What is anhydrous ammonia and why is it used in agriculture?

Anhydrous ammonia is a chemical compound that consists of nitrogen and hydrogen atoms, with the formula NH3. The word “anhydrous” means “without water”, which indicates that this substance has no water molecules in its structure. Anhydrous ammonia is a colorless gas with a strong and pungent odor, and it can also exist as a liquid under high pressure or low temperature.

Chemical properties and uses of anhydrous ammonia

Anhydrous ammonia has several chemical properties that make it useful for various industrial and agricultural purposes. Some of these properties are:

• It is highly soluble in water, forming ammonium hydroxide, which is a weak base that can neutralize acids.
• It can react with metals, such as copper, zinc, and iron, to form metal amides, which are compounds that contain nitrogen atoms bonded to metal atoms.
• It can act as a reducing agent, which means that it can donate electrons to other substances and reduce their oxidation state.
• It can form complexes with transition metals, such as cobalt, nickel, and platinum, which are compounds that have a central metal atom surrounded by other atoms or molecules.

Some of the uses of anhydrous ammonia are:

• It is used as a fertilizer to provide nitrogen to plants, which is essential for their growth and development. Anhydrous ammonia is one of the most efficient and economical sources of nitrogen for crops, especially corn.
• It is used as a refrigerant to cool and freeze food products, such as meat, dairy, and beverages. Anhydrous ammonia has a low boiling point and a high heat capacity, which means that it can absorb a lot of heat from its surroundings and change from liquid to gas easily.
• It is used as a precursor to synthesize other chemicals, such as nitric acid, acrylonitrile, urea, and explosives. Anhydrous ammonia can react with oxygen, hydrogen, carbon, or nitrogen to form various compounds with different properties and applications.

Benefits and drawbacks of using anhydrous ammonia compared to other nitrogen sources

Anhydrous ammonia has some advantages and disadvantages compared to other nitrogen sources for fertilizing soil. Some of these are:

• Anhydrous ammonia has a high nitrogen content (82%) and a low cost per unit of nitrogen, which makes it more affordable and effective than other nitrogen fertilizers.
• Anhydrous ammonia can be applied directly to the soil using injection systems that place it six to eight inches below the surface. This reduces the loss of nitrogen due to volatilization or leaching.
• Anhydrous ammonia can improve the soil quality by increasing its pH and organic matter content. This can enhance the availability of nutrients and water for plants.
• Anhydrous ammonia can pose health and environmental risks if not handled properly. Exposure to anhydrous ammonia can cause severe burns, irritation, or damage to the eyes, skin, respiratory system, and internal organs.
• Anhydrous ammonia requires special equipment and training for storage and application. It must be kept as a liquid under high pressure or low temperature, and it must be injected into the soil carefully to avoid contact with air or moisture.
• Anhydrous ammonia can harm plants, animals, and water sources if it leaks or spills. Anhydrous ammonia can damage plant tissues by dehydrating them or altering their metabolism. It can also harm aquatic life by reducing the oxygen levels in water or changing its pH.
