MEETING WITH MEMBERSHIP TO DISCUSS GOLF COURSE MAINTENANCE


On January 22nd a meeting was held in the Forest Creek Clubhouse for the purpose of discussing the Forest Creek golf course maintenance programs for 2014. The managers  from that department, Bill Patton, Graham Purcell (South),  and Chris Noll (North)  were there along  with Jim Lewis, green committee chairman and 65 members of Forest Creek.  This “Pizza with Patton” night was an opportunity for the Golf Course Maintenance Department to discuss with the membership the plans and improvement  goals for 2014. Bill Patton presented an outline of plans and  also included responses to several questions that had been provided in advance.  A question and answer session followed. The following summarizes those comments and answers.

 

PIZZA WITH PATTON COMMENTS

The critical element of the planning for operations in 2014 is the 2014 Golf Course Maintenance budget.  The overall budget has been increased by  $320,000 for 2014 over last year’s 2013 budget.  The labor budget for 2014 has increased to $1,068,000 from $903,508 in 2013.  Those percentages of labor to overall budget are in line with normal percentages  in the golf course industry.  One half of our budget increase is going to labor costs.  The non-labor budget increases are going into more money for chemicals, more money for fertilizers, and more money for equipment repair.  We believe that these budget increases are what we need  to produce the conditions that you expect .

We  are reorganizing our staff in several ways to improve performance.  We have added a second assistant superintendent  on  each golf course. These are college trained individuals who have both graduated from the Sandhills Community College program.  One worked as a coop student at Forest Creek while he attended school.  The other individual had been working as an assistant at Secession Golf Club before moving back to Pinehurst to get married.  These additional assistants will improve the coaching and supervision of our staff.   We are also keeping more staff on through the winter to accomplish special projects and we have upgraded the skill level in our new hires by paying a slightly higher wage.

The capital budget  also a reflects our efforts  to upgrade our facilities.  Two programs planned for this year are repairs to the decking and rails of  our bridges and repairs to our cart paths by repaving areas around tees and greens and on steep slopes.  Whether these two programs happen is a function of cash flow to the club.  The profits which the club derives from the 2014 US Open have been earmarked for capital improvements and our programs are dependent on cash flow from this event.  The third leg of our 2014 capital program is the purchase of new equipment.

There is a commitment to go forward with a program of regularly replacing our golf course maintenance equipment.  This program would make a regular purchase of $150,000 of golf course maintenance equipment every year.  As a general rule one golf course requires  $500,000 of maintenance equipment to be successful.  Two golf courses through a sharing of equipment should require the lower number of $750,000.  Most golf course maintenance equipment has a useful life of five years.  Therefore a program which replaces $750,000 worth of equipment with $150,000 of equipment every year should be successful.  Problems developed at Forest Creek because we did not follow this program of replacing equipment every year and instead skipped equipment purchases in five out of six years from 2006 through 2011.  The last two years have seen improvement through purchasing $250,000 in 2012 and $140,000 in 2013. During the last year we have been able to repair many pieces of equipment by opening up our credit lines with our equipment suppliers that were closed during our hard times while we transitioned to FCI.

One of the most important goals for improving conditions on the golf courses for 2014 is a commitment to keeping the golf courses firmer and faster.  Tools which we will use to accomplish this goal are aerification and topdressing.  Last year we began a new program of intensively core aerifying the tees, the  fairways, and the green surrounds followed with topdressing. This effort was aimed at thatch removal, something that had been neglected for the last several years.   We plan to continue that program this year and have scheduled each golf course to be closed for two weeks at a time this summer.  We will aggressively aerify, then verticut  and finally topdress with sand to promote a firmer, healthier, and smoother bermudagrass playing surface. The South golf course has more thatch because of the type of bermudagrass  grown there as well as many years of overseeding with ryegrass.  If we can remove the thatch as well as promote its microbial breakdown with topdressing then we can have a firmer and hopefully drier playing surface in 2014.

Thatch holds water and its removal will promote drier conditions.  Last year our records show that we had 61.75 inches of rain at our maintenance facility.  We usually notice variation in our gauges from one side of the golf course to the other.  The state research station in Jackson Springs recorded 71.11 inches in 2013. The golf courses were wetter last year at times than we would like them to be.  Some of that was due to rainfall that was 50% higher than normal.  We believe that by removing thatch the golf courses will dry more quickly.

