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 microbially-mediated weathering agents well below maximum root density (to 5 m), and impart land-use legacies even after ~70 y of forest regeneration. In …
Carbon and Oxygen Isotope Composition in Soil Carbon Dioxide and Free Oxygen within Deep Ultisols at the Calhoun CZO, South Carolina, USA
In order to evaluate effects of three land uses on isotopic compositions of CO 2 and O 2 of soil air to 5 m soil depth, a field study was conducted in the Calhoun Critical Zone Observatory, located in the subtropical climate of the Southern Piedmont of South Carolina, USA. Soil gas reservoirs were installed in ecosystems with three different land uses, each replicated three times: (i) reference hardwood stands that were never cultivated; (ii) cur…
