Climate change affects the dynamic feedbacks among plants, soil, and microbial communities, and thus strongly influences terrestrial biogeochemical cycling. In this session we address the question: What is the impact of changing environmental conditions on the plant-microbe-soil system, and what are the resulting effects on soil biogeochemistry? Given the positive and negative feedbacks with the climate system, dynamics of soil organic matter across terrestrial ecosystems are a key focus of this session.
We invite contributions from manipulative field experiments, observations in natural-climate gradients, and modeling studies that explore the climate change impacts on plant-soil interactions, biogeochemical cycling of C, N, P, microbial diversity and decomposition processes, and deep-soil biogeochemistry. Submissions that adopt novel approaches, e.g. molecular, isotopic, or synthesize outputs from large-scale, field experiments focusing on plant-soil-microbe feedbacks to warming, wetting, drying and thawing are very welcome.
This is the continuation of our 2023 and 2024 successful session on the same topic and focus. We would like to continue bringing people together with this session in order to learn from each other’s studies on soils and climate change from a global range of pedogenic and environmental settings.
