Thesis (M.S.)--Hood College, 2000.

Production of large numbers of chickens (Gallus gallus domesticus ) in the Chesapeake Bay watershed has resulted in application of large quantities of poultry litter and manure to agricultural land. Poultry litter has been applied to land based on N concentration in litter and on crop requirements for nitrogen. Consequently, phosphorus has been applied (in poultry litter) at rates that exceed crop uptake. Excess nutrient applications combined with nutrient movement by erosion and leaching threaten the health of the Chesapeake Bay.

520 $a The incubation study reports N and P availability from poultry litter, in a controlled environment. The effect of source and application rate of poultry litter (composted (CPL) or fresh (FPL)), on N mineralization and availability of P in 3 soil types was determined. Fresh and composted litter from 2 sources (Dorchester County, Maryland on the Delmarva peninsula and Moorefield, West Virginia) were used. Two rates of litter application were based on nitrogen requirements of peach trees and N concentrations in litter. The soils were representative of the Delmarva peninsula and eastern WV.
