Frequent Non-Disruptive Aeration Is A Necessity

Organic matter build-up in the surface of newly constructed putting greens is a serious issue affecting the long term preference of the putting surface. Researchers at the University of Georgia investigated several aerification methods to limit this phenomenon. Among their findings include:

• When hollow-tine core aeration is conducted with holes filled by topdressing, the duration of improved SHC (saturated hydraulic conductivity) is usually 5-8 weeks for 1/2" to 5/8-inch diameter holes on high sand greens.
• Non-disruptive cultivation should be initiated within five to eight weeks after a hollow-tine cultivation operation and repeated on a three-week schedule to maintain high rootzone SHC and gas exchange during the summer months.
