What About Wetting Agents?

Douglas Karcher, Ph.D.

Localized dry spots on sand-based putting greens are common throughout the world. Wetting agents are an effective treatment for localized dry spots, but superintendents often question whether their use will result in greens that are either too wet or dry. Doug Karcher, Ph.D., covers the cause of localized dry spots, how wetting agents work to overcome water repellent root zones, and how soil moisture content is affected following wetting agent application. You’ll get tips for effective and efficient use that will help make the most of your dollars spent for these important inputs.
