UK Study Explores Enhanced Weathering for Absorbing Carbon Dioxide in Agricultural Soil

Scientists at the University of Sheffield have published a study that says adding rock dust to UK agricultural soils could absorb up to 45% of the atmospheric carbon dioxide needed to reach net zero. The study found that enhanced weathering produces rock dust that can be added to agricultural soils, removing atmospheric carbon dioxide, mitigating nitrous oxide production, and substituting for imported fertilizers. Lead author Dr. Euripides Kantzas of the Leverhulme Centre for Climate Change Mitigation at the University of Sheffield said, “By quantifying the carbon removal potential and co-benefits of amending crops with crushed rock in the UK, we provide a blueprint for deploying enhanced rock weathering on a national level, adding to the toolbox of solutions for carbon-neutral economies.”
