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...

Designated skid trails minimize soil compaction

Creator:: Garland, John J. and Oregon State University. Extension Service
Abstract:: Ground-based skidding may cause unacceptable damage to woodland soils when owners make no attempt to minimize the area covered with skid trails. As much as 40 percent of the area may be covered with skid trails during a single entry if you do not plan and mark them in advance.

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...

Soil compaction from low ground-pressure, torsion-suspension logging vehicles on three forest soils

Creator:: Froehlich, Henry A. and Oregon State University. Forest Research Laboratory
Abstract:: Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...
