“Let There Be Light” Follow Up

IMG_7315

There has been great idea exchange and feedback stemming from a recent article in SportsField Management “Let There Be Light”.  Thank you for that!! The article examines the introduction and use of supplemental light units for natural grass fields, back to its introduction from SGL in Holland.

What an enjoyable piece to put together! It stems from an “ah ha” moment during a recent visit to the UK.  A training ground was using the SGL light system for growth and recovery on high-use area on the training fields.  But wait?  Isn’t supplemental lighting just for stadiums with big roofs and shade?

NO!

When turfgrass growth slows in the fall/ winter/ spring, we concede the loss of growth to the time of the year.  The growth is slowed, yes by temperature in cold areas, but just as much by sun angle and day length.  8 hours of day length with the sun low on the horizon is not enough for grass to grow.  Thus is goes dormant.

And grasses themselves are grouped and described as “shade tolerant”.  Yet ultimately it really has nothing to do with shade.  “Shade tolerant” grasses simply require less light for maximum growth.  A great example is from the initial success of Latitude 36 bermudagrass in the transition zone.  In its first few year, Latitude has dramatically out performed other cold tolerant bermudagrass varieties in fall color and growth in the transition  zone.  Why does Latitude 36 sustain growth in the fall as temperatures fall and day length gets shorter?  Because it is a cold tolerant variety right?

Not all the case!  Latitude 36 is a very cold tolerant variety of bermudagrass. But via a new study from the USGA on “Development of Shade-Tolerant Bermudagrass Cultivars”, Latitude 36 now looks to be the most shade tolerant of all bermudas.  But again, its not just about shade… its about light requirement.  Latitude 36 stays strong with growth well into the fall because 1) yes, its a cold tolerant variety, BUT also 2) it requires less light to sustain growth.  As day length gets shorter and the sun angle gets lower in the sky through the fall, Latitude 36 is able to keep growing.

I reference the article “Pour Some Light On Me” from Dr. Karl Danneberger.  Dr. Dannenberger put all of these points into perspective magically several years ago.  THANK YOU for that!  Dr. Dannenberger references another study that caught my attention from Dr. B. Todd Bunnell and Dr. Bert McCarty on light requirement for TifEagle putting greens.  (Their study started in 2001, not 2004 as SportField Management referenced.  The GCSAA article was published August, 2004).  The article, “Sunlight requirements for ultradwarf bermudagrass greens” is tremendous.  I hope you enjoy it as much as I did!

Ultimately, turfgrass plants need light.  And supplemental light provides the opportunity for growth and recovery year round, where Mother Nature does not provide for year round growth from sunlight.  Hence, a training ground using supplemental light to promote growth and recover on high-traffic fields is not wasteful, but instead GENIUS!

That unique situation and the “ah ha” moment was a first, but there is no doubt that it will NOT be the last! With this type of innovation and technology, GrassCanTakeMore™!!!

Always Improving! University of Portland’s Merlo Field Universe Fraze Mow #2 Results

This week University of Portland’s Merlo Field became the first cool season turfgrass field in the United States to employ Universe Fraze Mowing for a second time.  In April, 2014, Field Manager Jordon Montgomery also was the first, as the first ever USA Field Manager to turn to the process for cool season turfgrass to remove:

70% poa annua population
– 1″ layer of thatch
– Reduce a thick layer of organic matter accumulated on the top of the sand based soil

The 2015 results of the Universe Fraze Mowing process were superb.

Poa Annua plants and seed have been removed, along with 2014’s thatch and organic build up to keep the field surface from becoming slick.  Now new ryegrass and Kentucky bluegrass seed will be sewed.  But even more importantly for durability and increased field use, the improved turfgrass varieties of RPR Ryegrass and HGT Kentucky bluegrass seeded last year following the Universe Fraze Mow can re-generate.  This will encourage the grasses to spread, ultimately increasing the tensile strength of the base surface to reduce divoting and wear.

2014 reduced the poa annua population from 70% to 20%.

