Short summary
The role that hydrology plays in controlling the interplay between dissolved organic carbon (DOC) and nitrogen in rivers of lowland, agricultural landscapes is poorly understood, yet important to assess given the potential changes to production and delivery of DOC and nitrate arising from climate change. We measured DOC and nitrate concentrations in river water of the lowland river Hampshire Avon (Wiltshire, southern UK), revealing significant seasonal variations in DOC : nitrate transport.
