Abstract/Contents:"Ammonia (NH3) volatilization of folialry-applied nitrogen (N) fertilizer is detrimental to both the environment and the original agronomic objective. While several best management practices are shown to reduce NH3 volatilization from urea-based fertilizers, their employment is precluded by circumstance not uncommon to golf course putting green management. Our research objective is to quantify how foliar application of commercially available urea-N fertilizers, in combination with petroleum-derived spray oil (PDSO), influences canopy quality, urea-N recovery, and 0- to 24-hour NH3 loss from putting greens. 'Penn G2' creeping bentgrass plots were treated by Civitas Turf DefenseTM (Intelligro, LLC) at a 27 L ha-1 rate, and/or 7.32 kg ha-1 foliar-N as urea, urea/NH4NO3 (UAN), or methylol/methylene urea solution in 611 L ha-1 every 14 days. Closed-flux chambers were employed immediately following foliar applications in July and September to measure NH3 volatilization. A passive multispectral radiometer was used to collect semi-weekly reflectance signatures for computation of canopy density and color indices. Monthly clipping yields were weighed to 0.1-mg resolution and analyzed for total N content. Clipping yields collected in June & July 2019 showed improved nitrogen recovery from N fertilizer-PDSO combinations, relative to N fertilizer applied without. Ammonia volatilization and canopy quality data collected over the 2019 season will be presented."
