Loss of deep roots limits biogenic agents of soil development that are only partially restored by decades of forest regeneration

Loss of deep roots limits biogenic agents of soil development that are only partially restored by decades of forest regeneration

Roots and associated microbes generate acid-forming CO2 and organic acids and accelerate mineral weathering deep within Earth’s critical zone (CZ). At the Calhoun CZ Observatory in the USA’s Southern Piedmont, we tested the hypothesis that deforestation-induced deep root losses reduce root- and micr...
