Spreading crushed basalt dust in the fields
Undo
Projects that spread rock dust on farms are removing more carbon dioxide from the atmosphere than competing technologies, but CO2 removal efforts fall far short of preventing dangerous levels of global warming.
Known as enhanced rock weathering, the method involves spreading crushed volcanic rock over fields to speed up the natural weathering process that turns atmospheric CO2 into stable minerals. Driven by its relative simplicity, and new evidence of what rock dust can do improving crop yields as well as carbon sequestration – this…
