Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter, J. T. Gilmour, D. C. Wolf, P. M. Gale
Arkansas Water Resources Center Technical Reports
In 1985, more than 750 million broiler chickens were produced in Arkansas. During the same year over 15 million laying chickens produced 3.6 million eggs. The waste products of these agricultural production systems, poultry litter and manure, were about 1 million metric tons. As a result of land application of these wastes, about 5,000 metric tons of annnonium N and 12,000 metric tons of mineralized nitrogen were applied to Arkansas pastures in 1985. Manures contributed about 2-3 percent of the total. The objective of this research was to quantify major components of the nitrogen cycle which influence the ground and …

Basic Steps In Laying Out A Land Tract To Optimize Forage Production And Intensive Grazing Management, Harold B. Rice, Kenneth L. Wells
Basic Steps In Laying Out A Land Tract To Optimize Forage Production And Intensive Grazing Management, Harold B. Rice, Kenneth L. Wells
Soil Science News and Views
Of the four major components of production ... land, labor, capital, and management ... land (soil) is the one which is the most basic. This ls because soil characteristics are largely "fixed" and determine, along with the climatic regime, the crop species which will perform best in a given field. For this reason. It Is basic in planning a cropping system to know root-zone physical and chemical characteristics of soils which occur on the tract being planned. With such information, crops can be matched to sell productivity to "make land as least limiting as possible." A good soils map is …

Aurealcaulis Crossii Gen. Et Sp. Nov., An Arborescent, Osmundaceous Trunk From The Fort Union Formation (Paleocene), Wyoming, William D. Tidwell, Lee R. Parker
Faculty Publications
Aurealcaulis crossii gen. et sp. nov., is based on permineralized trunks of an osmundaceous tree fern from the Paleocene Fort Union Formation from near Bitter Creek Station of southwestern Wyoming. This new species is characterized by centripetal (exarch) development of its xylem strands which form part of the leaf traces. Most of the leaf traces depart the stele as two segments that fuse into a single C-shaped petiole vascular strand outside of the outer cortex. Stipular expansions of the petiole bases of this species lack sclerenchyma, and roots arise from the lateral edges of leaf traces in the inner cortex. …
Lacustrine Deltaic Deposits Of The Sandstone Tongue Of The Wasatch Formation, Fossil Basin, Wyoming, F. Steve Petersen
Lacustrine Deltaic Deposits Of The Sandstone Tongue Of The Wasatch Formation, Fossil Basin, Wyoming, F. Steve Petersen
Loma Linda University Electronic Theses, Dissertations & Projects
Sedimentary structures and facies relations of the sandstone tongue of the Wasatch Formation in Fossil Basin, Wyoming are interpreted as indicative of a rapidly prograding bird's foot delta. Two upward coarsening siliciclastic sequences that contain bottomset, foreset, and topset beds were studied over an area of approximately 400 square kilometers. Vertical and lateral sedimentary changes within this sequence were documented by the measurement and study of over 35 stratigraphic sections. High and low angle cross-bedded sandstone units within the siliciclastic sequences thicken northward significantly before rapidly thinning and grading into the lacustrine Green River Formation. Field observations. lateral correlation of …

Paleoenvironments Of The Eocene Green River Formation (Laney Member) In The Anvil Wash Area, Southwestern Wyoming, M. Elaine Graham-Kennedy
Loma Linda University Electronic Theses, Dissertations & Projects
The study of abundant conchostracans in the Laney Member of the Green River Formation, Wyoming, has contributed to the resolution of the controversy over the depositional environment of finely laminated sediments. Conchostracans that typically live in ephemeral pools, pulmonate gastropods that require oxygenated water and freshwater ostracods indicate deposition of finely laminated sediments in a well oxygenated, shallow, freshwater lake. Mineralogical evidence indicating that Lake Gosiute was primarily fresh during deposition of the upper portion of the Laney Member includes predominance of calcite over dolomite and the clay composition of diagenetically altered tuffs. The minor amount of dolomite is detrital …

