Subject: [CDR] Farming with crops and rocks to address global climate, food
and soil security | Nature Plants
To: "Carbon Dioxide Removal" <carbondioxideremo...@googlegroups.com>
> “The magnitude of future climate change could be moderated by immediately
> reducing the amount of CO2 entering the atmosphere as a result of energy
> generation and by adopting strategies that actively remove CO2 from it.
> Biogeochemical improvement of soils by adding crushed, fast-reacting
> silicate rocks to croplands is one such CO2-removal strategy. This approach
> has the potential to improve crop production, increase protection from
> pests and diseases, and restore soil fertility and structure. Managed
> croplands worldwide are already equipped for frequent rock dust additions
> to soils, making rapid adoption at scale feasible, and the potential
> benefits could generate financial incentives for widespread adoption in the
> agricultural sector. However, there are still obstacles to be surmounted.
> Audited field-scale assessments of the efficacy of CO2 capture are urgently
> required together with detailed environmental monitoring. A cost-effective
> way to meet the rock requirements for CO2 removal must be found, possibly
> involving the recycling of silicate waste materials. Finally, issues of
> public perception, trust and acceptance must also be addressed.”
