Abstract
Enhanced weathering (EW) with crushed basalt on farmlands is a promising
scalable atmospheric carbon dioxide removal strategy that urgently requires
performance assessment with commercial farming practices. Our large-scale
replicated EW field trial in the heart of the U.S. Corn Belt shows cumulative time integrated carbon ...

Restricting future global temperature increase to 2°C or less requires the adoption of negative emissions technologies for carbon capture and storage. We review the potential for deployment of enhanced weathering (EW), via the application of crushed reactive silicate rocks (such as basalt), on over 680 million hectares of tropical agricultural and tree plantations to offset fossil fuel CO2 emissions. Warm tropical climates and productive crops will substantially enhance weathering rates, with potential ...
