Determining the Minimum Treatment Area and Importance of Soil Irrigation for Solarizing Soil Infested with Phytophthora spp.

Creator:

Bennett, Logan L.

Abstract:

Nurseries are an important part of the agriculture industry of the United States. The nursery industry provides ornamental, forest, restoration and specialty products to many markets in N. America. The disease sudden oak death, caused by Phytophthora ramorum, has devastating environmental and economic impacts on forested land, the urban-forest interface,...

Masters Thesis
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...

Masters Thesis
Characterization of hydrologic parameters and processes in shrink-swell clay soils

Creator:

Stewart, Ryan D.

Abstract:

Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...

Response of soil microbial communities to physical and chemical disturbances: implications for soil quality and land use sustainability

Creator:

Chaer, Guilherme M.

Abstract:

The objectives of this thesis were to evaluate the responses of soil microbial communities to physical and chemical disturbances, and associate these responses with soil functional stability and changes in soil quality. The first study consisted of application of heat shocks (HS) to soils with contrasting land use history to...
