Adding crushed rock dust to farmland has the potential to remove and lock up large amounts of carbon dioxide from the atmosphere. In the first trial of Enhanced Rock Weathering on upland grasslands in the world, UKCEH scientists applied 56 tonnes of finely ground basalt rock from quarries to three hectares of farmland in Plynlimon, Powys in May 2023 and will repeat this at the same time in 2024.
The basalt rock dust particles, which are less than 2mm in size, absorb and store carbon at faster rates than occur with the breaking down, or weathering of the naturally occurring rocks at the sites, reducing the timescale from decades to just months.
