Abstract/Contents: | "Organic matter build-up in the surface of newly constructed putting greens is a serious issue affecting the long-term performance of the putting surface. Researchers at the University of Georgia investigated several aerification methods to limit this phenomon [phenomenon]. Among their findings include: The immediate increase in saturated hydraulic conductive (SHC) following cultivation treatment demonstrates that the surface conditions do control SHC on high content sand greens and that creation of temporary macropores across this zone results in SHC that is substantially higher. Most cultivation operations that create at least of 14 - inch diameter hole can dramatically and immediately enhance SHC. Saturated hydraulic conductivy [conductivity] then declines over time. These responses have impact on cultivation timing and frequency. When hollow-tine core aeration is conducted with holes filled by topdressing, the duration of improved SHC is usually 5-8 weeks for 12- to 58-inch diameter holes on high sand greens. Non-disruptive cultivation (i.e. high-pressure water injection) 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." |
