The pursuit of speed puts the single greatest pressure on
greenkeepers to enhance performance of greens. Greenkeepers need to
look for new techniques to sustainably manage faster surfaces more
effectively, as well as focussing on the quality of ball roll and,
most crucially, the trueness of the surface, according to STRI
agronomist, Henry Bechelet.
At Turf Science Live, organised by Syngenta and Everris
(formerly named Scotts) at The Belfry last month, he demonstrated
that Primo Maxx treated greens cut at 4mm and rolled with a turf
iron could run faster and smoother than when cut at 3mm
alone.

"Over recent years greenkeepers have been cutting tighter and
tighter to get the speed up, but that can put real stress on the
plant and make it more susceptible to all sorts of problems. When
you intensify any part of the management it almost inevitably
creates issues that require extra inputs to resolve," reported Mr
Bechelet (above).
Co-presenting the demonstration, Ed Carter of Everris, added: "The beauty of Primo
Maxx is that it can relieve pressure at almost every point of turf
surface management. When it's included in the programme it may be
possible to ease back on other inputs and activities, which can be
a real benefit for managing turf health.
"Not only does Primo Maxx improve the turf plants' ability to
withstand the impact of stress, through improved rooting and
physiological effects, but it will also enhance turf playing
quality. It also gives greater flexibility and cost savings for
cutting and turf management," he advised. Mr Carter added that an
Everris liquid fertilizer should always be included in the tank mix
to promote healthy turf quality, as demonstrated on the Turf
Science Live trial.
Henry Bechelet also urged greenkeepers to look at other
techniques that can take stress off the plant, including raising
cutting height; an increase from 3mm to 4mm means 33% more leaf
area and the potential for plants to look after themselves more
healthily. Rolling, for example, could alleviate the daily cutting
regime for some clubs, with positive implications for cost and time
saving.

"Producing a denser surface from healthier plants enables the ball
to roll across the top rather than sinking in, which can in itself
increase speed without detriment to health - and it's more
sustainable in the long term," he added. STRI experience in
monitoring and managing daily greens' performance at Major golf
tournaments and through the STRI Programme has shown that even
slightly raising the cutting height can help improve the smoothness
and trueness of the putting surface.
Mr Bechelet believes the key to implementing any change is being
able to quantify what is happening now, and then being able to
demonstrate the result of any actions. "Being able to measure
change is vital to combat preconceptions of players and
management," he said. "If you are going to raise the cutting
height, for example, you have to show that the greens are still
running as fast. The STRI Trueness Meter™ is designed to give the
essential validation and help progressively assess future
improvements in greens quality," he advised.
