· Thatch management: Like I have mentioned above, the sand is used to dilute and replace the organic matter that builds up at surface, without verticutting and topdressing the green will be come soft and spongy and encourage mower scalping and localized dry spot.
· Smooth and firm the surface: Sand is used to replace the voids which exits in the turf canopy to produce a firm and smooth putting surface. This encourages an upright growth habit as well.
· Protect the crown of the plant: The sand gives the crown of the plant a cushion from the impact of the ball and protects it from the elements to maintain turf health and quality. Also allows us to maintain a lower mowing height.
· Improve root zone and drainage: Overtime the buildup from sand topdressing will improve soil physical properties. Since sand drains better than a native soil it will help keep the water moving through the profile creating a firmer surface. Sand also resists compaction as well, which is very important with all the traffic that a putting green receives.
All of these benefits combined will make for a much healthier turf stand as well as a quality putting surface and a much better golfing experience.
