AGU 2025 - We’re hosting a session: GC13K Reducing Uncertainty and Operationalizing MMRV for Soil Carbon and Nitrous Oxide on Working Lands I (Oral)

From rigor to real-world impact: models, measurements, and policy in concert

The Big Idea: We’re moving from isolated tools and datasets to an interoperable, evidence-driven foundation for climate-smart agriculture—uniting modelers, field scientists, and policy innovators.

AGU fall meeting: MONDAY, December 15th, 8:30 - 10:00 AM New Orleans

Why this session

  • See measure-and-remeasure designs to ground our science

  • Learn how national soil networks and field programs operationalize MMRV

  • Understand uncertainty: variability, calibration choices, and Bayesian ensembles

Speaker lineup (in order)

  • Prateek Sharma (Michigan State University) A multimodel hybrid for estimating N₂O mitigation from regenerative practices—bridging simulations and field-level management.

  • Mark Bradford (Yale) with EDF & Illinois collaborators Causal measure-and-remeasure: experimental design and transparent data to strengthen soil-carbon crediting.

  • Senani Karunaratne (Australia: CSIRO, Murdoch Univ., and partners) National-scale insights: statistically significant SOC shifts across agricultural landscapes and what they mean for monitoring networks.

  • Martha Farella (Yard Stick) Resampling variability in Midwestern soils—the overlooked driver of uncertainty in MMRV.

  • Negar Tafti (The Nature Conservancy) From framework to field: implementing MMRV across programs in the U.S., India, and Tanzania.

  • Beth Ziniti (Regrow Ag) Model choices matter: structure, calibration, and data harmonization shape GHG estimates.

  • Stephen Ogle (CSU) with KIT & Aarhus University Reducing uncertainty in N₂O: process-based model ensembles within a Bayesian framework.
