The mobility and plant availability of boron in selected western Oregon soils

Creator:: Parker, David R.
Abstract:: Several crops grown in the Willamette valley of western Oregon respond to applications of boron fertilizers. The acid, highly-leached soils of this area are naturally low in plant-available B. Application of B to the soil annually or at less frequent intervals is currently recommended, but the fate of applied B...

Relationships among phosphorus soil tests, forms of soil phosphorus, and plant uptake of phosphorus for selected southwestern Oregon soils

Creator:: Doerge, Thomas A.
Abstract:: A diversity in climate, geologic parent material, and soil characteristics exist in Jackson, Josephine, Coos, and Douglas Counties of southwest Oregon. Previous field trials and soil testing results have revealed uncertainties as to the phosphorus (P) status of the soils in this area. Twenty-four sites from nine agriculturally significant soil...

Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:: McCarthy, Michael J.
Abstract:: Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...

The fertilizer value of shrimp and crab processing wastes

Creator:: Costa, Robert Edward
Abstract:: The Federal Water Pollution Control Act Amendments of 1972 prohibits the discharge of seafood processing solid wastes into navigable waters after July 1, 1977. Oregon shrimp and crab processors must use other methods of disposal for the 15 to 30 million pounds of solid waste generated annually. The application of...

Fertilizer requirements of wheat grown under conservation tillage

Creator:: Nibler, Francis J.
Abstract:: Nitrogen (N), phosphorus (P), and sulfur (S) fertilization trials with Stephens winter wheat (Triticum aestivum L.) were conducted on the Columbia Plateau under minimum and no tillage conditions. The crop rotation was either wheat-summer fallow (summer fallow) or wheat-wheat (recrop). Nitrogen variables included: N rates, N timing, and N source...

Effects of lime and VA-Mycorrhiza interactions on growth responses of sweetgum seedlings

Creator:: Davis, Elizabeth Anne
Abstract:: 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...

Nitrate nitrogen accumulation and distribution in the soil profile during a fallow grain rotation as influenced by different levels of soil profile moisture

Creator:: Aktan, Selman
Abstract:: The effect of different soil moisture levels on the amount and location of NO₃ -N accumulation in the soil profile were studied. The cultivars used in this study were Mcdermid, a soft white winter wheat, and Hudson, a medium early winter barley. Moisture treatments simulating dry, normal and wet fallow...

Nitrogen fertilizer rate and application timing effects on growth and seed-oil yield of meadowfoam

Creator:: McGahuey, Michael L.
Abstract:: Meadowfoam has been identified as a potential oilseed crop for production on poorly drained soils in areas with cool, moist winters. The effects of N fertilizer on meadowfoam (Limnanthes alba Benth.) have been studied in Oregon and Maryland, but the results have not been consistent with respect to the effects...
