Exact excerpt

Here we show, using century-scale records of agricultural liming and anthropogenic acidity inputs for the Mississippi River Basin, that agricultural liming has acted as a net carbon sink over the past century. Records of river alkalinity fluxes suggest that approximately 90% of the ideal CO2 removal potential of agricultural lime added since 1900 (approximately 0.44 GtCO2) has been realized at the catchment scale, with a decadal-scale time lag owing to soil cation exchange and solute transport.
