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.
Ammonium nitrate-fuel oil mixture containing only prilled ammonium nitrate and fuel oil: No: NA 0337: ... Other regulated substances, liquid, n.o.s. [a] NA 3178: 4.1:
Since 3 March 2016 the possession and use of such chemicals has been regulated. [4] It references the Poisons Act 1972 and the Control of Poisons and Explosives Precursors Regulations 2015. [1] Currently in the UK the following substances are regulated as explosives precursors. [5] Ammonium nitrate. Hexamine. Hydrochloric acid. Hydrogen ...
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 ]
Examples of common binary explosives include Oxyliquit (liquid oxygen/combustible powder), ANFO (ammonium nitrate/fuel oil), Kinestik (ammonium nitrate/nitromethane), Tannerite and ammonal (ammonium nitrate/aluminum), and FIXOR (nitroethane/physical sensitizer).
The oxidizer is a mixture of 85% 200-mesh ammonium nitrate and 15% ... combining the components to constitute an explosive is typically regulated by laws on ...
Ammonium nitrate fertilizers: uniform non-segregating mixtures of nitrogen/phosphate or nitrogen/potash types or complete fertilizers of nitrogen/phosphate/potash type, with not more than 70 percent ammonium nitrate and not more than 0.4 percent total combustible/organic material calculated as carbon or with not more than 45 percent ammonium ...
Consequently, ammonium (NH 4 +) binds tightly to the soil, but nitrate ions (NO 3 −) do not. Because nitrate is more mobile, it leaches into groundwater supplies through agricultural runoff. Nitrates in groundwater can affect surface water concentrations through direct groundwater-surface water interactions (e.g., gaining stream reaches ...
