    Dry Poultry Litter Incorporation Into No Till Soils to Minimize Trace Elements and Nutrient Movement to the Chesapeake Bay

    NON-TECHNICAL SUMMARY: Land application of manure is one of the most sensitive and important water quality issues facing livestock farmers in the Chesapeake Bay watershed today. Research has revealed that the repeated application of manure to soil can enrich nitrogen (N) in groundwater and phosphorus (P) in surface runoff.  In the coastal plain soils of Maryland's Eastern Shore, leaching of P is also a significant source of P in ground and surface waters. Eutrophication of the Chesapeake Bay estuary is tied, in part, to all of these processes. This project will test the sub surface injection of manure, which has been identified as a key to combating the accumulation of water soluble nutrients and harmful trace elements at the surface of no till soils. In addition to minimizing dissolved nutrient runoff, this project will exam the effect of manure injection on ammonia volatilization reduction, reduced odor emissions, and improve crop yields by placing manure nutrients in the rooting zone.
