Abstract

Soil amendments and fertilizers may include potentially toxic elements
that may be accumulated by plants. The elemental composition
of municipal sludges has been studied in great detail (Furr
et al. 1976; Mumma et al. 1984). Fish hatcheries in south-central
Idaho have been ordered by the U.S. Environmental
Protection Agency to discontinue sweeping accumulated wastes downstream
into the Snake River. Alternatives include landfilling and
domestic use of the manures as lawn fertilizer. It has been proposed
(Smith, 1982, 1985) that fish manures are suitable fertilizers
for crops such as corn and sugar beets.

Sewage sludges and manures have increasingly been disposed of as
soil conditioners and low grade fertilizers. In 1981 the U.S.
Environmental Protection Agency proposed upper limits of certain
heavy metals for sewage sludges suitable for land application. The
following upper limits (ppm) were proposed: cadmium (25), chromium
(1000), copper (1000), lead (1000), mercury (10), nickel
(200), and zinc (2500). We determined the concentrations of these
elements, plus arsenic and cobalt, in fish manures being evaluated
as fertilizers for Idaho croplands. We also determined nitrogen,
phosphorus, and potassium in fresh fish manures.
