Comparison Of Private And Public Lab Fertilizer Recommendation Impacts On Field Crop Production And Soil Test Results, Megan Baker
Comparison Of Private And Public Lab Fertilizer Recommendation Impacts On Field Crop Production And Soil Test Results, Megan Baker
All Graduate Theses and Dissertations, Fall 2023 to Present
There are many sources that farmers utilize to determine fertilizer needs for crops such as private and public labs, crop advisors, and fertilizer dealers. In many cases, these sources provide recommendations for a specific crop that can vary greatly, which can lead to large differences in cost. An experiment was established in 2021 with 12 sites across the state of Utah in alfalfa, small grains, and corn to test and compare fertilizer recommendations from five labs. The recommendations tested were from two public labs (Utah State University and the University of Idaho) and three commercial labs located in the Western …

Innovative Water Management Using Advanced Irrigation Systems And Biochar, Jonathan A. Holt
Innovative Water Management Using Advanced Irrigation Systems And Biochar, Jonathan A. Holt
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two approaches to water optimization in agriculture are to increase soil water retention and improve the efficiency of irrigation. A soil amendment that has received attention for its ability to increase soil water retention is biochar, the remaining biomass after high C materials have been pyrolyzed (burned with limited oxygen and heat). Two studies were conducted at a total of 10 site-years in Utah from 2018 to 2020 to evaluate how wood biochar influences the productivity and crop quality of irrigated alfalfa (Medicago Sativa L.), corn (Zea mays L.), and wheat (Triticum L.), along with soil water tension. One study …
Effects Of Irrigation Technology And Rate On Hemp Production, Tina Sullivan
Effects Of Irrigation Technology And Rate On Hemp Production, Tina Sullivan
Student Research Symposium
The industrial hemp industry is rapidly emerging in Utah - nearly 1,200 acres were permitted in the state in 2019, and new growers registered for 2020. Many questions remain on optimal production practices for this new and potentially high-value crop. Research throughout the United States is limited as more and more states issue hemp, smokable flower, and medical marijuana licenses. One for the first Utah outdoor research sites was set up for the 2020 growing season and will be repeated in 2021. Trials on fertilizer, variety, and irrigation and rate were tested in different spans (sections) of a lateral irrigation …
The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne
The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne
Human–Wildlife Interactions
The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …

