Environmental
Litter spreading on lands for fertilizer value: If not managed, it has been attributed to buildup of nutrients, especially high phosphorus levels in soils and may cause surface and groundwater contamination

Broiler Litter Analysis
Very low in cellulosic content Brinson farms has maintained bedding that is free of wood shavings and other added materials for 5 years Contains unconsumed chicken feed Lab tests show good biogas potential (presented by Mississippi State University at American Institute of Chemical Engineers – AIChE meeting in November, 2004) Litter is primarily manure and feed
