JHGTC Tip of the Week
Thanks to Rick Stuck for
helping out with this week’s tip.
When at the
practice tee, please make your divots in a straight line backwards. For
example: After you hit a shot, place the ball directly behind and on the
edge of the divot you previously made. See article below.
Practice Like A Pro

Randomly
scattered divots (on the left) remove up to 50% more turf than practicing in
a linear pattern (on the right) where each new shot is placed directly behind
the previous divot.

Late July is usually the time when there is a
lack of turf coverage on practice range tees established with cool-season turf
grasses, such as creeping bentgrass or Kentucky bluegrass. Heavy play removes
divots faster than the turf can recover, and hot, dry summer conditions leave
little opportunity for seedling establishment or regenerative growth of
surrounding turf. Poor turf coverage that comes in mid-summer generally indicates
that the practice tee is simply undersized for the amount of play received,
i.e. there is not enough time for turf to recover before tee stalls are
returned to previous locations. It also indicates that tee stall rotations need
to be reviewed for efficiency and that synthetic turf options should be
considered at the rear of the tee to provide the additional time needed for
turf recovery.
With the exception of an efficient tee stall
rotation, enlarging the tee(s) and adding synthetic turf are improvements
typically left for the off-season when time and funds become available. So,
until then, what can be done? The solution resides with golfers. Since randomly
scattering divots can quickly destroy a practice range tee, the better approach
is to shrink one’s divots by removing them in a pattern just like the
professionals. More specifically, this includes placing each shot directly
behind the previous divot. This can easily be repeated for up to 10 shots
resulting in much less turf being removed.
Let’s take a look at a practical example that was
provided by Golf Course Superintendent Chris Pekarek at The Village Links of
Glen Ellyn in Illinois. Mr. Pekarek estimates more than 2 million shots are
taken annually from the 1.25-acre Kentucky bluegrass practice tee and that 1.5
million of the shots result in turf removal. Although divots come in all sizes,
the average iron shot is believed to remove a divot 3 inches wide by 6.5 inches
long for a total of 19.5 square inches. After just 30 shots, or a small bucket
of balls, 4.1 square feet of turf are removed, given a typical practice routine
(30 shots x 19.5 in2 = 585 in2 / 144 in2 = 4.1 ft2). Therefore, after an entire season, 205,000 square feet of
divots are removed from the tee. That's more than 4.6 acres of turf from their
1.25-acre surface.
If instead each shot is played directly behind
the previous divot, subsequent divots are reduced to an average size of 3
inches wide by 3 inches long, or 9 square inches. After 30 shots, this pattern
removes only 2.1 square feet of turf. (As the first divot removes 19.5 square
inches and the subsequent 9 divots remove 9 square inches each for a total of
81 square inches, a total of 100.5 square inches is removed for every 10 shots,
which is typical for this linear pattern. For 30 shots or a small bucket of
balls, 3 x 100.5 = 301.5 in2 / 144 in2 = 2.1ft2 are removed.) If everyone adopted this method, the annual
number of divots removed would be reduced from 205,000 square feet to just
105,000 square feet. That’s nearly a 50% reduction in the amount of turf
removed.
Implementing this simple divot pattern into your
practice regime has significant season-long implications at your facility. So,
rather than voice a complaint about the turf during oppressive conditions in
July and August, do the turf a favor and practice like a pro!