The problems that we had with goosegrass contamination on the South golf course in 2013 was a function of poor application and poor  performance of preemergent herbicides.  We applied Specticle and Ronstar to the North golf course and had a good result.  Because the South was overseeded with ryegrass we were unable to use those two products and relied on our traditional herbicide of Barricade.  Its performance in many areas was unacceptable and a serious problem.  Because we did not overseed this year on the South we will be able to use Ronstar on both golf courses.  Ronstar is much better at preventing goosegrass than is Barricade.

At the suggestion of the USGA green section we will use a different aerifier in the fairways this summer which will be less disruptive to playing conditions.  Our goal will be to loosen the soil, promote air exchange while not creating unacceptable turf conditions.  We want to return the golf holes in good condition at the end of the two weeks that we have closed.

We have done the most extensive prevention program for “spring dead spot” this year that we have ever done at Forest Creek.   We applied “tebuconazole” to all the fairways and tees on the South golf course and  to typical problem areas on the North golf course. “Spring dead spot” is a fungal disease of bermudagrass roots which typically occurs in fall but only becomes visible in the spring.  We will not know how effective our prevention program has been until spring.

We have several regrets about what happened in 2013.  The outbreak of goosegrass was devastating and we regret not using different herbicdes and applying them more carefully. We regret not overseeding the driving range on our regular schedule of between 9/15 and 10/15.  We waited until after the Member/Pro tournament which pushed us into November.  With this year’s early hard freezes that was too late  to have the ryegrass established going into winter. We also regret that  we did not communicate  effectively to the membership about why we were closing  the golf courses for aerification and why this disruption  was necessary.  We did not explain the ultimate benefits that it was intended to produce.  We felt that we had put this information on our blog but the message did not get out.  In the future we want to do a better job of directing people to the blog for information.

A major goal for 2014 is to do more golf course maintenance on the weekends to promote better playing conditions on the weekends.  We will schedule more people to work weekends and we will do more mowing.  We have spent the winter rehabilitating two older fairway mowers so that we can mow more often.  We will begin walk mowing the smaller tees on both golf courses in 2014.  We will also begin walk mowing the approach cut outside and around the greens to reduce compaction and wear between the greens and the bunkers this year. We want to mow our tees and fairways  more often and with sharper mowers in 2014.  We will try to handrake greenside bunkers when we are mowing the greens to reduce the problems with our mechanical trap rakes.  We will continue to remove asphalt cart paths where they are compromised by tree roots and replace that asphalt with native sand.  We will install more drains in our sand cart paths to stabilize them and also experiment with some spray-on polymer products that will stabilize the sand.

 We have begun a leveling and topdressing program on the left side of the driving range.  We will continue this effort and also install herringbone drainage if necessary. We have constructed  a new cart path on the left side of the driving range which will enable golfers to get to the practice area at the back of the driving range without going through the maintenance facility.  We hope to continue to upgrade that area  with improved accessibility and improved turf conditions.  We have found that this practice area at the back of the driving range is being used more and we wish to further promote its use.   We plan to pump bunkers that continue to hold water after rainfall and to work on the internal drainage of these same bunkers. We have already repaired the internal drainage in bunkers  on holes 9,15,16, and 17 on the north golf course this winter.  We have rebuilt the bunker  faces in the front bunker on 17 south and we have also changed the bunker sand in this bunker.  Due to concerns about  the wire grass plants on the bunker faces on the North golf course, we will communicate with the Fazio Golf Design  to get their input on these features and follow their directives.

There is an ongoing program of tree removal where the trees are causing agronomic problems.  We have rebuilt the championship tee on 18 south and sodded it with “zeon” zoysia grass.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     We have leveled the short tee on 2 south. There are plans to address drainage issues on the tees of 15 north and 12 north with topdressing and internal drainage.   There are plans  to add  a new tee on 16 south in front of and below the existing Long tee.  The completion of these plans on 16 are depends on the availability of capital funds later in the year.

