The disposal of dead birds on the average specialized poultry farm often becomes a burdensome problem that is not satisfactorily handled. The average annual mortality of poultry in the United States is about 20 percent. On a poultry farm with 2000 laying birds, therefore, one may expect to lose about...
The disposal of radioactive waste products is a serious problem facing scientists and the public. One solution proposed is to dump these waste products at sea, with the area of northern Oregon and southern Washington in 100 to 1,000 fathoms as one area of consideration. However, one of the problems...

This report summarizes a study which sought to provide toxicity data for pulp mills near Coos Bay through a series of toxicity bioassays. The study also surveyed benthic and beach fauna to identify macro-organisms so individual assessments of water quality requirements could be made.
The nearshore zone at Newport, Oregon was studied during the
period September, 1968 to August, 1969. Particular emphasis was
placed on those physical factors affecting the distribution of pulp mill
wastes discharged within the study area (referred to as Yaquina Bight
in this thesis). Temperatures and seawater samples were obtained...
Solid municipal waste was applied to Sagehill sand at rates of
0, 100, 200, and 400 tons/acre (0, 67, 133, and 267 tons dry matter).
Sewage sludge (2% solids) was applied at 55 gallons per ton of solid
waste. Hyslop winter wheat was planted as a cover crop in October...
Metropolitan solid wastes and sewage sludges present a serious
disposal problem for many communities. To assess the feasibility of
disposal or utilization of these waste products on soils, a study was
initiated to evaluate plant growth and soil elemental interactions on a
loamy fine sand treated with metropolitan waste. Shredded...
Channel maintenance operations in the rivers and harbors of the
United States annually require the disposal of over 320 million cubic
meters of dredge spoils. As the availability of suitable land sites
diminishes, open water disposal presents an attractive yet controversial
alternative method. For open water disposal to be acceptable,...
Waste products from industry have often been disposed in
landfills without regard for any beneficial uses of the product in
agricultural production. This research was conducted to determine
the effect of a refractory metal processing waste product on (a) soil
chemical and physical properties, (b) perennial ryegrass forage
quality and...
