NOVEMBER-DECEMBER 2017 1 CONTENTS COVER The Australian Golf Club: The 18th hole at The Australian Golf Club, host of the 2017 Emirates Australian Open. Photo: Brett Robinson, AGCSA. For the third time in four years, course superintendent Phil Beal and his tournament crew at The Australian Golf Club in Sydney hosted the Emirates Australian Open in late November. As they did back-to-back for the 2014 and 2015 tournaments, the crew presented a course befitting of the country’s national Open - the 102nd - and again set a benchmark for course presentation. ATM editor Brett Robinson looks back at the tournament, Beal’s preparations and the long-awaited upcoming redevelopment of the club’s maintenance facility. 14 FEATURES Liberty National’s Aussie invasion It has been a whirlwind past 12 months for 2016 AGCSA Graduate of the Year Award winner Billy Koopmans. In addition to the award, Koopmans undertook an internship at Liberty National Golf Club in New Jersey, USA which culminated in the 2017 Presidents Cup. Koopmans looks back at the tournament along with Palm Meadows assistant superintendent Blaine Knox who was one of a number of Australian course volunteers. ATM also looks ahead to the 2019 Presidents Cup which returns to Royal Melbourne Golf Club. Bunkers are the bane of many a superintendent’s existence and what were once hazards now consume significant resources.

I was going to use this edition’s column to wax lyrical about the plethora of movements and retirements the industry has witnessed in recent months. I was going to kick off by lauding Tom Parker for signing off after 20 years as Sydney Cricket Ground curator, just the eighth in the ground’s 160-year history. I was going to say how refreshing it was to read his comments about the inflated expectations of those involved in the modern game and the resulting pressures he faced in such a high profile role which had, unfortunately, detracted a little from the love he had for the job. I was then going to commend Royal Sydney Golf Club on its decision to promote Adam Marchant to the role of course superintendent, just three weeks after the surprise announcement that Steve Marsden was departing in early 2018. While there was no doubt pressure to cast the net far and wide to find a replacement, it was fantastic to see the club promote from within and back a hard-working lad from Mudgee who has developed into one of the industry’s finest. And finally, I was going to ponder some of the questions I’d fire at Gary Dempsey after he recently revealed his impending retirement as NSW Golf Club superintendent next July. Finishing what will be one year shy of 30 years at the La Perouse coalface, I’m sure the ‘exit interview’ will elicit some classic tales and industry home truths. All this, however, was put to the side when news filtered through in late November that the industry had lost one of its true standard bearers. This time, however, it wasn’t another superintendent or curator, rather a publication that had become an important part of the fabric of the Australian turf industry for the past three decades. In the November-December 2017 edition of TurfCraft International, long-serving editor Alastair Dowie revealed that it - the magazine’s 177th - would be the very last. Owners Fairfax Media were closing the publication down. It was certainly a sudden and very sad way to end such a distinguished tenure and as a fellow journalist and editor I can only imagine how difficult it would have been for Alastair to pen his final editorial. Being an editor of a small, niche industry publication like ATM or TurfCraft is unique. Just as a superintendent or turf manager develops an affinity for their patch of turf while in charge, as an editor it is also hard not to become personally invested. For the past 20 years TurfCraft International was Alastair’s and he successfully built on the solid foundations laid by outspoken predecessor and founder Ted Drinkwater. Under Alastair’s editorship, the magazine continued to steadfastly deliver on its original remit of being “a national forum for the interchange of knowledge between all elements of the recreational turf industry”. One of the things the Australian turf industry prides itself on is its fraternal nature and the manner in which it works together for its betterment. While TurfCraft may have been a rival (trust me, on more than a few occasions over the years I would let rip with a few expletives upon discovering Alastair had scooped ATM), at the end of the day both publications always had the same principal focus and motivation - to acknowledge, promote and highlight the efforts of the industry and its skilled practitioners. Through the pages of TurfCraft International, Alastair was a passionate advocate for the industry and provided a vital medium through which members could tell their story. Its breadth of coverage of all sectors of the turf industry can only be admired and the abruptness of its departure leaves a significant hole. The passion and pride it always carried for the industry could never be questioned and to Alastair we indeed owe a great debt of gratitude. His presence, and that of the TurfCraft International masthead, will be sorely missed.

Over a busy first few weeks I have had the opportunity to meet a number of members and supporting partners, during which time I’ve seen and heard some great success stories and also learned what a challenging time the past few months have been. summer with the dual issues of low dam levels and next to no existing soil moisture. It is worth noting that among all the discussions I have had with superintendents, such challenges were being meet with an approach of simply getting down to business and working through it, which is a testament to the people we have in this industry. PROMOTING THE GAME, EDUCATION Over the last few weeks I have also spent time with the PGA of Australia, Golf Australia and Golf Managers Association examining the approach and challenges for golf in Australia over the next few years. We discussed the importance of all areas working together toward a common objective of promoting the game of golf and those who work in the industry. On the topic of those employed in the industry, planning and preparations are well underway for the inaugural Australasian Turfgrass Conference and Trade Exhibition in June 2018. In what will be an industry first, the AGCSA has partnered with the New Zealand Golf Course Superintendents Association (NZGCSA) to expand the reach of this industry-leading event further throughout the Pacific region. To be held in Wellington, New Zealand from 24-29 June 2018, the conference promises to be an event not to be missed. I know many of you have expressed great interest in the event being staged with the NZGCSA, as it allows for a wider range of presenters, topics and significantly increases the event’s exposure to a worldwide audience. As a brief overview, a range of international and local speakers has been lined up, coupled with guest presenters and extensive educational programmes, not to mention a series of expert This is also my first opportunity to publicly thank the AGCSA team, members and those in the industry for the warm welcome I have received, and to the Board for their support in appointing me to be a part of this industry-leading association. The coming weeks and months will be spent meeting as many members, partners and industry supporters as possible, continuing to develop a more in-depth understanding of the industry and commencing working through planning for 2018. The AGCSA has a long and proud tradition of leading the development of initiatives, research and information to support its members and these remain areas of focus for myself and the team over the coming year. As mentioned, it has been a challenging few months weather-wise, with variable weather conditions in the early weeks of Spring creating a few headaches for superintendents and their teams. Queensland experienced its lowest monthly rainfall in over 15 years, while in New South Wales and the Murray Darling region as a whole, September rainfall was the lowest on record. Quite the opposite was experienced for others throughout WA, some coastal regions of SA and Victoria and parts of Tasmania, who saw a wetter than average September and October. Following on from low rainfall and some of the warmest winter temperatures on record across parts of Australia, there is now the prospect of facing a hot OAGCSA AUSTRALASIAN TURFGRASS CONFERENCE & TRADE EXHIBITION WELLINGTON 2018 Turf Drain Australia The leaders in sports field drainage & sports field construction using the latest machinery & technology.

Make sure to check out the dedicated conference website - www.atc2018.com - for further details and register to take advantage of AGCSA member Early Bird specials. The AGCSA has also recently spent considerable time in discussions with a range of industry and education bodies to ensure alignment at a national and state level regarding the level of education provided across turf related courses. The work and commitment coming out of these sessions has been great and our aim is to continue this to safeguard the quality of education provided to the turf professionals of tomorrow. Continuing on the education theme, some of the preliminary discussions undertaken with various industry bodies have been with a focus on putting programmes in place to ensure the role of superintendents (and their teams) is recognised for the value they bring to the game. Additionally, that appropriate development and education pathways are made available to superintendents, assistants, 3IC’s, groundstaff, technicians, turf managers and all other associated roles in order to provide a platform to enable continuous learning and development. This is a priority of the AGCSA heading into next year and we will continue to work with members, partners and the state associations to deliver this programme of work. More information will be available early 2018 as these discussions and our approach evolve. The final few weeks of this year will see the AGCSA focused on finalising events and activity plans for 2018. Following tremendously successful events in regional Victoria and NSW, we will be expanding our free ‘walk ‘n’ talk’ sessions to more states and courses across regional and metro areas, as well as rolling out health and wellbeing and business networking sessions in conjunction with supporting partners. Also in the pipeline for 2018 is a range of increased member services, including environmental initiatives, governance and compliance, and education and professional development seminars. We will continue to ensure the delivery of these sessions is planned to reach as many members as possible and will keep you updated through ATM, The Cut and the AGCSA website. In addition to continuing (and expanding) our agronomy and research programmes, industry representation and updates to Best Practice initiatives throughout 2018, the AGCSA will be actively working with members for ways we can assist you further. If there is anything you would like to discuss or feel the AGCSA should be providing, please don’t hesitate to get in touch with myself or the AGCSA team. It certainly has been an interesting first few weeks.

