Abstract
This paper investigates the linkages between terrestrial and aquatic landscapes, with respect to nutrient transfer and environmental impacts. The nutrient sources and fluxes from terrestrial landscapes, particularly those of significance in agricultural catchments are reviewed. The effects of added nutrients on aquatic systems, focusing on impacts on rivers and methodologies used to determine river trophic status, are then examined. Finally, an advice on managing nutrient fluxes to rivers from agricultural landscapes, developing nutrient targets for rivers, and research priorities are presented.
