Nutrient Management Of Cannabis In Controlled Environments, Julie A. Hershkowitz
All Graduate Theses and Dissertations, Fall 2023 to Present
Cannabis has been cultivated for millennia as a multipurpose crop for food, fiber, and medicine. Secondary metabolites called cannabinoids, including cannabidiol (CBD) and the psychoactive Δ-9 tetrahydrocannabinol (Δ-9 THC), are responsible for the medicinal properties of cannabis. The intoxicating nature of THC resulted in legislation prohibiting the possession and production of cannabis within the United States during the 20th century. As a result, research programs on cannabis production were halted at most institutions. In recent years, cannabis production has become widespread within the US as a result of increasing legalization. However, modern cannabis production nutrient management programs often include …

Processes For Improved Variable Rate Irrigation And Nitrogen Within Potato-Wheat-Wheat Cropping Systems, Elisa A. Flint
Processes For Improved Variable Rate Irrigation And Nitrogen Within Potato-Wheat-Wheat Cropping Systems, Elisa A. Flint
All Graduate Theses and Dissertations, Fall 2023 to Present
Proper irrigation and nutrient management are vital for optimal crop production within agricultural fields. Improving irrigation and nutrient application through precision agriculture is necessary to conserve the limited resources available, while improving yield and quality of crops produced through such a system. Variable rate irrigation (VRI) and variable rate nitrogen are systems used to apply water and nitrogen more precisely to agricultural fields to reduce runoff, deep percolation, leaching, and other negative impacts of over application, while providing the optimal rates to produce maximum yields. However, the processes to utilize these systems have proven to be more difficult than expected, …

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 …

Contrasting Nitrogen Sources Impact Nitrogen Use Efficiency And Soil Health Under Silage Corn Production In A Semi-Arid Environment, Phearen Kit Miller
All Graduate Theses and Dissertations, Fall 2023 to Present
Silage corn production challenges sustainable intensification and soil health in semi-arid environments because the entire aboveground biomass is harvested and removed from the field. An irrigated silage corn field study was conducted over a decade comparing nitrogen fertility sources using a complete randomized block design with four treatments: control with no nitrogen fertilizer (control), low ammonium sulfate at 112 kg N ha−1 (AS100), high ammonium sulfate at 224 kg N ha−1 (AS200), and steer manure compost at 224 kg total N ha−1 (compost). Research focused on the impact of these contrasting nitrogen sources on silage corn production, …
Sustainable Fertilizer Management Practices For Container Nursery Production, Saroj Burlakoti
Sustainable Fertilizer Management Practices For Container Nursery Production, Saroj Burlakoti
All Graduate Theses and Dissertations, Fall 2023 to Present
Growing nursery plants in containers requires a timely supply of mineral nutrients for optimum growth. However, there is a misconception among growers that the application of higher doses of fertilizers hastens plant growth; instead, it can lead to runoff and leaching loss of nutrients. Reducing fertilizer application while sustaining healthy plants can not only negate environmental consequences but also save fertilizer costs. For example, two ground covers, Lysimachia nummularia (creeping jenny, moneywort) and Vinca minor 'Bowles' (periwinkle), can be grown for three months by applying 6 mg/L of phosphorus (P) as reduction of P to single application of 6 mg/L …

Utah Hydroponic Solutions, Bruce Bugbee, Noah Langenfeld
Nutrients
The Utah Hydroponic solutions for monocots and dicots have been developed and refined using mass balance principles coupled with tissue analysis from studies in 25-cm deep, continuously aerated, liquid hydroponics where there is no absorption or desorption with media.
These solutions provide guidelines for irrigation of soilless substrates, but adjustments may need to be made to account for the significant cation exchange capacity and thus nutrient absorption and desorption with the substrates.
These recipes were developed for greenhouse conditions with ambient CO2 and about 40% humidity. This results in a water use efficiency of about 3 grams per Liter. …

Seeds are used in many aspects of plant research as well as in applications such as ecosystem restoration. However, not all seeds are living (i.e., viable). To successfully work with seeds, it is essential to know how many seeds are viable. Seed viability can be assessed through a few different avenues, such as a basic cut test (i.e., is the embryo fully developed), germination assays, x-ray imaging, or the most common—a tetrazolium (TZ) test. This document focuses on best practices for TZ testing for a wide array of common wetland species that have been the focus of research and restoration …

Aspen Bibliography
Oystershell scale (OSS; Lepidosaphes ulmi L.) is an invasive insect that threatens sustainability of aspen (Populus tremuloides Michx.) in the southwestern United States. OSS invasions have created challenges for land managers tasked with maintaining healthy aspen ecosystems for the ecological, economic, and aesthetic benefits they provide. Active management is required to suppress OSS populations and mitigate damage to aspen ecosystems, but before management strategies can be implemented, critical knowledge gaps about OSS biology and ecology must be filled. This study sought to fill these gaps by addressing 3 questions: (i) What is the short-term rate of aspen mortality in …

Aspen Bibliography
Quaking aspen (Populus tremuloides Michx.) stands throughout the western United States provide valuable ecosystem services but can be lost via succession from aspen to conifer. Forest managers are cutting conifers, but disposal of cut wood can be challenging in remote or sensitive areas. Piling and burning is being tested within aspen stands but ecosystem responses to this treatment are understudied. We assessed aspen tree mortality, tree regeneration, and understory vegetation after forest restoration thinning followed by pile burning in seven aspen-conifer stands around Lake Tahoe, California and Nevada, USA. Pile burning was conducted after cut wood had dried (1.5–7.5 …
