Anhydrous ammonia (NH3) is an efficient and widely used source of nitrogen fertilizer. It is relatively easy to apply and is readily available to producers.

However, if not handled properly NH3 can be dangerous. Anhydrous means “without water”. Because NH3 contains little or no water it aggressively seeks out moisture, be it from soil or your eyes, throat, lungs or skin. Any anhydrous ammonia contact with our bodies could cause tissue dehydration, caustic burns as well as frostbite.

When used as an agricultural fertilizer, NH3 is compressed into a liquid. This requires a substantial amount of pressure and specially designed tanks and equipment. If not stored or transported properly serious injuries are possible.

The Minnesota Department of Agriculture has important safety measures to increase the protection for agricultural workers and for people who live, work, or otherwise are near NH3. The measures include how NH3 must be stored, transported, handled, and applied. View the tabs above to learn more about the safety and regulatory programs designed to ensure safe use of NH3.

We’ve created a video to help explain how to test the pressure actuated bypass system.  This helps determine the safety and efficiency of the pump transfer system. This system must be inspected and tested at least once a year.
