Abstract
A method to prevent the removal or deactivation of the calcium carbonate diluent from calcium ammonium nitrate (CAN) fertilizer by terrorists or insurgents attempting to produce home-made-explosives, such as ANFO. A first embodiment involving dry mixing an organic polymer and CAN fertilizer—such that if the mixture is added to water a hydrogel will be formed defeat the separation of the calcium carbonate. A second embodiment involving adding encapsulated water or encapsulated urea, such that if the mixture is ground to a fine powder to defeat the effect of the diluent—the released urea will take water out of the atmosphere or the released water (from the encapsulated water) will interact with the organic polymer to create a hydrogel, to maintain the non-detonability of the CAN.
