Description

Nitrogen fertilizer is a major input into production costs of corn, cotton, wheat and other crops. Anhydrous ammonia is the most popular form of nitrogen application. In the United States 4.9 million tons of anhydrous ammonia were applied in both 1996 and 1997 (Terry and Kirby, 1997). Comparing fertilizer usage by source, anhydrous ammonia supplied 4.0 million pounds of nitrogen to U.S. crops while the next most popular source, nitrogen solutions, supplied just 3. 0 million pounds of nitrogen.
