In 2010 we began regularly rolling our greens at WR. We are currently rolling 3-5 times per week and we have seen a steady improvement in playability, particularly roll out and smoothness. The slight compaction that results is possibly beneficial as it maintains more moisture in the surface 2". Our use of wetting agents every month helps even out the moisture distribution through the profile and the result has been more consistent moisture levels from green to green. The following video highlights Dr Frank Rossi's take on rolling and he, along with Dr Nikolai from MSU are considered the authorities on rolling research. Enjoy.