Rise To Power Of Senator Joseph R. Mccarthy: Reflections Of The Cold War Mccarthy Era In American Film, Scott Lainer
Honors Theses
The common bond between much of the film industry and Joseph McCarthy was insecurity and the drive for national approval. If one grasps the specific characteristics of McCarthy the man, and the methods of these politically "inspired" movies, we can to better place the period into context and acknowledge the fact that, if the citizenry is not aware, and is again caught by an ever-building wave of trickle down sentiment, the 1950s might not prove to be an isolated period in American history. Insecurity was not a fifties novelty. It still exists, and could potentially escalate anti-Communist policy and sentiment …

Hydrogeology And Hydrochemistry Of Springs In Mantua Valley And Vicinity, North-Central Utah, Karen C. Rice
Hydrogeology And Hydrochemistry Of Springs In Mantua Valley And Vicinity, North-Central Utah, Karen C. Rice
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Chemical and tritium analyses of groundwater, precipitation and discharge records, fracture orientations, lineaments, and structural, stratigraphic, and topographic relationships have been used to describe the groundwater systems of Mantua Valley, north-central Utah. Groundwater flows through fractured Paleozoic quartzites and carbonate rocks and discharges from eleven perennial springs in Mantua Valley. Permeability in quartzites is the result of intense faulting and jointing. Groundwater in carbonate aquifers flows through fractures and/or fractures modified by solution and discharges as relatively large springs (up to 227 liters per second). Neogene normal faulting, rather than extensive karst processes, has produced valleys which are closed or …
Control Measures For Manganese Toxicity Of Burley At Transplating Time, Kenneth L. Wells, J. L. Sims
Control Measures For Manganese Toxicity Of Burley At Transplating Time, Kenneth L. Wells, J. L. Sims
Soil Science News and Views
Manganese (Mn) toxicity of burley tobacco is viewed by tobacco specialists in Kentucky as the greatest single factor which reduces yields. Estimates are that this problem adds 30 to 50 million dollars to the cost of burley production because of the greater acreage (and all associated costs) required by growers to produce their allotment. And, even though the cause and cure of Mn toxicity has been known for about 50 years, many growers are caught each year at transplanting time with no knowledge as to whether Mn toxicity may be a problem in their fields. The solution to Mn toxicity …
Petrology Of The Middle Cambrian Langston And Ute Formations In Southeastern Idaho, Daniel T. Rogers
Petrology Of The Middle Cambrian Langston And Ute Formations In Southeastern Idaho, Daniel T. Rogers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Middle Cambrian Langston and Ute formations were studied in the northern portion of the Bear River Range and the south-central part of the Portneuf Range in southeastern Idaho.
The rocks of the Langston and Ute formations were divided into 17 different rock types. The 17 rock types were formed within four recognizable lithofacies: I) Shoal - or Coastal-Peritidal Carbonate Complex; 2) Agitated Shoal; 3) Inner Marine Shelf; and 4) Outer Marine Shelf. Clastic sediments belonging to the Spence Shale Member of the Langston Formation (outer marine shelf) were deposited over the carbonate complex. A transgressive sequence marks the base …

Petrology Of Pliocene (?) Basalts Of Curlew Valley (Box Elder Co.), Utah, Steven Brent Kerr
Petrology Of Pliocene (?) Basalts Of Curlew Valley (Box Elder Co.), Utah, Steven Brent Kerr
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Basalt outcrops in Curlew Valley consist of several flow remnants and eruptive centers situated along the valley margins. Basalt is also found in association with salic rocks that erupted in the central portion of the valley. The basalts are of probable Pliocene age and were erupted during a period of active extensional tectonics. Since their emplacement, the basalts have been extensively eroded and downfaulted. The present morphology reflects the erosional and depositional processes of prehistoric Lake Bonneville.
Twelve samples were analyzed chemically for major oxides, trace elements, and rare-earth elements. The basalts form a hypersthene normative series ranging from olivine …

