Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [2] The use of ANFO originated in the 1950s. [3]
Prilled is a term used in mining and manufacturing to refer to a product that has been pelletized. ANFO explosive typically comprises ammonium nitrate prills mixed with #2 fuel oil . [ 2 ] The pellets are a neater, simpler form for handling, with reduced dust.
The Bureau of Land Management has banned the use of all exploding targets on BLM land in Utah. [8] In New York State, a 2020 law included binary explosives, including Tannerite, in the definition of "explosives" that require a permit for their purchase, ownership, possession, transportation, or use within the state.

In response to changes in mining technology, the product line expanded to include blasting agents based on ammonium nitrate and nitric acid in the 1940s. [7] Ammonium nitrate was produced from anhydrous ammonia and air (the DuPont process) beginning in the 1950s. [7] The original nitroglycerine-based products were phased out by 1983. [2]
The effectiveness of the water gels is dependent on the dissemination of salts in the salt solution. The particles need to be very small and fine so that they can be dispersed well throughout the solution. Some salts that are commonly used include: ammonium nitrate, sodium nitrate, sodium perchlorate and potassium chlorate.
In many traditional farming practices, fields are rotated through various types of crops, which usually include one consisting mainly or entirely of clover. [citation needed] Fixation efficiency in soil is dependent on many factors, including the legume and air and soil conditions. For example, nitrogen fixation by red clover can range from 50 ...
Ammonium compounds are used not only for fertilisers, but also explosives. Billingham-on-Tees was a small village in 1917, when its Grange Farm was chosen to be the site of a large chemical works. On 22 March 1918, the Minister of Munitions approved the site to be developed as a factory that would make ammonium nitrate. [1]
