Adding Limestone to Mississippi River Basin Farmlands Acts as a Major Carbon Sink, Study Finds

Farmers across the Mississippi River Basin have spread crushed limestone on their fields for generations to boost yields and reduce soil acidity. New research led by Yale scientists found that the practice also helps in the fight against climate change — liming pulls more CO2 out of the atmosphere than it releases. The finding challenges how the Intergovernmental Panel on Climate Change's default accounting treats liming as a source of CO2 emissions and points instead to its potential as a scalable climate solution.
