Putting green speed is a popular topic among golfers all over the world. The Stimpmeter and Pelzmeter are two devices commonly used to measure putting green speed. However, it is unclear how similar these meters compare for measuring putting green speed. Increasing putting green speed without decreasing turfgrass quality is a difficult task for golf course superintendents. However, rolling putting greens may allow turf managers to decrease mowing frequency or increase mowing height without losing green speed. This would be particularly beneficial in minimizing summer stress on creeping bentgrass (Agrostis stolonifera L.) putting greens in the transition zone. Because mowing heights have gradually decreased since the release of the Stimpmeter in 1977, it is important to identify a management practice like greens rolling that can produce acceptable green speeds, without decreasing the quality of the putting surface. There are also circumstances that require golf course superintendents to increase putting green speeds by all means necessary in short periods of time, but this can be detrimental to the overall quality of the playing surface. Therefore, the objectives of this research were to: (1) compare the measurement variability between the Pelzmeter and the Stimpmeter when measuring putting green speed and to determine if they provide similar results on the same putting surface, (2) determine the effects of mowing height, mowing frequency and rolling frequency on green speed, turf quality, and water infiltration on a sand-based putting green, and (3) determine the impact that rolling the putting surface more often than six times per week has on turf quality or water infiltration. There was a strong linear relationship (R2 = 0.90) between the Pelzmeter and the Stimpmeter when measuring putting green speed on the same turf. Rolling treatments increased ball roll distance compared to non-rolled control plots. All plots remained above minimum acceptable quality throughout all three studies. Infiltration rates decreased slightly as rolling frequency was increased, but still remained acceptable. The results of this study indicate that with rolling, golf course superintendents can mow less frequently or at a higher height to minimize summer stress while maintaining desired green speeds. Finally, when rolling more than six times per week in 2008, plots rolled eight times per day produced significantly faster green speeds compared to plots rolled two and four times per day. Plots rolled two times per day consistently had the highest quality, though there were some small differences in water infiltration. All rolling treatments remained above the acceptable infiltration rate for a sand-based putting green. In 2009, when averaged over all evaluation dates, with the exception of rolling once per day, as rolling frequency increased, ball roll distance also increased significantly. A rolling frequency of two times per day maximized the benefit in ball roll distance achieved through the added practice of greens rolling. Turf quality and water infiltration decreased as rolling frequency increased and surface hardness increased as rolling frequency increased. Therefore, golf course superintendents can implement high-frequency rolling programs on their putting greens for short periods of time without decreasing overall turf quality or water infiltration.
