Abstract/Contents:Presents research conducted on managing localized dry spots (LDS) and using wetting agents on the golf course. States that "any sand-based green - or even a push-up green topdressed with sand - will develop localized dry spots (LDS) within 12 to 18 months after construction or renovation. As the name implies LDS occurs sporadically throughout the affected green or fairway...The cause of LDS...is water-repellent soil." Compares "treating hot spots" to "treating the whole green", stating that "treating the entire green vastly improves uniform movement of water and wetting of the soil. However, in some cases, it may be necessary to go back and spot-treat areas that are particularly prone to LDS...Some superintendents have suggested that applying a wetting agent to areas of a green that appear healthy and do not have LDS may, in fact, create other problems. They fear that too much moisture or delayed drying of the root zone will occur." States that "all chemicals should be applied only at label rates. This is a good practice, and it is the law...Another reason for following label rates is the potential for phytotoxicity or discoloration of the turf." Concludes that "wetting agents will continue to be the primary tool used by superintendents in their fight against LDS caused by water-repellent soil. The results of research at the University of Georgia show that applying wetting agents at label rates and applying them to the entire area having water-repellent soil is the best way to ensure succcess with any wetting agent product."
