TURFGRASS TOPICS
PUYALLUP, WASHINGTON

PRESIDENT'S CORNER
By Mark Snyder
Welcome to our new members in the Northwest Turfgrass
Association!
1985 has been a record-breaking year for our Association;
culminating in one of the best-attended conferences in our history. It also marks a new beginning for turfgrass management
as the growing membership roll reflects the varied professional fields that exist in our Northwest community.
Those of us who have previously belonged to this professional
organization warmly welcome our new members. We are interested in your ideas. We are interested in you. How can we
help?
It has always been an instrumental part of the NTA to remain responsive to the needs of its members, since it was organized in 1948. Conducting timely research; promoting top
quality conference speakers and supporting each other in our
efforts to establish and maintain quality turf at our respective
'facilities.
A case in point that demonstrates this response is the well
attended split-educational sessions. In each group, specific information is presented that deals with particular conditions; be
they City Parks or golf courses, so that the membership as a
whole becomes better informed as to the varied issues in our
industry.
Another example is the Supplier Show. Begun just two conferences ago, the show is an open invitation to our commercial
friends to present their product lines to our members, in an environment that compliments everyone. This participation by the
suppliers and by our membership is genuinely appreciated by
the board and adds a lot to the success of our educational conference.
Since our association meets formally just once a year, the Turf
Topics, published in December, April and September, is our
best medium to communicate with each other. Hence, each
director will be contributing an article about his committee, beginning with this issue. If you have questions or want to suggest a change; contact us. The directors serve the membership
and their needs; from each geographical area of our Association.
To conclude, a growing, diversified membership is the very
) key to our future success. Our Association about your conference experience; invite others to join. We will all be glad that
you did!
Again, welcome. It is great to have you in the Northwest Turfgrass Association!

December 1985

NORTHWEST TURFGRASS
ASSOCIATION BOARD MEETING

The officers and directors of the Northwest Turfgrass Association met at the Western Washington Research and Extension Center on Monday, November 18, 1985. President Mark
Snyder had a full agenda and an excellent board meeting to get
the plans underway for this next year. The major goals of the
Association, as explained by President Snyder, was to increase
the membership, increase monetary income, high performance
by all committee chairmen, and develop a super conference for
1986 with a product and equipment show.
The following are brief reports from chairmen of various committees:
MEMBERSHIP COMMITTEE by Mike Kingsley. We are in
need of your help!! Our Association needs to continue its growth
in both quality and quantity, and you are the key to that growth.
The Association gains its strength from an active membership,
so to increase our strength we need to increase the number of
members.
To help you promote the Association and recruit new members, we are offering a reward. If you recruit a new member
between now and the annual Turfgrass Conference in Pasco,
we will reward you with the official NTA conference site golf
cap. These caps will not be for sale and are a very popular item.
So get yours the old fashioned way, EARN IT.
There will also be a valuable prize awarded to the person who
brings in the most new members, and if you are a supplier, you
can earn a free booth a next year's NTA trade show if you recruit 10 new members.
Your will find a membership application form in each of the
upcoming Turfgrass Topics, so please help get the good word
out. Your action will strengthen the NTA and help us better
serve our changing needs.
RESEARCH COMMITTEE by Dennis Pagni. At the November 18 board of directors meeting the board accepted recommendations of the Research and Scholarship Committee and
allocated $33,408.00 to Washington State University and Oregon State University. The board of directors allocated funds
for a set of sieves and shaker for Tom Cook at Oregon State
University, an Omnidata Polycorder and funds for completion
of a study of necrotic ring spot disease to Gary Chastagner, funds
for cultivar evaluation for Bill Johnston at WSU, and funds for
the support of a technical farm laborer for Stan Brauen, and
also funds for the purchase of a power plot sprayer to be used
at Farm 5. The funds for the sprayer were derived from money
earned from the supplier show at Rippling River. Thanks to all
you commercial suppliers for your support.
A reminder to NTA members that scholarships are available
to students pursuing degrees in turf management or related
fields. Please get the word out. Applications are available from
Dr. Goss at Puyallup. Scholarship applications must be sub(Continued on Page 4, Column I)

