Optimal topdressing applications for athletic fields determined

Scientists evaluated the effects of cumulative sand topdressing rates on the fall wear tolerance and surface shear strength of simulated athletic fields. Experimental results suggested that a 0.5-inch topdressing depth applied over a 5-week period in summer will provide improved shoot density and surface shear strength in the subsequent fall. Results also indicated that topdressing rates as thick as 4.0 inches accumulated over a 2-year period provide increased shoot density but diminished surface shear strength.
