Soil carbon sequestration and turnover in a pine forest after six years of atmospheric CO₂ enrichment

During the first six years of atmospheric CO2 enrichment at the Duke Forest free‐air CO2 enrichment (FACE) experiment, an additional sink of 52 ± 16 g C·m−2·yr−1 accumulated in the forest floor (O‐horizon) of the elevated CO2 treatment relative to the ambient CO2 control in an aggrading loblolly pin...
