There have been many studies conducted on the benefits of rolling over the years. The research is very clear that rollers increase the speed of the green. This is the main and reason must superintendents roll greens. What is interesting is through this research there is a noticeable decrease in Dollar Spot on rolled greens. One reason this may be true is that rolling will remove the dew from the surface. Dew is high in sugars and this can be a catalyst for the development of the Dollar Spot fungus.
Most of the research show that rolling does not adversely compact the green but will greatly smooth the surface. I make use of this after spiking the greens. We roll each green right after spiking and there is very little surface disruption after the green has been rolled. Rolling greens will increase the speed approximately 8 to 12 inches after the green has been rolled. The effects of the increase in speed will last about one day after the second day there will be an increase of approximately 6 inches compared to a check plot. The research shows that rolling every other day in conjunction with mowing will maintain faster green speeds, more consistent green speeds, and smoother greens. There is a fine line, rolling more then 4-5 days per week will decrease turf quality over time.
Putting this all together. I will make use of our rollers as another tool to achieve smooth , consistent green speeds thorough out the year. I roll the greens approximately 3-4 days per week depending on the time of the year and condition of the turf.
Thanks, next up will be the top dresser
