Adsorption of Cu(II) and Cd(II) by Na-montmorillonite at low surface coverage in the presence and absence of water soluble complexing organic ligands

Creator:: Inskeep, William Parks
Abstract:: The formation of solution and solid complexes with heavy metals will partially determine their mobility and plant availability in soil systems. Experiments were initiated to determine the effect of pH, adsorbent and initial metal concentrations, and the presence of water soluble ligands on the adsorption of Cd and Cu by...

Association of hydrophobic organic compounds with dissolved soil organic carbon

Creator:: Ochs, Michael
Abstract:: Volatile hydrophobic compounds (HOCs) brought into soil and sediment systems represent a serious threat to the environment. Dissolved organic carbon (DOC) may exert an important influence over the total aqueous solubility and mobility of organic pollutants through their incorporation into micelles or the formation of soluble complexes. To date, however,...

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...

Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

Creator:: Phillips, Michael John
Abstract:: To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...

Comparative study of some soil characteristics of grassland and forest/grassland transition in western Oregon

Creator:: Ezenwa, Matthew Ikechuku Sunday
Abstract:: Vegetation as a soil-forming factor was studied under forest transition and grass while attempting to keep other soil forming factors constant in the western part of the Willamette Valley, Oregon. The physiographic units consist chiefly of the interior foothills and slopes formed from an old basaltic flow with some interspersed...

Incinerated sewage sludge use as a soil amendment for sweet corn (Zea mays L.)

Creator:: Mellbye, Mark Edward
Abstract:: Field and greenhouse experiments were conducted to determine the suitability of using incinerated sewage sludge ash as a soil amendment for sweet corn production on Willamette silt loam. In 1977, field plots were treated with 0, 11, 22, and 43 mt/ha of ash containing lime, in factorial combination with a...

Nitrogen and heavy metal distribution in soils utilized as sludge disposal sites

Creator:: Prothero, Gary Lewis
Abstract:: Metropolitan areas today must dispose large volumes of sewage sludge produced during the wastewater treatment process. This research was conducted to study the effect of large applications of municipal sewage sludge on (a) the distribution of N and trace elements (Cd, Cr, Cu, Mn, Ni, Zn) in the soil profile,...

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...
