It is highly soluble in water; heating of the water solution decomposes the salt to nitrous oxide (laughing gas). Additionally, a matrix is needed to act as a heat conveyor in the presence of sufficient heat. Ammonium nitrate decomposition can be set off if an explosion occurs where it's stored, if there is an intense fire nearby.
