| Abstract/Contents: | "Positive effects of wetting agents on ameliorating hydrophobic soil conditions and decreasing turfgrass water needs have been investigated extensively in recent years. However, the use of wetting agents on golf fairways is hindered by high application costs. Identifying potential benefits associated with wetting agents applications beyond water conservation purposes (e.g. enhanced N adsorption), could help widespread use of these products among golf superintendents. A study was initiated in June 2020 at the University of Floridas Fort Lauderdale Research and Education Center to investigate the effect of three wetting agents rates (Hydro-Inject® applied at either 6 L ha-1 every 28 days, or 3 L ha-1 every 28 or 14 days tested against an untreated control), and three N fertilization rates (2 g N m-2 month-1 and 4 g N m-2 month-1 through ammonium sulphate 21-0-0, or 25 g N m-2 year-1 through a complete 30-0-10 slow release fertilizer) on 'Celebration' performance through the year. Every 2 weeks plots were assessed for turf visual quality (1 to 9 scale), Normalized Difference Vegetation Index (NDVI), Digital Image Analysis (DIA), and Volumetric Water Content measured with Time Domain Reflectometry (TDR; 9 ratings per plot to access water distribution). In additions, monthly soil samples were collected to test for hydrophobicity by means of Water Droplet Penetration Test (WDPT), and leaves tissues were collected and tested for N content and clipping yield. Preliminary results revealed that, even though Hydro-Inject® application at any rate helped reduced soil hydrophobicity, and improved water penetration in the first centimeters of soil, bermudagrass quality was affected only by N rate, with 4 g N m-2 month-1 of ammonium sulfate and 25 g N m-2 year-1 through slow release fertilizer achieving higher quality. No differences in N adsorption were detected during the first months of the trial with use of Hydro-Inject®." |
