BG3.34 | Understanding trade-offs between SOC stocks and GHG emissions for climate-smart soil management
Understanding trade-offs between SOC stocks and GHG emissions for climate-smart soil management
Convener: Ana Meijide | Co-conveners: Mari Pihlatie, Peter Dörsch, Jorge Perez-Quezada, Bruce Osborne
Management practices such as reduced or no tillage, cover crops, and incorporating organic amendments, are increasingly implemented to sequester additional carbon in agricultural soils. However, the persistence and vulnerability of the freshly incorporated carbon remains unclear. Additionally, management practices that increase SOC may induce additional greenhouse gas (GHG) emissions, particularly nitrous oxide (N2O).
This session will assess the trade-offs between management practices aimed at increasing SOC sequestration in agricultural soils and GHG emissions, with the goal of achieving true climate-smart soil management. We invite contributions exploring trade-offs under different management practices, soil types, and climatic conditions, and assessing the mechanisms responsible for them. We are seeking contributions from all pedo-climatic zones, using both measurement and modeling approaches which quantify GHG fluxes and SOC stocks and their trade-offs.
