Using model ensembles to assess long term changes in temperate grasslands SOM and associated C&N fluxes

Carbon (C) sequestration in soils constitutes a key action to mitigate climate change and to improve food security, by enhancing soil quality and resilience. Co-benefits resulting from soil organic C (SOC) sequestration, adaptation and mitigation practices should be tested to assess their impacts. Contrasted process-based models, integrating C, nitrogen and water dynamics within soil-plant-atmosphere systems are used to predict agricultural greenhouse gas (GHG) emissions, yield and soil organic carbon (SOC) stocks.
