Nitrous Oxide Loss From Poultry Manure-Amended Soil After Rain, Mark S. Coyne, A. Villalba, Robert L. Blevins

Plant and Soil Sciences Faculty Publications

Land application of poultry wastes in Kentucky will increase as the broiler industry grows. If poultry manure stimulates N₂O loss from soil it will reduce the fertilizer N value of this waste. In contrast, stimulated N₂O loss in grass filter strips receiving the runoff from manured fields could help reduce contamination of surface water by NO⁻₃. Our objectives were to determine (i) if poultry manure stimulated N₂O loss in soil after rainfall and (ii) if there was an edge-of-field effect on N₂O loss in grass filters intercepting runoff from …

Grasslands: An Introduction, Kathleen H. Keeler

Great Plains Quarterly (through 2013)

"Grasslands" was the subject of the seventeenth annual symposium of the Center for Great Plains Studies, held at the University of Nebraska-Lincoln, in April 1994. Grasslands are so basic to the Great Plains experience as to be invisible. If you stand here in eastern Nebraska, it is so far in any direction across grasslands to any other landscape (a cornfield is a planted grassland, after all) that the role of grasslands in our lives does not seem worth considering. Local variation is much more visible. You can't see the prairie for the grasses, to adapt the idiom. And yet, grasslands …

Weed Suppression With Grazing Or Atrazine During Big Bluestem Establishment, B. Keith Lawrence, Steven S. Waller, Lowell E. Moser, Bruce Anderson, Larry L. Larson

Department of Agronomy and Horticulture: Faculty Publications

Weed competition is a major factor causing warm-season grass seeding failures in rangeland and cropland. With a limited number of herbicides available for weed control, grazing may reduce competing vegetation in seedings and serve as an alternative to herbicides. Many immature needy forbs and grasses are palatable to cattle and contain high nutrient levels. Research was conducted (RCBD, 4 reps) comparing grazing by yearling cattle with chemical suppression [atrazine (6-chloro-N-ethyl-N’- (methylethyl)-1, 3, 5-triazine-2, 4-diamine)] for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedlings at Mead, Nebr. on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic …

Demography, Reproduction, Diet And Crop Depredation In Three Species Of Rodents In Natural And Irrigated Fields In Nigeria, Safianu Rabiu

Biological Sciences Theses & Dissertations

Rodent populations of Arvicanthis, Mastomys and Tatera were studied during July 1990 to August 1992 in both natural and irrigated savannah fields of northern Nigeria. Tatera was entirely absent from the irrigated fields. Irrigation enhanced higher rodent population densities in the magnitude of three to four times over densities in the natural field. Arvicanthis was the most abundant of the three species in both sites. Tatera was the least common in the natural site. Adult survival rates in Arvicanthis and Tatera were significantly higher than Mastomys. Survival rates of both adult and young differed between the wet and dry …

Stomatal Characterization Of Grass Leaves By Four Preparation Techniques, Val J. Anderson, John S. Gardner, Joyce Phillips Hardy

Faculty Publications

Four leaf preparation techniques (air drying, tetramethylsilane air drying, critical point drying, and freeze substitution) used in scanning electron microscopy (SEM) were evaluated with respect to the degree of cellular distortion they produce in stomatal guard cells of leaves of Dactylis glomerata and Elymus canadensis. Surface morphological distortion and cuticle disruption in the air-dried and tetramethylsilane air-dried leaves, and cuticle disruption within the critical point-dried tissue made it difficult to obtain measurements.The freeze-substituted tissue experienced little cuticle disturbance, and the cellular morphology appeared normal. The length of the guard cells did not significantly differ between the air-dried, tetramethylsilane air-dried, critical …

Transitions In Masculinity And Hemingway's Developed "Code", Daniel Polk

Honors Theses

The "Hemingway Code" is much more than two words that fit nicely together for a scholar's usage; the words signify a much deeper championing of masculinity, almost a haunting presence. For Ernest Hemingway living life every day, every moment with its fullest masculine fervor, became an obsession, a never-ending quest to be at one with the attitude of never complaining, never crying out, panicking, thinking too much, or regretting. To live a manly life in a series of tactical victories, performed with steadfast ritualistic mannerisms, is to embody masculinity, and therefore the "Hemingway Code."

