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]
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.
North America's regulations for handling ammonium nitrate, a potentially explosive product used in fertilizer and in the mining industry, are the strictest in the world, the chief executive ...
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]

Lead was also mined in North Carolina. The silver had to be separated from the lead ores, which was an expensive process. The Nitre and mining Bureau took over the Silver Hill, North Carolina mines production. "In the opening stages of the war, geologists and government agents underscored the value and scope of Silver Hill's lead deposits ...
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]
An MP has described the decision to dump 300 tonnes of fertiliser into the North Sea as "an act of environmental terrorism". The ammonium nitrate had been on board the MV Ruby, which had docked in ...
