Deep Tine Aerator on 12 Green
The advantage to this style of aeration is two fold: 1.) aeration holes can be go as deep as 9" (versus 3.5"-4" for regular aeration) and 2.) the machine has the ability to loosen the subsurface for greater relief of compaction. The "kick" that relieves the subsurface compaction can also fluff up the greens (mostly because of our limited roots and heavy soils) and tends to make the surface bumpy. We do use 5-10% kick during our late fall aeration when play has stopped. To be fair, this time out we were only interested in creating holes for air exchange/water infiltration.
Needle Tine Holes
We were only able to get about 7" penetration and went with a slightly larger spacing. We could have gone the full depth and double the tines to get the biggest bang for our buck but with this type of aeration you need to fiddle around quite a bit to find the happiest medium between surface disruption (i.e. playability) and intensity of aeration. As we do more of this style of aeration and, hopefully, the greens overall health increases we should be able to go deeper and tighter. The real interesting part about this process is how and why are able to accomplish it. The general benefits of aeration (air exchange, compaction relief, thatch removal, blah, blah, blah) I'll harp on about in other posts. What I would like to cover here is the savings and the unique relationship that have developed. In the past we would contract out the deep tine to the tune of over $4000/aeration and since we weren't on the "A" list of clients we had to take whatever date the contractor offered. The very last time the contractor was able to fit us in the greens were frozen. As a result, and $4000 later, there was some greens we were unable to aerate completely and others that were damaged. Since buying our own deep tine aerator for $22,000 we have been able to deep tine 3 times at times that suit us. At the end of this year we will do one more deep tine for a total of 4 and a savings of $16,000. By the end of next year --assuming we keep the same schedule--we will have paid for the deep tine. There is costs associated with owning a machine but for the first few years those are mostly the cost of tines. The unique relationship part of this story relates to the tractor needed to operate the deep tine aerator. The tractor required needs to be of a minimum horse power and have a ultra low gear selection (sometimes called a "creeper gear") not to mention wide tires. KGC's tractor has none of these. As luck would have it, Trickle Creek does have a tractor that meets this requirements and they contract out their deep tine aeration's. So KGC has a deep tine aerator with no tractor to operate it and Trickle has tractor but pays to have their greens deep tined. This scenario obviously lead to a relationship that is best represented by the over used and usually self serving phrase "a Win/Win situation". With the two local golf course working together and sharing equipment we are able to take advantage of a highly specialized tool. Ultimately, KGC will have to replace our old Ford tractor but with the initial success of this particular equipment sharing experiment there is a possibility for local courses to purchase other specialized equipment and share amongst ourselves.
River Watch
August 8th
The huge rain events that kept coming last week have made watering a no brainer. But as you can see the river still continues to drop. There is more water at the river intake this year versus other years and as the middle of August approaches the watering requirements are usually less than early in the year so things appear "rosy". I feel a little bit like Chicken Little, but history is on my side.
