PFR Report: ANHYDROUS AMMONIA

Author: Chris Grimm

Nitrogen is one of the 16 essential elements required for plant growth. The most common nitrogen fertilizer forms include anhydrous ammonia (NH3), urea, and urea-ammonium nitrate (UAN) solutions. Anhydrous contains 82% nitrogen, the highest amount of any nitrogen fertilizer. Once applied in the soil, anhydrous ammonia converts to the ammonium form (NH4+). Ammonium ions are very stable in the soil. Over time, ammonium converts to nitrate (NO3), which is the form of nitrogen most used by plants.