As they did back-to-back for the 2014 and 2015 tournaments, the crew again set a benchmark for course presentation. hil Beal is the first person to admit that he has a tendency to get a little tense when an event like the Emirates Australian Open lands in his back yard. No surprise in that really. The collective eyes of the golfing public, the players, the media, worldwide television audiences and, of course, the members are all on you. Your skills as a course superintendent are under the microscope for four physically and mentally exhausting days. Come the Saturday before the tournament’s 102nd instalment in late November - the 20th occasion The Australian was hosting it - Beal found the tension levels rising for a very different reason. It had nothing to do with the weight of expectation or the turf surfaces. All that was well in hand. Rather, it was the gentleman who’d just come into his office and was now sitting on the other side of the desk who was giving Beal cause to stress. Josh Cuch (those who know him will probably be laughing about now) is, well, a character. The Australian Golf Club’s larger than life turf equipment technician is an ideas man and in the weeks preceding had been in his boss’s ear about doing something different when welcoming this year’s crop of Open volunteers - all 30 of them - at their first gathering on the Saturday. Cuch had it all choreographed - Beal, along with assistant superintendent Dave Smith and 3IC Chris McCulloch, would make a grand entrance to music - and with the volunteers having just arrived at the maintenance facility it was show time. Beal, ever the demure Englishman, was having none of it. A few minor things hadn’t gone to plan that day and when Cuch purposefully strode into the office and asked “Right! What music do you want?”, Beal turned to him and said bluntly, “I’m not doing it.” Cuch ignored him and continued talking animatedly about it to Smith and McCulloch before Beal interrupted and reiterated, ‘Josh, we’re NOT doing it!” — Few could fault the conditions presented at The Australian Golf Club for the 2017 Emirates Australian Open. Headline act Jason Day described the efforts of superintendent Phil Beal and his crew as “phenomenal” Phil Beal (left) and tournament director Trevor Herden deep in discussions ahead of the final round Cuch isn’t one to give in easy, however, and had one final trick up his sleeve. Upon looking up, Beal caught the eye of a now somewhat emotional 6’5” turf tech - Beal swears there were a few tears welling up - and knew he was done. “How the hell can ANYONE live with you Josh! Fine, let’s do it!” Score! A few moments later a rather sheepish looking Beal, Smith and McCulloch were walking the few metres from their shared office to where the volunteers had assembled inside the maintenance facility. The unmistakable opening bars from Survivor’s ‘Eye of the Tiger’, made famous in the film Rocky III, were blaring out of the stereo and there grinning, laying down a shroud of CO2 gas from a fire extinguisher, was the mastermind Cuch himself! Tournament preparations could now commence. “It was brilliant,” reflects Beal seven days later from his office as the third round of the 2017 Emirates Australian Open is in full swing. “I was a bit stressed that day - the most I had been for the whole week - and I just didn’t want a bar of. But it was the best thing we could have done. Everyone just fell about and loved it. It was a great way to break the ice and it set the tone for what was a fantastic week. ON POINT The 2017 Emirates Australian Open was The Australian’s third in four years and Beal will attest to the notion that the more you do something the better you get at it. While the playing surfaces presented in 2014 and 2015 were top notch, this year it was about learning from those past tournaments and getting everything on point before the circus rolled into town. Whether it was better coordinating the volunteers, not pushing the crew as hard or just being more in control of where his turf surfaces were at, there was definitely a more relaxed and seamless feel to preparations this time around. OPEN <4 Open volunteer Trevor Ridge shaves the 7th fairway at 8mm The Australian 3IC Chris McCulloch monitors moisture levels on the 2nd green during final round preparations “They were sensational,” says Beal. “I think we took the presentation of the fairways and greens surrounds up another level this tournament. They were a lot firmer than in the past and we had some great feedback from the players and tournament officials. It is something we have worked on since the course redevelopment and hosting the 2014 and 2015 tournaments. Every year we’ve been going very hard on them - not the most popular decision with the members - but you could see out there this year it has really paid off. “Last year we bought a Koro field topmaker and put some scarifying units on it and went really hard in December which I feel really helped achieve the density and firmness we were able to get during the tournament. Then in September, as part of our normal renovations, we went back out and put the verticutting heads over them, scalped them down 6-8mm and topdressed heavily. They took a long time to come back but I think we nailed it with what was presented. “We didn’t apply any Primo to the fairways this time. We had used Primo in 2015 and they were sensational and I really thought I needed to get some applications out again this time around. But it was too cool and the grass just seemed to be under control anyway - it just did its own thing. We foliar fed when necessary and by two weeks out we knew we had them right so we just left them as they were. We cut them at 8mm for the first time and the tightness and firmness we achieved was pretty cool. “The only thing I didn’t nail, again, were the tees. Every tournament I have struggled with the tees and it’s fair to say they’re driving me nuts. I don’t know what’s going on. It’s a different grass - Grand Prix couch - and I think maybe I need to do a bit more homework on it, maybe see what some of the guys down in Victoria do. We do get a fair bit of ERI-type disease through them and it’s not for the lack of preventatives. There’s something that I’m obviously missing and need to adjust.” CONTINUED ON PAGE 11 As Beal describes it, the way the course presented this November was “different” to versions 2014 and 2015. The roughs for a start were vastly different, almost non-existent. Having learnt from the pain of previous tournaments, where promoting the roughs beforehand made the course almost unplayable for members post-tournament, Beal deliberately didn’t try to push any growth. Combined with what he suspects was a bit of couch mite damage and dry conditions, the roughs presented somewhat brown for the tournament. Beal admits he actually preferred the look and reckons it gave the course “a gnarly” look on its flanks. Most pleasing for Beal, however, was the presentation of the Santa Ana couchgrass fairways. Cut at 8mm, down from 10mm at the last Open, the aggressive attention they received as far back as last December made them the talk of the tournament. So tight and pure were they, that it even prompted Golf Australia to post on Twitter - “It’s very rare that fairways are in such good condition that they can be cut to 8mm. But that’s what we have right now #AusOpenGolf #Mint.” Tournament headline act Jason Day, was also in high praise of the surfaces. After Wednesday’s Pro-Am he commented: “The course is in great shape; the superintendent and his staff have done a phenomenal job getting the course ready.” The par three 15th gets one last trim before the final round 8 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 A NUTURF SPECIALISTS PROVIDING SOLUTIONS STAMINA Make your water work for you with a* desighed ‘ 'IT specifically for your conditions • The Stamina Range is designed and made locally for local conditions • The staple wetting agent solution for countless turf managers • Comprehensive range with a solution for every scenario • Low burn formulations for exceptional plant safety • Performance and plant safety backed by extensive field trials for peace of mind • Premium quality BASF surfactants for top quality formulations.

Despite a sodden Pro-Am on the Wednesday, conditions for all four tournament rounds were perfect, with the wind raring its head a little to provide some defence of the course. The greens were a little soft on the Thursday thanks to that rain and the scores reflected that, but as the course dried out there was ultimately just a three shot difference between the leading score after round one and Cameron Davis’ championship­ winning total of 11-under. “I was very happy with the greens,” states Beal. “Every year beforehand I think they’ll beat the place up and maybe they do for the first round, but then the course comes into its own. We definitely jagged the weather this year and Chris (McCulloch) and Dean (Hardman) did a great job hand watering to keep moisture levels where we wanted them. “They were a little soft for the opening round, but after that they were great and rolled to a speed that (tournament director) Trevor Herden needed (mid to high 11s) and they didn’t shift all weekend. One thing I like to do is go out after each round and look at the greens and have a bit of a putt on them. It was so pleasing to see there was very little difference from the morning, with the putts still tracking beautifully and rolling true. JT TURF IS NOW THE NATIONAL DISTRIBUTOR OF LASTEC ARTICULATORS Now the assistant at Killara, Dean Hardman returned to his former club to assist with handwatering greens during the Open “We renovated the greens in the first week of September and went quite heavy with the sand, dusting every 10 days until about 2.5 weeks out. They took a while to come back. It was fairly dry and windy during that period and I think I missed a trick on the higher areas. We didn’t have the moisture levels quite right and you could see the core marks in a few of those areas during the tournament. But I deliberately didn’t push them - you’re just wasting your time. If you fertilise them they just thatch up and you get to a place where you don’t want to be. “We double cut every day at 2.8mm and didn’t have the rollers on them at all. I’m not a great advocate of using rollers on these greens. I just feel that it irons them out and the grass just stays there - it looks lazy. While you get greater speeds, to me you lose the consistency and I don’t like that.” ^^ .k The Turf Strength Specialist*Aicl TORO NOVEMBER-DECEMBER 2017 25 BUNKERS <4 The USGA recommends an average sand depth of 4-6 inches at the base of a bunker and 2-3 inches on bunker faces Many golf course officials do not realise the resources required to maintain high-quality bunkers, but it is an important topic, especially as some facilities are forced to conserve resources bunkers that require more hand labour due to intricate designs, can significantly increase maintenance costs. However, labour can be reduced by not raking every bunker on a daily basis, as long as golfers are accepting of occasional footprints or inconsistent lies. PLAYABILITY Inconsistent playing conditions can occur even in properly constructed and maintained bunkers. Bunker playability often is contingent on sand firmness which is most affected by moisture. Therefore, factors that affect sand moisture strongly affect bunker playability. Some factors affecting bunker sand moisture can be managed with daily maintenance practices, while other factors cannot. It is important to understand the impact of each factor on playability to help determine the degree of bunker consistency that is achievable and sustainable at your facility. Some factors affecting bunker sand moisture include: • Sand depth: Bunkers with more sand are generally drier (softer), while shallower bunkers are generally wetter (firmer). It may be possible to change bunker firmness by simply adding or removing an inch or two of sand. • Weather: Rainy periods keep sand moist and firm, while droughty weather can result in dry, soft sand (depending on irrigation). Irrigation coverage: Bunkers that receive additional water from sprinkler overlap remain wetter and firmer. • • Shade: Shaded bunkers dry out slower and remain firmer than bunkers in full sun. • Sun angle: Bunkers on south-facing slopes receive less direct sun, dry out slower and are firmer than north-facing bunkers. • Topography: Elevation affects bunker moisture and firmness. Low-lying bunkers that are near the water table may remain saturated and firm, despite having a functional drainage system. The term ‘consistency’ is often used when discussing bunker playability, but bunker consistency might be an impossible standard. Bunkers can be raked the same way and maintained at the same depth, but it is impossible to account for all of the above factors to maintain consistent playability in every bunker on a daily basis. It should be remembered that the game of golf is enjoyed outdoors and it is rewarding to make good shots from bunkers that are affected differently by outside elements. Golfers should understand howto recover shots from firm and soft playing conditions and perhaps take a few lessons from their local golf professional. Golf is a self-governed sport that encourages each player to use etiquette on the course and rake bunkers after each use. Another bunker etiquette issue occurs when golfers damage steep grass faces by attempting to traverse them instead of exiting the low side of a bunker. Signs can be posted to educate golfers on this issue and encourage them to protect bunker faces. Lastly, the placement of bunker rakes following use is another common topic with golfers. Bunker rakes can be placed either inside or outside of bunkers and it is up to each facility to develop their own policy. However, placing rakes outside of bunkers, in areas where they are least likely to affect play is generally recommended. CONCLUSION Bunkers come in all shapes and sizes. Some bunkers are neglected and some receive intensive maintenance. High standards for bunker quality and consistency usually require increased inputs. The amount of labour and resources required to achieve desired bunker playability and appearance depends on factors such as bunker construction method, design and the physical characteristics of bunker sand. Golf course superintendents strive to provide consistent playing conditions on all playing surfaces. However, maintaining consistent bunker playability on any given golf course can often be an impossible, or financially unsustainable, task. At the end of the day, bunkers are considered hazards and are areas that should be avoided. Have golfers ever complained that the water was too wet in a lake or pond...?

