Hydrophobicity of Cindery Typic Cryorthents

Creator:

Evans, Lynn B.

Abstract:

The hydrophobicity of soils of the Deschutes National Forest was studied. The soils are Cindery Typic Cryorthents, formed in cinders and ash from Mt. Mazama. Ponderosa pine is the dominant overstory vegetation. Of particular interest was the effect of prescribed burning on hydrophobicity. Fire has been shown to cause a...

Nitrate and pesticide transport under pear production in clay and sandy soil

Creator:

Cao, Weidong

Abstract:

Groundwater contamination on irrigated land is of concern in this nation and around the world. In order to reduce the potential of groundwater contamination by agricultural practices such as irrigation, fertilizer and pesticide application, vadose-zone monitoring and sampling are needed. The main objective of this study was to evaluate impacts...

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,...

Remediation of heavy-metal contaminated soils using succinic acid

Creator:

Kaul, Arvind

Abstract:

Succinic acid, a low molecular weight dicarboxylic acid was used to leach out heavy metals from Willamette Valley soil (contaminated separately with lead, copper, and zinc) in form of water-soluble organo-metal complexes. The research tasks included developing synthetic contaminated soils representative of those found at Superfund sites and making heavy...

Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

Creator:

Pérez, Angela L.

Abstract:

Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

Nitrate and water under terraced dryland wheat production in Oregon

Creator:

Strock, Jeffrey S.

Abstract:

Dry land agriculture using summer fallow is a common crop production practice in the Columbia Plateau region of eastern Oregon. Farmed-over level terraces are used to control surface water runoff and soil erosion. More than 70 percent of the average annual precipitation around Pendleton, Oregon (350 - 400 mm) falls...

Abstract:

Implements for tilling compacted forest soils were tested on sites logged with ground-based machines in Oregon. The sites covered a variety of soil conditions ranging from a clay loam to a rock7 2C2 iplemeflts tested included disk harrows (four aies), brusa blades (three sites), standard subsoiler tines (two sites), wing.-...

Influence of log truck traffic and road hydrology on sediment yield in western Oregon

Creator:

Miller, Rebecca H.

Abstract:

An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...
