Anhydrous ammonia is a colourless gas made of one nitrogen atom bonded with three hydrogen atoms (NH3). It has a strong, suffocating odour and can be fatal if inhaled in large concentrations. Anhydrous ammonia is not flammable, but it can burn in the presence of oxygen when it is extremely pressured or heated. It is also corrosive and can cause chemical burns and damage the eyes.

Ammonia is used in many industrial and agricultural processes and is one of the most widely produced chemical compounds in the world. In industry, it is employed in manufacturing fertilizers, explosives, textiles, dyes and pharmaceuticals. It is also used as an industrial cleaning agent and as a refrigerant in certain refrigeration systems.

In agriculture, anhydrous ammonia is primarily used as a nitrogen-based fertilizer, providing nitrogen for plant growth. It can be applied to crops in both pre-plant and sidedress applications. It can also be injected directly into the soil.

Anhydrous ammonia is widely transported and stored in large quantities, due to its economic importance. However, because it is a hazardous substance, strict regulations and safety precautions must be followed in handling and storage processes to avoid potential risks and accidents.