Cypress Lakes Resort in the NSW Hunter Valley started construction in 1990. Prior to being transformed into a golf course, the land was used for cattle and sheep farming. The original farm owners decided to sell as the site had very little topsoil, no water and was on an iron stone rock shelf. Two hectares of the site was used as a rock quarry where the current clubhouse and conference centres reside today. Steve Smyers, a Florida-based golf course architect, was engaged to design and construct the first resort course in the Hunter Valley wine region. The course was built over two stages and was opened in 1992. A par 72, 6467m championship course, each tee and green offer stunning panoramic views of the Hunter Valley’s famous vineyards and the surrounding Brokenback mountain range. The course was planted with Wintergreen couch on fairways and green surrounds, Greenlees Park couch tees and greens seeded with Penncross bentgrass. The course and clubhouse surrounds are currently managed by 13 staff with the original layout comprising 60 bunkers with 1.2 hectares of sand, 17ha of fairways and closely mown turf and 1ha of greens. The golf course and clubhouse surrounds are irrigated with treated effluent water from an onsite treatment plant, with additional water supplied via private irrigation distribution (PID) from Hunter River and an onsite storm water runoff storage. In peak irrigation season, the resort uses 1.3 million litres per night. In October 2013, Oaks Hotels and Resorts purchased the management rights of the resort villas, purchased outright the reception building and conference facilities and lease of the golf course for two years until they purchased it in 2015. Since the change of ownership, Oaks Hotels have invested $5 million into the golf course and resort. As part of Oaks Hotels’ acquisition of the resort, Golf Business Advisory Services engaged Turfwise Consulting to undertake a review of the course operations at Cypress Lakes Golf and Country Club, with the objectives of; • Assessing the turf and asset condition, as well • as human resources; Identifying and reporting on the areas of course operations that required investment to enhance course quality, efficiency of maintenance and management, meet key market demands, maximise participation and optimise return on investment; and • Make recommendations for implementation of necessary investment or change. The findings clearly indicated a need to take immediate action on upgrading the irrigation system ($1.6 million staged over three years), purchase of essential equipment ($1 million) and undertake a review of bunker design in consultation with a course architect to determine strategies to reduce maintenance demands ($1 million). It was decided to upgrade the turf equipment and irrigation control system immediately and review the bunker design, economic, social and environmental dimensions over the next two years to develop a bunker improvement programme. The challenge 28 AUSTRALIAN TURFGRASS MANAGEMENT 1' surrounds and tees and Toro infinity DT54s on fairways. With the bunker project approval imminent, we expected a short installation window for Stage 1 of only 10-12 weeks. Hydro Technics Irrigation were successful in winning the tender and started work on 3 November 2016. As they say ‘when it rains it pours’ and just a week after Stage 1 of the irrigation project got underway we were given approval to start the bunkers, nearly 18 months after the storm. We now had two major projects on the go! The irrigation installation went very smoothly and fortunately we didn’t lose a day for wet weather with the project completed on 25 January 2017, a week before we were to start on the bunkers. BETTER BUNKERS Our insurer undertook a review of the original bunkers, with the objectives of minimising surface water runoff into the bunkers, raised turf rolled lips and installing a liner to the clay sub-base to reduce future contamination. In early 2017, Flemming Golf was awarded the contract to restore three bridges, all bunkers and the 13th tee as part of the insurance brief. Like every project, it started with a budget and from there we realised we needed to rationalise not only the number of bunkers, but just as importantly the area of bunkering. There was in excess of 1.2ha and with that came the potential of a ballooning budget just to keep them playable. As we set about redesigning the bunkers we wanted to make the majority of them contribute Opposite page and below: In April 2015, Cypress Lakes Resort was hit hard by a super storm cell that uprooted 300-plus trees and washed out all bunkers on the course Bottom: The storm led to major sand contamination issues which compromised the drainage of almost all the course’s bunkers ► NOVEMBER-DECEMBER 2017 29 was to deliver a balance between playability, sustainability, safety and course aesthetic, while at the same time maintaining Cypress Lakes’ high standard for bunker quality. Raking, edging, debris removal, weeding, mowing, trimming and wash-out repairs were high maintenance inputs required of the existing bunkers. SMASHED In April 2015 the Hunter Valley was hit by a severe super storm, a one-in-100-year event which resulted in a state of emergency being put in place across the Pokolbin area. Cypress Lakes Resort took the full brunt of the storm. The course copped 260mm of rain in 24 hours and recorded wind speeds in excess of 110kph which brought down over 300 mature gum trees. Loss of power to the resort for nine days combined with the storm damage meant the resort had to be evacuated. The storm caused major damage to the course - three bridges were washed out, 700 metres of bitumen pathways were destroyed and the sand on all 60 bunkers washed from the faces which contaminated the subsurface drainage. The bunker drainage silted over and required repeated pumping out following rain events. Any rain event over 5mm would flood the bunkers and over a 12-month period we pumped over 12 million litres of stormwater from the bunkers. We were becoming concerned that the cost of maintaining our bunkers was approaching the cost of maintaining our greens! An insurance claim was made soon after the clean-up had finished in May 2015, but approval wasn’t given until late 2016. While we were waiting on the insurance claim to come through, it was decided to make a start on Stage 1 of the irrigation system upgrade. Total Irrigation Designers (Matthew Wilson) was selected to design the irrigation master plan which would be installed over a three-year period. Toro Infinity 835 heads were chosen for greens, greens BUNKERS All contaminated bunker sand was removed and stockpiled on each hole and then reused as a final trim sand for the bunker surrounds strategically to a round of golf. There will always be a few bunkers that will have a greater aesthetic appeal than strategic, but a happy balance was what was sought to re-establish the course as a high- end resort facility. So, after a thorough review we decided to remove some, reduce the size of others, shift others closer to the line of play and add a few extra where we felt they would positively contribute to the golfing amenity. SHIFTING SANDS Construction started on 30 January 2017 with a proposed completion of 20 weeks subject to agreed delay days. During the project we lost 16 days due to wet weather and a further two days due to excessive heat above 46 degrees. The process started by reviewing the number and location of the bunkers. Generally, the project team - consisting of James Wilcher (architect), Kirk Flemming, Vince Flemming and Craig Brown (construction shapes) and myself (superintendent) - collaborated on a style of bunkering that we felt would suit the site, but at the same time have its own distinctive character to set it apart from other courses in the Hunter Valley. We wanted Cypress Lakes to look grand and encourage golfers back to the resort; we weren’t going to do that if the bunkering didn’t have some sort of ‘wow’ factor! We settled on a style that made the most of the contrast that bunkers offer the golfing landscape, yet fitted into the topography across the whole site, flat or challenging. Of course, retrofitting bunkers into pre-existing greens was a challenge. We felt that if we could do this, control surface water and reduce The project team wanted to ensure Cypress Lakes’ bunkers were grand and had a ‘wow factor to them, but at the same time designed with reducing maintenance issues in mind 30 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 the drainage burden on the bunkering generally, we could achieve something that was distinctive but also take some pressure off maintenance costs. The construction process went as follows; • Concept master plan and on-site modification; • Transfer design from the GPS onto the ground; • Remove existing contaminated bunker sand and stockpile; • Bulk shape new design; • Replace stockpiled sand around bunker edge; • Detail machine shaping and drainage; • Detail hand work ready for turf and liner installation; • Drainage and sand installation; • Irrigation head modification; and • Turf. Golf by Design (James Wilcher) provided the construction team with a detailed concept bunker plan. This plan was used to tender the project and to provide a starting point for each of the holes. The concept plan was loaded into the GPS system and transferred onto the ground in draft format. All of the contaminated bunker sand was removed and stockpiled on each hole to be used. During the stockpiling process we noticed that the contaminated sand’s characteristics would form a very good final trim sand. The sand dried firm but once water was applied it become workable without collapsing, saving us thousands of dollars not having to import topsoil. Bulk shaping was carried out using a CAT 314D excavator with a power tilt bucket. We selected this machine over the dozer to keep as close as possible to the confined work zones. These works zones were extremely important as we had to ensure they didn’t extend too far as all pricing was based on these areas. As bulk shaping finished, the stockpiled sand was roughly placed around the finished GPS line ready for the detailed machine shaping. Detailed machine and hand shaping involved spreading and shaping the trim sand to the agreed architectural design, spading the final edge and then shelling out the clay subbase to a 60-degree slope and cutting in subsurface drainage ready for liner installation. What type of liner to use? That was the question we kept asking ourselves from the start of the project and we eventually choose a fabric liner from Polyfabrics Australia - Terra Stop non-woven Grade TASIF. The liner decision became financial. We could install the fabric liner for $15 per square metre which was in our budget, whereas other products we looked at would have increased the overall construction price by $540,000. The liner was wrapped 300mm over both front and rear lips and encased all drainage trenches. Oiled pins were hammered in every 300mm around the bunker edges and joins and every 350mm-450mm on the bunker faces and subbase. A 200mm line was dotted below the edge to indicate the finished turf line. Bunker sand selection was limited. We chose to have two white bunker sands independently tested through AGCSATech. One of the sands was locally sourced, but consistent quality couldn’t be guaranteed over the 20-week project. We selected a crushed sandstone from Maroota, west of Sydney. While, the sand didn’t meet all the requirements of the bunker sand specification, experience of bunker sand performance would indicate that those with ball penetration results higher than 1.8kg/cm2 are generally acceptable, especially if the sand within the bunker isn’t allowed to become excessively dry. From the findings we decided to install additional irrigation heads around bunkers. Like most projects we had a few challenges early on, most of which we couldn’t plan for. During the first four weeks we received 204mm of rain which delayed the project 11 days. Fortunately, April was dry and we were able to get back on track. Over the 24-week project thorough communication from the construction team made the process seamless. James Wilcher was on site each week and any changes were agreed to a week ahead. Communication to Oaks management occurred via monthly reports, with these then forwarded to the insurer. Members and guests were also kept up to date with designated noticeboards displaying plans for each hole. Communication was perhaps the biggest lesson that I took from this project - providing as much written and visual information as possible to members and guests. CYPRESS SUCCESS Planning of the project took 18 months and proved to be a key factor in the overall success of the project. Careful shaping and improved bunker design and drainage has allowed us to now collect runoff and subsurface bunker drainage water in on site storage lakes. As we assess the success of the bunker project, we have experienced a significant labour reduction, our energy and water management has improved and we are now collecting over 7.5 million litres of stormwater from our bunkers. This stormwater is directed from our bunkers to our dams for reuse on the course for bunker irrigation. Based on four environmental indicators - greenhouse gas emissions, primary energy use, water use and land management, our bunkers now have significantly lower environmental intensities. Our labour inputs have decreased by 10 per cent, safety to staff and golfers has considerably improved, and, from a corporate governance perspective, our new bunkers have added valve to the business. One final piece of advice I would give to other superintendents looking to undertake a similar project, is purchasing a drone. Our drone was used to document the various stages of works and it also helped us to identify irrigation and drainage lines prior to construction starting. The drone was used daily for before and after shots which formed part of our monthly reports to the insurer. Although the construction works were GPS’d to form an ‘as built,’ we took additional drone shots for quick references. The drone is still being used today to identify irrigation issues, checking dam levels, inspecting brush fire hazards, promotional photos and roof inspections. The purchase of a drone proved invaluable to Molloy who was able to utilise it to take aerial photos before, during and after construction.

Golf course irrigation systems can quickly deteriorate from lack of maintenance. Irrigation system maintenance is primarily reactive at most golf courses (i.e.: when a component of the irrigation system breaks or is not properly working, an irrigation technician or other senior crew member is dispatched to make repairs). Preventive maintenance can reduce the amount of reactive maintenance and improve playing conditions. Developing a preventive maintenance programme is the best way to extend the life of an irrigation system, maintain performance and minimise the severity and frequency of problems. Preventative maintenance programmes must be customised to meet the unique needs of an irrigation system and based on a thorough check of the system and its components. As with any preventive maintenance regime, some tasks will need to be accomplished on a daily, weekly or monthly basis, while others may require attention quarterly, semi-annually or annually. Of course, while preventative maintenance reduces irrigation system problems, it does not eliminate some tasks that must be completed on an as-needed basis. So, what does a preventive maintenance programme look like for the irrigation system at your golf course? It depends on the type of irrigation equipment and its age, but a typical programme includes the observation, adjustment and maintenance at regular intervals of sprinklers, valves, controllers, pump systems and other better than cure maintenance can reduce Irrigation systems are an integral part of golf course maintenance, just like maintenance staff, mowing equipment and maintenance facilities. Without a functional irrigation system it is virtually impossible to maintain golf course turf in a playable condition. Irrigation system preventive labour and materials costs and may also help save water and energy while improving playing conditions. However, while mowers and other equipment are regularly seen working on a golf course, irrigation systems are a mystery to many golfers because they are buried underground and most frequently operate at night. Therefore, it can be difficult for golfers to understand that irrigation systems wear out and are very expensive to replace. A new irrigation system can cost into the millions depending on location and complexity. 32 AUSTRALIAN TURFGRASS MANAGEMENT components. The following sections of this article can be used to create a customised preventive maintenance checklist for any irrigation system. DAILY MAINTENANCE On a daily basis, the maintenance staff should perform the tasks that are a normal part of routine irrigation system operation and management. Examples include the following tasks: • Observe golf course turf conditions for wet and dry spots. • Review the irrigation programme from the previous night to confirm that the irrigation system operated on the programmed schedule. • Check the pump system monitor for any inconsistencies or abnormalities. This may be done remotely depending on your pump system equipment. • Review and record water use from the previous night’s irrigation cycle. 9 Document evapotranspiration with a weather station or online source. • Measure any precipitation using a simple rain gauge. • Log any pipe breaks and component failures. • For two-wire systems, check the operating log in the central control software diagnostics to verify normal communication between the central control software and each sprinkler or valve. Investigate stations that report possible issues. Sprinkler nozzles should be frequently checked for clogs and wear. Also, ensure that the proper nozzles are installed in each sprinkler • Prepare and prioritise irrigation repair orders and discuss them with the appropriate personnel. Assign additional staff to assist with repairs if necessary. • Determine the water requirements for the next irrigation cycle and adjust the programme accordingly. WEEKLY MAINTENANCE Daily observation and maintenance should occur as part of normal irrigation system operation. On a weekly basis, time should be allocated to inspect the irrigation equipment itself and to make sure it is functioning correctly. Because the irrigation Where FLEXIBILITY meets PERFORMANCE.

