Abstract

Coatings for agricultural grade fertilizer particles and industrial grade ammonium nitrate are provided which when applied to particles form a protective film which acts as a barrier to inhibit or prevent hydrocarbon infiltration of the fertilizer particle pores and also to physically separate the fertilizer particles and hydrocarbon materials. In so doing, the coating greatly reduces the efficacy of the fertilizer particles as an oxidizing agent for use in incendiary devices, thereby deterring or preventing the use of agricultural grade fertilizers or industrial grade ammonium nitrate in creating weapons of terror.
