Topdressing Amenity and Playing Turf
Different types of topdressing situations occur:
Upgrading poor quality playing surfaces. eg a badly degraded council oval or golf fairway constructed basically on natural soil where topdressing is needed to impose a new and more favourable particle size distribution in the surface soil. Here topdressing may be simply a program of say 3 dressings over summer to build up 20 mm of sandy root zone on top of the natural soil to prevent compaction, followed by a once yearly topdressing as needed.
