Applying rock dust to croplands could absorb up to 2 billion tons of CO2 from the atmosphere University of Sheffield via Phys.org Adding crushed rock dust to farmland could draw down up to two billion tons of carbon dioxide (CO2) from the air per year and help meet key global climate targets, according to a major new study led by the University of Sheffield. The technique, known as enhanced rock weathering, involves spreading finely crushed basalt, a natural volcanic rock, on fields to boost the soil's ability to extract CO2 from the air. READ MORE
