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...

Liming requirement of selected Willamette Valley soils

Creator:: Peterson, Paul William
Abstract:: There are two major problems associated with soil acidity and lime response investigations: A. Determining how much lime (100% "available" CaCO₃ equivalent) is required to raise a soil pH (or degree of acidity) from its existing level to a specified level - presumably where need for lime is eliminated. B....
