Adding lime to agricultural soils can remove CO2 from the atmosphere, rather than cause CO2 emissions, claims new research.



Summary

New research suggests applying lime (calcium carbonate) to agricultural soils can act as a carbon sink, contrary to previous assumptions. The process involves lime reacting with atmospheric CO2 to form stable carbonates in the soil, effectively sequestering the greenhouse gas. This contradicts the common understanding that lime application leads to CO2 emissions. This finding presents a potential strategy for carbon capture and storage in agricultural land, offering a nature-based solution to mitigate climate change. Further research is needed to fully quantify the carbon sequestration potential and optimize lime application methods for maximum impact.
