Adding Crushed Volcanic Rock to Farm Soil Could Boost Crops and Slow Global Warming

Read the full story at Civil Eats.

Pulverizing volcanic rock and spreading the dust like fertilizer on farm soils could suck billions of tons of carbon from the atmosphere and boost crop yields on a warming planet with a growing population.

In a paper published recently in the scientific journal Nature Plants, an international team of researchers lays out the prospects for “enhanced rock weathering”—a process that uses pulverized silicate rocks, like basalt, to speed the ability of minerals to store carbon in soil.
