Slapton Ley, a coastal lake in SW England, has been shown by a variety of paleolimnological studies, to have become increasingly eutrophic in the period since AD. Since that time, intensification of agriculture has resulted in increased erosion of topsoil from fields in the catchment of the :// Sequential inorganic chemical analysis of a core from Slapton Ley, Devon, UK.
