The invention describes a new method for the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal biosolids or organic sludges that can compete with traditional fertilizers such as ammonium phosphate, ammonium sulfate and urea on the commodity fertilizer marketplace. The method creates a thixotropic paste-like material from the biosolids or organic sludge that is blended with hot or molten ammonium salts, especially a mixture of ammonium phosphate and ammonium sulfate. The invention can be an add-on to commercial production of ammonium salts or it can stand alone by manufacturing ammonium salts prior to their introduction to the conditioned biosolids. The invention is oriented to be tailored to production facilities for individual municipal waste treatment plants in order to keep manufacturing plants small with a minimization of logistics and liability.
