<jats:p>The stability of global soil carbon (C) represents a major uncertainty in forecasting future climate change. In the UK, substantial soil C losses have been reported, while at the same time dissolved organic carbon (DOC) concentrations in upland waters have increased, suggesting that soil C stocks may be destabilising in response to climate change. To investigate the link between soil carbon and DOC at a range of sites, soil organic matter, soilwater and streamwater DOC were analysed for radiocarbon (<jats:sup>14</jats:sup>C). DOC exported from C‐rich landscapes appears younger than the soil C itself, much of it comprising C assimilated post‐1950s.
