Chief Agronomist Andy Johnston and the Agronomy team topdressing Tees and Greens.
Topdressing covers the crown of the plant of partially buries it and protected from scalping by the mower blades. Topdressing the greens prevents MOST scalping of the leave blade, therefore preventing unwanted disease.
Sand helps to break down organic matter by increasing porosity and helping the soil breathe. We have topdressed nearly every Monday since my arrival and have built up nearly 1/2″ of sand in the top of the greens profile. Because of this, our greens have stayed drier and firmer and will continue to get better as we continue to remove organic matter via aerification and continue topdressing to dilute the organic build up.
With the addition of sand, we have been able to firm up our greens and smooth the putting surface. Sand fills in slight imperfections to allow better ball roll and firms up the surface since sand holds less water than organic material in the soil below. I know many golfers feel that sand on the greens equals slow greens. In most cases, after a light dusting, the greens are slightly faster than before because a smoother surface is achieved.
