N fertilizer effects on soil solution Mn and Mn response of barley and oats

Creator:: Petrie, S. E.
Abstract:: A series of field experiments was established in 1978, 1979, and 1980 on Lower Klamath Lake where Mn deficiency of oats had been observed in previous years. The pH of the soils ranged from 7.6 to 8.3 and the organic matter content was between 17 and 19%. The objectives of...

Diagnosis and correction of copper deficiency of small grains in Oregon

Creator:: Kresge, Paul Owen
Abstract:: Field-plot experiments and pot culture techniques were used to investigate reported Cu deficiency in certain Oregon organic soils. Field experiments were established in 1973 and 1974 on an acid peat soil and two alkaline muck soils near Klamath Falls, The effect of rates of from 0 to 45 kg Cu/ha...

Selective inhibition of ion absorption by uranyl

Creator:: Mason, Benjamin J.
Abstract:: The research presented in this thesis evaluated the effects of uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due to the biological importance of Na and K, these two ions were studied in the greatest detail. The results of this research showed that, at UO₂⁺⁺ concentrations...

The effect of fertilizer treatments on nutrient uptake, yield, and quality of winter wheat on selected western Oregon soils

Creator:: Murarka, Ishwar P.
Abstract:: A series of nine experiments designed to evaluate the effects of N, P, and K fertilizers on the production of wheat in western Oregon were seeded in the fall and carried through the 1967 growing season. The experimental sites were selected to represent different soils that are used for production...

Potash fertilizer effects on yield, hollow heart, and nutrient levels in potato tubers and petioles

Creator:: McBride, Robin L.
Abstract:: Potash rate and source effects on tuber yield and quality (hollow heart, size, and processing quality), and nutrient (K, Ca, Mg, and C1) concentrations in petioles and tubers were evaluated in three experiments, two in the Columbia Basin in Oregon (McDevitt and Levy) and one in Central Oregon (Powell Butte)....

The effects of nitrogen, potassium and chloride on nutrient composition in Russet Burbank potatoes (Solanum tuberosum)

Creator:: Murarka, Ishwar P., 1942-
Abstract:: Three greenhouse experiments were designed to measure the effects of N, K and Cl on the nutrient uptake by Russet Burbank potatoes (Solanum tuberosum). A Deschutes sandy loam soil from Powell Butte area in Central Oregon, low in potassium, was used to study these effects. Nitrogen applications produced significant increases...

Identification of potential copper and molybdenum livestock nutrition problems with forage analysis

Creator:: Kresge, Paul Owen
Abstract:: Copper deficiency and Mo-induced Cu deficiency are nutrition problems of ruminant livestock in the Burns and Klamath Falls area of Oregon. Chemical analysis of plant and soil samples was used to survey Cu and Mo levels in forage in these areas. The objectives were to assess the possibility of animal...

Biological assessment of soils for potential development of take-all root rot

Creator:: McGeehan, Steven L.
Abstract:: Take-all root rot (Gaeumannomvces araminis var.tritici) is a major disease of wheat (Triticum aestivum) in western Oregon. Control of take-all is dependent on management practices such as crop rotation and soil fertility-plant nutrition relationships. The objective of this study was to develop a bioassay that could measure the influences of...

Effects of nitrogen applied on wheat straw on winter wheat (Triticum aestivum L.) yields in western Oregon

Creator:: Caputo, John Anthony
Abstract:: Nitrogen deficiency during the winter where winter wheat (Triticum aestivum L.) follows wheat and large amounts of straw have been plowed down has been a factor limiting yield in the Willamette Valley of western Oregon. Field experiments were established to determine if an application of N on the stubble or...

Chloride fertilizer and soil pH effects on nitrification rate and soil solution constituents

Creator:: Roseberg, Richard J.
Abstract:: Chloride containing fertilizers are used to reduce the severity of take-all root rot of wheat in western Oregon and appear to reduce nitrification in moderately acid soils. Objectives of this study were to determine if nitrification is inhibited by the Cl ion, increasing soil solution ionic strength, or changes in...
