Extending The Season For Sustainability In Utah, Britney Hunter
Extending The Season For Sustainability In Utah, Britney Hunter
Undergraduate Honors Capstone Projects
The importance of providing fresh produce on a local level is becoming a widespread consideration among people concerned with the character of their food. For regions without an opportune growing climate, extending the growing season can drastically advance productivity. High tunnels are one way to effectively and profitably extend the growing season in cold climates. The benefits of growing in a high tunnel go beyond raising the temperature. High tunnels contribute to higher quality small fruits and vegetables. The benefits of growing in high tunnels have been explored in other states and could be exploited by Utah growers. Utah's climate …
Bioavailability/Toxicity Of Iron From Aerobically Processed Organic Fertilizer, Stacey Marie Wilson
Bioavailability/Toxicity Of Iron From Aerobically Processed Organic Fertilizer, Stacey Marie Wilson
Undergraduate Honors Capstone Projects
For an undergraduate Honor's project, I worked under the direction of Dr. Jeffery Hall to determine the bioavailability and toxicity of iron from Milorganite® fertilizer, an aerobically processed organic fertilizer. The Milorganite® Company is a subsidiary of the Milwaukee Municipal Sewage District and produces a fertilizer of high iron content (approximately 5-7%). The high iron content has resulted in concern about the toxic potential, which until now was unknown. This thesis paper will explain iron chemistry, bioavailability, requirements, absorption, toxicity, and treatments, followed by a description of fertilizer types and contents. This will be followed by a description and reasoning …

Characterization Of Dielectric Properties Of Earth Materials At Low Frequencies, Tarrah Dawn Henrie
Undergraduate Honors Capstone Projects
Sharma and de Lima (1992) have proposed a model based on Fixman's theoretical development of charged macromolecules in external fields (1980). There are three types of charges considered: the fixed surface charges that are covalently bonded, the layer of bound counterions, and the diffuse layer (Fixman, 1980, Lyklema, 1983 ). Figure (1) shows these different layers. Other common theories, such as Schurr's only consider the bound counterions and the diffuse layer. Schurr assumes that the diffuse layer ions can exchange with the electrolyte. A consequence of this assumption is the lack of polarization of the diffuse layer. This leads to …
Discussion And Measurement Of Soil Erosion In Iceland, Kimberly Jane Richardson
Discussion And Measurement Of Soil Erosion In Iceland, Kimberly Jane Richardson
Undergraduate Honors Capstone Projects
Soil erosion has occurred since the beginning of time. It is a natural process, but one that has been increasing at an alarming rate. Once soil is eroded--whether it is blown out to sea or washed down a river to sedimentize a lake--it is lost. It is almost impossible to reestablish similar soil components and characteristics in a given system. Since soil and vegetation reestablishment is expensive, the prevention of soil erosion by controlling its causes has become the most cost-effective reclamation effort.
After spending six months in Iceland, I wrote this paper on the unique erosion problems facing that …
