Creator:: Seeno, Elizabeth A.
Abstract:: Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...

Creator:: Osterloh, Kristopher Richard
Abstract:: Andic soils (aka Andisols) have unique properties that are important to society. For soil scientists, the genesis and taxonomy of Andisols is often confused because they can form in both volcanic and non-volcanic material. This dissertation seeks to address such confusion by looking at andic soil development in the Cascade...

Creator:: Almquist, Vance Warner
Abstract:: This dissertation reports on four related, though separate projects. The first project details the process of carrying out a digitally augmented soil mapping (DSM) effort alongside an ongoing survey in Oregon's Ochoco National Forest (ONF) using a Random Forest algorithm. The second chapter describes a initial soil survey in Oregon's...

Creator:: Hynicka, Justin D.
Abstract:: Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...

Creator:: Knapp, Dante L.
Abstract:: Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...

Abstract:: The toxicity of aluminum (Al) to wheat (Triticum aestivum Host) was studied under controlled conditions using a technique designed to evaluate the recovery of root growth following a relatively brief (48 hour) exposure to nutrient solutions containing Al, When wheat seedlings were exposed to a minimum critical concentration of Al,...
