A number of assessments of eutrophication in the United States, particularly in coastal waters, have completed in recent years. These address the role of agricultural sources of nutrients and the potential for controlling these sources.  

National Research Council report Clean Coastal Waters: Understanding and Reducing the Effects of Nutrient Pollution See in particular Chapter 9, Source Reduction and Control.   

The Council for Agricultural Science and Technology report Hypoxia in the Gulf of Mexico: Land and Sea Interactions.

The National Science and Technology Council's Integrated Assessment of Hypoxia in the Northern Gulf of MexicoSix background technical chapters and extensive public comments are available on the Hypoxia Assessment website. See in particular the Topic 5 report, which addresses reducing nutrient loading.
