USGA Topdressing Sand

"USGA" is an acronym for the United States Golf Association. This is used to describe sand to confirm that it meets the USGA recommended spec for topdressing. This material will achieve the following: 

  • Improved Smoothness – Voids exist within the turf canopy between turfgrass leaves and stems, causing inconsistent ball roll. Sand topdressing helps fill these voids to provide smoother and truer putts.

  • Thatch Dilution – The layer of organic debris, stems, crowns and roots in the upper rootzone – i.e., thatch – can become concentrated and encourage mower scalping and localized dry spots. Thatch should be diluted with sand through practices like verticutting and sand topdressing to maintain good turf quality.

  • Improved Turf Recovery – Occasional turf thinning can occur on putting greens. Sand helps cushion leaf tips and crowns and reduces algae.

  • Increased Firmness – Turf produces organic matter in the upper rootzone that creates soft, spongy playing conditions. Regular sand topdressing, along with core aeration, improves surface firmness and resiliency.

  • Improved Rootzone – Sand drains well and resists soil compaction. The accumulation of sand from multiple topdressings over many years can improve soil physical properties.
