Management Practices on Phosphorus, Copper, Zinc, Manganese, and
Arsenic Concentrations in Maryland Coastal Plain Soils - The
objective of this research was to assess the long-term effects
of broiler litter applications on soil phosphorus (P), copper
(Cu), zinc (Zn), manganese (Mn), and arsenic (As) concentrations
in Chesapeake Bay watershed Coastal Plain soils. Litter and soil
samples were collected from 10 farms with more than 40 years of
broiler production and from wooded sites adjacent to fields and
were analyzed for P and metal contents. Averaged over farms,
total P and metal concentrations in the litter were 12.8 g kg-1
P and 332, 350, 334, and 2.93 mg kg-1 Cu, Zn, Mn, and As,
respectively. Surface (0-15 cm) soil pH values were greater than
(5.7-6.4) the 0- to 15-cm depth at wooded sites (3.5-4.3).
Surface soil Bray 1 P values (149-796 mg kg-1) in amended fields
were greater than