Check and trim turf around sprinklers every month system most frequently operates at night, issues are not always obvious without inspection. Therefore, preventative maintenance on a weekly basis should include: • Check sprinkler operation and answer the following questions: • Do any sprinklers appear to be turning faster or slower than usual? If so, time them to be sure. • Does each sprinkler pop up, turn and retract? • Are part-circle sprinklers turning in the correct arc? Is there any leakage? • • Are any nozzles clogged? • Update the central controller database with any changes. • Check the condition of valve boxes and covers. • Review the status of irrigation repair orders. Order necessary parts to complete repairs if they are not in stock. • For two-wire systems, use software diagnostics to check the performance of each wire path for abnormalities such as excessive or unusual current draw and low-voltage reports. • Visually inspect the condition of the pump station. MONTHLY MAINTENANCE Approximately once a month, course staff should: • Check that sprinklers are not blocked by surrounding turf and trim around sprinklers as necessary. Inspect valve assemblies for leaks or damage. • • Examine and clean filtration devices. Check for wear on filter screens. • Review, and consider adjusting, temporary changes made to irrigation station run times during the previous month. • For two-wire systems, use software diagnostics to run a voltage check of every sprinkler or valve in the field. Compare voltage readings to results from the previous month to verify that there is no unexpected drop in voltage. Inventory and restock irrigation repair parts. • QUARTERLY MAINTENANCE Dust, dirt and debris can damage irrigation controllers and pump systems. Quarterly cleaning can significantly extend the life of system components, especially electrical items such as central computer Checking the satellite controllers and central computer for backup programmes and accurate run times should be done at least once every month 34 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 controls and field satellites. Quarterly maintenance should include: • Clean satellite controllers and replace insect repellent. • Clean the pump system, pump house and irrigation parts room. • Remove dust from the central computer using a compressed-air duster. • Check if software updates are available for the central control system and install them as necessary. • Clean out rain gauges. • Listen to the pump system as it starts up and shuts down during an irrigation cycle to ensure that it is operating correctly. Check to ensure that pumps turn on and off smoothly, watch for excessive cycling and listen to how the drive ramps up and down. SEMI-ANNUAL MAINTENANCE • Exercise all quick couplers on the course, especially those that are rarely used. • At minimum, record pressure readings at high and low points of the irrigation system using quick couplers and a pressure gauge. Compare readings to previous results and note any changes in pressure to identify potential problems. • Pump system service should occur semi­ annually at minimum in climates with a 12-month irrigation season. ANNUAL MAINTENANCE • Exercise all isolation valves and drain valves to prevent them from sticking open or closed. • Pump system service should occur annually in climates with a six to eight month irrigation season. • Pressure-wash pump system filter or “Y” strainer screens. Check intake screens for clogging and debris. • Test and certify the function of any backflow prevention devices. Hire a certified technician that works in accordance with state and local testing requirements. • Test and service pressure-regulating devices. • Test, clean and service air-release valves by flushing “Y” strainers and exercising ball valves. • Level and set sprinklers and valve boxes to grade. • Check antennas and their connections. • Back up map and programme databases on the central control system to an external device. • Renew central computer service plan and update the computer according to service schedules. • Check field controllers to ensure that backup programmes are still installed and relevant. • Calibrate flow meters on the pump system and water sources.

Pumps are the heart of an irrigation system. Semi-annual maintenance of electrical and mechanical components by a trained technician ensures efficient operation DIAGNOSTICS AND REPAIRS With new technology, some of these tasks can be automated or are incorporated into the features of irrigation equipment. Today’s central control systems have the ability to diagnose or troubleshoot 36 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 many aspects of a golf course irrigation system. They are often able to pinpoint where problems are occurring and can provide diagnostic data such as voltages and amp draws at every sprinkler. These troubleshooting features, currently available with newer irrigation systems, will only expand and improve in the future. In order to efficiently service an irrigation system, it is important to maintain a small, on-site inventory of irrigation parts. It is difficult to perform maintenance when parts must be ordered every time something goes wrong. Parts inventories should be diverse. However, every golf course should have at minimum a selection of fittings, a small amount of pipe, and repair couplings for every size of pipe used in the irrigation system. Additionally, sprinkler bodies and internals, sprinkler control wire, wire connectors, gate valves and a variety of nozzles should be readily available. Other items that are good to have on hand include a spare faceplate and several spare circuit boards for field controllers; an electrical multimeter for testing voltage, amperage and resistance; a metal detector; and a wire locator. Two-wire systems will require more specialised diagnostic equipment such as a clamp meter and wire radar device. Depending on the age and amount of time required to maintain an existing irrigation system, employing an irrigation technician may be advantageous. Irrigation technicians focus on performing both reactive and preventive maintenance, checking pump system operation and keeping the irrigation computer database accurate. A properly trained irrigation technician will keep an irrigation system functioning as intended while reducing additional costs. A side benefit of proper irrigation system maintenance is the potential for reduced water use. When an irrigation system is in good condition, it is more efficient and saves both water and energy. CONCLUSION Although a preventive maintenance programme will not make an irrigation system last forever, it will reduce the labour and materials costs associated with keeping the system operational. It may also help save water and energy while improving playing conditions. A well-maintained irrigation system can even help reduce the stress level of maintenance staff by providing a dependable system they can rely on during hot, dry days when it is most needed.

Ten years on, he looks back at how the scheme has evolved, some of the lessons learned and asks whether it has all been worth it. Above: Glenelg was one of three Adelaide golf clubs to invest in an aquifer storage and recovery scheme in the 2000s. The scheme has settled in well, with performance becoming more reliable and predictable It’s hard to believe 10 years have passed since the last time I wrote about the aquifer storage and recovery (ASR) Scheme at Glenelg Golf Club (ATM Volume 9.5 - Sept-Oct 2007, ‘ASR scheme gives Glenelg the green light’, p12-16). Pardon the pun, but a lot of water has literally gone under the bridge since then, so the chance to put together some thoughts on the scheme’s operation is very timely. The primary objective of the scheme for Glenelg Golf Club (GGC) was to secure a high quality water source for the course for the foreseeable future. There was also genuine interest in the environmental benefits of such a scheme (i.e.: reducing stormwater outfall to the ocean and replenishing the depleting Adelaide Plains aquifer), with the club being mindful of positioning itself as a responsible corporate citizen in an increasing environment of public scrutiny over water use for turf irrigation. Adelaide has a proud history of ASR scheme operation, with the work of the City of Salisbury deservedly attracting considerable kudos during the 1990s. The GGC scheme was one of three golf course inspired projects that actually came about through a need to improve flood management (the irony!) during the early 2000s, with state and federal government funding being made available for schemes designed to reduce pressure on the inadequate stormwater infrastructure of the western suburbs. Glenelg, Royal Adelaide and The Grange golf clubs successfully applied for funds to construct similar ASR schemes, with Glenelg’s being the third of the trifecta to be constructed. Funding was split three ways with the state and federal governments, with the club’s investment being close to $1 million in the end. The concept of ASR involves; • The harvesting/collection of stormwater; • Treating it to a quality that meets Environmental Protection Agency (EPA) requirements for injection into the underlying aquifer; and • Storing it in the aquifer until it is required for re-use (i.e.: irrigation) In the case of Glenelg’s scheme, this involves; • Pumping water 350 metres from adjacent Brownhill Creek to the north eastern corner of the golf course. Brownhill Creek flows nearly continuously during winter, allowing the use of smaller pumps (compared to schemes that capture high flows immediately following storm events) yielding up to 60L/sec that can run continuously with adequate depth in the creek. The catchment area is approximately 120km2 and extends out to the Adelaide Hills; • Water is released into the first of three ‘cells’ of a 1.4 hectare constructed wetland, where it takes three days to flow through various bands of vegetation and open water to the end of Cell 3 (see photo page 40 for a system overview). • Water quality is monitored continuously at this point, and if it meets the necessary criteria, it is then pumped at up to 45L/sec over a distance of up to 850m to three injection bores, which double as extraction bores as well. Typically, the above takes place during winter, so the water is then stored in the aquifer until irrigation season commences. 38 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 Planning for the GGC scheme started in 2003, with construction carried out over the summer of 2008/09 and injection commencing 2011. The two years from completion of construction to commencing injection was necessary to allow the wetland plants to mature sufficiently to perform the required filtering of the stormwater. AQUIFERS AIN’T AQUIFERS The Adelaide Plains aquifer is particularly conducive to ASR, as it is quite stable and slow moving (apparently 5m/year), therefore as fresh water is injected it displaces the more saline groundwater water away from the bore, creating a ‘bubble’ of fresh water. This bubble then reduces in size as water is extracted during irrigation season, but over time, if more water is injected than extracted, the likelihood of extracting saline water decreases. Many aquifers are not suitable for ASR, with fractured rock systems often flowing rapidly, resulting in injected water moving off site and unable to be extracted. The initial modelling of the GGC system suggested up to 300 megalitres per year could be injected, which 20 years ago was around the annual water consumption for the course. However, the course redevelopment, conversion of turf species, refinements to management practices etc... have seen this figure reduced to around 200ML/year. As a result, there should be no problems injecting more water than is extracted, creating a surplus and larger bubble of fresh water to draw upon... theoretically! However, the reality to date has been slightly different. Since injection commenced, annual results have been; • 2010/11: 94ML • 2011/12: 85ML • 2012/13: 69ML • 2013/14: 80ML • 2014/15: 100ML • 2015/16: 125ML • 2016/17: 164ML • Note: May-October 2016 saw 223.8ML injected There have been a number of factors that have limited the yields against expectations; • Initial (Year 1 and 2) algae blooms resulted in plant debris blocking wetland pumps. • The injection of fresh water into the limestone aquifer has dissolved the underlying limestone, creating instability of the bore hole, restricting injectable and extractable flows and creating sediment that has blocked irrigation components and storage tanks. Initial levels set within wetland controls were inoperable with harvesting not being permitted as quickly as it should and being shut off earlier than required. Initial water quality threshold levels were inoperable, restricting the injected amount. • • Algal blooms, which blocked screens and restricted flow to the wetland pumps, were among a number of teething problems which had to be overcome early on in the system’s operation turf ryegrass Dura Trialled, tested, proven With Mediterranean germplasm for winter growth.

