Session Proposal: Biogeochemical Coupling In Terrestrial Ecosystems: Synthesizing Across Scales and Disciplines (AGU25)

B019
Biogeochemical Coupling In Terrestrial Ecosystems: Synthesizing Across Scales and Disciplines

Session ID#: 252698

Session Description:
Interactions between carbon (C) and nutrient cycling in managed and unmanaged ecosystems shape ecological responses to global change, yet the direction and strength of these interactions remain poorly understood. Additionally, scaling these biogeochemical linkages is not always intuitive, creating uncertainty about our understanding of, and model parameterizations for, Earth Systems. For example, recent work has focused on the fate of terrestrial C without sufficient emphasis on its interaction with other nutrient cycles in multiple spatial and temporal dimensions, limiting our ability to simulate C-nutrient-climate feedbacks and identify sustainable practices for land managers. Experimental, observational, and synthetic research that examines C-nutrient linkages is a crucial step in filling these knowledge gaps and parameterizing models. We welcome abstracts that share observational, experimental, and/or modeling research, conducted at local to global scales, to advance our understanding of the effects of nutrient imbalances, interactions, and constraints on biogeochemical cycles.
