Abstract
Controlling the odor of an animal waste slurry and increasing the plant nutrient values in said animal waste slurry is achieved by contacting an animal waste slurry with about 5 ppm to about 500 ppm hydrogen peroxide, adjusting the pH of the slurry to between about 4.0 and about 8.0 with a mineral acid, mixing the slurry until the odor is no longer objectionable, and recovering the animal waste slurry which contains increased amounts of ammonium salt values.