It is our general practice to mow the greens every day when the weather is suitable for their growth.  Sometimes mowing is done when they are not growing to simply remove the brown winter-burned leaf tips. Sometimes in the summer when the greens are stressed because of heat we will skip mowing. This winter has been unusual and we have been mowing more than usual; the temperatures have fluctuated widely with extreme lows followed by remarkable warming.  Cups are not scheduled for changing every day.  However,  during  the seasons of the year when play is busy, we will change cups every day.  As a rule of thumb, we use 75 rounds as a threshold for changing but will not go very many days without changing.  We are now committed to changing cups on Friday, Saturday and Sunday regardless of the number of rounds played when we are in season.  Our practice in regards to the “cleanup” pass around the greens is different from what was done historically in our industry, but it is commonly done this way now.  We mow the “cleanup” pass around the edge of the green with a different mower set at a slightly higher height of cut which is operated by a veteran skilled operator. This cleanup is usually mowed every other day.  This pass around the edge of the green can become worn and compacted if done every day.  When the morning dew pattern shows that we have not made this pass it is not usually a mistake by the greensmower.   However if you can look down and see a difference in the grass heights then we have gone too long between cleanups and have made a mistake.

We are seeking feedback on the practice of painting fairways.  It has not been what we expected.  Early dormancy and harsh weather has made for a different experience industry wide with painting than in past years.  We purchased sufficient paint in the fall to apply 10 gallons of paint to the tees and fairways of the South golf course and planned three separate applications of 5 gallons, 3 gallons, and finally 2 gallons.  We used all our paint by December 1 to produce an acceptable look which is now fading.  The industry recommendation is now to start with 8 gallons and not paint as early as they had previously recommended. 

 Efforts are being expended this winter to refine our pin position matrixes and to coordinate tee position placement with those pin depths to give variety on par three golf holes. We are edging golf holes and edging around tress to give defined lines to the golf courses.  We are also trying to manage the turf edges to maintain playability so that an errant shot can be found and played.  This involves making sure that the blowers do not pile pine straw up in areas as well as limbing up the holly trees that are in play so that a golf ball can be found underneath them.

We want our golf course to be a “player’s “ golf course and we will try to achieve firm and fast conditions.  We will not manage for color.  We may not always achieve that goal but that is what we strive for.

We realize that bunkers are a priority and that we have to work at getting them better.  The trap rake operaters have to be careful  coming out of the bunkers and also not ride too high on the edges.  These efforts are part of ongoing golf course maintenance.  We constantly coach and instruct our employees how to do this properly.  We are hopeful that more handraking of bunker and changing the rakes on the riding trap rakes more often will solve some of this. The plan is to have the greensmowers hand rake all greenside bunkers as they mow their set of greens.

The maintenance employees are trained to get out of the way of golfers.  This is a constant educational process for us.  We have 25 core employees who work throughout the year.  We will add 20 more throughout the season.  Ten will be brought on for the March through October season and ten more will come on as summer help or as part time interns or coop students from Sandhills Community College.  We are constantly training these new employees throughout the season.

Irrigation for Forest Creek’s two golf courses is controlled by one central computer so we have to be careful with watering because often we will get rainfall on one part of the property and not another.  We adjust irrigation through field satellite controllers so that different areas get different amounts of irrigation based on their topography and their soil types.  We strive to keep the grass healthy with sufficient irrigation but without over watering.  Sometimes mistakes are made with heads sticking on and control systems not working.  There are more sophisticated systems available with more opportunity for control of different areas through multiple weather stations, but these are expensive.

The management philosophy of  “firm and fast “ also embraces having playable fairways.  The mowing height of our bermudagrass  fairways “ in season”  is .045 inches.  We believe that this allows the ball to roll while also providing sufficient grass under the ball for it to be playable.  Firmness will be managed with moisture control, thatch control, and frequent mowing with sharply adjusted mowers.

