| Abstract/Contents: | "Researchers at Virginia Tech investigated several spring and fall cultivation treatments to minimize both organic matter in the thatch/mat layer and recovery time of bentgrass putting green turf from the cultivation treatment. The results of their three-year study include: The control plots finished with the greatest thatch/mat organic matter (4.3%), but this 0.5 to 1% increase compared to more aggressive treatments, did not result in lower visual quality. At the end of 2008, only those coring treatments that removed 14.8% to 19.6% significantly reduced % organic matter compared to the topdressed control. At the end of 2009, all treatments, except verticutting alone, significantly decreased % organic matter in the thatch/mat layer compared to the topdressed control. Using large tines (0.5" id) at a close spacing both spring and fall each year (19.6% surface removal) worked best in terms of reducing final organic matter at 3.1%, but required approximately 5 to 15 extra days of recovery each season for recovery compared to the small tine and/or verticutting treatments. Annual removal of 15 to 20% surface area should be the goal for adequate dilution of organic matter in creeping bentgrass greens." |
