An analysis of ground water and stream pollution 30 years after an agricultural study of nitrate began suggests that nitrate fertilizer can influence the watershed for decades.
Nitrate pollution from agricultural fertilizers can make water unsafe to drink, and may be causing a "dead zone" near the outlet of the Mississippi River in the Gulf of Mexico. For these reasons, farmers are being encouraged to alter their practices to use nitrogen more efficiently, but environmental improvements from these new practices have been difficult to document using short, two-to-four-year experiments. Some new findings are showing why.
An agricultural experiment concluded nearly 30 years ago is still influencing concentrations of nitrate in ground water and stream flow draining from a 74-acre field in western Iowa, according to scientists at the National Soil Tilth Laboratory, Ames, Iowa.
