CO2 sequestration by Enhanced Weathering of agricultural soils in Norfolk, UK

Enhanced Weathering (EW) of silicate rocks is a carbon dioxide (CO 2 ) removal (CDR) strategy whereby powdered rock is applied to the land and/or ocean in order to mitigate climate warming through accelerated rates of chemical weathering. Agricultural sites are particularly suited for EW as they host infastructure needed to implement EW, and the nutrients released during weathering facilitate a number of food security co-benefits such as increased crop yields [1]. Here we present results from EW field trials conducted in Norfolk, United Kingdom, with two different crops, namely peas and sugar beet. The field site features sandy, quick- draining ...
