Description

The issue of nitrogen (N) fate and transport, particularly nitrate-nitrogen (N03-N) leaching, and the resultant contamination of surface and groundwater resources is a continuing public concern. A recent newspaper editorial (July 1, 2001) in the Des Moines Register entitled "Nitrate madness," noted that N03-N can pose human health hazards relative to methemoglobamemia, certain forms of cancer, and miscarriages, as well as cause ecological damages such as hypoxia in the Gulf of Mexico. It was also noted that in Iowa, agriculture is a major source ofN03-N loss, but that: "A variety of means are available to reduce nitrates, but they need to be universally practiced to be effective."
