Abstract
Achieving national targets for net-zero carbon emissions will require atmospheric carbon dioxide removal strategies compatible with rising agricultural production. One possible method for delivering on these goals is enhanced rock weathering, which involves modifying soils with crushed silicate rocks, such as basalt. Here we use dynamic carbon ...
Effects of mineralogy, chemistry and physical properties of basalts on carbon capture potential and plant-nutrient element release via enhanced weathering
Amy L.Lewis, Binoy Sarkar, Peter Wadea, Simon J.Kemp, Mark E.Hodson, Lyla L.Taylor, Kok Loong Yeong, Kalu Davies, Paul N.Nelson, Michael I.Bird, Ilsa B.Kantola, Michael D.Masters, Evan DeLucia, Jonathan R.Leake, Steven A.Banwart, David J.Beerling
Abstract
Mafic igneous rocks, such as basalt, are composed of abundant calcium- and magnesium-rich silicate minerals widely proposed to be suitable for scalable carbon dioxide removal (CDR) by enhanced rock weathering (ERW). Here, we report a detailed characterization of the mineralogy, chemistry, particle size and surface area of six mined basalts being used in large-scale ERW field trials. We use 1-D ...
Increased yield and CO2 sequestration potential with the C4 cereal Sorghum bicolor cultivated in basaltic rock dust-amended agricultural soil
Mike E. Kelland, Peter W. Wade, Amy L. Lewis, Lyla L. Taylor, Binoy Sarkar, M. Grace Andrews, Mark R. Lomas, T. E. Anne Cotton, Simon J. Kemp, Rachael H. James, Christopher R. Pearce, Sue E. Hartley, Mark E. Hodson, Jonathan R. Leake, Steven A. Banwart, David J. Beerling
Abstract
Land-based enhanced rock weathering (ERW) is a biogeochemical carbon dioxide removal (CDR) strategy aiming to accelerate natural geological processes of carbon sequestration through application of crushed silicate rocks, such as basalt, to croplands and forested landscapes. However, the efficacy of the approach when undertaken with basalt, and its potential co-benefits ...
The role of enhanced rock weathering deployment with agriculture in limiting future warming and protecting coral reefs
Negar Vakilifard, Euripides P Kantzas, Neil R Edwards, Philip B Holden and David J Beerling
Abstract
Meeting the net-zero carbon emissions commitments of major economies by mid century requires large-scale deployment of negative emission technologies (NETs). Terrestrial enhanced rock weathering on croplands (ERW) is a NET with co-benefits for agriculture, soils and ocean acidification that creates opportunities for generating income unaffected by diminishing carbon taxes as emissions approach net-zero. Here we show that ERW deployment with croplands to deliver net 2 Gt CO2 yr−1 removal approximately doubles the probability of meeting the Paris ...
