A routine farm practice in the Mississippi River Basin may be quietly locking away carbon

Agricultural Liming Is a Carbon Sink: Yale's 120-Year Finding

For most of the industrial era, spreading crushed limestone across farmland has been treated as a carbon problem. The rock contains carbon; it ends up in contact with air and water, and by the most conservative accounting conventions, carbon is assumed to escape as carbon dioxide. Regulators and major climate assessments have baked that assumption […]
