| Abstract/Contents: | "As golf course irrigation water quality continues to decline, sand-capping of golf course fairways is increasing. A 3-year USGA-funded Texas A&M study evaluated sand-capping depth by subsoil texture influences on Tifway bermudagrass fairway quality/performance. Sand capping depths of 0", 2, 4, and 8" were evaluated atop both clay and loam subsoils. Based on prior analysis of the sand used and traditional water release curve measurements, an 'optimal' capping depth of 8" was recommended to achieve a balance of air to water filled porosity in the root zone. At the conclusion of the study the 8" depth was found to result in overly dry surface conditions, periodic decline in quality, and hydrophobic conditions in the thatch layer. The 'sub-optimal' 0, 2, and 4" sand-caps all outperformed the 8" cap for all measured parameters. However, it should be noted that changes in the system, including accumulation of organic matter over time may alter these findings. Due to the high Na (~300 ppm) irrigation water used in the study, rapidly increasing subsoil SAR was also observed and should not be overlooked. Collectively, the findings suggest that surface organic matter management, wetting agent applications, and periodic deep cultivation practices combined with high rates of soluble calcium to prevent sealing of underlying subsoil may all be necessary for achieving optimal long-term performance of sand-capped fairways. The objectives of this study are to evaluate long-term (years 4-6) changes in turf performance, soil physical properties, and cultural management requirements of sand-capped fairway plots. A split-split-plot design is being used to assess low to high-input management intensities involving various combinations of wetting agents, gypsum applications, and deep cultivation practices to maintain sand-cap and subsoil physical integrity. Results indicate that traditional surface gypsum application methods and rates may need to be modified to mitigate sodium accumulations at the sand/subsoil interface." |