The conversion of either golf course at Forest Creek to ultradwarf bermudagrass is not planned at this time.  We have planted two bermuda grass greens to experiment with  ultradwarf bermudagrass and to learn  the different cultural rquirements that these grasses have.  The advantage of ultradwarf greens is in the summer when you can have firm greens.  We will almost always be soft in July and August with Crenshaw bentgrass greens.  Normally we should recover and begin to firm back up during September. This year the most difficult weather for Bentgrass was in September and the greens were late to firm up.  Firmness is a function of a healthy growing root system and soil that contains the proper mix of organic and mineral matter.  We believe that the greens are still performing properly with good internal drainage and good greensmix.  There are problems at the edges of the greens with bermuda grass encroachment and there has been some discussion  about resodding those edges with one of the newer bermuda grass hybrids such as “tifgrand”.   Most of the problems with the greens in the summer are heat related.  We experience difficult weather in which to grow bentgrass .  Bentgrass grows roots throughout the fall and spring, but when the hot weather arrives in summer the bentgrass roots recede.  The plant will feed on its own roots to such an extent  that by the end of summer the roots  are very shallow.  This diminished root mass allows the soil to become softer.

Deer have become a larger problem on the golf courses with the eating of ornamentals. They are more numerous than ever but they cause little damage to the golf course itself.  We have had some success controlling the geese with the use of dogs, a motor boat and string lines.

BERMUDAGRASS IN WINTER

The past week has brought low temperatures to the eastern United States that have not been experienced in decades.  This cold front described as a  "polar vortex" has brought overnight lows in Moore County into the single digits.  When we experience low temperatures like these we worry about injury to our Bermuda Grass.  This low temperature injury is known as "winterkill" and it is different from "spring dead spot" which  is caused by certain root fungi during the fall and spring.  The severity of "spring dead spot" is influenced by winter weather while "winterkill" is totally the result of severe winter weather. In the upper transition zone (Kentucky,Virginia, Oklahoma) "winterkill" is reported as a once every five year occurrence.  In the Sandhills of North Carolina it is seldom experienced.  However our new "ultradwarf" Bermuda grass varieties are thought to be more susceptible to cold temperature injury and this is the first time we have seen temperatures this low since we began converting our bentgrass greens in the Carolinas to "ultradwarf" Bermuda. It should be noted that our traditional hybrid Bermuda grasees used in the fairways can suffer "winterkill" but they are thought to be hardier and less susceptible to injury than the "ultradwarf" bermuda grass used on our two new greens.

University research has been done on ways to protect "ultradwarf" Bermuda greens from "winterkill".  The consensus recommendation is that our first line of defense is the placement of geotextile covers over the"ultradwarf" grass. There are numerous options available in different fabrics from different manufacturers. These covers are usually custom cut and sewn for each green.  Greens in the shade and greens facing north are more susceptible to injury so sometimes these greens are covered when others are not.  The rule of thumb for covering is you should cover when the weather forecast predicts lows of 25 degrees F or lower for two or more consecutive nights along with daily highs of less than 50 degrees F. For our two new Bermuda grass greens we bought covers manufactured in Canada and and sold under the trade name  "Evergreen".

Historically, covering greens in the South to prevent winter injury dates back to the 1920's.  As southern greenkeepers struggled to find turf for use on their greens they found common bermudagrass to be the only grass which would survive the summer.  However getting that common Bermuda to survive the winter was difficult.  These early greenkeepers would establish a winter green of poa annua, ryegrass, or redtop in front of their summer green and then cover the summer green with pine straw for the winter.  (USGA Green Section Record Volume 1 No. 12 December 16,1921.)

Because of the intense cold we experienced here this week we decided  to try an old practice and add a pine straw blanket on top of our geotextile covers.  Other golf courses throughout the south have done this also. This was far easier for us than most golf courses since we only have two Bermuda greens.  The process of placing covers on the greens for cold weather and removing these covers when it becomes warmer is labor intensive.  For 18 greens the typical labor force is 4-6 people for 4-6 hours. Often it is windy because we are installing covers as a windy cold front moves in. At left is a picture showing our chipping green with its geotextile cover and pine straw being removed.

We do no not have any way of providing additional protection in these cold temperatures for our Bermuda fairways. We took steps in the fall to prepare the turf for winter. We limited nitrogen fertilizer applications, we applied potassium and we raised our height of cut. Factors which can contribute to fairway Bermuda injury in the winter are shade, traffic, poor drainage and moisture deficiency leading to winter dessication.  We would like to think that we have done all that we can do to protect our turf for winter.  As the turf comes out of dormancy this spring we will monitor our golf course and do everything we can to have healthy turf this spring.

