A key chapter
in any golf course management plan must be that of turf and pest
management. Issues such as chemical use, irrigation, greenkeeper
training and waste management are part of the fundamental activities
of every greenkeeper. Clearly these can have an impact on the environment,
and following best practice in these areas will reduce the potential
for groundwater pollution, spillages, disturbance to wildlife and
so on. Many of these aspects are related to good Health and Safety
practice and therefore are necessary to comply with legislation.
For the purposes
of the Club's management plan it is essential to clearly document
your policies and practices in these areas. This provides a basis
from which practices can be evaluated, and possible future enhancements
identified.
The following
guidance should assist you in preparing a detailed overview of how
the playing area is maintained, in terms of cutting regimes, cultural
management of turf, chemical usage, irrigation and pest control.
It will also cover the qualifications of green staff, and how they
are trained to ensure all activities are carried out to high environmental
standards.
To begin the
preparation of your turf maintenance policy you should summarise
your practices for tees, greens, aprons, fairways, semi-rough, rough
and deep rough, using the following format.
Turf varieties:
- Are cultivars
suitable for soils and climate?
- Are they
the most durable, drought resistant species?
- Are they
native to the area?
Cultural
management:
- What are
your mowing heights?
- How do you
avoid overstressing of turf?
- What are
your aeration and anti-compaction measures?
- Do you monitor
and control thatch?
- How often
do you hollow core, slit tine, verti-drain etc?
- Do you apply
top dressing and how often?
- How do you
control thatch?
Fertiliser
use:
- What are
your application rates and quantities for each area of the course?
- Do any areas
require additional applications?
- What are
your application methods?
- What types
of fertiliser do you apply?
- Do you use
natural/organic fertilisers?
- How is it
applied?
- Are their
any areas that you do not apply fertiliser, such as close
to ditches and water features, near wildflower areas, or within
semi rough.
Pesticide
use:
- Do you regularly
scout the course for signs of pests and disease?
- Do you set
threshold levels for different types of pest and disease in certain
areas? Is there a certain level of disease that the club feel
does not warrant treatment?
- Do you look
at product toxicity and persistence when purchasing?
- Do you adhere
to strict application techniques? Such as weather conditions,
no spraying in windy conditions.
- Do you use
any anti drift equipment? Nozzles on sprayers, drift guards and
similar equipment.
- Do you know
the minimum amount of a given product to cure a problem in a given
location?
- Do you apply
pesticides in spot treatments to cure problems, or do you undertake
widespread, preventative treatments?
Integrated Pest and Turf Management
Cultural Controls:
- Select turf species appropriate for climate and soils, which
may require least intensive management and prove to be most durable.
- Regularly scout the course for disease and pests.
- Identify local disease, and hot spots for recurring problems.
- Apply chemical controls on a curative rather than preventative
basis to help minimise coverage
- Use slow release or natural-organic fertiliser.
- Monitor and control thatch using mechanical and cultural techniques.
- Ensure good aeration and anti-compaction practices.
- Initiate ongoing programme of traffic management to help spread
wear and reduce erosion.
- Set thresholds.
Practical Applications:
- Only treat area in correct climatic conditions ie. if spraying
only on calm days, using correct water pressure to avoid spray
drift.
- Apply chemicals as directed by the manufacturer.
- Use minimum amount required to cure problems.
- Choose least toxic substances.
- Apply chemicals only when absolutely necessary, after other
methods have been attempted
- Allow buffer strips of rough vegetation to develop alongside
water features or ditches to avoid contamination, both directly
and through runoff.
- Avoid application of any fertiliser or pesticide with 3 metres
of water courses with hand held sprayers, and avoid any application
within semi-rough.
- Undertake and audit of current management practices, for inclusion
in the Management Plan
