Abstract: Farmland enhanced rock weathering (ERW) is a negative emission technology that accelerates CO2 sequestration into the soil inorganic carbon (SIC) sink by applying calcium and magnesium-rich silicate rock to agricultural soils. Farmland ERW has great CO2 removal potential and is accompanied by various co-benefits, such as improving soil pH and providing mineral nutrients. However, the environment-driven mechanisms of ERW remain unclear, and the uncertainty on crop productivity also requires further evaluation in field trials.
