Effects Of Wi-Fi-Enabled Smart Irrigation Controllers On Water Use And Plant Health Of Residential Landscapes In The Intermountain West, Shane R. Evans Dec 2020

Effects Of Wi-Fi-Enabled Smart Irrigation Controllers On Water Use And Plant Health Of Residential Landscapes In The Intermountain West, Shane R. Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Residential and commercial landscapes provide home and business owners with several benefits. These benefits range from improved air quality and flood control to the reduction of noise and breakdown of organic chemicals. However, these landscapes are routinely overwatered which can lead to plant disease, nutrient pollution, and large amounts of water being wasted. Utah State University, in conjunction with the Center for Water Efficient Landscaping (CWEL), the Utah Division of Natural Resources and Weber Basin Water Conservancy District, conducted an experiment to determine if Wi-Fi-enabled smart irrigation controllers conserve water as compared to average residential irrigation amounts and manually programmed …


Evaluation Of Biological Thatch Control On Golf Greens, Joshua Randall Weaver May 2020

Evaluation Of Biological Thatch Control On Golf Greens, Joshua Randall Weaver

All Dissertations

Thatch is a layer of living and dead plant material (stems and roots) between turfgrass leaf tissue and the soil surface and if excessive, it can decrease playability of turf surfaces, increase mower scalping and disease pressure, reduce pesticide efficacy and water infiltration, plus harbor insects. In golf greens, mechanical, thus, disruptive practices such as vertical mowing, core cultivation, grooming, and topdressing are traditional agronomic methods for managing thatch/organic matter. Greenhouse and field experiments were conducted for two years to evaluate two commercial biostimulant products, Worm Power and Earth MAX, and their impact on thatch and rooting depth. Earth MAX …


Greening Golf: Grass, Agriculture, And Pinehurst In The Sandhills, Matthew Himel May 2020

Greening Golf: Grass, Agriculture, And Pinehurst In The Sandhills, Matthew Himel

Theses and Dissertations

“Greening Golf” explores how and why many golfers and tourists have come to see Pinehurst, and thousands of courses like it, as naturally-occurring landscapes and to what degree they should. It examines the tightly bound environmental and cultural history of the Sandhills to explain both the rise of the resort within a very particular environmental context in the post-Civil War rural South, and the surprising ways that golf came to have intense influence over it. Rather than viewing the growth of the sport as the result of cultural and environmental changes in American history, this dissertation treats golf as a …
