Quantification of CO2 Uptake by Enhanced Weathering of Silicate Minerals Applied to Acidic Soils [PDF]
International Journal of Greenhouse Gas Control, 2023 The application of ground silicate minerals to agricultural soils has been proposed as a method for taking up CO2 by enhancing the weathering rate of these minerals through their exposure to soil acids. Alternatively, glacial rock flour, a finely grained material which is abundantly available without the need for energy-intensive grinding, could be ...

Frontiers in Climate, 2023 Enhanced weathering is a negative emission technology that involves the spread of crushed silicate minerals and rocks on land and water. When applied to agricultural soils, the resulting increase in soil pH and release of nutrients may co-benefit plant productivity.

Risk Assessment of Ni, Cr, and Si Release From Alkaline Minerals During Enhanced Weathering [PDF]
Open Agriculture, 2020 Abstract Calcium- and magnesium-rich alkaline silicate minerals, when applied to soil, can aid in carbon dioxide sequestration via enhanced weathering. The weathering of these silicate minerals is also associated with the release of heavy metals such as Ni and Cr, depending on the composition of the parent rock, and also labile Si.

Are Enhanced Rock Weathering Rates Overestimated? A Few Geochemical and Mineralogical Pitfalls
Frontiers in ClimateThere is considerable uncertainty when quantifying carbon dioxide removal (CDR) from enhanced rock weathering (ERW). Faster CDR rates mean ERW may significantly impact climate change mitigation, and more carbon credits will financially benefit private ...

Use of Mineral Weathering Bacteria to Enhance Nutrient Availability in Crops: A Review [PDF]
Frontiers in Plant Science, 2020 Rock powders are low-cost potential sources of most of the nutrients required by higher plants for growth and development. However, slow dissolution rates of minerals represent an obstacle to the widespread use of rock powders in agriculture. Rhizosphere processes and biological weathering may further enhance mineral dissolution since the interaction ...
