Nutrient and Poultry Litter Management
The 1997 pfiesteria outbreak in the Chesapeake Bay underscored the importance of managing farm nutrients to protect the environment. Maryland’s Water Quality Improvement Act of 1998required farmers to use manure and chemical fertilizers in accordance with approved nutrient management plans designed to reduce nutrient leaching and runoff that can harm the Bay. Research and extension faculty at the University of Maryland have analyzed the likely economic impacts of the Act and have discussed ways government can make compliance easier and less costly.