The 1″ thatch layer was also removed along with the top of a thick organic layer.  The removal yielded a dramatically better playing surface.  The clean and re-generated surface is tight and strong, leading to nearly no divoting even when being used in the rain.  After 3 months of camps in Summer of 2014, a full men’s and women’s college schedule in the fall, and 13 spring matches, the field was nearly perfect when the 2015 Universe Fraze Mowing took place.

When Merlo Field is/ was in such excellent condition and the poa annua had been dramatically reduced, why Universe Fraze Mowing in 2015?

Simple.  Improvement.

From Field Manager Jordon Montgomery… “We want to continue to improve the playing surface while increasing use. The introduction Portland Timbers 2, the USL pro team calling Merlo Field home is an example of that.  All our home teams and events need the best playing surface we can provide while being environmentally and budget conscious.  That all leads to Universe Fraze Mowing”.

AMAZING EVOLUTION & Quick History!  Universe fraze mowing cool season turfgrass was first performed at Paris St-Germain’s Parc des Princes Stadium in July of 2013.  New Head Groundsman Jonathan Calderwood chose the bold method, previously only used in the United States on bermudagrass, to remove the poa annua plants in his pitch and leave behind the existing desirable Kentucky bluegrass and Ryegrass.

So yes… Universe Fraze Mowing is DIFFERENT than basic fraise mowing.  Fraise mowing was introduced in 1996 by Mr. Ko Rodenburg, Superintendent of Parks Maintenance in Rotterdam, Holland when he invited the KORO Field Topmaker.  Rodenburg invented the machine to clean the poa annua seed off the top of his playing fields and to encourage some basic regeneration.  Fraise mowing was born!

With the introduction of the KORO Universe® Rotor for the Field Topmaker in winter of 2012-2013; allowing stolons and rhizomes on spreading grasses to remain while removing organic, thatch, and weed seed; lead to Universe Fraze Mowing directly from this blog to Mr. Allen Reed and Mr. Miles Studhalter’s bermuda fields at FC Dallas.  See for details: Summary of a new concept; Fraze Mowing & Concept to Active Practice; Fraze Mowing Debuts at FC Dallas.   The use on bermudagrass had started, then Mr. Calderwood working with Mr. Simon Gumbrill from Campey Turf Care, took the lessons from bermudagrass and implemented them to cool season. Now Jordon Montgomery in Portland as taken it even further with repeated use.  AMAZING how it continues to evolve with creative minded Field Managers ready and willing to try to new things!  #GrassCanTakeMore!

Mizzou Sports Field Manager Josh McPherson’s Use of Universe Fraze Mowing Featured During Mizzou Soccer Match on SEC Network+

Columbia, MO; September 8, 2014: In June, University of Missouri Sports Field Manager Josh McPherson became the 1st SEC Sports Field Manager to utilize Universe fraze mowing. Friday night, Mr. McPherson was featured during the Mizzou soccer match on SEC Network.

Universe fraze mowing, a new cultivation practice adapted from an existing European practice, debuted in the United States in March, 2013.   Friday night, Mizzou Network featured Mr. McPherson and his decision to make Audrey J. Walton soccer field the 1st SEC field Universe mowed. Josh spoke of the reasoning for using the outside the box technique during the Mizzou v Northwestern soccer match on SEC Network+. See the feature here: http://youtu.be/sBwkOEWqu4c?list=UUsWz3SZVLdg3g51HSN4lPNA

 

Walton Field was one of five college soccer fields to be Universe fraze mowed in 2014, and one of 19 total fields in the US. Unique to Mr. McPherson’s use of the technique at Mizzou, Walton Field had the shortest regeneration window before it’s next use. Also unique, Walton Field was the 1st soccer field ever maintained by Universe fraze mowing developer Jerad Minnick. Minnick, President of Growing Innovations and creator of Growing Green Grass, is a graduate of Mizzou and alumni of Mizzou Athletic’s Sports Turf intern program.