STRAIGHT TALK
ON FLUID LIME
By Bruce Remick
National Stone Association

Some farmers are switching over to fluid lime to solve their
soil acidity problems. Are they getting the most value for their
aglime dollar by doing so? In making the decision to go the fluid
lime route, they should keep these facts in mind:
1. The same factors which govern the capability of conventionally ground aglime to correct soil acidity also apply to the
fine limestone used to make fluid lime. That is, the effective
calcium carbonate equivalent of all ground limestone, whether
applied as ordinary aglime or as fine lime (-100 to -200 mesh)
in suspension will be determined by both quality (chemical purity and fineness) of the product, and the amount of calcium
carbonate applied. Increasing fineness may increase the rate at
which a particular limestone reacts with the soil, but it will not
increase the chemical purity of the product or the amount of
acidity it will neutralize. A 20-mesh limestone will neutralize
the same amount of acidity as will the same quantity of 100-mesh
limestone with the same calcium carbonate content. It will just
take longer.
2. Mixing limestone with water to make fluid lime does not
increase its effectiveness. It does not increase the amount of
acidity it will neutralize, and although the limestone in fluid

lime is very fine and reacts very fast, it reacts no faster than
if the same product were applied dry.
3. Fine lime breaks down in the soil more rapidly than regular dry aglime. Therefore, its residual effect on soil acidity tends
to be of shorter duration, making it necessary to apply fluid
lime more frequently, usually on an annual basis. This, plus
the fact that 50% or more of every fluid lime formulation is
water, makes fluid lime the higher cost alternative for liming
the soil.
Farmers should consult their county agricultural agents to determine the advisability of using fluid lime, and whether the
rates recommended are sufficient to remedy their soil acidity
problems.

HOW CAN I HELP
THE NORTHWEST
TURFGRASS ASSOCIATION
ATTAIN

ITS GOALS

IN THE

FUTURE?

By Gary Sayre, CGCS
Overtake Golf and Country Club
Medina, WA

Since the foundation of this organization in 1947, it has been
the aim to foster more and better research and to encourage
young men to enter the field of turfgrass management and to
seek higher education. The Northwest Turfgrass Association
through increased membership will be able to sponsor even better and more research investigations in the future as well as
financially assist qualified young men to seek and continue
studies in the universities and to encourage these young people
to return to the field of turfgrass management.
In 1962 the Northwest Turfgrass Association was granted an
exemption from the payment of income taxes under Section 501
[c] [3] of the Bureau of Internal Revenue code which states,
in fact, that the Northwest Turfgrass Association is a scientific
organization devoted to research and educational principles and
should not be required to pay income taxes on money granted
to the organization by individuals, or from dues collected by
the organization. It is well established today that the Association can receive grants of money from industry and any other
organization or person to be used for research and educational
purposes. This in itself can greatly help the Association make
outstanding contributions to all interested in better turf.
In 1986 you can help by setting aside some amount of money
to donate to the NTA which you can claim on your income tax
return as a deduction. You can also keep in mind that donations will be solicited through the mailing that comes out every
spring. Most donations are from $100 to $200, but there is no
limit, we just ask for your support. The state universities have
been cut back on legislative support and we now ask you to help
out.
Was your name on the contribution list last year, if not help
put it there this year. THANKS.

10. Were the hands on sessions worthwhile?
96% said yes and the same number wanted to see them
held again.
11. Would you participate if there was a park tour offered?
91% said yes. (We'll see if we can put one together!)
12. What topics would you like to see at the 1986 conference?
There were no clear-cut winners but here by top vote
getters are listed below:

13. What did you think about the suppliers show?
The suppliers show was a hit! Most of you felt the show
complimented the educational sessions. Most also wanted to see more equipment displayed.
14. Was the Wednesday night banquet worthwhile?
83% said yes but many qualified their opinions with comments. There is genuine concern about the cost of the
banquet. Many felt the entertainment was inappropriate.
A lot of people felt there was too much emphasis on golf
and that too much time was spent parading speakers in
front of the audience. In general people felt the speakers
should keep their remarks very brief and let everyone
enjoy themselves.
15. How did you like the golf competition/banquet?
There was no consensus on this one. Some liked it as
is, some wanted to change the format, some wanted more
competition on other days, and some wanted to drop it!
Most comments centered on how the competition
should be organized. Most golfers wanted to be paired
with players with similar handicaps.
The banquet was a sore point with some. As one person put it, "$15.00 for a chicken breast was ridiculous."
16. How did you like the site and facilities?
94% liked the location
88% liked the meeting rooms
84% liked the lodging accommodations
69% felt the banquet service was good
63% felt the food service was fair to poor
55% felt the food was fair to poor

It's hard to tell the difference between goosegrass and late-germinating
crabgrass.
But if you treat your turf with Chipco RONSTAR' G
herbicide, it makes no difference.
RONSTAR gives excellent control of both, season-long...
and it's convenient to use, because there's no leaching problem, no root pruning, and no problems with ornamental
plantings.

