They are all artistically enhanced with visually stunning color, shadow and lighting effects. It is the slowest of the four degradation steps. The lack of oxygen and abundance of organic matter in liquid manure provide the proper conditions for anaerobic bacteria to survive. Anaerobic digestion is a process through which bacteria break down organic matter—such as manure—without oxygen. Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen.
