Other uses for anhydrous ammonia include manufacturing and refrigeration purposes in industrial settings.


What is nitrogen fertilizer?

Anhydrous ammonia is a chemical compound that is commonly used as nitrogen fertilizer in farming applications. It is made up of one part nitrogen and three parts hydrogen (NH3). While Earth’s atmosphere is comprised of nearly 80% nitrogen, it is not in a chemically usable form nor is it biologically usable for plants. Since fertilizers are used for over 50 percent of global food production, they need to be easily attainable and safe for our food supply. Nitrogen is found in water, soil, and air and is an essential element for all living things on earth such as plants, animals, and people.


How is ammonia produced?

Ammonia is typically produced by the catalytic reaction of nitrogen and hydrogen. Nitrogen is pulled from the atmosphere using a process called the Haber-Bosch process, with a high temperature and high pressure. Through this 20th century process, nitrogen is combined with a hydrogen source and converted into a usable form. The hydrogen is gasified to form a synthesis gas (CO and H2), which will then be reacted with water and nitrogen to produce ammonia. The following equation depicts the synthesis process:


What is CuSO4 used for?

Anhydrous copper (II) sulfate (CuSO4) is used as a pesticide, an additive for fertilizer or animal feed, as well as a veterinary drug, among many other uses.


Does ammonia have water in it?

Anhydrous ammonia contains no water. However, it has a strong affinity for water, requiring large quantities to neutralize its caustic effects on the body. When it comes in contact with water, it forms an alkali that chemically burns skin tissue and continues to burn until it is diluted by large quantities of water. This skin is killed and not capable of healing or replacing itself.


Can ammonia be stored in a non-refrigerated tank?

Anhydrous ammonia can also be stored in non-refrigerated bulk storage tanks. Special care must be given to ensure these tanks are not overfilled. Overfilling means that there is insufficient vapor space above the liquid that allows for adequate thermal expansion as ambient temperatures fluctuate.


What is anhydrous ammonia?

Why is ammonia used as fertilizer?

175 million tons of anhydrous ammonia was produced in 2016 and 80% or more of it was used as fertilizer due to its high nitrogen content. To go into more depth on why the agriculture business likes to use it as fertilizer, NH 3 has a molecular weight ratio of 82.5% nitrogen to 17.5 % hydrogen which is why large-scale wheat and corn farmers use it often.


Why do farmers need to supplement soil with ammonia?

When this natural nitrogen source isn’t present, farmers must supplement the soil with ammonia to promote productivity in their crops.


What is anhydrous ammonia? Why is it so dangerous to handle?

What is anhydrous ammonia, and why is it so risky to handle? It is a chemical made up of one part nitrogen and three parts hydrogen. The properties of this fertilizer make it one of the most potentially dangerous chemicals used in agriculture. Ammonia gas is colorless and has a sharp, penetrating odor. When used as an agricultural fertilizer, it is compressed into a liquid. In the liquid state, it is stored in specially designed tanks strong enough to withstand internal pressures of at least 2 0 pounds per square inch (psi) (Figure 1). As the outside temperature increases, the temperature of the liquid in the tank increases and the liquid expands, causing the vapor pressure in the tank to increase. For example, at 60 degrees F, the pressure is 93 psi and at 100 degrees F, the pressure is nearly 200 psi (Figure 2).


What happens when ammonia is injected into soil?

When injected into the soil, the liquid ammonia expands into a gas and is readily absorbed in the soil moisture (Figure 3).


Why do you need to maintain an ammonia tank?

Regularly scheduled maintenance is necessary to ensure that the tank and other components are ready for ammonia service. As nurse and applicator tanks become older, the hazards increase. Before using ammonia equipment, perform a walk-around inspection to locate any defects. Safety checklists are available from many anhydrous ammonia suppliers. Any parts found defective must be replaced or repaired. If this is not possible, the unit must be taken out of service.


How many gallon containers of water should be in an ammonia nurse tank?

Regulations require that all anhydrous ammonia nurse tanks and applicator tanks carry at least one five-gallon container of clean water (Figure 5). This must be readily available for flushing the eyes and skin in case of exposure. The water should be changed daily to ensure a clean supply.


How does ammonia affect the body?

This damage results from a combination of dehydration, freezing, and caustic action. If a person’s skin has been exposed to ammonia, move the victim to a safe area, and flush the exposed area immediately with clean water for at least 15 minutes (Figure 15). Remove contaminated clothing as soon as possible. Do not apply salves, creams, or ointments, since these may seal residual ammonia in the skin and contribute to further damage. Contact a doctor immediately after administering emergency first aid treatment.

How does anhydrous ammonia work?

Farmers store and transport anhydrous ammonia in liquid form in pressurized tanks. Using an anhydrous applicator pulled by a tractor, the high-pressure liquid converts to a liquid-gas mixture as the pressure drops while traveling from the tank to the knife outlet on the applicator.


Why is ammonia used in fertilizer?

Anhydrous ammonia is often a preferred nitrogen source for many reasons. It is more concentrated than other forms of nitrogen, containing 82% nitrogen. It is readily available, because it is used in the manufacturing process of other nitrogen fertilizers. It can be applied long before the crop is planted.


What is the form of nitrogen that plants use for growth?

These ammonium ions can be taken in by plants and used directly in proteins. Over time, the ammonium converts to nitrate (NO 3) which is the form of nitrogen most used by plants for growth and development. Nitrate does not bond to soil like ammonium does and could leach out of the soil and into waterways.


What is the nitrogen that is used in plants?

Once in the ground, the ammonia (NH 3) ions react with moisture in the soil and convert to ammonium (NH 4 ). Ammonium ions are very stable in the soil. They carry a positive charge and are bonded to negatively charged soil particles like clay and organic matter. These ammonium ions can be taken in by plants and used directly in proteins. Over time, the ammonium converts to nitrate (NO 3) which is the form of nitrogen most used by plants for growth and development. Nitrate does not bond to soil like ammonium does and could leach out of the soil and into waterways. Nitrogen fertilizer stabilizers are often added to anhydrous ammonia before application to slow the conversion of ammonium to nitrate, thus helping to reduce nitrogen loss from leaching.


How do plants use nitrogen?

Plants use nitrogen by absorbing either nitrate (NO 3) or ammonium (NH 4) ions through their roots. Soybeans and other legume plants can convert atmospheric nitrogen into a usable form because of nitrogen fixing bacteria on their root nodules. Other plants, like corn, need to have an ample supply of available nitrogen in the soil. Farmers can add nitrogen to fields in the form of livestock manure, granular urea, liquid nitrogen (UAN solution), and anhydrous ammonia.


Why is nitrogen important for farming?

Good nitrogen management is critical for growing healthy plants, good yields, and a profitable farm business. Farmers consider crop nutrient requirements, results of soil tests, soil conditions, weather, cost, time, and equipment available before choosing a fertilizer program that is the best fit for their operation.


When to apply ammonia fertilizer?

If applied in the spring, it is best to apply it at least 3-5 days before planting to avoid damaging seeds and emerging roots.
