This was my communications with the GAC from the August Meeting:
I extend my
warm greetings to all of you and express my gratitude for the opportunity to
address the golf activities committee today. I am delighted to provide you with
a comprehensive update on the current state of the golf course, detailing the
activities that transpired during the month of July and outlining our plans for
August and September.
July has
consistently proven to be a demanding month for the health of the golf course
due to the extreme fluctuations in temperature and humidity. As we all know,
our golf course predominantly features cool-season grass species, which are not
well-suited to thrive under high-temperature conditions. The scorching air and
soil temperatures during July pose significant challenges for the best grass
plant's health, resulting in up to 50% root loss when soil temperatures reach
the range of 75 to 77 degrees Fahrenheit.
Understanding
the optimal conditions for root and shoot growth is crucial to maintaining a
healthy golf course. For optimal root growth, soil temperatures between 50 to
65 degrees are ideal, while the growth on the top part of the grass (shoots)
occurs optimally between 60 to 75 degrees Fahrenheit. These insights highlight
the sensitivity of our turf to temperature fluctuations, and it emphasizes the
importance of mitigating extreme conditions to ensure the longevity of our
playing surfaces.
One critical
aspect that we need to address during July and August is the traffic the golf
course receives. It is during these months that we witness the highest amount
of play and member participation, along with hosting outside events that add to
the wear and tear on the course. Unfortunately, this period also coincides with
the weakest state of our bentgrass, making it less capable of recuperating from
the damage inflicted by this high level of activity.
Moreover,
the fairways present a specific challenge due to their construction on native
soil, which has not undergone modification. When the fairways were initially
constructed in 1981, the grass was seeded and grown on the existing soil, with
no specific amendments. Consequently, we are left with a predominantly clay
soil type that is poorly drained, leading to prolonged periods of wetness when
we receive precipitation. This excess moisture negatively impacts the root zone
of the turfgrass, hampering its health and resilience.
Throughout
the summer months, we face numerous issues with turf damage, which typically
takes a significant amount of time to heal. The physiological characteristics
of bentgrass make it more vulnerable during this period, compounding the
challenges we encounter as turfgrass managers. The damages caused by various
sources, whether it be due to excessive traffic, pests, or extreme weather
conditions, demand extensive time and effort to restore the health of our golf
course.
A crucial
factor that often goes unnoticed when considering turfgrass health is the soil
structure and compaction. There are pockets of soil with favorable conditions
for growth, but there are also areas with poor soil that hinders the grass's
development. A simple test using a screwdriver can demonstrate this; in healthy
areas, the screwdriver can penetrate deeply, but in problematic spots, it
barely goes half an inch without additional force. Addressing this issue
necessitates careful management and tailored approaches to different areas
based on their soil characteristics.
Pest
management plays a pivotal role in maintaining the quality of our turf during
the summer months. This is the time when we face the highest levels of disease
and insect pressure. Effective management requires the application of chemicals
to prioritize high-traffic areas such as greens, tees, and fairways, while less
protected areas like roughs receive limited protection. Though it is a
significant expense, such practices are typical for golf courses in this region
and are essential for preserving the overall health and playability of the
course.
The heart of
the playability of our golf course lies in the management of irrigation and
moisture levels in the soil. Various aspects of the game, such as the distance
of ball roll on fairways, the speed of the greens during putting, and the
greens' receptiveness to shots, are all heavily influenced by the amount of
water in the soil. On newer greens, constructed in the early 90s and onwards,
were built following USGA specifications, using sand as the root zone mixture.
This sand-based approach allowed for proper drainage and moisture retention,
ensuring that greens remain in good condition during both wet and dry periods.
However,
over time, the buildup of organic matter and thatch in the green profile has
made the greens spongier and harder to drain effectively. While we strive to
provide optimal conditions by carefully monitoring moisture levels and
minimizing water usage, some areas, particularly those with poor soil
conditions, suffer from inconsistent results. Additionally, the turning of
mowers on the edges of greens can cause compaction and stress on the turf,
contributing to the issues faced by certain areas.
As we
approach the fall, our focus will shift towards total golf course aerification.
This critical process involves aggressive core removal and generous sand
topdressing on greens, tees, fairways, and roughs to improve the turf's health
and resilience. Although the impact may take time to fully materialize, this
investment is vital for the long-term sustainability of our golf course. Core
removal aerification helps to relieve compaction, increase soil oxygen levels,
and enhance water penetration and root growth.
It is worth
noting that aerification is not without its challenges. As much as we'd like to
undertake more frequent and extensive aerification processes, we must strike a
balance between necessary maintenance and providing optimal playing conditions
for our members. Implementing a more aggressive schedule would lead to
significant disruptions and inconvenience for golfers, and thus, we must
carefully plan and strategize our aerification efforts to ensure a seamless
transition.
For August,
September, October, and November, we will continue regular golf course
maintenance activities, such as mowing greens, tees, fairways, and roughs, as
well as maintaining sand traps and landscape beds. During these months, the
turfgrass typically experiences slowed growth, which allows us to reduce mowing
frequency in certain areas while still maintaining playability.
Additionally,
the winter months offer an ideal window for minor golf course renovations.
These projects may include fairway and rough drainage installation, leveling
tees, constructing new tees, relocating tee boxes, and enlarging tee surfaces.
We also plan to address tree under brushing and perform any necessary minor
infrastructure or fairway repairs, such as fixing stonewalls or edging of cart
paths.
In
conclusion, I am optimistic about the future of our golf course, as we continue
to implement strategies and prioritize maintenance efforts to improve and
sustain the health of our turf. Your support and understanding are vital in
this endeavor, as we work tirelessly to provide the best possible golfing
experience for our esteemed members. I am thankful for the opportunity to share
these insights with you today, and I am more than happy to address any
questions or concerns you may have.
Thank you
for your attention.
Sincerely,
Josh
Laughridge
Director of Golf Maintenance
