Abstract
An improved particulate, ammonium nitrate is prepared with 2.0-6.0 percent by weight potassium sulfate. The potassium sulfate suppresses crystalline phase IV.revreaction.III transitions in the ammonium nitrate particles while undergoing temperature variations between 18.degree.-42.degree. C. The resulting fertilizer, which may be further coated to further suppress dusting, exhibits superior resistance to caking, clumping and cracking.
