Modeling Of Soil Water Flow And Root Uptake, V. Rasiah
Modeling Of Soil Water Flow And Root Uptake, V. Rasiah
Electronic Theses and Dissertations
The soil water pressure head, h, versus soil water content, 9, and the hydraulic conductivity, K, versus θ, relationships appear as functional coefficients in the non-linear partial differential water flow model. Before the flow equation can be used to simulate the flow of water through soils, the h versus θ and K versus θ relationships must be established. This requires the estimation of the parameters that describe the h versus θ and K versus θ functional relationships. In-situ water retention and hydraulic conductivity measurements were determined from the knowledge of initial and boundary conditions and water content profiles during drainage. …

Technology And Economics Of Commercial Scale Ethanol Production From Fodder Beets, William Ray Gibbons
Technology And Economics Of Commercial Scale Ethanol Production From Fodder Beets, William Ray Gibbons
Electronic Theses and Dissertations
Fodder beets yield two to three times more fuel ethanol per hectare than corn. This increased productivity should reduce feedstock costs and, consequently, ethanol production costs. The major factor that has limited use of this crop is the lack of a proven technology to process fodder beets -- economically and energy efficiently -- to fuel ethanol on a commercial scale. Research reported herein rectifies this situation by examining the technical and economic feasibility of community scale fuel ethanol production from fodder beets using two novel, continuous fermentation systems solid-phase fermentation and diffusion fermentation. Laboratory scale, batch fermentation trials were first …

Growth And Development Of Oat (Avena Sativa L.) Cultivars In Response To Water Stress, Abdel-Fattah H. Belal
Growth And Development Of Oat (Avena Sativa L.) Cultivars In Response To Water Stress, Abdel-Fattah H. Belal
Electronic Theses and Dissertations
Water stress occurs frequently in the North Central Plains and causes significant reductions in plant growth, development and grain yield. These effects of water stress apparently are dependent on the ability of plants to adapt to less than optimal environments. Plant water potential is dynamic, changing not only with the soil water content and atmospheric conditions, but also with the stage of growth. When plant water potentials become limiting, various physiological processes associated with plant growth, development and final yield are affected. The reduction in productivity in semi- arid environments is directly related to the inability of crop plants to …

Influence Of Geomorphological Origin Upon Macroinvertebrate Community Structure In Black Hills Streams, Matthew Lechner
Electronic Theses and Dissertations
The purpose of this study was to test a stream classification system proposed for the Black Hills National Forest. Stream physiochemical characteristics and macroinvertebrate community structure were compared among three geomorphically distinct landtype associations in the Black Hills. Stepwise disciminant analysis identified five physiochemical variables, which explained 90% of the variability among landtype associations. The classificatory discriminant procedure correctly reclassified 47 of 52 stations based on the five discriminating invertebrate taxa. Each landtype association was sufficiently different in stream physiochemical characteristics to permit classification. Macroinvertebrates exhibited distributional patterns related to changes in geomorphic structure and stream order, among landtype associations. …
