We have recently completed our scheduled fairway aeration and topdressing on the back nine and are almost complete with the front nine. Our new Santa Anna Hybrid Bermuda fairway turf is a warm season grass that will recover rapidly during the warmer weather of summer. In 2024 we are going to schedule our spring aeration and fairway topdressing closer to the end of spring when the warmer recovery weather will be more predictable then in April.
This aeration was the first core aeration to these fairways since they were sprigged in the summer of 2021. This process will be very beneficial to the overall health and performance of these new fairway surfaces and will allow for more consistent moisture throughout the soil profile. Additionally getting another 30 to 40 tons per acre of sand topdressing down will continue to smooth and fine tune these surfaces. This will be the 4th sand topdressing since sprigging in 2021, and we have noticed a difference in fairway smoothness after each one of them. They will continue to get better with each subsequent topdressing in the years to come. Below are pictures of the process we employed this past week.

First step is to flag all of the sprinkler heads, valve boxes and yardage markers so tractor operator can hopefully avoid them. I spent allot of time on one of our two fairway aerators, The Toro Procore 1298, and can share a couple of things. First the Procore is a wonderful, state of the art fairway aerator that feels like your pulling a sewing machine when the soil conditions are good, but when the soil conditions are not so good, which is vastly more often then not on our property, it feels like your pulling a cluster bomb. Its was a not so subtle reminder of the main overall challenge of this property, the native soil. Secondly avoiding all those sprinkler heads, valve boxes and yardage markers identified with the little white flags is another challenge all unto itself. Above is a good image of the actual aeration process. We uses 3/4" coring tines that were penetrating as deep 2"- 3", depending on the soil, so yes more 2" depths then 3". |

Above is a closeup of the actual cores pulled during the process and the holes awaiting to be filled with sand, then irrigation so it can penetrate and soak and hydrate the profile. |
 |
After the cores have been allowed to dry for awhile, we use a keystone drag mat to break up the cores. Some of the soil we are trying to extract and replace does remain because of this but it mixes with the organic matter and subsequent sand topdressing making it a much better growing medium. |
 |
Next we start to use our turbine blowers to wind row the cores and debris for removal as well as clean the surface after sweeping and mowing. |

Next comes the sweepers which sweep up all of the cores and debris |
 |
After cleanup, The Man, The legend, Enrique Reyes Huerta starts to topdress with topdressing sand. This represents an application rate of about 30 to 40 tons of sand per acre. |
 |
The sand is allowed to dry then we start to drag it into the aeration holes and turf canopy with the same keystone mat that we used to break up the extracted cores |
 |
Prior to aeration we turn off irrigation for a day or two. So after the sand is properly drug in, we irrigate fairly heavily, (0.30" - 0.50"), to push the sand further into the aeration holes and turf canopy as well as hydrate the soil profile. The following day we apply fertility and wetting agents to help out further irrigation events and promote recovery. |

#12 Fairway on Tuesday 7/25/23. We core aerated & processed this on Tuesday 7/18/23 7 days prior and topdressed on Wednesday 7/19/23 only 6 days prior. The nature of the warm season Hybrid Bermuda recovers very rapidly during the long days and warm weather of summer. |
