| Abstract/Contents: | "Foliar nitrogen (N) fertilization continues to gain popularity with golf course superintendents, especially in regard to putting green nutrition. However, little is currently known about the efficiency of this practice in the field or the significance of the possible N loss mechanisms associated with foliar applications. This project was conducted to document the extent of ammonia volatilization from turfgrasses managed as putting greens, following the application of foliar N using area (46-0-0), over a 24 h period. Two different foliar fertilizer rates (0.10 and 0.25 lb N / 1000ft2) were applied once monthly (May through September) to 'Penn A-1' creeping bentgrass and 'Tifeagle' ultradwarf bermudagrass established putting greens. Ammonia volatilization over a 24 h period was measured via boric acid trapping. Month of year and N rate both had a significant effect on the amount of N volatilized from the turfgrass canopy. At each sampling date and on both species, measurement of ammonia volatilization was consistently small with a maximum observed loss of 7%." |