Non-Methane Hydrocarbon Source Apportionment And Btex Risk Assessment Of Winter 2015 In Roosevelt, Utah, Jerimiah Lamb
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Non-Methane Hydrocarbons (NMHC) monitored in Roosevelt Utah including Benzene, Toluene, Ethylbenzene and Xylene (collectively known as BTEX) are associated with deleterious effects including cancer. This study was designed to assess the origin and effect of the toxicants and addressed two points: 1) Source identification using the USEPA’s Positive Matrix Factorization (PMF) and NOAA’s Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model and 2) A human health risk assessment based on ambient concentrations of BTEX collected at the Roosevelt site. Model fit indicated that the primary contributor to total NMHCs was local oil and gas operations and was supported by previous …
Assessing Phosphorus Sources With A Gis-Based Phosphorus Risk Index In A Mixed-Use, Montane Watershed, Josiah A. Johns
Assessing Phosphorus Sources With A Gis-Based Phosphorus Risk Index In A Mixed-Use, Montane Watershed, Josiah A. Johns
Theses and Dissertations
Elevated phosphorus (P) loading of freshwater lakes and reservoirs often results in poor water quality and negative ecological effects. Critical source areas (CSA) of P in the watershed can be difficult to identify and control. A useful concept for identification of a CSA is the P risk index (P Index) that evaluates the P risk associated with distinct source and transport pathways. The objectives of this study were to create a GIS model that adapts the Minnesota (MN) P Index for use at the watershed scale in a mixed-use, mountain environment, and to evaluate its effectiveness relative to field-based assessment. …
Assessing Phosphorus Sources With Synoptic Sampling In The Surface Waters Of A Mixed-Use, Montane Watershed, Austin Willis Pearce
Assessing Phosphorus Sources With Synoptic Sampling In The Surface Waters Of A Mixed-Use, Montane Watershed, Austin Willis Pearce
Theses and Dissertations
Few elements in surface waters are monitored as closely as phosphorus (P) due to its role in the eutrophication and degradation of surface waters. Limiting P mobilization from source areas is, therefore, a central goal of water quality protection plans. But the work of locating sources in mixed-use watersheds is challenged by the spatial and temporal variability of critical source areas (CSAs) of P. Synoptic sampling is a proven method for capturing the spatial variation of water quality parameters in surface waters, though it's not often used to track temporal dynamics across the same study area. Phosphorus fractionation is an …
Validation Of Tissue Nutrient Status For Tart Cherry (Prunus Cerasus) And Peach (Prunus Persica) In Utah, Emily Tsai
Validation Of Tissue Nutrient Status For Tart Cherry (Prunus Cerasus) And Peach (Prunus Persica) In Utah, Emily Tsai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Fruit tree nutrition requirements change during the growing season as buds form, shoots grow, fruit sets, and internal reserves are filled. Nutrient concentrations in plant tissues are directly correlated with the nutritional status and productivity of fruit trees. Plant tissue testing is used to effectively and accurately determine the nutritional status of perennial plants. Tissue test analyses were performed on tart cherry (Prunus cerasus) and peach (Prunus persica) leaves to validate tissue sufficiency levels used in Utah and to determine optimal timing of tissue sampling for prediction of harvest nutrient status, focusing on phosphorus (P), potassium …

Mechanical Mastication Of Utah Juniper Encroaching Sagebrush Steppe Increases Inorganic Soil N, Kert R. Young, Bruce A. Roundy, Dennis L. Eggett
Mechanical Mastication Of Utah Juniper Encroaching Sagebrush Steppe Increases Inorganic Soil N, Kert R. Young, Bruce A. Roundy, Dennis L. Eggett
Articles
Juniper (Juniperus spp.) has encroached on millions of hectares of sagebrush (Artemisia spp.) steppe. Juniper mechanical mastication increases cover of understory species but could increase resource availability and subsequently invasive plant species. We quantified the effects of juniper mastication on soil resource availability by comparing total C, total N, C : N ratio, Olsen extractable P, sulfate S, and pH using soil samples and inorganic N (NO3-+NH4+) using ion exchange membranes. We compared resource availability in paired masticated and untreated areas in three juniper-dominated sagebrush and bunchgrass ecosystems in the Utah portion …

Ungulate Damage To Safflower In San Juan County, Utah, Michael J. Haney
Ungulate Damage To Safflower In San Juan County, Utah, Michael J. Haney
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In Utah, farmers are concerned that ungulates are damaging safflower (Carthamus tinctorius) fields. I examined elk (Cervus elaphus) and mule deer (Odocoileus hemionus) damage to safflower production in San Juan County, Utah during 2009 and 2010. Data on damaged safflower plants were collected within 28 fields, totaling 1,581 ha (13 fields totaling 963 ha during 2009; 15 fields totaling 618 ha during 2010). I compared 3 methods to assess losses: ungulate-proof exclosures, adjacent plant compensation method, and counting the number of damaged plants in 50-m transects (safflower count method). Exclosures were of limited use …

The Transfer Of Agricultural Water To Municipal And Industrial Usages, Dallin Paul Stephens
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The water that is available for beneficial use in Utah is quickly approaching full appropriation; water that has been claimed is nearing the amount that is available for use. The Division of Water Resources of the State of Utah has organized a three-part plan to "Plan, Conserve, Develop and Protect Utah's Water Resources." One of these three elements has a focus to "provide comprehensive water planning." Such planning is best achieved when current and accurate data on the uses of the state's water are available.
The primary purpose of this thesis was to provide an evaluation, from data collected on …

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 …
