Putting green firmness is a key playability factor in the game of golf. Greens that are too soft reward poorly struck approach shots, while a green that is too hard may result in unanticipated ball movement. The intent of this research was to develop recommendations for golf course superintendents in regards to managing surface firmness. Previous research found that greater soil moisture content results in a softer surface on most putting green root zone types. The level of compaction and organic matter content may also influence surface firmness. The study was a 3 x 2 x 3 factorial, setup as a split block design over multiple locations/putting greens with different levels of irrigation applied at different locations. Each block had three levels of compaction and half of each block was dethatched. All three putting green root zones were brought to relatively high water content, allowed to dry down to a relatively low water content, and then the different irrigation application rates were initiated. Soil moisture content, surface firmness, turfgrass quality, and green speed were measured throughout the trial. High soil water content resulted in softer surfaces as expected. Plots that were rolled daily typically had firmer surfaces than other compaction level plots. Dethatching did not significantly lower organic matter content or increase water infiltration rates. There were no significant interactions between factors for any measured variables.
