Abstract:: The OSU Extension Soil Sensitivity Database lists nonirrigated and irrigated soil sensitivity ratings for every map unit of every soil survey in Oregon. These ratings were developed for the Oregon Water Quality Decision Aid, a tool for evaluating groundwater vulnerability to pesticide contamination.

Abstract:: A Land Evaluation and Site Assessment (LESA) Model was developed for the forested soils of Lane County, in western Oregon, based on soil potential ratings and indexes of parcel size and adjacent and surrounding land use conflict. Lane County's economy is heavily dependent on resource production uses of land for...

Creator:: Hoppe, Diane A. S.
Abstract:: Distribution and characteristics of soils were determined across a series of six coastal terraces in Curry Co., Oregon. Classification of soils and interrelationships of properties were determined. Soil-landscape relationships were examined and soil profile development related to relative ages of terraces. Ten pedons were sampled from five terraces of Pleistocene...

Abstract:: The morphology and genesis of soils of the Willamette series and of some Willamette-associated soils and their relationships to geomorphic surfaces were studied in an area near McCoy, Polk County, Oregon. Influences of regional extent, such as climate and parent material, were related to the soils and landforms. The soils...

Creator:: Sun, Yulin
Abstract:: Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...
