| Abstract/Contents: | Presents a study initiated during 2009 "[to] compare core aeration and aggressive verticutting with sand injection for their abilities to affect organic matter content in the rootzone of ultradwarf bermudagrass greens." Details methods and materials used during the experiment, noting that "soil samples were collected from each treatment replicate using a hole cutter before cultivation on September 30, 2010." Reports that "the core-aerifying technique affected 6.5% [percent] of the surface area of the green at each event. A total of 13% of the surface area of the green was affected by the two cultivations. The aggressive verticutting implement treated 8% of the green's surface with each pass, and the total was 16% for two passes at each event." Provides a chart that illustrates inches of penetration before and after two cultivations on an ultradwarf green. Concludes that "verticutting treatments resulted in a slightly more firm green than no cultivation or core removal alone," and that "USGA [United States Golf Association] TruFirm measurements showed the green was softer soon after cultivation treatments. The green became firm approximately one month after cultivations." |

| USGA Summary Points: | Cultivation techniques applied twice reduced organic matter content at various depths on a 'MiniVerde' ultradwarf green. The greatest OM reduction of 68% at 1-inch depth was observed for the core removal combined with aggressive verticutting. Verticutting alone reduced OM 55%, and core removal alone reduced OM 36%. Ball roll was not consistent for cultivation treatments. USGA TruFirm measurements showed the green was softer soon after cultivation treatments. The green became firm approximately 1 month after cultivations. Verticutting treatments resulted in a slightly more firm green than no cultivation or core removal alone. |
