  Document ANSI-8220 On-Farm Mortality Composting of Livestock Carcasses

By Josh Payne and Brian Pugh. Livestock mortality is an issue faced by every livestock farming operation, both large and small. For many producers, carcass disposal options are limited, can be costly, and may temporarily disturb the land needed for grazing. Improper disposal of dead animal carcasses and the resulting leach­ate (carcass fluids) can negatively impact surface water and groundwater quality. One state approved procedure that livestock producers may not be familiar with is composting. By definition, composting is a controlled biological decomposition process that converts organic matter into a stable, humus-like product. While backyard composting systems have a well-blended mixture of components (carbon and nitrogen), which results in a rapid compost cycle, livestock composting is a slower process. Composting livestock carcasses is characterized by the break down of a large centralized nitrogen source (carcass) that is surrounded by a carbon source (bulking agent). Reviewed June 2013.

  Document BAE-1750 Anaerobic Digestion of Animal Manures: Types of Digesters

By Douglas Hamilton. All anaerobic digesters perform the same basic function. They hold manure in the absence of oxygen and maintain the proper conditions for methane forming microorganisms to grow. There are a wide variety of anaerobic digesters, each performing this basic function in a subtly different way. Seven of the most common digesters are described in this document. Revised February 2014.

  Document E-1027 Poultry Litter Nutrient Management: A Guide for Producers and Applicators

By Josh Payne and Hailin Zhang. When properly managed, poultry litter provides an excellent source of plant nutrients and organic matter for application to pastureland and cropland. Continual applications also may raise the pH of acidic soils in some cases. Many variables affect the overall value and cost of litter to the end-buyer and should be carefully considered before purchasing. Due to air and water quality concerns, regulations and proper nutrient management must be followed to reduce environmental impact. Reviewed November 2014.
