| Abstract/Contents: | "Capping of degraded golf course fairways with a layer of sand to promote better turfgrass health, performance, and playability is becoming a common practice where irrigation water is of poor quality, usually high in sodium. Benefits of sand-capping include improved drainage and increased infiltration rates, greater rooting depth, improved traffic tolerance and playing conditions, alleviated compaction, enhanced ability to flush salts, and improved soil structure. However, over time, unique management challenges may arise, including organic matter accumulation, surface hydrophobicity, and subsoil permeability issues, especially where irrigation water contains elevated levels of sodium. The objectives of this 3-year project are to evaluate the effects of wetting agent applications for reducing surface hydrophobicity, and of gypsum for enhancing subsoil permeability by reducing the sodium accumulation, on performance of 'Tifway' bermudagrass on sand-capped soil. A split-split-plot design is being used to evaluate the effects of combinations of wetting agent (Oars PS monthly 0 vs. 0.002 L m-2) and gypsum application programs [Verdecal G at 0, 48 (monthly), and 480 g m-2 (one annual application)] across four capping depths to maintain sand-cap and subsoil physical integrity in a 5-year old sand-capped fairway. Results to date indicate that traditional gypsum application methods involving monthly applications at lower rates (48 g m-2) are not as effective as a single early-spring application at higher rates (480 g m-2) for alleviating subsoil sodium accumulation. The data also indicate that wetting agent applications are critical for managing surface hydrophobicity in deeper (20 cm) capping depth plots, but not for shallower capping depths (5-10 cm)." |
