A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....
Elliptical borehole enlargements or "breakouts" caused by systematic spalling of a
borehole wall due to regional maximum horizontal stresses were identified in 18 wells
drilled in the Coast Range and Willamette Valley of western Oregon. The breakouts
generally indicate a NNW to NNE orientation of maximum horizontal compression
(oH[subscript max])...

Many organizations structured in the rational-analytical paradigm of resource management are becoming increasingly aware that new management approaches are needed. Particularly in a rapidly changing environment, organizational learning is important for promoting an organization's ability to...
This study was conducted to investigate the differences of the
profile distribution of free iron and free manganese and the reduction-oxidation changes in soils of the Willamette drainage sequence.
Based on the results of the chemical analyses, free iron and
free manganese distributions in these soils were governed to a...