Spatial And Temporal Landslide Distribution And Hazard Evaluation Analyzed By Photogeologic Mapping And Relative-Dating Techniques, Salt River Range, Wyoming, John B. Rice Jr.
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The distribution of landslide type and age was analyzed to determine the causes and timing of landsliding, and to assess landslide hazards in the study area. 1173 landslides and zones of landsliding were mapped on 1:15,840 scale air photos and designated by their style of movement and age. Slides were assigned to one of four age classes based on their degree of morphologic modification visible on air photos. Relative dating (RD) methods previously applied to glacial deposits were used to refine and calibrate the age classification.
Eleven RD para meters were measured on 21 rockslide and 19 glacial deposits. Cluster …

Benthic Foraminiferal Assemblages From Mexican Continental Shelves, Maria De La Luz Mata
LSU Historical Dissertations and Theses
The recent benthic foraminifera 1 fauna of the continental margins of Mexico (Gulf of Campeche and Gulf of Tehuantepec) was studied. Surficial sediment samples (lOcc) were collected using a Shipeck dredge and were stained with Sudan Black "B" in order to differentiate the living fauna from the death assemblage. In the 41 samples from the Gulf of Campeche, 279 species were found in the total assemblage in water depths ranging from 9 to 586 m. In the 22 samples in the Gulf of Tehuantepec, 132 species were identified from the total assemblage in water depths of 20 to 180 m. …

Rheologic Properties And Kinematics Of Emplacement Of The Chaos Jumbles Rockfall Avalanche, Lassen Volcanic National Park, California, Dean B. Eppler, Jonathan H. Fink, Raymond Fletcher
Geology Faculty Publications and Presentations
The Chaos Jumbles is a rockfall avalanche deposit that was emplaced by three separate events ~ 300 years ago. Deposits from each event are distinguishable on the basis of morphology, size variation of large dacitic surface clasts, and by the color of both the matrix and entrained dacitic blocks. Steep lateral and distal deposit margins and surface features such as folds and apparent strike-slip faults indicate that each rockfall avalanche had a finite yield strength and was being actively deformed and sheared throughout the body of the moving deposit, rather than strictly along a basal surface. Kinematic analysis of the …
Is Row Fertilizer Necessary For No-Till?, Lloyd W. Murdock, William O. Thom
Is Row Fertilizer Necessary For No-Till?, Lloyd W. Murdock, William O. Thom
Soil Science News and Views
Row fertilizer is an old practice which has been in and out of favor over the years. The use of row fertilizer and its benefits vary with the conditions. The efficiency of applied fertilizer is greatly increased by putting it beside the row and is very helpful on soils with a low soil test. For soils testing medium or high, a sufficient amount of nutrients exist in the soil so that additional fertilizer applied in the row will not increase yields. Regardless of soil test. row fertilizer will usually increase the vigor and early growth of a crop. Most of …

The Effect Of Well Efficiency On In-Situ Permeability Test Results, Scott T. Dennis
The Effect Of Well Efficiency On In-Situ Permeability Test Results, Scott T. Dennis
Masters Theses
The purpose of this study was to determine what effect well efficiency has upon the results of in-situ permeability tests.
Several in-situ permeability tests were performed on wells during various stages of their development. The well efficiency was determined each time an in-situ test was performed. An accurate value of permeability was determined by performing local aquifer pumping tests. The accuracy of the results of the in-situ tests with respect to the aquifer pump test results were then compared to the efficiency of the well at the time of the test.
Test results showed that a linear relationship exists between …
Structural Geology And Geothermal Investigation Of The White Sulphur Springs Area, Montana, William G. Gierke
Structural Geology And Geothermal Investigation Of The White Sulphur Springs Area, Montana, William G. Gierke
Masters Theses
Sevier thrusting in the White Sulphur Springs area was associated with left-lateral movement along the Lewis and Clark line . During Middle Miocene time, the Lewis and Clark line exhibited right-lateral movement, forming extensional features that either truncated Sevier structures or followed preexisting Sevier zones of weakness.
The Smith River Valley is a pull-apart basin that is filled with Tertiary volcanic ash and clay-rich sediments that are thermally nonconductive relative to surrounding rocks.
Hydrothermal activity in the area is associated with a structurally controlled circulation system accompanied by a high thermal gradient. Thermal discharge is constrained along the north-trending White …
