Predictive mapping for the delineation of landtype association units in the Fremont National Forest, Oregon

Creator:: Malone, Melanie R.
Abstract:: Predictive Soil Mapping (PSM) has recently become an attractive method for soil scientists wishing to develop a more objective and efficient approach to mapping soils. Due to the potential PSM has for reducing the effort to produce soil maps, as well as its ability to improve the classification accuracy of...

Induced Mutation for Improving Cascade and Centennial Hop

Creator:: Getty, Brooke A.
Abstract:: Hop, Humulus lupulus L. is a dioecious perennial species. The female hop plant produces flowers that mature into ‘cones’ which are used as a raw material in the beer brewing process to impart bitterness, flavor, and aroma. The craft beer industry in the current global beer market continues to experience...

Soil Development and Organic Carbon Stocks Across a Lithosequence in the Perhumid Coastal Temperate Rainforests of Southeast Alaska

Creator:: Fedenko, Jennifer M.
Abstract:: The perhumid coastal temperate rainforests of southeast Alaska contain an abundance of soil organic carbon (SOC) that has accumulated in a wet, cool climate where forest fire disturbance is minimal and organic matter decomposition rates are low. Coastal temperate rainforests are supported by carbon-rich soils that provide ecosystem services including...
Resource Type:: Masters Thesis

Use of decision tree analysis for predictive soils mapping and implementation on the Malheur County, Oregon initial soil survey

Creator:: Hash, Sarah Jane
Abstract:: Soil surveys provide essential information for making land use and management decisions on publicly-owned lands in the semi-arid Great Basin. Soil maps produced with conventional mapping techniques are time-consuming, costly, and do not explicitly document the soil scientist's mental soil-landscape model. Predictive soils mapping using decision tree analysis (DTA) can...

Full Text:: patience, and inspiration. Thanks to my dad, John, a true hillbilly philosopher, for sharing his

Towards a national map of soil liquefaction susceptibility : modeling with heuristic and geotechnical methods

Creator:: Lindsley, Adam E.
Abstract:: This study investigates the use of predictive mapping techniques as well as geotechnical criteria in developing a multiregional soil liquefaction model and subsequent maps. The maps were produced using National Cooperative Soil Survey data, in the gSSURGO format, combined with soil liquefaction data gathered from studies, articles, and traditional seismic...

Persistence of soil organic matter in eroding versus depositional landform positions

Creator:: Berhe, Asmeret Asefaw, Harden, Jennifer W., Torn, Margaret S., Kleber, Markus, Burton, Sarah D., and Harte, John
Abstract:: Soil organic matter (SOM) processes in dynamic landscapes are strongly influenced by soil erosion and sedimentation. We determined the contribution of physical isolation of organic matter (OM) inside aggregates, chemical interaction of OM with soil minerals, and molecular structure of SOM in controlling storage and persistence of SOM in different...

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

Spatial variability of dust deposition in the Luquillo Mountains, Puerto Rico

Creator:: McClintock, Matthew
Abstract:: Dust deposition on ecosystems with highly weathered soils may provide vital rock-derived nutrients that maintain ecosystem productivity. Because of the difficulties in measuring temporally and spatially heterogeneous dust deposition over ecologically meaningful timescales, evaluations of the spatial variability in dust deposition are extremely rare. In the Luquillo Mountains of Puerto...
Resource Type:: Masters Thesis
Full Text:: -derived nutrients can be supplied with fresh minerals from long-range dust transport [e.g. Chadwick et

Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

Creator:: Keiluweit, Marco
Abstract:: Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...
