Abstract
A nitrogen fertilizer composition includes urea and a nitrate-based fertilizer such as ammonium nitrate, calcium ammonium nitrate and mixtures of ammonium nitrate and calcium ammonium in which the urea and total nitrogen are at concentrations of 20 percent by weight or greater and the concentration of ammonium nitrate is at 30 percent or greater by weight. One or both of the urea and nitrate-based fertilizer are coated with an agriculturally compatible material. The fertilizer composition provides significant nitrate nitrogen for legitimate agricultural use yet is not amenable to the production of an explosive by crushing or by aqueous extraction. A pleasant smelling odorant is added to the composition to facilitate detection.
