AB - We couple meteoric <sup>10</sup>Be measurements with mass balance analysis of <sup>9</sup>Be to estimate the soil residence time (SRT) of a biogeomorphically stable Ultisol in the Southern Piedmont physiographic region of the southeastern United States. We estimate SRT after correcting the meteoric <sup>10</sup>Be inventory to account for observed <sup>9</sup>Be losses, which indicate that more than half of the <sup>9</sup>Be weathered from primary minerals has been leached from the upper 18.3 m of the Ultisol. Our estimates of minimum SRT range between 1.3-1.4 Ma and between 2.6-3.1 Ma under high and low (2.0 and 1.3 × 106 atoms cm <sup>-2</sup> yr <sup>-1</sup>, respectively), estimates of <sup>10</sup>Be delivery. Denudation rates of the physiographic region corroborate our estimates. We redefine pedogenic time constraints in the Southern Piedmont, and demonstrate that the assumption of complete meteoric <sup>10</sup>Be retention in acidic soil systems cannot always be made; the latter has far-reaching consequences for soil, sediment, river, and ocean research using meteoric <sup>10</sup>Be. © 2012 Geological Society of America.
