2013 Summer Fairway Aerification
Submitted by Craig

On 7/8/13
we began aerifying the fairways at Cowan Creek.
The following paragraphs and figures will explain the process we used,
the difficulties we discovered, an explanation of the need for periodic fairway
aerifications.
The
original plan was to pull a core out of the fairways, pulverize the plugs, then
drag the plugs back in. However, in
preparation of the process we discovered that the fairways suffered from
excessive compaction from cart and machine traffic (as seen in figure A).
(180 lbs without
being able to force the probe through the root zone)
We had
difficulty using a hollow tine to pull cores at a sufficient depth, and some of
the tines broke during the trial process.
We made an adjustment to our game plan and used a shatter tine on an
Aerway ™ aerifier (Figure B and C). The
shatter tine allowed us to break through the turf and the rootzone to a depth
up to 6” in the soil. A key benefit to
using a shatter tine as opposed to a regular slicer is the offset setup of the
tines, leaning them away from the vertical line (Figure B). As the tine exits the ground, it moves the
soil laterally and fluffs the soil to decrease compaction.
Although
great for long-term health of the turf, the temporary negative effects of this
process are evident for several days.
The shatter tine leaves a 4-5” slit in the turf (Figure F), and the turf
is lifted up one side upon exit. This causes
the aerified areas to be bumpy. We are
currently using a pull-behind drum roller to smooth out the tufted areas
(Figure G), and over time this practice along with general cart traffic will
return the fairways back to normal.
Both White
Wing and Legacy Hills are scheduled for fairway aerifications in the upcoming
weeks. We will continue this (as well as pulling cores) in the future to
alleviate our compaction issues. These
practices in conjunction with flushing and fertilizer amendments will help us
maintain the best playing conditions over a long period of time.
