Soil carbon loss since advent of farming

Proceedings of the National Academy of Sciences

A global soil model based on historical land use data estimates that agricultural land use has resulted in the loss of 133 Pg of carbon from the top 2 meters of soil over the past 12,000 years, and indicates hotspots of soil carbon loss that are often associated with major cropping or grazing regions, suggesting the existence of identifiable regions that could be targeted for soil carbon restoration.
