Ammonia is a colorless gas with a pungent odor, composed of nitrogen and hydrogen. It is highly soluble in water and serves as one of the most important industrial chemicals worldwide. Ammonia is widely used in the production of fertilizers, explosives, plastics, textiles, and as a refrigerant in industrial cooling systems.

In agriculture, ammonia is a key ingredient in nitrogen-based fertilizers, supporting crop growth and food production. In industrial applications, it is used for water treatment, chemical manufacturing, and as an energy carrier in emerging clean energy solutions.