Further innovation from PGG Wrightson Turf pggwrightsonturf.com.au NOVEMBER-DECEMBER 2017 39 times, it has been the lack or inconsistency of rain that has limited injection volumes. Despite the hurdles, the scheme has been successful on a number of fronts; • The quality of water has assisted turf management with salinity levels typically around 500mg/L compared to natural ground water being between 1200 and 1900mg/L. • The wetlands themselves have enhanced the north eastern corner of the course, with holes 15, 16 and 17 benefiting directly. Bird life has increased and become more diverse with the introduction of the wetlands. • The interest in environmental management has resulted in numerous tours by local schools to educate them on what the club is doing. • Secured a relatively economical high quality water supply, with whole of production cost approximately $800/ML (compared to recycled water that is very variable but in excess of $1000/ML and potable water at $3500/ML). • 2016 demonstrated the capacity of the system to deliver in excess of the course’s annual water requirements, with 223ML able to be injected (even with some persistent limitations on injectable rates) due to some good rainfall in the catchment area. • Club pride in the scheme and visible education for the club on the value of water. The maintenance of the system has been greatly assisted by the design of the control system and its physical form which integrates with the course very well, especially now the plants have matured. • Weed control on banks is ongoing, but generally not too time-consuming (20-25 hours/year) • Monitoring of the system (water levels, valve status, pressure, water quality etc...) is automated with displays and readings fed back to the main office.

Isolated component failures. • • Flow and pressure settings within the system restricting rate of injection. • Rainfall patterns have at times resulted in initial ‘flushing’ of Brownhill Creek taking longer than expected for water quality to be deemed acceptable. • No rain! Many of these issues were teething problems that, whilst frustrating, were to be expected in a system as complex as this. A number of them have resulted in modifications to fittings, control locations, filtering components and even reviews of water quality targets. While it is true these have been frustrating at times, a longer term view of the value of the system helps to keep these in perspective as they have largely been ‘one-off’ fixes. In more recent 40 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 • Monthly compliance reporting on water levels and draw down readings. • Annual reporting on system changes, non­ conformances and usage requirements. • Annual pre-injection water quality testing (between $500 and $1500). • Annual removal of carp (currently approx. $5000) and regular removal of Typha spp from wetland beds. MORE IS BETTER? While the winter of 2016 was a great one for harvesting stormwater, it revealed another challenge for the club. With two other operating schemes within four kilometres of the course, and a third commencing across the road, the pressure created within the aquifer from constant injection saw bores of varying ages within neighbouring suburbs becoming artesian (flowing). The issue of responsibility was a contentious one, but the three existing operators and the regulators undertook a very productive, practical approach as everyone was learning from the experience. It has led to the development of some monitoring obligations for scheme operators to avoid the creation of artesian conditions into the future. The cost of power will also determine how much water is harvested into the future, with a surplus of injected water possibly being a luxury that cannot be afforded, even if the water is available. The current budgeted figure is $40,000 per annum for harvesting and injection power, plus an additional $80,000 for extraction and irrigation pump power. WHAT HAVE WE LEARNT? The ASR scheme at GGC has undoubtedly been a success, but it is clear that some lessons have been learned along the way. • Be involved in the planning process: Having a seat at the planning table from the outset enabled the club to articulate aspects that were critical for the long-term acceptance and management of the scheme. This could include the location of necessary hardware through to the shaping of wetlands (although it needs to be understood they are engineered to be functional, not beautiful). • Utilise local contractors wherever possible: Due to the nature of funding for the project, national tenders were called but fortunately our local electrical contractor was part of the successful submission. They knew our needs and the course very well, and hence were able to alert us to things that needed to be considered from a system control and power demand perspective. It also ensured great back­ up once the system was operational. • Ensure the club has a say in final acceptance of completed works: Provides greater assurance that components specified are actually utilised. Typha removal from the wetland beds is important to ensure the scheme’s designed flows are not compromised The ASR scheme has significantly improved the quality of Glenelg’s irrigation water with salinity levels typically around 500mg/L compared to the natural ground water which can be up to 1900mg/L NOVEMBER-DECEMBER 2017 41 seems quite localised, it needs to be understood that you could be impacting neighbouring properties. • Understand your licence agreement: Not that there is anything to be afraid of, but it pays to consider ‘what that phrase means’, even if it seems unlikely to occur. • Be patient: There will be glitches, headaches and problems. But they should be one-off issues that diminish over time, so keep the focus on the long-term benefits of the scheme. HAS IT ALL BEEN WORTH IT? The ASR scheme at Glenelg has settled in well, with performance becoming more reliable and predictable. It is now at an age where some refurbishment of vegetation and early infrastructure is now required. Planning has started for the replacement of things like cabinets and fittings that are weathering and pumps being assessed as to their likely lifespan to ensure future reliability. As well as the ASR scheme is performing, water supply is always going to be a competitive and at times volatile market in a climate such as Adelaide’s, so the option of accessing recycled water again as a back-up source is being considered. So has it all been worth it? Absolutely! The management and members responsible for undertaking the circa $1 million investment some 15 years ago should be justifiably proud of their decision, as the current members are of the end result. The course team have done an amazing job maintaining the system and also take pride in what the system represents. Long-term decisions can be the hardest to adopt, but everyone is confident the benefits will be with the club for a long time to come. WATER Glenelg’s ASR scheme has attracted plenty of interest from local schools and environmental management groups Right: Monitoring of the system (water levels, valve status, pressure, water quality etc...) is fully automated Bottom: Wetland cell one (adjacent to Glenelg’s 17th fairway) during initial construction and planting (below) and as it looks today (right) • Ensure you have remote control and visibility of the system: Monitoring of an ASR scheme is constant and a lot of time can be wasted travelling around the site checking performance, water levels etc... and then recording them. An appropriate control system will automate this process saving hundreds of hours each year. Investigate all the water source options, their costs and their likely social acceptance: ASR is a great option, but it isn’t the only one. In building a case for ASR, it is important to be mindful of the other options, their capital and maintenance costs and the likelihood that they will be available into the future. • • Understand your aquifer: Not all aquifers are suitable for ASR and some will behave differently once water is injected into them. Hydrogeologists can be very helpful in gaining an understanding of how your aquifer is going to respond to the injection of water and what the practical implications will be for the operator. • Ask questions and demand training: While we understand irrigation practices and principles, ASR is a different game and we shouldn’t be afraid to ask lots of questions to gain an understanding of how the system operates. Once constructed, it is likely you will be on your own to make it work, so you will want to have several staff members across the operational requirements of the system. • Think outside your boundaries: Although injection of water into a bore on your property 42 AUSTRALIAN TURFGRASS MANAGEMENT 1 Partnering with the <1 AGCSA Reward your passion for Turf ■ Buy Syngenta products and earn your way to the inaugural Australasian Turfgrass conference in Wellington, New Zealand.

AD 17-368 JOHN NEYLAN ATM’s expert columnist John eylan continues the discussion on perched water table greens construction and also ruminates about the role that cultural practices could play in assisting with Poa control in warm-season grasses. Above: Organic matter accumulation dramatically alters the moisture release characteristics of a greens construction sand What’s the right recipe? In a recent article by AGCSATech senior agronomist Bruce Macphee (ATM Volume 19.4 - ‘Understanding PWTs’, p38-41) the perched water table concept and moisture release curves were discussed. As on most occasions when this topic is discussed, it stimulates a wave of heated debate about the best sands and the best way to build a golf green. Is the science correct, is it actually relevant and is the laboratory theory replicated in the field? In short, the soil physics are sound but what happens in the field is still in doubt and there are still questions as to whether there is any relevance. The first perched water table greens came about through the work undertaken by the USGA Greens Section in the late 1950s and early 1960s and was in response to an increase in golf activity and the associated traffic and the failure of soil­ based greens to tolerate the wear. This story is very similar to the progression of Australian golf courses to move from loamy sand type golf greens to a more specific sand-based construction. The ‘Specifications for a Method of Putting Green Construction’ were first published in 1960 (USGA Greens Section Staff) and have formed the basis of the guidelines that have been refined over the past 57 years. The question in my mind has always been whether those that developed the USGA Greens Section Guidelines for greens construction actually had the perched water table as a key aspect in mind? In the 1960 guidelines the emphasis was on high permeability soils over an intermediate sand layer which was placed over a gravel layer and subsoil drains. The guidelines at that time emphasised the advantages of rapid drainage, good aeration, deep rooting, protection against diseases, protection against over-watering, protection against salt problems, a putting surface which holds a shot without being overly wet and one which resists pitting by golf balls. The guidelines emphasised the physical characteristics of the soil that are important for good turf growth and are still true today. That is, on a compacted sample the total porosity is a minimum of 33 per cent v/v, aeration porosity 12-18 per cent v/v and capillary porosity 15-21 per cent v/v and a 44 AUSTRALIAN TURFGRASS MANAGEMENT saturated conductivity of 150-460mm/hr. In the 1960 guidelines there was no mention of the perching affect at the gravel sand interface. Marvin Ferguson (former National Director, USGA Green Section) was one of the drivers of the guidelines for greens construction and in an article in 1983 he discussed the challenges of managing sand profiles. He notes that the doughtiness of sands could be mostly overcome by the use of a gravel blanket at a depth of 300mm where the gravel provides rapid drainage and forms the perched water table which provides a reservoir of available water. This concept seems to have come about through research by Miller and Bunger (1963), Dougrameji (1965) and Unger (1971) where it was identified that having a coarse-textured strata within the soil profile will result in a “perched water table” and increase the water retention of the entire profile. The 1989 specifications stated that the coarse sand layer was an integral part of the perched water table concept and seems to have more formally integrated this phenomenon into the specifications. In Hummel’s (1993) detailed review of the greens specification, the need for the intermediate sand layer was questioned from a perched water table perspective. Hummel (1993) cited research where providing that the correct gravel size was used it would both prevent the migration of fine soil particles as well as form a perched water table. While the perched water table and its importance is recognised within the USGA guidelines, the development of the moisture release curve (MRC) is not documented and is not related to the depth of the rootzone layer. All measurements are undertaken at a standard tension of 300mm and presumes a rootzone depth of 300mm. McIntyre and Jakobsen (1998) and McIntyre et.al. (2007) have used the MRC as a method of determining the optimum depth of the sand rootzone so that the root system of the turf has optimum access to the water stored in the capillary fringe or perched water table. Consequently, the optimum depth of the rootzone sand becomes specific to that particular sand and as a generalisation is less than the standard depth of 300mm used by the USGA Green Section guidelines. The only question around the McIntyre et.al. (2007) method is the reliance on laboratory tests to provide such a specific rootzone depth. In particular, the rationale of adding 100mm to the top of the perched water table to give roots access to sufficient water to reach the top of the perched water table is somewhat questionable. The theory around the perching or accumulation of water at the interface between contrasting layers (e.g. sand over gravel) is well proven. The question then becomes whether the concept holds true and predictable under field conditions. The research that I undertook into the characteristics of various sands for greens construction (ATM Volume 16.5 - ‘Hard Figure 1: Soil moisture content at various depths in a perched water table putting green 0 5 Volumetric Water Content (%v/v) 10 20 15 25 30 Figure 1.

