This last week we aerified the fairways and approaches. We used 5/8" O.D.tines and backfilled with mortar sand. Last year we budgeted for USGA spec sand, but after doing some thinking I sent a sample of mortar sand to Hummel for testing and comparison of our soils. The test came back positive and we were able to save over 7 dollars a ton. When it takes about 1000 ton to complete the fairways it becomes a heafty savings.
Our fairways have no soil whatsoever. We have 2-3 inches of thatch and then decomposed granite. Since no aerification practices were kept up over the past 10 years since the courses conception the fairways have just gotten worse. With no cultivation practices in place it was a chore to get anything more than two inches in depth. This year we moved it to two and a half inches but had several problems with the aerifiers breaking down.
When I first arrived on the property the fairways were so wet since all the turf was grown in the top 2". The average drive would plug in the thatch layer and the main complaint was why can we never get roll. The members would say they couldn't wait until winter when the course freezes to get better roll. Heartbreaking comments when your passion is golf course management.
With the aerification process now in place we are getting much better roll. Our goal is to enhance the soil enough to get roots to go beyond the thatch layer. The course has never been in better shape since the grow-in of the club. Back when they had no thatch problem on the entire course. Now times have changed and we are trying to rescue a course from years of neglect. It is pretty nice to know that you can make a difference just by following the basics of turf management.
Back to our operation on the fairways. We aerified the fairways, intermediate cut and approaches. We used two tractor aerifiers to punch holes and three vacuums to clean up the plugs left behind. While the vacuums cleaned the fairway I had a blower crew following them to do the final touches before we spread the sand. We used two Dakota topdressers towed behind tractors to spread about 2 tenths of an inch of sand over the surface and then dragged it into the holes. No fertilizer was applied before aerification, but 3/4 N/M will be applied this next week
over the entire course.
Once we dragged the fairways with the steel drag mat we needed to follow up with a tractor blower to take care of missed plugs and any heavy areas that were difficult to drag in. The course aerification has turned out to be very successful despite the amount of breakdowns we had throughout the process. Last year was our first go at the process and it took us two weeks with many breakdowns and in-adequate vacuums. This year we rented a vacuum and got it done in four days.
I think we all know the importance of aerification and this is the first membership that can't wait for us to aerify the fairways. They understand the fatal mistake of not being consistent in the past and they now have to pay for it with below average playing conditions form the abundance of thatch.
