Ammonium nitrate is one of the
two leading nitrogen fertilizer materials on a world basis:
10% in 1997. The high N content is advantageous for the
reduction of freight and application costs per unit weight
of nitrogen. The presence of 50% of the nitrogen in the
highly available nitrate form makes it suitable for use
in regions growing crops with a short vegetation period
but has the disadvantage that, because the NO3
? ion is
not adsorbed by soil, it may contribute to relatively large
nitrogen losses by the leaching of increased soil nitrate
into streams and groundwater. Although the application
of any nitrogenous fertilizer results in some degree of soil
acidification, the nitrate form is notably less acidifying
than ammonium sulfate and has a lower tendency for the
loss of nitrogen to the atmosphere as gaseous ammonia.
The hygroscopic character of the crystalline material,
coupled with its explosive nature, contributes to difficult
storage and handling properties and the need for the
production of purified and stabilized forms.
