Feature
is particularly important in a stadium
environment where the groundsman is,
essentially, growing grass indoors.
Beginning the season with a new pitch
offers the greatest opportunity for the surface
to withstand the difficult environment it is
expected to perform within. Stadium pitches,
in general, have improved tremendously
over the past ten years, which is a credit
to all involved, including groundsmen,
researchers and manufacturers of specialist
turf maintenance equipment. I’m fortunate to
work alongside progressive agronomists and
the new generation of sports turf managers
and head groundsmen, who realise the
advantages of preparing a new pitch, rather
than repairing an old one.
So, what are the advantages of pitch
preparation rather than repair? When should
it start and how is it achieved?
Cultivating a pitch after Koroing
I feel it is important that
the groundsmen choose
materials that they want
to work with as, when
we’ve finished and left
the site, it is they who are
responsible for seeing
the pitch through to the
end of the season.
A consultant or the groundsman should
either prepare a specification or discuss
with a reputable contractor the work that is
required and when it can commence. The
specification will include a bill of quantities,
which will outline to the contractor what he
is expected to supply and what the club may
wish to supply themselves.
As a contractor, I feel it is important that
the groundsmen choose materials that they
want to work with as, when we’ve finished
and left the site, it is they who are responsible
for seeing the pitch through to the end of the
season.
Materials should be ordered and provision
made to store them safely away from the
elements as required. Bulk materials, such as
Fibresand or Fibrelastic, need to be ordered
in advance and a delivery time and date
agreed.
As soon as the club’s corporate department
has finished with the pitch and all coverings
are removed, the contractor should be on site
ready to commence work.
The existing pitch surface should be
stripped using a Koro TopMaker, a superb
Consolidation
piece of equipment that has revolutionised
the way pitches are renovated. The Koro
strips the entire surface, removing all organic
accumulations and leaving a clean, debrisfree
rootzone which can then be worked with
to produce the desired playing surface.
Initial cultivation can then commence to
break up any pans or layering which may be
present within the top 100mm of the pitch
profile. This work also serves as the ultimate
form of aeration as it redistributes particles
around the profile and allows any anaerobic
conditions to become oxygenated. Should
any soil conditioners, such as seaweed or
granulated lime stone and fertilisers, be
required, they should be applied at this stage
to ensure they are thoroughly incorporated in
43
to the vital top 100mm of rootzone.
Once initial cultivations are complete,
and dependent upon the specification, it
would be normal practice to apply new
rootzone material, which is often Fibresand
or Fibrelastic. This is intended to replenish
any material lost during the removal of the
surface. It is important to use a specially
adapted drop spreader, which is capable
of handling this type of material without
bridging or blocking as work progresses.
The evenly spread material can then be
integrated into the top 100mm by further
cultivation, normally with a rotary harrow. At
this stage, a visual inspection will dictate how
many passes with the cultivator are required
to produce an evenly blended rootzone. The
