Take A Closer Look

things are so familiar to us that we do not take the time to stop and look
closely. Our update this week features an exercise in making observations and a
closer look at the USGA Course Consulting Service.
Two Varieties – Many Differences.
a recent USGA Course Consulting visit, the superintendent and I had the
occasion to take a cup cutter sized sample from a Tifdwarf putting green and a MiniVerde
putting green on his golf course. We washed off all the sand rootzone and
topdressing and spent the better part of an hour carefully observing the
differences between these two varieties. When viewed from a unique perspective
(all plant material and no soil), the differences were startling. Interestingly,
crew members began gathering and they too were intrigued by the samples.
two photographs were taken after washing and served as the basis for our
observations. When we studied the samples, we asked many questions:
one had a deeper root system?
one or the other seem to have more growing points near the surface?
was the grass different on the surface?
would we see if we looked under a magnifying lens?
comparing and contrasting the samples, we asked the most important question: Given the differences observed, how should
this impact the management protocol?

Take a Look at the USGA Course
USGA Course Consulting Service has undergone numerous changes recently. After
60 years, the name Turf Advisory Service was retired and changed to Course
Consulting Service. In addition to our normal half day and full day general
assessment visits, we have added a selection of visits focusing on the
more information on our Course Consulting Service and the visits we now offer,
please visit: USGA
Course Consulting Service . We would welcome the opportunity to come to
your course this year. Contact us soon as our early payment discount ends on
May 15, 2014.
