    A geochemical investigation into the occurrence and fate of nitrogen and phosphorus in the lower Oliphants River, Western Cape
    (2004) Germs, Wijnand J; Compton, John; Roychoudhury, Alakendra
    Knowledge of nutrient dynamics within aquatic ecosystems are of fundamental importance for water quality management, especially in cultivated areas where irrigation farming pose a salinization and eutrophication risk to water bodies. A range of water quality problems is associated with eutrophication, which is generally controlled by the nutrients nitrogen and phosphorus. The lower Olifants River is situated in an arid region with intensive irrigation agriculture. This study set out to investigate the loading and fate of nitrogen and phosphorus in the lower Olifants River.
