Volcanic rock spread on farms may capture carbon

Enhanced rock weathering spreads crushed volcanic rock like basalt on farmland to accelerate natural carbon capture.

Rainwater reacts with basalt to convert atmospheric CO₂ into stable bicarbonate ions that are stored in oceans.

Basalt releases essential nutrients such as calcium, magnesium, potassium, and silica, improving soil health and crop yields.

Field experiments suggest significant carbon removal potential alongside agricultural benefits.

Ongoing research aims to verify effectiveness and integrate farms into carbon removal strategies.
