Lime should never be added to manure in a poorly ventilated or confined space. Biological Treatment Anaerobic Lagoons Anaerobic lagoons stabilize livestock manure by taking advantage of natural processes. In the absence of oxygen, all high-strength organic wastes, such as livestock manure, will be digested by anaerobic bacteria. Volume is reduced due to conversion of solids to methane gas and carbon dioxide. Anaerobic lagoons for livestock manures also have several limitations.
Lagoons create odors.
Ammonia nitrogen is lost. Large size is necessary. One group of bacteria converts organic wastes to organic acids. The second group converts the organic acids to methane gas and carbon dioxide. The second group of bacteria, the methane formers, is very sensitive to upset.