The results of laboratory analysis, in particular the MRC, has always been a constant source of NOVEMBER-DECEMBER 2017 45 JOHN NEYLAN How long did it take for this mature Poa plant to get to this size? ◄ With our knowledge of soil physics, greens construction can be more innovative and site specific. The key is testing materials and understanding their characteristics, having a strict testing regime during construction, good construction methodology and an appropriate maintenance regime. debate and in particular how does the laboratory data relate to the field experience. Once there is a vegetation cover and plant roots, the interactions become more complex and the laboratory determined characteristics can alter markedly. With the sand research project and my field observations of golf greens, there is often a disparity between the laboratory results and the field observations. In my field observations of having taken many core samples from sand profiles, very few of them have the moisture profile as determined in the laboratory. An example of this is provided in Figure 1 and should be compared with the laboratory-generated curve (Figure 4). There are several reasons for this; • Thatch and organic matter accumulation modifies the hydraulics of the profile keeping more moisture trapped at the surface; • Rarely does irrigation or rainfall on a well grassed green or sportsfield saturate the entire profile, allowing the perching effect to be recharged or maintained; and • Turf management is very much about surface management and root systems are not deep enough to draw moisture from the lower layers. A compilation of soil moisture data collected from many different golf greens is detailed in Figure 2. The measurements were taken in the top 7.6cm of the profile (includes turf and organic matter layer) and then the underlying sand layer using a FieldScout™ TDR moisture probe. As can be seen, the difference is considerable with the surface layer having 24-79 per cent more moisture than the underlying sand. This immediately demonstrates that the dynamics of the MRC for a sand at field capacity is altered dramatically by the turf layer. This occurrence then often dictates how the greens are managed in terms of irrigation and rarely is the entire profile re-wetted and the perched water table restored. With the sand research project, I sampled each of the different sand profiles to determine what the moisture profile would be following saturation and drainage. My principle interest was to see how closely the moisture profile mimicked the laboratory results. The profiles were saturated by capillary rise and then irrigated until water was running from the drainage outlet. Once the profiles had drained, samples were taken at 5cm increments and the gravimetric water content determined. The results for several sands (Table 1) are detailed in Figure 3 and are compared to a MRC generated in the laboratory for FS1 and MS1 (Figure 4). In the laboratory-generated MRC, note TABLE 1: SUMMARY OF CHARACTERISTICS FOR SANDS USED IN THE Sieve size (mm) MBS <0.053 0.8 Fineness modulus 0.94 Cu = D60/D10 1.53 Description** U/F Infiltration rate (mm/hr) 450 MOISTURE PROFILE EXPERIMENT % Particles retained* FS1 2.8 0.94 2.35 WG/F 256 MS1 0.7 0.96 2.06 WG/F 869 PGS 0.5 0.91 1.88 MU/F 223 *Sand gradings done by wet sieve analysis **U = uniform, MU = moderately uniform, F = fine (68 - 825) (150-330) (217-266) (750- 1061) (206 - 397) (963- 1147) 46 AUSTRALIAN TURFGRASS VIENT 19.6 FS2 2.2 0.87 1.62 MU/F 296 MS2 0.5 0.97 2.2 WG/F 1041 the difference in the height of the capillary fringe for the two sands. That is, the capillary fringe is considerably higher for the finer FS1 sand compared to the coarser MS1 sand. The final question around the perched water table golf green is what happens when it is not flat. Once a green has undulations in the surface, the forces of gravity start to direct water to the low point at the detriment of the perching effect in the more elevated sections of the green. Prettyman and McCoy (1999) demonstrated that when the green has undulating areas, moisture extremes in the rootzone often lead to turfgrass decline. In my field observations, it is not uncommon to find saturated conditions and black layer in the low points of these undulations. It has also been observed on a sand-based racetrack with a substantial slope on the turns that the inside portion (low point) of the track becomes saturated and the outer section dry. Frank et. Al. (2005) went to the extreme of building a profile with a variable rootzone depth on a sloping profile. The depth of the rootzone varied from 200mm at the high points and 400mm in the low points. In general, their research found that in areas of undulation the uniform rootzone depth can result in moisture extremes at the different elevations and that modifying the depth of the sand rootzone improved the uniformity of volumetric water content across the surface of an undulating putting green. In recent times there has been a question around the applicability of the USGA/perched water table method of greens construction and its relationship to firm and fast greens. Interestingly, the playing characteristics of the putting surface don’t appear to have been studied in any great detail as it relates to the firmness of the putting surface. Ferguson (1983) did make mention of this aspect in his article in that there is one major objective - the green must provide a satisfactory surface for playing the game. “It must hold a well-played approach shot without being severely marked and it must allow a putt to roll true”. In addition to these needs of the plant, a soil for putting greens must also be stable and firm. While Ferguson (1983) made these comments there was no further discussion regarding the physical attributes that provide stability and firmness. So where are we at? The perched water table profile, the USGA profile, the California method of greens construction and, on the right site, the ‘push up’ green, all have validity. There is no ‘absolute way’ to build a sand-based profile. In an article written by world-renowned golf course architect Mike Hurdzan (2000), he makes the comment that he believes that there isn’t any one best way to build a green. He makes the observation that the preferred method is the one best suited to any given combination of microclimate, irrigation water source, turfgrass, construction budget, A complete new range with advanced technologies HtPro TriSmart Introducing a new range of specialist wetting agents from ICL; H2Pro TriSmart, H2Pro FlowSmart and H2Pro AquaSmart.

However, what he emphasises, as do many other researchers on this topic, is that testing and selecting the most appropriate sands and gravels is paramount. In conclusion, the perched water table greens profile is well proven providing that the correct sands and gravels are selected and there has been good construction methodology employed. There is no doubt that it is a good recipe with a predictable performance. However, with our knowledge of soil physics, greens construction can be more innovative and site specific, particularly when using native sands or searching for other characteristics such as surface firmness. The key is testing materials and understanding their characteristics, having a strict testing regime during construction, good construction methodology and, of course, an appropriate maintenance regime. POA ANNUA SEEDLINGS - ARE WE KEEPING THEM ALIVE? In keeping with my interest (and some may say obsession) with Poa annua, I continue to make observations regarding its characteristics and some of the factors that may be making it difficult to control. Over the past 12 months, since the herbicide resistance testing was commenced, I have taken core samples from numerous locations where there has been recorded herbicide resistance. This has been primarily to determine the size of the seed bank but also to observe the growth characteristics of the plants and their mature plant form and whether this relates in any way to controlling it. The size of the Poa seed bank is considerable with 1500 to 20,000 seedlings per square metre recorded (average about 7500) with about 90 per cent of the population occurring in the thatch layer. Clearly there is a large potential reserve of new plants with the possibility that a high proportion of the population will have herbicide resistance. The second aspect is that it takes about two weeks for germination to occur, irrespective of where the samples come from (including different golf courses and different states) and then over the next 4-6 weeks the seedlings do not progress particularly quickly from the single leaf stage. From six weeks onwards, providing that the conditions are favourable, there is an increase in tiller numbers at which time the plant is relatively large and would be noticeable within a turf sward. So what is the relevance? It has become apparent that many golf courses are at a very high level of conditioning and in particular the presentation of the fairways. The fairways are being watered and fertilised more regularly which is going to favour the survival of Poa annua, even during periods of high stress. In the early days of using couch in the southern states, water was either at a premium or the irrigation systems were incapable of irrigating frequently and therefore there was a natural decline of the Poa annua population as the fairways dried out over summer. Given the mild spring/summer experienced in SE Australia in 2016/17 and the high aesthetic presentation of fairways, there is a good chance that these inconspicuous plants survived through the summer and then matured in the autumn/winter period. So the question is what are the ramifications? If these plants are present they will be well protected by the couch from herbicides and possibly heat and moisture stress. If they survive the summer, they are likely to be unaffected by the late summer/early autumn application of pre-emergent herbicides. So what to do? The obvious tactic is to review the irrigation and fertilising practices on fairways. While the visual aesthetics have some importance, the traditional summer couch fairways have been one where the turf has good density, provides a great golfing surface but is an off-green colour. Watering deeply once every two weeks or so will be sufficient for keeping couch strong and healthy while placing the Poa annua under greater stress. The heat and drought resistance of couch was why it was planted in the first place and these attributes need to be exploited as a means of controlling Poa annua seedlings. With all the discussions, forums and workshops held over the past 12 months, it is obvious that Poa annua control is more than what herbicide we can throw at it. It requires a multi-faceted approach including cultural practices, as well as the strategic use of herbicides. So now the question is, if good control is to be achieved are we prepared to revert to some older practices now that an expectation has been created? 48 AUSTRALIAN TURFGRASS MANAGEMENT ' PERFECTION MATTER OF PRECISION 'The Jacobsen LF570 is the perfect fairway mower for our course.

