Abstract
The present disclosure provides desensitized fertilizer compositions that are resistant to detonation. The desensitized fertilizer compositions of the present disclosure are formed, under heat, from a reaction product of a base fertilizer material, such as ammonium nitrate, and a phosphate-based additive, such as ammonium polyphosphate. The resulting compositions include monoammonium phosphate (MAP), diammonium phosphate (DAP), and polyphosphate crystals distributed throughout the crystalline fertilizer material. The presence of the distributed MAP and DAP crystals is believed to stabilize the base fertilizer material and reduce or eliminate the detonation potential of the fertilizer material.
