How to Apply Ammonium Nitrate as Fertilizer
Jul 21, · One of the first solid nitrogen sources produced in a large scale capacity is ammonium nitrate. Ammonium nitrate fertilizer is the most common use of the compound, but it also has a very volatile nature, which makes it useful in certain industries. Ammonium nitrate is an odorless, nearly colorless crystal salt. Jan 30, · Ammonium nitrate fertilizer is an industrially-produced chemical fertilizer. It has the chemical formula NH 4 NO 3 and is used primarily to increase the nitrogen content of soil. This type of fertilizer is typically sold in a granular form, although other preparations and combinations are possible.
Ammonium nitrateNH 4 NO 3a salt of efrtilizer and nitric acidused widely in fertilizers and explosives. The commercial grade contains nitratte Ammonium nitrate also is employed to modify the detonation rate of other explosives, such as nitroglycerin in the so-called ammonia dynamitesor as an oxidizing agent in the ammonals, which are mixtures of ammonium nitrate and powdered aluminum.
Ammonium nitrate is a colourless crystalline substance melting point It is highly soluble in water; heating of ammonium water solution decomposes the salt to nitrous oxide laughing gas.
Because solid ammonium nitrate can undergo explosive decomposition when heated in a confined space, government regulations have been imposed on its shipment and storage. Ammonium nitrate.

Aug 06, · An investigation found improper storage of the chemicals was to blame. In agriculture, ammonium nitrate fertilizer is applied in granule form and quickly dissolves under moisture. Ammonium nitrate, (NH 4 NO 3), a salt of ammonia and nitric acid, used widely in fertilizers and explosives. The commercial grade contains about percent nitrogen, all of which is in forms utilizable by plants; it is the most common nitrogenous component of artificial fertilizers. Aug 06, · Ammonium nitrate is a chemical compound widely used in farming as fertilizer. It is normally spread as small pellets and dissolves quickly in moisture, releasing nitrogen into the soil. How.
AFP Staff. Ammonium nitrate, which Lebanese authorities have said caused the devastating Beirut blast, is an odorless crystalline substance commonly used as a fertilizer and has caused numerous industrial explosions over the decades. These notably include one at a Texas fertilizer plant in that killed 15 and was ruled deliberate, and a North Korean railway blast that left dead in When combined with fuel oils, ammonium nitrate creates a potent explosive widely used in the construction industry, but also by insurgent groups such as the Taliban for improvised explosives.
Two tonnes of it were used to create the bomb in the Oklahoma City attack that destroyed a federal building, leaving people dead. Lebanese Prime Minister Hassan Diab said 2, metric tons of ammonium nitrate that had been stored for years in a Beirut portside warehouse had exploded, killing dozens of people and causing widespread damage to the capital.
In agriculture, ammonium nitrate fertilizer is applied in granule form and quickly dissolves under moisture, allowing nitrogen -- which is key to plant growth -- to be released into the soil.
However, under normal storage conditions and without very high heat, it is difficult to ignite ammonium nitrate, Jimmie Oxley, a chemistry professor at the University of Rhode Island, told AFP. That is because ammonium nitrate is an oxidizer -- it intensifies combustion and allows other substances to ignite more readily, but is not itself very combustible.
For these reasons, there are generally very strict rules about where it can be stored: for example, it must be kept away from fuels and sources of heat. In fact, many countries in the European Union require that calcium carbonate to be added to ammonium nitrate to create calcium ammonium nitrate, which is safer.
In the United States, regulations were tightened significantly after the Oklahoma City attack. Under the Chemical Facility Anti-Terrorism Standards, for example, facilities that store more than 2, pounds kilograms of ammonium nitrate are subject to inspections. Despite its dangers, Oxley said legitimate uses of ammonium nitrate in agriculture and construction have made it indispensable. Ammonium nitrate was one of the compounds that ignited in a North Korea train explosion in that killed Beirut residents vent fury at leaders, blaming them for deadly explosion.
