Sustainable Use of Pelletized Broiler Litter in the Chesapeake Bay Watershed

Dr. Josh McGrath is the PI. The duration is from June 2007 – 2008. The purpose is to establish the total and plant available nutrient content and the nutrient mineralization rates of pelletized litter and to determine realistic methods of application of pelletized litter. Furthermore, to develop effective recommendations that promote environmentally and economically sustainable use of pelletized litter in commercial grain production through this study.

Field and laboratory studies will be conducted to determine optimum practices for the use of pelletized broiler litter. Increasing the acceptance of pelletized broiler litter and expanding its use is will help to increase transport of broiler litter away from regions of concentrated broiler production, a key strategy in reducing regional nutrient surpluses and thereby protecting water quality. Best management practices developed through this research will be widely disseminated through the extension activities and publications.

The current study is ongoing. Anticipated impacts are increased use of pelletized broiler litter outside of poultry producing regions and a decrease in nutrient losses to surface and groundwater from these regions.
