Halotolerant Rhizosphere Bacteria: Isolation Of Rhizosphere Bacteria From Native Utah Plant Ceanothus Velutinus, Alyssa Nielsen
Halotolerant Rhizosphere Bacteria: Isolation Of Rhizosphere Bacteria From Native Utah Plant Ceanothus Velutinus, Alyssa Nielsen
Fall Student Research Symposium 2021
Increasing incidences of drought forced farmers to use the secondary, degraded water for irrigation. These water sources are rich in salt concentrations. This project has started with the hopes of finding bacteria from the rhizosphere of a native to Utah plant, Ceanothus velutinus, that helps the plant survive the saltier conditions of Utah. The rhizosphere, a layer of soil attached to the roots of a plant, contains microorganisms that may contribute to the plants' abiotic and biotic stress resistance. These microorganisms are known as Plant Growth Promoting Rhizobacteria (PGPR). The roots and rhizosphere samples were collected from Tony Grove in …
Irrigation System Maintenance, Candace Schaible, Kelly Kopp, Jennie Hoover
Irrigation System Maintenance, Candace Schaible, Kelly Kopp, Jennie Hoover
All Current Publications
Irrigation system maintenance is necessary to ensure the most efficient use of the water that is being applied. Efficient irrigation is important because over two-thirds of the total water used in the average Utah home is applied to the landscape. With the natural drought cycles that occur in Utah and the growing population, efficient water use is critical. These maintenance recommendations will help you evaluate your irrigation system before using it each spring and also throughout the growing season.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Over half the land in the US is dedicated to agriculture, with the vast majority of all cropland cultivated in corn, wheat, or soybean. Despite continuing advances in agricultural technologies, and consistent yield growth over the twentieth century, research suggests that environmental change is already impacting agricultural yield and future changes are sure to exacerbate challenges to agricultural production. It follows that the future of US agriculture depends on the evolution of the changing climate, the relationship between crop yields and the environment, on-farm management and adaptations, the ecosystems that support agriculture, the political and economic incentives that shape what …

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 …
Comparison Of Onion Irrigation Methods: Furrow Versus Drip, Chad Withers
Comparison Of Onion Irrigation Methods: Furrow Versus Drip, Chad Withers
Student Research Symposium
The State of Utah is funding agricultural water optimization studies to determine how agricultural water depletion can be decreased while maintaining or improving yields. Conversion from surface irrigation to drip irrigation is being investigated as a method to decrease consumptive use. Some Utah onion producers are converting from furrow irrigation to drip irrigation to decrease water and fertilizer use and improve profits. This study will compare the consumptive use and yield of three drip irrigated onion fields to three furrow irrigated onion fields. To conduct the study arrays of soil moisture sensors at various depths were placed in drip and …
Irrigation Management In High Tunnels, Dan Drost, Brent Black, Melanie Stock
Irrigation Management In High Tunnels, Dan Drost, Brent Black, Melanie Stock
All Current Publications
High tunnels provide season extension for various high-value horticulture crops in a diverse range of climates. These large, plastic-covered structures modify the environmental conditions of the covered area. Temperature management is commonly the focus when growing in high tunnels as this may be the key factor limiting plant growth during much of the year. While high tunnel temperature management is important, growers also need to address water management to ensure plants are not water-stressed. Common mistakes are underestimating water needs, which stresses plants or creates conditions favoring plant diseases and nutrient leaching from overwatering. Knowing when to irrigate and how …
