A study, consisting of two sequential greenhouse experiments, was
designed to determine the effects of soil liming upon the fungal
partner in a mycorrhizal association. A Willamette Valley foothill
soil, of the Jory series, was limed in increments to achieve a range
of acidity and alkalinity. The P-deficiency and P-fixing...
Persistent levels of high turbidity in the outflow from the
Prineville Reservoir led to development of relationships between
watershed soils, land use, and resource management and water
quality in the Upper Crooked River, Central Oregon.
Seven stations, strategically located for measurement of runoff
volume and water sample collection, were established...
Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...
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...
