Liming farmlands in the Mississippi River Basin acts as a major carbon sink, Yale study finds

A Yale-led study found that farmers in the Mississippi River Basin store more CO2 in the soil than they emit when they add limestone to their fields, a practice known as liming. The agricultural practice turns farmland into a significant carbon sink.