BUNKERS, SAND, AND RAKES

Bunkers on a golf course can cause both pleasure and pain. When bunkers are properly designed and properly placed, they can transform a dull and boring golf hole into a challenging and beautiful golf hole. When they are poorly built they can be expensive to maintain and difficult to play out of.  We must remember however that they are  hazards.  Donald Ross once said; " There is no such thing as a misplaced bunker. Regardless of where the bunker may be, it is the business of the player to avoid it."




At Forest Creek we have different bunker styles throughout the golf courses.  The South golf course has both formal bunkers  and waste bunkers.  These formal bunkers were built with internal drainage and were filled with a sand blended for golf course bunkers in Lilesville, N.C. called the Bonsal Bunker Blend.  The bunkers on the North Golf course have a rougher and more natural feel and are all played as waste bunkers. Most of these bunkers on the North were carved out of the original sand in the places where they are located.  Where the sand is not original, it is native sand hauled from other places on the golf course site. Some have internal drainage and many do not.



Unfortunately  the quality of bunkers on golf courses is a subject of too much debate. Bunkers are judged on their design, their location, their drainage, the type of sand they contain, and the manner in which they are maintained.  Sand particle size and shape is analyzed. Sand depth and softness is measured. Drainage is emphasized so that play will never be interrupted.  Sand purity is sought with sand free of silt, clay, organic matter and rocks. Gravel in these bunkers occurs naturally and also surfaces from drain lines. Some golfers prefer that the sand be maintained in a firm condition while other golfers want softer sand. Golfers want sand of a uniform depth.


Golf architects dictate the style of bunkering. Some prefer high flashed sand while others want the sand to be flat with grassy banks coming down to the sand. Different styles require different maintenance practices. The management of a golf course must decide on the intensity of the bunker maintenance they desire. Will bunkers be raked every day? Will three days a week be sufficient? Will mechanical rakes be used or will the bunkers be hand raked?  When the bunkers fail to drain should they be pumped?  When there is gravel in a bunker must it be removed?  All these decisions effect how much bunker maintenance will cost.



The USGA Green Section reports; "As the Green Section agronomists travel the country and visit courses of all budget levels, the most common complaints from golfers involve bunkers. Depth of sand, "fried-egg" lies, lack of consistency, and even varying moisture levels are all sources of dissatisfaction. Many golfers believe they are entitled to a certain quality of lie in a bunker and that anything less is a sign of poor maintenance or bad sand, and usually both.  Unlike the other hazards on the course, bunkers now have to be "fair"." (USGA Green Section Record July-August 2008)  It has also been reported by the USGA Green Section; "American golfers have developed an unreasonable expectation for nothing less than a perfect lie in a bunker and equally unreasonable demandas for absolute consistency of playing conditions between bunkers. Bunkers are hazards to be avoided, yet many mid-to-high-end courses in the United States spend as much or more money to maintain bunkers than their putting greens." (USGA Green Section Record September 2010)  Obviously, since intensive bunker maintenance is expensive, golf courses must decide how much of the budget should be allocated to bunker maintenance and how important is a perfect lie in a bunker.

Another question about bunkers involves the placement of rakes. Where and in what direction they are placed is the question.  The USGA recommends placing rakes outside the bunker and parallel to the line of play, preferably along the outer edge of the bunker, so that it will reduce the overall chance of the rake coming into play, while also eliminating the rake's possible influence on a ball within the bunker.  It is also recommended that a low side (or sides if multiple rakes are needed for a large bunker) be selected. Climbing in and out of  the high sides of bunker causes major damage to the bunker face and surrounding sod.  Rake placement (in or out of the bunker) effects golf maintenance efficiency because the rakes must be moved to perform mowing or raking.  At different times of the year the place to put the rakes for efficiency can change.

When buying sand for golf course bunkers there are many options now available.  There is a pure white sand from Spruce Pine N.C. that is a byproduct of mica mining.  This sand is used at Augusta National and at many golf course throughout the Carolinas.  In the Sandhills of North Carolina where there are many commercial sand mining operations we have several different sbunker sand options.  We now have "cracked " sand available to us from sand pits in Hoffman N.C. A "cracking" machine is moved around to various sand pits to do this work. This sand is used because it will stay up on steep slopes.  Because it is angular and not round it creates a steeper angle of repose.  Put simply, it will not slide as easily down the slope.  We used this sand in the bunkers at the new chipping green. When purchasing sand the cost of shipping is a large part of the price. Local sand is always less expensive.

