Enhanced weathering in acid and alkaline agricultural soils: greenhouse gas emissions and soil bacterial communities implications

Sílvia Poblador, Coline Le Noir de Carlan, Erik Verbruggen, Sara Vicca Abstract Changes in agricultural management practices to enhance soil carbon (C) sequestration while maintaining crop productivity are a key opportunity to reduce the impact of humans on the environment, reducing greenhouse gas (GHG) fluxes to the atmosphere and nutrient leaching to aquatic ecosystems without compromising food and soil security. Amongst them, enhanced weathering (EW) of silicate minerals is a promising negative emission technology that can be associated with multiple co-benefits for crop production by spreading silicate minerals on arable soils (i.e. ...
