Hybrid Bermudagrass And Kentucky Bluegrass Response Under Deficit Irrigation In A Semi-Arid, Cool Season Climate, Hanna R. Burgin
Hybrid Bermudagrass And Kentucky Bluegrass Response Under Deficit Irrigation In A Semi-Arid, Cool Season Climate, Hanna R. Burgin
Theses and Dissertations
As average global temperatures rise, cool-season C3 turfgrasses, such as the most commonly grown Kentucky bluegrass (Poa pratensis L.; KBG), struggle to tolerate extreme summer heat and increase their water consumption. Hybrid Bermudagrass (Cynodon dactylon [L.] Pers. × Cynodon transvaalensis Burtt Davy; HBG) is a warm-season C4 grass that may be increasingly suited for northern ecosystems traditionally classified as transition or cool-season climate zones. Glasshouse and field studies were conducted to compare HBG and KBG water use. The objective of the glasshouse study was to evaluate plant health and growth for two HBG cultivars (‘DT-1’ and ‘NorthBridge’) compared to a …
Remote Sensing Approaches To Improve Water And Nitrogen Management Of Kentucky Bluegrass (Poa Pratensis), Austin Hopkins, Dr. Neil C. Hansen
Remote Sensing Approaches To Improve Water And Nitrogen Management Of Kentucky Bluegrass (Poa Pratensis), Austin Hopkins, Dr. Neil C. Hansen
Journal of Undergraduate Research
This project identifies remote sensing practices to conserve water by optimizing nitrogen (N) fertilization and irrigation strategies. Turfgrass is the most irrigated crop by area (163,800 km2 ), accounting for 1.9% of the continental U.S. This causes negative environmental impacts and puts the future of irrigated turfgrass in question due to increasing water scarcity, especially in the western U.S. More information is needed on how to irrigate in droughts and water limited areas as turf provides significant benefits in our environment such as aesthetics, cooling effects, carbon sequestration, and preventing soil erosion.
Nitrogen And Water Interactions In Drought Stressed Kentucky Bluegrass Conserving Our Vital Resource, Kerri Russell, Bryan G. Hopkins
Nitrogen And Water Interactions In Drought Stressed Kentucky Bluegrass Conserving Our Vital Resource, Kerri Russell, Bryan G. Hopkins
Journal of Undergraduate Research
Turfgrass is the irrigated crop of greatest acreage in the United States. As urban and suburban developments are growing at an unprecedented rate, the demand for turfgrass is in high demand. Its ecosystem services are valuable and include groundwater protection, erosion control, soil health, and air purification. It also provides high utility to residential and public lands. Despite its environmental benefits, turfgrass has been brought under scrutiny due to natural resource consumption and pollution, particularly in arid and semi-arid regions of the western US. Turfgrass requires a significant amount of irrigation water, a resource that is scarce in the arid …
Polymer Coated Urea In Kentucky Bluegrass, Jessica Chelise Buss
Polymer Coated Urea In Kentucky Bluegrass, Jessica Chelise Buss
Theses and Dissertations
Nitrogen (N) is the most commonly over-applied nutrient in urban environments because of the large visual and growth increases. This over-application has led to an increase in the loss of N gas in the forms of ammonia and nitrous oxide, as well as an increase in nitrate leaching to surface and groundwater. Furthermore, excess N results in increased maintenance costs and landfill volume due to increased shoot growth from mowed clipping removal. Polymer coated urea (PCU) has proven to be an excellent source to these losses of N to the environment, but rate and timing parameters need study. A two-year …
