Anhydrous ammonia is an efficient and widely used source of nitrogen fertilizer. Anhydrous ammonia has several advantages, including its relatively easy application and ready availability.

Besides being a common source of nitrogen fertilizer, anhydrous ammonia has other purposes on the farm. It has been used with high moisture grains to control mold growth. When using anhydrous ammonia with grain, use the same precautions as you would when applying it as fertilizer. The same hazards exist whenever you handle ammonia under pressure.

Anhydrous ammonia is also used to add nonprotein nitrogen to corn silage. The ammonia is contained under pressure up to a cooling reactor in this application. Goggles, rubber gloves, and heavy-duty clothing, including long-sleeved shirts, must be worn during the process of connecting and disconnecting the ammonia hose and fitting.
