Kantola, Ilsa B.; Masters, Michael D.; Beerling, David J.; Long, Stephen P.; DeLucia, Evan H. (2017): Potential of global croplands and bioenergy crops for climate change mitigation through deployment for enhanced weathering. In Biology letters 13 (4). DOI: 10.1098/rsbl.2016.0714[nbsp]

„Enhanced weathering (EW) in agricultural soils—applying crushed silicate rock as a soil amendment—is a method for combating global climate change while increasing nutrient availability to plants. EW uses land that is already producing food and fuel to sequester carbon (C), and reduces N₂O loss through pH buffering. As biofuel use increases, EW in bioenergy crops offers the opportunity to sequester CO₂ while reducing fossil fuel combustion. Uncertainties remain in the long-term effects and global implications of large-scale efforts to directly manipulate Earth’s atmospheric CO₂ composition, but EW in agricultural lands is an opportunity to employ these soils to sequester atmospheric C while benefitting crop production and the global climate.“
