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 …
Compost And Cover Crop Effects In Dryland Organic Wheat, Michael D. Deakin
Compost And Cover Crop Effects In Dryland Organic Wheat, Michael D. Deakin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Producers of dryland organic wheat (Triticum aestivum L.) in the western USA struggle to maintain adequate soil fertility due to the high cost of organic fertilizers and concerns over moisture use of cover crops. Low soil fertility results in decreased wheat yield and quality, and increased year-to-year variability in yield and quality based on weather. This study was conducted to measure the effects of, and interactions between, cover crop mixes and a one-time compost application on soil health and winter wheat yield and quality. The study was located on three adjacent certified organic wheat farms near Snowville, UT, each …
