Description
Efficient irrigation of sand-based golf course putting greens is critical for minimizing water waste and maintaining a quality putting surface. The objective of the following study was to determine the minimum irrigation required to produce acceptable turf quality through the use of wetting agent (WA) applications and irrigation controlled by soil moisture sensors (SMS). Four irrigation treatments were controlled by SMS based on critically low soil moisture thresholds (12, 10, 8, and 6%). In addition, WA treatments were applied monthly. Average irrigation applied for the 12% threshold was 2.9, 6.1, and 11.1 times greater than the 10, 8, and 6% thresholds, respectively. However, lower thresholds treated with WA had better turf quality, less localized dry spot formation, and greater soil moisture uniformity than the untreated plots. In conclusion, water use can be reduced significantly without sacrificing turf quality by utilizing wetting agents and controlling irrigation with SMS technology.
