Abstract

Application of agricultural chemicals has come under increased scrutiny from environmental groups and federal regulatory agencies. Nitrogen fertilizer is used in greater quantities than any other agricultural chemical. It also is the contaminant most often found in Nebraska groundwater. Accurate application of nitrogen is important from an environmental and economic viewpoint. Approximately 800 million pounds of nitrogen are applied to 12 million acres of Nebraska cropland each year. Nitrogen applied as anhydrous ammonia (NH₃) accounts for around 40 percent of the total nitrogen applied.
