In addition to full course aeration, the excellent fall weather has allowed us to continue with aggressive subsurface drainage repair and additions. Here we show two "vents" being added to the back of #15 green. (Vents are surface exposure of 4" drainage pipe connected to the subsurface network). With no disruption to the actual green we utilized a drainage camera to map the subsurface drainage grid. We located spots for two vents at the back of the green. On this particular green we also located and opened two exits that were completely buried under rock and soil. Together this work will allow for the window effect, that is, to allow for air and water to move through the piping network similar to opening a window in your home. If you open one window there is no air flow. If you open a second window this allows for the air to move freely through the home. In this case it allows air to move more feely in the rootzone of the green, keeping grass roots healthy with the addition of extra oxygen and ensuring water movement out of the green. This has been very successful with many of our greens as in 2010 we have added 22 vents to date around the greens. We have also repaired and exposed 15 different drainage exits.
