Abstract/Contents:"Most turfgrass research has shown that irrigating deeply and infrequently is best for overall turfgrass health. However in the arid West, a region of warm to hot summers and low humidity, frequent irrigations may result in water savings and no loss in turfgrass quality. We studied four turfgrasses (Kentucky bluegrass, tall fescue, prairie junegrass, and buffalograss) at three irrigation frequencies, every 2, 4, or 6 days 70% of ETo replacement. Overall, the turfgrass quality of the 2-day interval was better than the 4- and 6-day intervals, however, differences varied from year-to-year. The 2-day interval provided a very consistent level of soil moisture over time. Soil and thatch layer temperatures in the 6-day interval plots experienced increasing temperatures each day, prior to an irrigation event compared to more consistent temperatures in the 2-day treatment. However, 2-day interval plots were consistently warmer in many time periods. Although the quality was higher in the 2-day plots, the turf is more vulnerable to drought stress in the event of irrigation delays. A schedule of infrequent and deep watering, possibly on a 6-day schedule combined with a light irrigation daily or every other day maybe a good compromise."
