Can Rock Dust Soak Up Carbon Emissions? A Giant Experiment Is Set to Find Out

The idea of sprinkling rock dust on farmland to soak up atmospheric carbon will be tested at large scale, thanks to a $57 million purchase from corporations including Stripe and Alphabet.

Farmers are using volcanic rock dust to sequester carbon and improve soil health. The rock dust reacts with carbon dioxide and water to form stable minerals that store carbon for millennia. This could help mitigate climate change, enhance crop yields, and reduce fertilizer use.

How sprinkling volcanic rocks on farmland could capture carbon dioxide

Scientists found that applying basalt dust in croplands can effectively sequester atmospheric carbon dioxide at the gigaton scale.

I've read about this before: spreading #rockdust on #farmland to pull #CO2 out of the atmosphere

Seems a lot more sensible than stratospheric aerosol injection.
