in weathering dynamics and biogeochemical cycles"

The Earth’s surface is modulated by interactions between plants and microorganisms with water, rock, and soil that result in weathering processes controlling biogeochemical cycles (e.g. C, S, N, P, Fe) from micro to global scales, from daily to geological timescales. To estimate weathering and related impacts on carbon, nutrient, contaminant, and water balances within ecosystems, it is crucial to understand the myriad ways in which plant roots and microbial communities shape their geochemical environment. In contrast, geochemical conditions influence plant and microbial functioning in response to the availability of water and nutrients, changing climate and land use, and exposure to pests and pollutants.

In this session, we aim at interrogating the biogeochemical controls of weathering dynamics and biogeochemical processes, how they respond to environmental changes, and how they shape and are shaped by microbial and plant habitats on Earth. We encourage theoretical, experimental, and field study contributions focused on the impact of plant roots and microbial communities on weathering and biogeochemical cycles. Contributions that employ new observational, experimental, field study, analytical and modeling approaches and theoretical frameworks to investigate processes as varied as water fluxes, pore structure, redox processes, mineral uptake or organic-mineral interactions in the rhizosphere and at microbial hot spots and hot moments are welcome.
