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&#x2014;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&#x2014;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.
