FAQ - Golf Course Maintenance and Agronomics
If this section does not answer your particular
question, please post your Turf Management questions here.

At a recent
Green Committee meeting our golf course superintendent suggested
closing the course for one day a week to accomplish essential agronomic
practices. Will this really help? top
Closing the golf course on a regular schedule is a good way to
improve course conditioning when important agronomic practices
cannot be performed due to heavy play. Important preventative
maintenance can be done in a timely manner, and worker productivity
improves significantly. For example, productivity can drop by
as much as 40% when the maintenance staff encounters golfers on
the course because they are obligated to step aside and wait.
Our
greens were in great shape and now our golf course superintendent
ruined them by punching holes all over them. I think she is being
overprotective of them and just too stubborn to change her ways.
Is this aeration all that important? top
Aeration is an extremely important maintenance practice. Although
it results in a temporary disruption of the green, aeration improves
water penetration into the soil, reduces soil compaction, stimulates
turfgrass root growth for a healthier plant, helps control thatch
build-up, and improves overall growing conditions. Aeration generally
is done once or twice per year, and sometimes more often if certain
problems exist.
Think of it like going to the dentist for your twice-yearly check-up.
The same holds true for aeration. You can skip a visit to the
dentist, but you will contribute to problems over the long term.
You can skip one of the semi-annual aerations, but this can result
in a faster turf loss. Your superintendent isn’t being overprotective.
She is doing exactly what should be done to ensure long-term turf
health.
What
is the Stimpmeter and how does it work? top
The Stimpmeterâ is a 36-inch long, aluminum tool used by golf course superintendents
to make a standard measurement of the relative speed and uniformity
of their greens. A Stimpmeter reading is actually a distance
measurement in feet and inches.
At one end is a ball release notch that is designed so that a
golf ball will always be released and start to roll when the Stimpmeter
is raised to an angle of approximately 20 degrees to horizontal.
The basic steps to measure green speed start by rolling three
golf balls in one direction on a level area of the green. The
three distances are measured and averaged. Using the average
stopping point of the first three golf balls, this step is repeated
along the same line, but in the opposite direction. The distances
obtained in steps one and two are averaged, resulting in the Stimpmeter
reading for the green. The longer the distance, the faster the
green. A reading of 8 – 9 feet is considered a medium to fast
speed for day-to-day play.
The Stimpmeter is a helpful management tool for the golf course
superintendent in providing smooth, consistent putting surfaces,
but is not intended for course-to course comparisons by golfers.
I’ve
played a lot of golf courses and have seen hole locations all over
the place. What is the USGA’s recommendations regarding hole locations? top
The USGA frequently receives requests for guidelines with respect
to selection of hole locations on the putting greens, particularly
during competitions. There are no rules regarding hole locations,
so there is no such thing as an "illegal" hole location.
However, we do have some guidelines.
Many factors affect selection of hole locations. The first and
most important is good judgment in deciding what will give fair
results. Do not be tricky in locating holes. There should be
enough putting green surface between the hole and the front and
the sides of the green to accommodate the required shot.
In any case, it generally is recommended that the hole be located
at least five paces from any edge of the green. If a bunker is
close to the edge, or if the ground slopes away from the edge,
the distance should be greater, especially if the shot is more
than a pitch.
An area two to three feet in radius around the hole should be
as nearly level as possible and of uniform grade. A player above
the hole should be able to stop the ball at the hole. Consider
the condition of nearby turf, especially taking care to avoid
old hole plugs that have not completely healed.
We
have bentgrass fairways and I’m confused as to what to do with my
divots. Are we better off replacing the divot or just filling the
scar with the sand/seed mix that’s provided? top
If the divot has some soil attached and hasn’t been blown into
a hundred pieces, it will heal quickly if it is replaced immediately.
Be sure to replace the divot (green side up!) and step on it to
establish contact with the soil below. If the divot cannot be
replaced, then the sand/seed mixture should be used in the scarred
area. Golfers who take the time to replace a divot properly or
repair divot areas help keep the fairways in good condition for
their fellow golfers.
We have bermudagrass fairways at our golf course. I want to
be mindful of the proper etiquette, so how do I handle any fairway
divots that I might create?
When the bermudagrass is actively growing, applying straight
sand or a prepared mix to the divot areas will help the scar heal
rapidly and level the playing surface for your fellow golfers.
The same procedure can be used when the bermudagrass is dormant
or if the surface has been overseeded for the winter months.
What
are the USGA’s recommendations when selecting sand for bunkers? top
The USGA has never had specifications for bunker sands. The article
"Selecting and Handling Sand," Green Section Record,
November/December 1983, provides general guidelines regarding
the sand's particle size, shape, composition, color, and other
factors that will be helpful for the initial selection process.
Remember, a sand’s playability is subjective. It is a good idea
to develop a test bunker so that several of the potential sands
can be installed and sampled by the golfers. The test bunker should
be used for several months before a final decision is made. This
will help form a general consensus that will be useful in the
ultimate selection of the sand. Keep in mind, bunker sand becomes
firmer over time, as it becomes contaminated with soil and organic
particles.
Should
bunker rakes be placed inside or outside of the bunker? top
There is no set rule as to where the bunker rake should be placed.
It is recommended that rakes be placed outside bunkers and in
positions where they will be least likely to affect play. Other
considerations, such as golf course maintenance and the size and
design of the bunkers, will impact the final decision made at
each course.
Our
golf course is developing a master plan for renovating the course.
The proposal includes the removal of many trees around the greens
and tees. I hate to see even one removed. Is it normal to remove
so many trees? top
Many golf courses implement tree-planting programs that result
in over-crowded trees. As the trees mature, they dramatically
affect the way the course plays and create increased shade and
reduced air movement around the green and tee areas. This condition
results in weakened turf that needs more irrigation, fertilizer,
and pesticides to grow. Good turf needs good growing conditions,
and tree removal is an essential part of master plans on many
older courses.
