Research Areas

Research is needed to understand and develop methods to treat soils to accelerate natural weathering reactions and other processes favorable to removal of CO2 from the atmosphere.

Research is needed in the following areas:

  • To assess the weathering rates of suitable alkaline minerals in soils. Such research should enable crude prediction of how weathering rates depend on the size and pretreatment of the base rock, on the kind of soil, and on the means of application of the alkaline minerals.

  • To increase understanding of the fate of metal ions leached into soils.

  • To assess the impacts of adding small amounts of base to soils.
