Contribution of dissolved organic carbon to total alkalinity in Enhanced Weathering experiments

Puntos clave

• Total alkalinity increases with higher dissolved organic carbon concentrations, enhancing carbon sequestration.
• Key evidence shows a significant correlation, with up to 30% of total alkalinity attributed to dissolved organic carbon in specific conditions.
• Observational analysis across multiple experiments illustrates how enhanced weathering processes interact with dissolved organic carbon levels.
• This may highlight new strategies for carbon management and climate change mitigation efforts, though further studies are needed.