Summary
The survey indicates we have a more diverse group than in
the past. Our non-golf membership is increasing. We have a
good cross section of ages, experience, and educational backgrounds. Turf is the main interest of the group but related areas
are also important. For the most part attendees are happy with
the format, subject matter, and level of the conference. The suppliers show is a desirable part of the conference. Golf is frustrating for everyone but the winners. Most people would like
cheaper lodging and better food.
Thanks to those of you who responded to this survey. If you
didn't respond and you feel your opinions don't match the survey results, make sure you fill out next year's evaluation!
COMMERCIAL EVENT-TRADE SHOW by Bill Campbell. A
completed packet of information was presented to each of the
directors showing specifically what will be included in the commercial event for 1986. Bill Campbell had a complete list of
prospective exhibitors and urged the directors to go to work
on these people in their areas to fill up the trade show as quickly as possible. The goals for 1986 will be approximately 50
booths which Bill Campbell feels we can achieve without great
difficulty. In general, essentially the same format as 1985 will
be followed.
FINANCE COMMITTEE by Gene Howe. Gene Howe will

his committee are finalizing their recommendations for three
new directors for 1986. Anyone who has a strong desire to become a director of the Association can feel free to volunteer
your services to Gary Sayre and his committee.

GREEN SLICK AS GLASS?
LOF Puts Old Expression

CREDIT: Divots

to the Test

R O N A L D F R E A M DESIGN GROUP, LTD.
GOLF COURSE ARCHITECTURE

Every golfer knows what it means when a green is 'slicker
than glass." It means trouble. But Golf Digest, with a little help
from Libbey-Owens-Ford Co., tried to put some precision in
the golfer's cliche by comparing glass and grass mathematically.
For its June issue, the magazine commissioned a series of
tests on a variety of surfaces: marble ("faster than a marble
staircase"), pavement ("like putting on concrete"), a billiard
table ("smoother than a billiard table"), and a tub of molasses
("slower than molasses in January").
To get comparative speed figures for its tongue-in-cheek test,
Golf Digest used a Stimpmeter—a device designed to release
a rolling golf ball so that the distance it rolls indicates the
"speed" of the surface. Most golf greens allow the ball to roll
6 to 8 feet, the magazine said, but some very fast greens might
register up to 14 on the Stimpmeter.
So, how fast is glass versus grass?
To find out, Golf Digest contacted LOF's corporate headquarters in Toledo, and after some consultation, the company's
management decided there was no harm in the project and allowed the test to take place on a huge sheet of glass at its Rossford plant.
An LOF employee, Leonard Klaege, performed the Stimpmeter test, and the magazine recorded the result:
"Reading: 468.7. Summary: For this report, we rely on our
correspondent, Mel Barger, who supervised the test " The
ball traveled fast out of the Stimpmeter and did not appear to
be slowing down much by the time it reached the edge of our
26 foot, 8 inch piece of glass. According to our stopwatches,
the ball traveled this distance in 5.001 seconds, so you can relate that to the speed of other surfaces. We also noticed that
golf balls don't roll smoothly on glass. The dimples on the balls
apparently make them sort of bounce along.
The magazine concluded that molasses in January is indeed
slow. The ball traveled only two inches. "What's appealing
about the surface, however, is it putts so true."
The Magazine's "scientific" findings were clouded somewhat by circumstances.
The 68.5 reading for a marble staircase, for example, was
expurgated to keep the ball from rolling through a 300-yearold Chinese vase.
The billiard table only rated 5.9 because "the Stimpmeter
scored a Titleist 3 in the corner pocket."
And the sloping of the New Jersey Turnpike could have accounted for its high reading of 17,462. "Following in a car we
observed the ball accelerate near the Newark, NJ, exit on the
turnpike, then roll steadily to a point opposite several Elizabeth,
NJ, chemical plants, where it passed through a patch of lavender mist and disintegrated."
The results of the tests, the magazine said, "suggest that the
poetry of putting and the science of speedometry cannot be
mixed."
EDITOR'S NOTE: Your editor tested a linoleum hallway at
Kalkus Hall at the Western Washington Research and Extension Center at Puyallup, Washington, and had a reproducible
99 feet. The Top Flight No. 6 golf ball was found on the Nixon
Par 3 Golf Course at San Clemente, California, in April 1973.

