Scientists are applying crushed volcanic rock, specifically basalt, to agricultural land as a method to accelerate natural carbon capture processes. By spreading the rock across farm fields, the material reacts with rainwater to convert atmospheric carbon dioxide into stable bicarbonate ions, which can be stored in the environment for long periods.
This process, known as enhanced rock weathering, serves a dual purpose by also releasing essential nutrients into the soil. Field experiments indicate that the application can improve overall soil health and increase crop yields. Researchers are currently evaluating the method's potential to contribute to large-scale carbon removal efforts.
