Abstract

A method of treating organic farm materials such as hays, grains, and silages confines same to a predetermined enclosure. A solid chemical mixture is introduced into the enclosure. The solid chemical mixture is a urea reactor product including ammonium carbamate, ammonia, urea, and water. Heat is applied to the mixture to thereby release sufficient gaseous ammonia to the organic farm material to prevent spoilage, reduce toxin levels, and improve fermentation of the organic farm material. The solid chemical mixture disposed amidst the organic farm material can be provided in a corrosion resistant drum having holes through the top thereof and having an electric resistance heater disposed in the bottom thereof or underneath same. A thermostatic control can control the temperature generated by the heater. The drum with the solid mixture is disposed in the midst of bales of organic farm material which has been covered by plastic sheeting weighted at the edges with mounded dirt to render the enclosure substantially gas-tight.