Research On Plant Disease And Pest Management Is Essential To Sustainable Agriculture, R. James Cook, Clifford J. Gabriel, Arthur Kelman, Sue Tolin, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

In the United States, a country with food in great abundance, it is difficult to realize that, were it not for the current level of plant disease and pest management, most human resources would be needed to obtain enough food and other plant and animal products merely to survive. Instead, there are surpluses, markets for many agricultural products are depressed, and funds available for research on plant disease and pest management-and for agricultural research generally-have plateaued or are declining. Why does the United States need more research on plant disease and pest management? Because the health and productivity of the …

Spectral Reflectance From A Broccoli Crop With Vegetation Or Soilias Background: Influence On Immigration By Brevicoryne Brassicae And Myzus Persicae, Michael J. Costello

Horticulture and Crop Science

Light reflectance in five wavebands of the spectrum was measured from broccoli (Brassicae oleracea var.botrytis [L].) interplanted with leguminous cover crops (cover crop background) or broccoli grown as monoculture (bare soil background), and fertilized with compost or synthetic fertilizer. Alate Brevicoryne brassicae (L.) and Myzus persicae (Sulzer) (Homoptera: Aphididae) were monitored in yellow pan water traps and on broccoli leaves. Reflectance intensity was higher with a background of bare soil at all wavebands except blue (400–455 nm) in the early-season. Intensity decreased as broccoli canopy cover increased at all wavebands except blue and green (515–550 nm), declining-most dramatically in …

An Economic Study Of The Relative Profitability Of Alfalfa Production And Marketing Practices, David Claycomb

Masters Theses & Specialist Projects

The seasonality of the price of alfalfa hay in Kentucky was studied as well as the potential cost or profitability of storage of this hay. Economic comparison of alfalfa hay production to other farm enterprises was carried out. In addition, an estimate of the value of two qualities of alfalfa hay was calculated based on 1991 prices. The analysis of 41 years of marketing data demonstrated significant differences (P<.01) in price with seasonal lows in June/July and a steady increase in price to a high in March. In general (based on $100 per ton hay and 12% interest) the alfalfa hay producer could lose from $5 to $10 storing hay and selling at a later date. There were some specific conditions where he might have realized a return to storage of $0.16 to $1.48 per ton. A further evaluation of average (KY Feeder) and good (KY Pride) quality hays indicated that current prices of $70-$75 and $100 per ton respectively were the prices where a dairyman would be able to include this hay in the cow's total diet. Even with problems of quality and quantity of alfalfa hay, the economic returns to the production of alfalfa hay were favorable when compared to other crops in Kentucky with the additional benefit of alfalfa being a crop that can result in reduced soil erosion from sloping land. Returns above variable costs can be from $120 to $400 per acre depending upon yield and sale price. However, an understanding of seasonality of price as well as storage costs need to be considered by alfalfa hay producers to assure realizing the above returns.

Fecal Bacteria In Agricultural Waters Of The Bluegrass Region Of Kentucky, J. M. Howell, Mark S. Coyne, P. L. Cornelius

Plant and Soil Sciences Faculty Publications

Agricultural runoff influenced by nonpoint pollution frequently exceeds the USEPA standards for bacterial contamination of primary contact water (200 fecal coliforms/100 mL). Few studies have evaluated the effect of cattle (Bos taurus) grazing on fecal contamination of ground water in the karst topography of central Kentucky. Our objectives were to: (i) observe the extent and pattern of fecal bacteria in agricultural waters from two central Kentucky watersheds; (ii) determine if monthly sampling accurately assessed the extent and variability of fecal contamination; and (iii) assess the fecal coliform/fecal streptococci ratio (FC/FS) as an indicator of fecal bacteria source.
