Problems found at Minn. anhydrous ammonia plantsWhile ammonium nitrate is not commonly used on Minnesota farms, anhydrous ammonia is. It’s a colorless gas that’s stored under pressure in liquid form. It’s pumped into the soil as a source of nitrogen. The state has 287 anhydrous ammonia storage facilities, and they’re regulated and inspected by the Minnesota Department of Agriculture.
