High value organic containing fertilizers and methods of manufacture
First Claim
1. A method for manufacture of a fertilizer with a predetermined nutrient release profile comprising:
- conditioning an amount of an organic material to a predetermined degree of wetness, wherein the type and/or amount of organic material establishes the slow release nutrient profile of the fertilizer;
adding an odor control agent to the conditioned organic material to form a mixture;
transferring the mixture to a first vessel to which is added a concentrated acid creating an exothermic reaction, wherein the amount of acid added creates a predetermined temperature forming a liquid mixture;
agitating the acidified mixture for a first period of time;
transferring the liquid mixture under pressure to a second vessel to which is added an amount of anhydrous ammonium sufficient to further increase the temperature and pressure of the liquid mixture such that the liquid mixture contains ammonium ions and a predetermined amount of nitrogen;
agitating the liquid mixture in the second vessel for a second period of time wherein the ammonium ions non-covalently bind to organic and other chemical compounds of the fertilizer; and
discharging the liquid mixture from the second vessel to form the fertilizer with a predetermined slow release profile, wherein the predetermined slow release profile is a profile of one or more of nitrogen, phosphorous, potassium, sulfur, iron, organics and combinations thereof.

Abstract
The invention is directed to manufacturing fertilizers having commercial levels of nitrogen reacted with organic substances. The process comprises treatment of organics with acid that acidifies and heats a mix causing the hydrolysis of polymers. The acidified organic mix is injected sequentially with a nitrogen base under conditions that result in a partially neutralized melt. The sterilized and liquefied organic matter is disbursed over recycled material for production of granules in a granulator before final drying. The process is green scalable, and safe for the location of community organics processing facilities in locations without generating a nuisance to local communities. Fertilizers also provide a green, dual nitrogen-release profile when applied to crops releasing a bolus of nitrogen over one to two weeks following application followed by a continued slow or enhanced efficiency release of nitrogen over a growing season.
