Fall 2016 Fairway Aeration
Linked here is another article from the USGA that addresses Aeration Timing
and the perfectly legitimate question of why do "they always aerify the golf course when everything is perfect".
Also in the spirit of managing expectations and communicating the hows and whys of what we are doing on the golf course, below is another pictorial covering recent fairway aeration for those interested members.
|Step #1 - Flag sprinkler heads. A HUGE necessity of the aerification process is avoiding hitting sprinkler heads with the aerifier. We also have to flag yardage markers and drainage inlets so the equipment operator can see them and maneuver around or in most instances lift and lower aerifier over sprinkler head|
|Step #2 - Aerify the fairway. Above picture is a brand new aerifier that we are using for the first time here at Granite Bay. Very smooth piece of equipment that is designed so tractor tires don't run over wet cores which smash cores into turf which is hard to mechanically pick up.|
|First pass on #15 fairway. The voids are where the aerifier was lifted over a sprinkler head, yardage marker and / or drainage inlets.|
| Step #3 - Dragging aerification cores to break them up. All of the pictures we have been presenting have been taken in daylight. Much of the actual aerification is done in the dark early morning hours so when these cores are removed they are wet. It is imperative that the cores are allowed to dry to a certain extent before we attempt to process and remove. Believe me, we have tried removing the cores directly after they were extracted resulting in a muddy mess that requires more cleanup and an inferior result of mud smashed into the fairway surface. We do turn the water off to a certain degree to mitigate wet conditions, but if the the turf is overly dry during aerification substantial damage will occur as well. The need for this necessary drying is what drove the decision years ago to have alternating F9 / B9 closures during the aerification season. |
|Step #4 - Vacuuming / Sweeping debris. All of this debris is stockpiled and composted in the nursery green area off of #4 fairway.|
|Another reason for the alternating closures is this is a noisy, dusty dirty process that is best done without the presence of golfers.|
|Step #5 - Blowing behind the sweeper to get the surface even cleaner.|
|Step #6 - Mowing to clean up little tufts that are drug up during the cleanup process.|
|Step #7 - Broadcasting seed. There are many ways to introduce seed to the turf canopy. Here we are broadcasting seed over the aerified, cleaned & mowed fairway surface ahead of applying sand topdressing. |
|Ryegrass in the spreader hopper.|
|Step #8 - Apply sand topdressing. |
|Old Tom Morris. His battle cry was rumored to be " more sand!"|
|Step #9 - Dragging in the sand topdressing.|
After this dragging of the topdressing we normally mow again to even out the playing surface and mow down the tufts created by the drag mat. With all of that seed and sand down we do need to keep things moist to ensure good seed germination. Weather forecast for the next 10 days are for highs in the mid 70's to mid 80's and nighttime lows in the low to mid 50's which is perfect for cool season turf recovery and ryegrass germination. We should be in very good shape by the time Jones Cup rolls around.
Next week we will finish fairways on Monday and start surrounds Tuesday on the back 9. Below I have included the 2016 Fall aerification schedule again for a reference. Thanks
