Nutrient Uptake And Water Quality In Great Salt Lake Wetland Impoundments, Rachel L. Buck
Nutrient Uptake And Water Quality In Great Salt Lake Wetland Impoundments, Rachel L. Buck
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Great Salt Lake (GSL) is the largest inland body of water on the Pacific flyway, a major pathway for migratory birds in the Americas that extends from Alaska to Patagonia. The lake is surrounded by approximately 360,000 acres of wetlands, providing critical food, shelter, cover, nesting areas, and protection to between 4–6 million birds that visit each year. Impounded wetlands were created as part of the GSL ecosystem to support waterfowl habitat. These large, shallow, submergent wetlands are diked to control water levels to sustain aquatic plants which are an important food source. Besides providing critical habitat, these impoundments …
4r Nitrogen And Water Optimization Combinations For Intermountain West Field Crops, Tina Sullivan
4r Nitrogen And Water Optimization Combinations For Intermountain West Field Crops, Tina Sullivan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The concept of 4R (right source, rate, placement, and timing) management needs little introduction due to the surplus of nutrient studies in the literature for most cultivated crops. However, few studies have looked at these practices in the Intermountain West with nitrogen use, and fewer looked at 4R irrigation management. A survey was conducted to explore the interactions of nitrogen and irrigation management, test sensitivity to supply and price changes of nitrogen and irrigation for Utah and Idaho growers of small grains, corn, and potatoes, and determine the current adoption of precision agriculture options and identify the opportunities to improve. …
