High Value Organic Containing Fertilizers and Methods of Manufacture

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 a predetermined amount of nitrogen;
• agitating the liquid mixture in the second vessel for a second period of time;
• and
• discharging the liquid mixture from the second vessel to form the fertilizer with a predetermined slow release profile of nitrogen, sulfur and/or phosphorous.
