Factors influencing residual stand damage levels due to cable thinning of coniferous stands in western Oregon

Creator:: Caccavano, Michael P.
Abstract:: The purpose of this study was to determine the significant variables influencing the damage levels sustained by the residual stand after skyline thinning of coniferous stands. Damage levels were measured in ten study areas in western Oregon that had received their first commercial thinning. For this post-logging study, 38 units...

The effect of ration formulation on the subsequent generation of volatile gases and odors from bovine waste

Creator:: Kellems, Richard O.
Abstract:: The objective of this study was to determine the effect that ration formulation has on volatilization of gases and offensiveness of the odor associated with the wastes produced from Holstein replacement heifers. Six separate experiments were conducted to study the relationships between different variables on the release of hydrogen sulfide,...

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

An analysis of two adjacent agricultural watersheds in west central Oregon

Creator:: Schoeneberger, Philip James
Abstract:: Two small adjacent watersheds on the west-central edge of the Willamette Valley of western Oregon were studied. Information was gathered on existing conditions to determine the suitability of the two watersheds for a paired-watershed study design. A soil survey was conducted using slightly modified soil series previously established for the...

Diclofop in runoff from agricultural watersheds in a high winter rainfall zone

Creator:: Hickman, John Spencer
Abstract:: Diclofop-methyl [me yl 2-(4-(2,4-dichlorophenoxy) phenoxy) propanoate] hydrolysis, degradation, and leaching were studied in field and laboratory experiments. Greater than 75% of the applied diclofop-methyl hydrolyzed to diclofop in 2 days at 4°C, the prevailing soil temperature during western Oregon winters. Degradation beyond the diclofop molecule, also an active herbicide, was...
