Abstract/Contents:Golf course superintendents use 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. Increased rootzone oxygen may also increase organic matter breakdown, facilitating thatch reduction. This research aims to compare the effects of long-term irrigation with nanobubble oxygenated water sources and untreated water sources on bentgrass putting green plant health characteristics as well as soil oxygen and organic matter content. Treatments include super-oxygenated potable water and irrigation pond water, containing more than 15 mg L-1 dissolved oxygen, created using a nanobubble generator (Nano Bubble Technologies, Sydney, NSW, AU) as well as untreated potable and irrigation pond water. Irrigation treatments are applied every other day to replace 100% net evapotranspiration. Soil oxygen is recorded hourly at a depth of 17 cm and 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 monthly. Root samples are collected monthly and analyzed for root length, size, and mass using WinRhizo scanning image analysis. Total organic matter content (TOMC) for each treatment is determined monthly by weight loss on ignition. No significant differences between treatments were detected for soil oxygen and organic matter content, green cover, DGCI, clipping yield or root growth characteristics.
