What is ammonium nitrate?
Ammonium nitrate can be found naturally as a mineral and it can also form when ammonia gas reacts to nitric acid by a process called nitrification. It is commonly used worldwide as fertilizers and often is stored in bulk quantities. It is a white crystalline compound or granular solid at normal temperatures.
PAST ACCIDENTS
Some of the world’s deadliest industrial accidents were caused by ammonium nitrate explosions:
USE IN BOMBINGS
Ammonium nitrate can be mixed with other substances to make a bomb. It was used in Irish Republican Army (IRA) bombings in London in the 1990s, the 1995 explosion that blew up a federal building in Oklahoma City, killing 168 people, and the 2002 blasts in Bali nightclubs in which more than 200 died.

Ammonium Nitrate
One of the most common types of ammonia is ammonium nitrate. This is an excellent source of nitrogen for your lawn and is an ingredient of many commercial fertilizers. Ammonium nitrate is used in weed and feed fertilizers that are designed to be used throughout the fall and winter.
Household Ammonia
Household ammonia is also known as Ammonium hydroxide. This compound is found in many household cleaners, such as soap or dish soap. Some people recommend using Ammonium hydroxide to create a home weed killer. While household ammonia is a powerful solution and can help eliminate weeds, you’ll also have to be careful what it comes into contact with.
Ammonium Sulfate
Ammonium sulfate is a chemical that can be used when gardening. It’s not usually added to commercial lawn fertilizers due to its acidity. This product will change the soil pH and make it more acidic. This is beneficial for plants that like acidic soils but isn’t good for your grass.
Ammonium Phosphate Sulfate
Ammonium phosphate sulfate is often used as a fertilizer for young grass seedlings. It’s beneficial as it’s much gentler than ammonium nitrate and also contains phosphate. This type of ammonia is used to treat the soil before grass seeds are planted or new sod is laid.
