Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...

Septic-tank drainfield performance in five Willamette Valley soils

Creator:: Wert, Stephen R.
Abstract:: Permeability, effects of age, and water table fluctuations were studied for nine drainfields in five soil types ranging from well to poorly drained. Three sites were in Willamette, one in Woodburn, two in Amity, two in Concord, and one in Dayton soils. Before permeability of drainfields could be evaluated, methods...
