Modeling the evolution of natural cliffs subject to weathering. 2, Discrete element approach [PDF]

, 2011
The evolution of slopes subjected to weathering has been modeled by assuming Mohr-Coulomb behavior and by using a numerical approach based on the discrete element method (DEM).

Climate change mitigation: potential benefits and pitfalls of enhanced rock weathering in tropical agriculture. [PDF]

Biol Lett, 2017
Restricting future global temperature increase to 2°C or less requires the adoption of negative emissions technologies for carbon capture and storage. We review the potential for deployment of enhanced weathering (EW), via the application of crushed reactive silicate rocks (such as basalt), on over 680 million hectares of tropical ...

Quantification of CO2 removal in a large-scale enhanced weathering field trial on an oil palm plantation in Sabah, Malaysia

Frontiers in Climate, 2022
Modeling studies show that large-scale deployment of enhanced rock weathering on croplands has the potential to reduce levels of atmospheric carbon dioxide by the end of the century.

Carbon Dioxide Efficiency of Terrestrial Enhanced Weathering [PDF]

, 2014
Terrestrial enhanced weathering, the spreading of ultramafic silicate rock flour to enhance natural weathering rates, has been suggested as part of a strategy to reduce global atmospheric CO2 levels.

Increased carbon capture by a silicate-treated forested watershed affected by acid deposition [PDF]

Biogeosciences, 2021
Meeting internationally agreed-upon climate targets requires carbon dioxide removal (CDR) strategies coupled with an urgent phase-down of fossil fuel emissions. However, the efficacy and wider impacts of CDR are poorly understood.

Substantial carbon drawdown potential from enhanced rock weathering in the United Kingdom [PDF]

, 2022
Achieving national targets for net-zero carbon emissions will require atmospheric carbon dioxide removal strategies compatible with rising agricultural production.

The circular nutrient economy of terrestrial ecosystems and the consequences for rock weathering

Frontiers in Environmental Science, 2023
Earth’s biosphere is thought to exert a substantial influence on regolith evolution and chemical weathering rates. However, ecosystems are also highly efficient at retaining and recycling nutrients.

Enhanced Rock Weathering Increases Soil Carbon but Reduces Soil Organic Carbon Stability in Subtropical Croplands

Agriculture
Enhanced rock weathering is regarded as a promising carbon dioxide removal method because of its potential to sequester soil inorganic carbon (SIC).

Incorporating enhanced rock weathering into sustainable forest management

Journal of Environmental Management
Enhanced rock weathering (ERW) can be implemented in managed forests that use selective harvesting through trail networks for carbon dioxide removal (CDR) while improving soil health by neutralizing excess acidity and restoring base cations. Wollastonite-rich rock powder (Wo = 28.4 wt% and D50 = 350 μm) was applied using a tractor and spreader from a ...
