Abstract
The present invention is a method of recycling animal waste into a useable soil nutrient. The method involves separating the solid and liquid fraction of an animal waste slurry and separately treating both fractions with effective amounts of activated naturally occurring soil bacteria. The method also involves adding an odor eliminating microorganism to the animal waste to reduce or eliminate the foul odor of the waste material.
