| Abstract/Contents: | "Golf course superintendents often implement various methods of increasing soil oxygen in putting green rootzones such as, core aerification, solid-tine aerification, and sand topdressing. Aerification is time intensive, disrupts the putting surface, and is unpopular with golfers. Another method of delivering oxygen to the soil could be through nanobubble oxygenated water. Nanobubbles are sub-micron, stable cavities of gas typically between 200-700 nm. The properties of nanobubbles allow for high gas dissolution rates resulting in super-saturation of oxygen in water. Nanobubble technology may promote increased rooting of creeping bentgrass (Agrostis stolonifera) putting greens during the stressful summer months and lead to a healthier, more vigorous playing surface. This research aims to compare the effects of long-term irrigation with nanobubble oxygenated water and regular irrigation water on bentgrass putting green plant health characteristics as well as soil oxygen content. Treatments include super-oxygenated water, containing more than 15 mg L-1 dissolved oxygen, created using a nanobubble generator (Nano Bubble Technologies, Sydney, NSW, AU) as well as an untreated control consisting of standard potable irrigation water. Irrigation treatments are applied every other day to replace 140% net evapotranspiration. Soil oxygen is recorded hourly at a depth of 17 cm and reported as the partial pressure of oxygen (kPa) using 8 Apogee SO-110 soil oxygen sensors (Apogee Instruments, Logan UT). Turf color and quality are evaluated weekly using digital image analysis. Clipping yields are collected, dried and weighed, every second week. Root samples are collected monthly and analyzed for root length, size, and mass using WinRhizo scanning image analysis. Nanobubble oxygenated water increased partial pressure of soil oxygen at a 17 cm depth compared to standard irrigation water on multiple dates throughout the summer. Root growth parameters and clipping dry weight did not differ between nanobubble oxygenated water and standard irrigation water." |