Golf course bunkers are much more than a sandy hazard to be avoided.  They are constructed to look natural and drain quickly.  The sand within them can be natural or a product of mining and engineering processes.  They are expected to be fair and nearly perfect. They are expensive to maintain and are a major element of golf course maintenance budgets.  At Forest Creek we have developed standards and guidelines for maintenance practices.  There is a specific section which deals with bunkers. We do not always achieve the standards which are outlined there but we are always working on the bunkers in an effort to meet those guidelines. This winter we have been working on drainage issues and will begin another project to remove gravel.  We will be working on the bunker on 17 South to eliminate the bunker faces which have fallen and will be adding our new cracked sand.

FALL AND WINTER PROJECTS

Fall weather creates the opportunity for the golf course maintenance staff to take on special projects to improve the golf courses.  For the last several months we have been concentrating on  maintaining the golf courses.  Cooler weather has slowed the growth of the grasses on the golf courses and we no longer have mowing grass as our dominant activity.  We now have time fix all the troublesome areas on the golf courses with drainage and new construction. This is our chance to do the things which will make the golf courses better next year.

During this past year we were able to plant a herb garden outside the kitchen.  We also worked on bunker drainage and rock removal from the bunkers.  We created a new chipping green area with Miniverde Ultradwarf Bermuda.  We converted another green in a residential area to Champion Ultradwarf Bermuda. We removed asphalt cart paths which had been compromised by tree roots and replaced the asphalt with sand.  We eliminated seven out of play wastebunkers. We leveled tees.

Already this fall we have several projects underway.  We enlarged and renovated the putting green on Wellington Drive.  We regraded and enlarged the  back tee on 18 South and resodded it with Zeon Zoysia. We have undertaken a program to level and improve drainage on the left driving range tee.  We have begun drainage improvements in the bunkers on the North

We have many other projects planned, including a new access path to the back of the driving range and enhancements to that "back of the range" practice area.  We plan to continue removing asphalt cart paths and improving the sand paths with more sand and drainage. We want to remove tress which are causing agronomic problems.  Repairs to our cart bridges with new decking and railings is in the planning stage.  We will run out of winter before we run out of projects.
 

COLORING FAIRWAYS

One of the trends in  the southeastern United States among Bermuda grass golf courses is the coloring of dormant turf with a turf colorant instead of overseeding with ryegrass. This trend began with the coloring of Bermuda grass greens as they were going dormant. Instead of overseeding them with bentgrass or poa trivialis, a colorant was applied. This trend has been carried over from its use on greens with success. This coloring is now common on Bermuda grass fairways and tees.  It is an undeniable fact that ryegrass overseed competes with the Bermuda grass into which it has been overseeded. This creates a weakened Bermuda grass plant at transition time and the Bermuda grass will then spend the summer recovering from this competition. Another issue with overseeding is that it needs to happen in October when our weather and playing conditions are usually excellent. It is necessary to water heavily during overseed establishment which then creates unsatisfactory wet playing conditions. Cart traffic must then be restricted to cart paths during the establishment of the overseed.  This is never a popular decision.

This year at Forest Creek we decided to not overseed either golf course.  We have also decided  to color the fairways, tees, and  approaches on the South Golf course.  We are using Endurant turf colorant from Geoponics. This is a high quality product designed to be used on turf.  The golf course industry has responded to this trend  of coloring turf by developing better products for this practice..  These products are formulated to adhere to the grass plant while causing no injury to the plant. They are considered to be perfectly safe for both the plant and the golfer.  We applied the Endurant colorant to the front nine on Wednesday and the back nine on Thursday. The ladies golf group played the first round of golf on this newly colored turf on Thursday and the comments were very positive.  We anticipate that we will do at least two more applications throughout the dormant season to maintain a satisfactory color.

This process has been studied at the university level and the USGA has several articles which examine this process.
"Instant overseeding: coming to a fairway near you", by Patrick O'Brien, USGA Green Section Record Vol. 50 (14), July 6,2012
"Switching from traditional overseeding to liquid overseeding", by Todd Lowe, USGA Green Section Record Vol. 51 (22), November 1, 2013
