Images from Beirut reveal a distinct reddish colour to the plume of gases from the blast. Ammonium nitrate is predominantly used in agriculture as a high-nitrogen fertiliser. This major plant nutrient can be taken in by plants through the roots or from the stoma in the leaves and stems. The commercial grade contains about 33.5 percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers. While we don’t know for sure what caused the explosion in Beirut, footage of the incident indicates it may have been set off by a fire – visible in a section of the city’s port area before the explosion happened. Ammonium nitrate has the chemical formula NH₄NO₃. — This will almost certainly have contributed to the tragic circumstances that resulted in a commonplace industrial fire causing such a devastating explosion. Ammonium nitrate is predominantly used in agriculture as a fertiliser. The most common uses for the fertilizer are in vegetable gardens and in hay and pasture fertilization due to the high nitrogen content. Nitrogen comes in many forms. Ammonium nitrate does not burn on its own. Read more: Ammonium nitrate decomposition can be set off if an explosion occurs where it’s stored, if there is an intense fire nearby. In most cases, the compound is very stable and can only become explosive in certain conditions. Find more gardening information on Gardening Know How: Keep up to date with all that's happening in and around the garden. Unfortunately ammonium nitrate is also used to create homemade explosives, often used by terrorists, called a fertilizer bomb. Ammonium nitrate is the fertilizer compound that can be used in explosives, said John Goodpaster, who researches explosives at Indiana at University-Purdue University Indianapolis. Ammonium nitrate, a salt of ammonia and nitric acid, used widely in fertilizers and explosives. For an industrial ammonium nitrate disaster to occur, a lot needs to go wrong. It’s relatively difficult for a fire to trigger an ammonium nitrate explosion. Ammonium nitrate is predominantly used in agriculture as a fertiliser. Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us. Calcium ammonium nitrate is an inorganic compound that is widely used as a fertilizer. — m.) of land. It's also used to create controlled explosions in mining and quarrying. Ammonium nitrate is an industrial chemical commonly used around the world as an agricultural fertilizer, and in explosives for mining. Easier forms of nitrogen that occur in processed fertilizers include ammonium nitrate. The Conversation UK receives funding from these organisations. A giant mushroom cloud rose above the city following the explosion on Tuesday. With this method, you drill into the end of a mining chamber called a stope, which is a bit like a tunnel with a brow coming down from the back (what we’d call the ceiling). Ammonium nitrate is a chemical compound used in agriculture as a fertilizer, to make pyrotechnics, as an ingredient in cold packs, and for science demonstrations. Using ammonium nitrate in gardens and large scale agricultural fields enhances plant growth and provides a ready supply of nitrogen from which plants can draw. By Finlay Greig.