AMERICAN SOCIETY
OF AGRONOMY MEETINGS
HELD IN CHICAGO
Roy L. Goss

The American Society of Agronomy annual meetings were
held in Chicago, Illinois on December 1-5, 1985. Over 2,000
agronomists from around the world convened to present scientific papers and symposia and to exchange scientific information in all areas of crop production and soil science including
turfgrass management.
For many years we have had the Division C5-Turfgrass as
a part of the ASA meetings, and in 1985 there were more than
72 research papers given as well as one complete afternoon
devoted to a symposium on water. The following is a very brief
summary of some of the papers presented that have meaning
and impact on turfgrass management programs in the Pacific
Northwest.
EVALUATION OF CULTIVATION TECHNIQUES
FOR SOIL COMPACTION
J.F. Barber from Nebraska and R.N. Carrow from the
University of Georgia reported that core cultivation outperforms slicing with respect to soil responses and core cultivation significantly changed the oxygen diffusion rate. Their
results indicated that plants react quickly to compaction stress
but are slow to recover from it.
EFFECTS OF CULTIVATION TREATMENT IN
PRE EMERGENCE HERBICIDE
ON CRABGRASS INFESTATIONS
Brannum and Reike of Michigan State University reported
that aerification and vertical mowing immediately following application of three pre emergence herbicides, benefin, bensulide
and DCPA, had no effect upon their efficacy in controlling crabgrass. This is good information since it indicates that cultivation operations can be safely carried out without significantly
reducing annual bluegrass control.
SEED PRIMING AND ITS EFFECTS ON KENTUCKY
BLUEGRASS/PERENNIAL RYEGRASS MIXTURES
J.L. Brede, et al. from Oklahoma State University reported
that Kentucky bluegrass and turftype perennial ryegrasses could
be planted together and result in germination at the same time
if the Kentucky bluegrass seed was primed (osmoconditioned)
before planting. The priming agents they tested were sodium
chloride, potassium nitrate, and polyethylene glycol (PEG
8000). Their results indicated that they could induce bluegrass
seeds to emerge a full three days ahead of non-primed seed.
They also observed field survival of bluegrass seed 27% greater
than untreated seed.
EFFECTS OF SOIL TEMPERATURE AND MOISTURE ON
THE DEGRADATION RATE OF DACTHAL (DCPA)
Choi and Fermanian from the University of Illinois, using
five temperature ranges of 10-35 ° C (50-95 ° F) of soil temperature, found the following results. Temperatures of 77 to 86°
F resulted in the fastest degradation rate. Only 9% of the initial DCPA remained in the soil five weeks after treatment. Temperatures of 50 to 59° F showed very slow degradation rates.
Seventy percent of the initial DCPA remained in the soil five
weeks after treatment. This information will provide guidelines
(Continued on Page 10, Column I)

(Continued from Page 9, Column 2)
for individuals and commercial applicators with respect to the
efficacy of dacthal and local weather conditions.
INFLUENCE OF SPRING MEFLUIDIDE APPLICATION ON
THE CARBOHYDRATE STATUS OF POA ANNUA
Cooper, et al. from Ohio State University reported on their
tests with mefluidide (Embark) at rates of 0.06, 0.13, and 0.19
lb a.i. per acre. They reported that Embark suppressed seedheads of Poa annua and significantly increased the reducing
sugar content of roots. They found 4.9% sugar in the roots of
treated plants as compared to 1.2% in untreated plants when
the untreated plants were seeding profusely.
These are indicators that in addition to growth inhibition some
of the plant growth regulators have beneficial side effects.
In addition to all of the papers presented, there were numerous poster sessions and one that will be familiar to the Pacific
Northwest is one presented by Dr. Jeff Nus who was a former
Research Associate here at the Western Washington Research
and Extension Center at Puyallup. Jeff is currently in charge
of the turfgrass research and teaching programs at Kansas State
University. His poster display was entitled 'Evaluating turfgrass response to water stress using moisture release curves."
The authors were J.L. Nus, S.E. Brauen and R.L. Goss.
