| 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 (NH3) volatilization from a creeping bentgrass putting green following the application of various foliar N sources commonly used by local golf course superintendents. Regardless of label rate indicated on each liquid or soluble foliar fertilizer source, each product was mixed with deionized water and applied at a common rate of 0.25 lb N/1000ft2. Applications were made once per year in late August/early September of 2007 and 2008 to a 'Penn G-2' creeping bentgrass putting green. Ammonia volatilization over a 24 h period was measured via boric acid trapping. Percentages of N applied and lost via NH3 volatilization, when averaged across years, were less than one percent for each source used in this study. Attempts were made to utilize environmental conditions that would exacerbate NH3 volatilization potential. Therefore, the results from our field trial suggest that, regardless of fertilizer source or chemical form, foliar N application (typical N rates) to putting green turf can be made without concern for substantial N loss via volatilization." |
