Zinc-phosphorus relationships in five plant species

Creator:: Henning, Stanley John
Abstract:: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses...

Availability of phosphorus in central Oregon soils in comparison with selected Oregon soils

Creator:: Araos, Jose Fernando
Abstract:: The objectives of this study were to evaluate and compare the availability of native and applied P in Central Oregon pumice soils with that in Willamette valley soils and calcareous soils from Eastern Oregon. The experimental work to meet these objectives included laboratory and greenhouse studies. The removal of P...

The relationships between zinc, iron, and phosphorus in sweet corn

Creator:: Hay, James Ronald
Abstract:: The relationships between zinc, iron, and phosphorus in sweet corn were investigated under field and greenhouse conditions. The soils used in this study (both acid and calcareous) were low in available zinc and phosphorus. The experiments received standard, uniform rates of nitrogen potassium, magnesium, and sulphur. Corn was used as...

Chemical properties of soils related to seasonal fluctuations in exchangeable potassium

Creator:: Etter, Harold Mac Donald
Abstract:: Representative sites of the Dayton, Woodburn, Jory, Quillayute, Astoria, Willamette, Walla Walla, Deschutes, Laki and Owyhee soil series were investigated for seasonal changes in exchangeable potassium in air dry samples. No consistent seasonal variations were found which could be attributed to wetting and drying in the field. Cropping reduced the...

The effect of selected potassium salts on the availability of soil manganese

Creator:: Westermann, D. T. (Dale Thomas), 1941-
Abstract:: Incubation experiments with an acid poorly drained soil have shown that the application of neutral soluble salts influenced the level of extractable Mn. The application of a salt which lowered the soil pH either increased the extractable Mn or retarded the oxidation and/or fixation of extractable Mn. This effect was...

Effects of sulfur on yield and plant sulfur of subterranean clover

Creator:: Loqa, Harith Jabbouri, 1937-
Abstract:: Subterranean clover was grown in nutrient solution and S deficient Steiwer soil in the greenhouse. Plants were harvested at 15, 30, 45 and 60 days after emergence. When subterranean clover was grown in nutrient solution significant yield response to each increment of added sulfate (SO₄-S) occurred in 15, 30, 45...

Subterranean clover yield and nutrient content as influenced by soil molybdenum status

Creator:: Bhella, Harbans Singh
Abstract:: During the Spring of 1969, 47 surface soil samples (0 to 15 cm) as well as foliage samples of subterranean clover were collected from 32 selected western Oregon pastures, in an effort to determine their molybdenum status and to evaluate the use of anion exchange resin method as a means...