Nick Kinley, Course Superintendent, Hartfield Golf Club www.jacobsen.com tuiitter^ YoufilTO fig) ATM/HartfieldGC/11/2017 RESEARCH At the recent International Turfgrass Research Conference in New Jersey, Penn State University Professor Mike Fidanza presented a paper documenting the changes in USGA rootzone properties in ultradwarf bermudagrass greens over a period of eight years. The new ultradwarf couchgrass hybrids, such as Tifeagle (pictured here at RACV Royal Pines on the Gold Coast), can provide superior playing surfaces, but they require close monitoring and management of thatch, organic matter levels and saturated hydraulic conductivity The USGA Green Section has developed standardised methods or specifications of putting green construction to provide uniform playability and performance. The principle factors in the specifications address rootzone parameters of particle size distribution, profile depth, and to a less detailed extent, organic matter (OM) content (Beard, 1973), with the system widely adapted around the world (Aldous, 2011). However, it is well recognised that the chemical and physical rootzone properties of greens change from the day the green is established (Lewis et al., 2010; Oatis, 2010; Schmid et al., 2014). Chemical properties can be managed and adjusted (McCarty, 2004), but physical properties such as particle size, pore space distribution, thatch accumulation and soil OM content are more difficult to modify (Lowe, 2014; Waddington et al., 1992). Typically, cultivation methods such as verticutting and hollowcore aerification are employed to address those physical problems, but these methods can be damaging to the turfgrass surface and temporarily affect play (Moeller, 2010). Consequently, golf course superintendents must justify the need for such measures (Gross, 2013) and having quantitative information on green rootzone properties can help with this justification. Thatch is defined as a tightly intermingled layer of living and dead stems, leaves and roots that accumulate between the turfgrass and the soil below (Turgeon, 2011). Thatch is a normal component of an actively growing turf and as long as it is not too thick it can increase the resilience of the turf to heavy traffic (Moeller and Bigelow, 2007). For example, thatch develops more readily on high- maintenance lawns than on low-maintenance lawns and is typical in turfgrass swards containing species that spread by stolons or rhizomes (Turgeon, 2011). Thatch and OM can accumulate rapidly, especially when ultradwarf bermudagrass hybrids are used (McCarty, 2004). Additionally, permeability or the ability of water to move through the soil can decrease in response to OM accumulation (Lewis et al., 2010; Lowe, 2014; Waddington et al., 1992). For example, new Tifeagle ultradwarf bermudagrass USGA-specification greens were established on a golf course in southern Florida in the summer of 2003. In autumn 2004, OM in the 2.5cm to 7.5cm rootzone layer averaged 3 per cent (by weight) over the two greens measured, and saturated hydraulic conductivity (Ksat) averaged 50cm/hr. One year later in autumn 2005, OM averaged 5.5 per cent, or an 83 per cent increase, and Ksat averaged 7.5cm/hr, or an 85 per cent decrease. This initial observation led us to conduct this case study. MATERIALS AND METHODS Soil samples were collected to quantify thatch, OM accumulation, and Ksat of two ultradwarf bermudagrass USGA-specification greens on each of four southern Florida golf courses (eight greens in total) over a period of eight years from 2006 to 2013. Rootzone samples were generally extracted in the spring, just prior to the start of the early-summer cultivation programme and again in autumn after the completion of late-summer cultivation. The cultivation programme generally consisted of three to four hollow-tine aerifications spaced 5.1cm apart to a depth of 7.6cm and scheduled monthly from mid-June through mid-September. These cultivation procedures included core removal and sand topdressing to fill the holes (Foy, 2014; Guertal and White, 1998). 50 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 The greens received multiple verticuttings during the summer months (Lowe, 2013). Less aggressive verticutting was used in the winter months, along with periodic solid tine and/or hydroject aerification, as well as light sand topdressings (Lowe, 2012). Overall, the greens were subjected to normal or routine maintenance for ultradwarf bermudagrass (McCarty, 2004). For thatch and Ksat assessment, four relatively undisturbed rootzone cores measuring 5cm diameter by 7.5cm deep were collected in PVC pipe cylinders from two greens each and on each of four golf courses in southern Florida in the spring and autumn from October 2006 to October 2013 for thatch and from April 2009 to October 2013 for Ksat. For determination of OM content in thatch and stained rootzone layers, eight cores, 1.9cm in diameter by ~20cm deep, were collected using a standard soil probe from two greens each and on each of those four southern Florida golf courses during each spring and autumn sampling time from April 2008 to October 2013. Rootzone samples were generally extracted in the spring, just prior to the start of the early-summer cultivation programme, and again in the autumn after the completion of late- summer cultivation. THATCH The 1.9cm diameter rootzone cores were divided into thatch, stained and original sections (see photo Two examples within the soil samplers - thatch layer (top), organic matter-stained layer (centre) and original rootzone layer (bottom) in a rootzone core taken from a Tifeagle green in southern Florida above). The verdure and thatch layer, which hereafter will be termed ‘thatch’ (even though the term ‘mat’ may be more appropriate), was separated from the lower OM stained layer subjectively by cutting with a knife at the depth where resistance to cutting decreased substantially. Within the context of this case study, the stained layer is defined as a zone of OM deposition that, over time, differs from the original rootzone mix and can be delineated visually by colour, as well as physical resistance. The thatch depth or thickness was measured on each sample from spring 2006 to autumn 2013 and the thatch was retained. The depth or thickness of the OM-stained layer below the thatch was also measured from spring 2006 to david golf IMPROVING THE QUALITY OF YOUR TURF... one drop at a time!

Periodically, material from below the stained layer was collected to represent the original rootzone material used to construct the greens. ORGANIC MATTER The OM content was determined on the thatch, OM-stained layer and underlying rootzone material as percentage by weight loss after ignition. After ashing, particle sizes were determined on the remaining material by screening through a nest of sieves. SATURATED HYDRAULIC CONDUCTIVITY The Ksat was measured on the 5cm-diameter cores, which contained both turfgrass and thatch, and followed the procedures described by the USGA. However, it should be noted that the USGA procedures were designed to predict the suitability of rootzone mixtures for green construction, and not for analysing undisturbed cores from existing greens. For example, the procedure calls for compacting the mixture prior to analysis. For the undisturbed cores in this investigation, laboratory compaction did not seem appropriate and was not conducted. The USGA Ksat procedure does not assume that turf is present, as it was in the 5cm-diameter cores. In some cases, after conducting the Ksat analyses, eight 0.78cm-diameter holes at 2.5cm deep were made in each core with a cork borer and Ksat was measured again to gauge the effect of the thatch layer on Ksat (Figure 1). The initial Ksat reflects the conductivity of an undisturbed core; however, the thatch coring procedure was employed Top: Figure 1. If an increase in Ksat was observed due to holes through the thatch, relative to the initial Ksat determination, and the effect was most pronounced in samples having an initial low Ksat (graph to the left), it is assumed that thatch has a strong influence on Ksat. If there is little relationship between changes in Ksat due to holes and the initial Ksat (graph on the right), it is assumed that the thatch is not greatly controlling Ksat and suggests that the rootzone below the thatch may be more influential Above: An undisturbed core taken from a golf green with seven 0.80-cm-diameter holes drilled through the thatch layer to gauge the effect of thatch on saturated hydraulic conductivity 52 AUSTRALIAN TURFGRASS MANAGEMENT 1 f to provide further insight into Ksat of suspected restrictive layers (Figure 1). For example, after thatch coring, if Ksat was increased, then the restrictive layer was thatch, and therefore a recommendation would be to encourage cultivation (i.e., shallow coring, verticutting, etc.) to relieve thatch layer conductivity restrictions. After thatch coring, if there was slight or no Ksat improvement, then cultivation would be recommended to improve conductivity below the thatch layer and deeper in the soil rootzone. RESULTS THATCH Over the eight year assessment, the measured depth of thatch stabilised at 2.5cm or less, whereas the OM-stained layer increased in thickness to nearly 10cm (Figure 2). Initially, the rootzone below the thatch probably becomes stained with OM as roots extend into it, senesce and decompose to form humus. Over time, however, the stained layer likely increases in thickness, not because of deeper rooting, but rather because of increasing rootzone thickness due to repeated sand topdressings. The green’s turfgrass surface grows upward and the lower regions of thatch decompose to contribute humus to the underlying stained layer (see photo opposite page). Thus, the stained layer increased in thickness over time in the rootzones of these greens (Figure 2). ORGANIC MATTER The OM content in the thatch and stained layers generally fluctuated over the year (Figure 3, p54) in response to the cultivation programme (i.e., verticutting and hollow-core aerification). In both layers, the OM content was greater in the spring than in the autumn. This occurred despite the fact that the warm-season turfgrass growth is much greater in the summer than in the winter, because superintendents in Florida typically conduct active cultivation programmes in the summer with the goal of removing excess OM or preventing excess OM accumulation. The increase in OM over winter, even with reduced turfgrass growth, indicates that OM ‘buildup’ would occur over time if an aggressive OM removal programme was not conducted. As was shown in Figure 2, the OM-stained layer increased in thickness overtime. However, if the OM content is stable and relatively low, as was the case with all greens measured on all four golf courses (Figure 3), then the increased thickness should not cause a significant reduction in soil porosity. Of note, OM content of the stained layer exhibited a slight decrease over time (Figure 3), but the minimum OM content of thatch showed a slight increase Figure 2. Depth of thatch and thickness of the organic matter-stained layer measured from October 2006 to October 2013, representing a spring and autumn assessment each year Example of upward rootzone growth of a sand-based ultradwarf bermudagrass golf green due to repeated sand topdressings. At this particular course, the superintendent used black sand topdressing during the winter, making it possible to observe the effect of repeated topdressings at 9 and 12 months later over time (Figure 3). Thus, cultivation programmes were successful in managing OM content in the stained layer, but more cultivation may be needed to decrease OM content in the thatch layer. These observations reveal that the depth (or thickness) of the stained layer increases over time, and OM content is diluted as topdressing sand is included in the original rootzone mix. Notably, with cultivation, some OM is removed with the expelled cores and the empty coring holes are filled by lower- OM-content topdressing sand, which most likely results in the stain layer having a stable OM content. Also of note, OM content in thatch at about the 1cm depth increased over time, suggesting that more topdressing sand and/or cultivation is needed to reduce thatch OM content. SATURATED HYDRAULIC CONDUCTIVITY Ksat also fluctuated over the seasons. The Ksat was typically lower in the spring and higher in the autumn, which could be attributed to summer cultivation practices that removed OM both in the thatch and in the underlying stained layer. Increased Ksat is indicative of increased rootzone porosity, which favours movement of not only water but also oxygen into the rootzone and carbon dioxide out of the rootzone (Waddington et al., 1992). The Ksat data was subjected to CV analysis which is a statistical measurement of the variability among observations and is expressed as a percentage. A CV for Ksat indicates the uniformity of the porosity in a green’s rootzone and therefore uniformity for an entire green would be considered a favourable trait (Lowe, 2012). As illustrated over time, the CV was generally greater in the spring than Two products to combat the toughest conditions From the trees back to the turf.

Thus, summer cultivations appear to improve green uniformity, as indicated by the CV. DISCUSSION To promote permeability in a USGA-specification ultradwarf bermudagrass golf course green, either rootzone particle size distribution should be uniform throughout the profile or the surface soil layers should be coarser than the underlying soil layers. A decline in percolation results from the loss of macropore space when the finer sand particles in the topdressing accumulate toward the surface (Moeller and Bigelow, 2007). This ‘finer’ layer restricts drainage and air movement (Hillel, 1980), resulting in a softer, wetter surface more prone to scalping (Hartwiger and Nicoludis, 2017; Moeller and Lowe, 2016). Particularly when ultradwarf bermudagrasses are used, superintendents may frequently use finer sands for topdressing to facilitate movement of the grains into the tight turf canopy that is associated with these grasses. The original rootzone may meet USGA specifications at the time of green construction and installation, but over time, coarse sand of the rootzone decreases toward the surface, whereas the fine and very fine sands increase or accumulate (Table 1). Therefore, the surface or upper rootzone layer becomes out of compliance with USGA specifications. Of note, particle size distribution of sand topdressing at all four golf courses was within USGA-specifications guidelines (Table 1). The rootzones measured in this study revealed that the surface contained <60 per cent coarse and medium sand and exceeded USGA specifications for fine and very fine sand (Table 1). This condition restricts permeability because of the increase in finer sand particles, which leads to reduced macropore space through which air and water movement is best facilitated (Beard, 1973). To help overcome this condition, a superintendent can employ strategies to penetrate coarse sand into and through the turf canopy to reach the thatch or rootzone (McCarty. 2004). Some examples are the use of USGA specification sand, or a coarser-sized sand, after deep verticutting and also for filling core holes, and the use of dry sand applied to dry turf for routine topdressings to use the coarsest sand possible without excessive mower pick up (McCarty, 2004). In conclusion, superintendents who routinely monitor OM and Ksat on their ultradwarf bermudagrass USGA-specification sand-based greens can use data on thatch and OM-stained layer thickness, OM content and Ksat in the spring to show their stakeholders why summer cultivations will be necessary, and in the autumn to illustrate what has been achieved by the summer cultivation programme. Such data should help overcome resistance among those stakeholders and decision makers to conducting verticutting and aerification practices on greens. The data can also provide information to determine how aggressive the cultivation programmes need to be. ACKNOWLEDGEMENTS ATM is grateful to Prof. Mike Fidanza and co-authors George H.

