Abstract/Contents:"Utilization of poor quality waters in the urban landscape has the potential of saving large quantities of good quality water for higher priority uses. Bermudagrass in particular is well suited to be irrigated with poorer quality water. We conducted a two year field study to determine the long-term effects of applying shallow saline aquifer water to two turfgrass sports fields. The water (2-4 dSm⁻¹) was applied using cyclic irrigation during peak demand months (May-Oct.). Treatments consisted of cycling saline water through existing irrigation systems. Saline substitution of fresh water was set at 1, 2, 3, or 4 times per 7 irrigation events. Irrigations were applied using an ET feedback system and imposing a leaching fraction of 0.15. Turf color and cover, canopy temperature, leaf water potential, tissue moisture content and stomatal conductance were monitored on a bimonthly basis during the peak demand months. All plots were instrumented with tensiometers and salinity sensors. Soil samples were taken yearly from each plot in a grid fashion and analyzed for soluble salts. Contour maps were developed using geostatistical techniques. Results will be discussed in terms of defining the optimum substitution rate based on maintaining turf quality and baseline salinity values during off irrigation periods below threshold values."
