Author(s) Larry G. Bundy, Lynda Knobeloch, Bruce Webendorfer, Gary W. Jackson, Bryon H. Shaw.

Although nitrogen can cause environmental and health problems, it is an essential element in living matter. Nitrogen is a major component of proteins and DNA, and is indispensable in the production of food and fiber. This publication explains how this complex and dynamic element works in the environment, its role in agriculture, the numerous nitrate sources that can contaminate groundwater, its impact on human and animal health, and what can be done to keep nitrate from building up to potentially harmful levels in groundwater (8 pages; Revised in 1994).
