Comparative Study of Recycled Water Irrigation and Fairway Turf
Abstract
The quantity and quality of irrigation water are limiting factors in maintaining high-quality turf grasses for landscapes and golf courses in Southern California. The incorporation of a surfactant (wetting agent) in the irrigation protocol is being encouraged in order to conserve irrigation water. Wetting agents are organic polymers, which can be injected into the irrigation lines in order to reduce water usage on landscapes and golf courses. Wetting agents help retain water in the soil profile for a longer period of time, and hence can increase the time in between irrigation cycles. This research project evaluated three different surfactants and their interaction with two different water sources.