Above: The way companies deal with managing the performance of their team is changing and it is important to be across these in order to get the best out of your employees Often at this time of year, managers are starting to plan for their employees’ performance reviews. A recent Australian workplace survey on performance reviews shows that most managers dread them, seeing them as time-consuming and overall not very useful. Employees, on the other hand, find them frustrating, a waste of time and can become quite anxious at the thought of receiving negative feedback. The survey also found that more than half of a performance rating has to do with the personality traits of the person conducting the review, not of the person being rated, resulting in a very subjective, biased and unfair rating of an employee. Another survey, conducted by PricewaterhouseCoopers, shows that 96 per cent of ASX companies have either recently changed or are planning significant changes to their performance management system in the next 12-18 months. Traditionally, annual reviews have focused on past performance, however, this thinking has now changed with a shift of focus to the future. Here are a few examples of how some global companies have changed their review system, with one linked to salary increases and one based on performance. As an aside, many companies do not link salary increases to performance reviews. Accenture, the strategy, technology and digital consulting firm known for its traditional corporate culture, has completely discarded its annual reviews, replacing the process with a system where managers give feedback on a more regular basis. Accenture has implemented a more informal ‘check­ in’ process that takes place throughout the year, 56 AUSTRALIAN TURFGRASS MANAGEMENT : 9.6 with employees receiving regular feedback on what they’re currently working on. Accounting firm Deloitte has replaced its laborious annual review process with four questions done after every project or major task. On a 1-5 scale, managers write down how strongly they agree with two assertions: • “Given what I know of this person’s performance, and if it were my money, I would award this person the highest possible compensation increase and bonus.” “Given what I know of this person’s performance, I would always want him or her on my team.” They also answer ‘yes’ or ‘no’ to: “This person is at risk for low performance.” “This person is ready for promotion.” The answers are used not only to make decisions about who should be promoted in the future or how much they should be paid, but to influence how the company helps rising stars advance and help the troubled ones get back on track. According to managers at Deloitte, “In effect, we are asking our team leaders what they would do with each team member rather than what they think of that individual.” • • • Microsoft has also discarded its performance review system. The company’s new approach to performance and development is designed to promote new levels of teamwork and agility that have an impact on the goals of the business. The key elements of Microsoft’s approach include: • More emphasis on teamwork and collaboration; • More emphasis on employee growth and development; and • No more scoring or rating scales. REVIEWING PERFORMANCE You don’t have to be an Accenture with 330,000 employees or a multinational technology giant like Microsoft to look at changing your review process. At the end of the day you are dealing with people. The PGA of Australia has followed these global trends and in 2015 changed its performance review process. To begin, we eliminated the six monthly reviews and redesigned our annual reviews. Our focus is now firmly on the future rather than on the past 12 months. Here is an overview of our new process... The manager emails an employee self­ assessment template to their team members a couple of weeks prior to the meeting. The employee self-assessment template has two parts: • The first part is divided into three columns - responsibilities, KPI’s achieved/not achieved and employee comments. Firstly, team members need to review and update their position description and then use their PD’s to fill in the first two columns. • The second part is the ‘future state’. In this section, team members briefly bullet point projects/tasks they would like achieve or work on the following year, list development or training they would like to undertake and add any other points they would like to discuss with their manager. The self-assessment is then emailed back to the manager prior the meeting. The manager’s template also has two parts. • The first part is divided into three sections - tasks and responsibilities (the tasks and areas of responsibility critical for the success of the position), outcomes (describes what doing the job well looks like) and individual and team objectives (clearly identifies whether the tasks are to be done individually or with the team, and the timeframes, if applicable). • The second part is the ‘development plan’ which is divided into two sections - ‘areas of development’ (what they’re doing well or where they need to improve with tasks, skills or behaviours) and ‘actions’ (activities that will assist in development - this could be class training, on-the-job training or coaching). The templates are designed to facilitate a two- way flow of conversation. The individual and team objective column is the ‘what’ and the development plan is the ‘how’. Managers are encouraged to discuss with their team members how their individual goals or objectives contribute overall to the company. It is motivational to let employees know how their individual effort and performance contributes to the broader organisational goals and vision. If you are a manager, the three key areas to focus on are: • Linking goals/objectives to company priorities; • Helping team members apply new and critical skills in their roles; and • Shifting the focus to performance, not ratings. As a guide, a performance review meeting should go for no more than an hour. Spend the first 15 minutes on past performance and the rest on the future. Ensure absolute clarity on future performance expectations. Shift from a focus on employee management to a focus on fuelling employee performance. It is also important to always manage at the time and don’t leave it for the performance review meeting. Effective managers provide specific feedback on a daily or weekly basis. The more you can get the team member to evaluate their performance the better. Some questions you can use are; • How do you think you went? • What do you think you did well? • What would you do differently next time?

Pictured is the 17th The weather and climate is always a great leveller for a superintendent. How has Mother Nature treated you in recent times? Since I started my turf career most years have been different climatically. In 2012 we went through a one-in-twenty-year flood which inundated the course for two weeks. Working through that was an interesting experience. Then there are the hot and dry summers with weeks of 40 degree temperatures and having to start watering at 2am working split shifts! Some winters it can get that wet you can’t leave the shed! Mother Nature definitely keeps you on your toes. Are expectations of course presentation and conditioning any less than that placed on your metropolitan counterparts? I think all courses have their own expectations. No doubt metropolitan courses are heightened, but expectation plays its part in driving us to deliver the best course possible week in, week out. Your expectations must, however, align with the budget and man hours you have at your disposal. Do you have to be more resourceful as a regional­ based superintendent? I don’t think you have to be more resourceful at a regional club, but definitely in a small one you do. Not having a course mechanic means over the years learning how to fix issues and problem solve as well. Sure, at times some problems are too big, but most issues can be fixed 64 AUSTRALIAN TURFGRASS MANAGEMENT 1 in-house. That also goes for large irrigation issues and leaks. If you could change one thing about your job as a regional superintendent what would it be and why? Not much. We have a great little club that members enjoy, the majority of whom have been here 20 to 30 years and can see and understand how far this place has come. What have you got in your shed? Toro 5610, Toro 6500, 2 x Greensmaster 3250s, Kubota F2400 front deck, Smooth Roller, Flex 21 walk-behind, John Deere Aercore 800, Massey Ferguson Tractor, 400L Hardi spray tank, John Deere tractor, Kubota front end loader, Trimax finishing mower, Queen bowling green mower, 2 x old Queen mowers with fatboy reel and groomer reel. Any interesting/old pieces of machinery you keep alive through necessity? We only just recently gave away our old buck rake as a garden ornament (it had seen better days). It hasn’t been used much in my time, but I have seen it in action a few times and it does a good job raking under the big gums. The old guys at the club swear by it! Do you think regional/country superintendents have a better work-life balance than their metro counterparts? I can’t speak on behalf of metro supers because I haven’t been one, but I think I have a pretty good work-life balance. Living only minutes from work makes the trip on weekends to check everything out quick and easy. In saying that, I do spend long hours at work through summer due to our irrigation system, but hopefully that problem will be fixed soon enough. What is the most challenging aspect of a superintendent’s role today? Not being in a management position before this, it’s something I’m learning along the way, especially things like club politics and different personalities. Being able to keep up with all the recordkeeping, paperwork and WHS demands, as well as delivering the course week to week, can be a real juggling act. I also recently hired my first apprentice and now being a teacher is a new challenge but one I’m enjoying. What gives you the most job satisfaction? Seeing members and visitors enjoying the golf course and playing on the bowling greens. Seeing my staff grow into their job and become passionate about what they do and watching the club grow. Most pleasing/rewarding moment during your time as NGBC superintendent? I would say Pro- Am day. Spending weeks of hard work leading up to the event and hopefully delivering a course for professionals and members to enjoy on one of the most important days for the club.

This makes the added oxygen very stable in solution for extended periods of time. Avondale’s injection unit, which was commissioned on 29 September, is located adjacent to a 500,000L water storage tank. A small pump removes the water from the tank, passes it through the injection unit on its way back to the storage tank. According to Warwick, the dissolved oxygen levels in the tank went from 2.9ppm on the day of commissioning the unit to 28.4ppm after 12 hours of treatment. “From all the research I’ve done, I can’t believe that the subject of dissolved oxygen (DO) is not known about in turf to any great degree,” says Warwick. “I’ve worked closely with the staff from Nano Bubble Technologies for the past nine months and each time we converse I learn something new. I’m still staggered that the problem of poor DO concentration is only just coming to our attention as an industry worldwide. “While the trials we are conducting are still in their early days and more time is needed to see clearer trends, the early results look extremely promising. Data to date indicate a huge improvement in root mass and reduction in spiral nematode numbers, and based on other observations we are hoping to expand our trials.” vondale Golf Club in Sydney’s northern suburbs has become the first golf club in the world to install a Nano Bubble Technologies injection unit. As showcased at the recent Australian Turfgrass Conference on the Sunshine Coast, Melbourne­ based Nano Bubble Technologies has developed a patent-pending nano-bubble generator that permits the infusion of various gases (such as oxygen, ozone, air etc...) as nano bubbles into liquid at extremely high concentrations. Nano bubbles are essentially nano-scopic gas-filled cavities in aqueous solution, providing super­ saturated oxygenated water which has a range of applications across various industries. Over the past nine months, Avondale Golf Club has been undertaking small scale trials using nano bubble water in a turf situation and the results have been extremely promising according to course superintendent David Warwick. As a result, the club granted approval for a trial injection unit to be installed on course. Trials to date at Avondale have looked at using nano bubble water to determine its impact on bentgrass root growth and also on reducing nematode counts. These are ongoing and Warwick is hoping to expand the scope to include trials on the effects it has on reducing black layer and combatting BF1 fairway patch disease. In addition, Warwick has also observed that the nano bubble water appears to boost the properties of soil wetting agents and has assisted with the efficacy of commercial products to treat stem weevil. The Nano Bubble Technologies system works by compressing air, extracting out all the pollutants and removing the nitrogen component which leaves 96.3 per cent pure oxygen. This is then injected into the irrigation water through patented technology which creates the nano bubbles. Around 250 million nano bubbles can be injected into every millilitre of liquid per single pass through the company’s injection system.

The R50-11 offers a number of enhanced features focused on productivity, reliability and reduced maintenance. According to Tru-Turf managing director Ray Dufty, the R50-11 greens roller is the perfect tool for prestige golf greens that require a true, smooth and grass clipping free surface. Driven by a flexible, full width contour-following drive roller and equipped with Tru-Turf’s patented triple offset smoothing rollers, following contours is made simple with the R50-11. Combine this with overlapping roller heads and new self-cleaning smoothing roller system, superintendents will achieve a true, smooth 50-inch (1.27m) wide roll on the most contoured greens without leaving gaps, clippings or line crease marks. “Because we are always evolving and listening to our market, we have incorporated a new quick release design that allows for a fast, safe and tool- free transition between brushing, spiking or slicing attachments,” says Dufty. “This allows course staff to spend less time in the workshop and more time on the greens.” While other greens rolling machines rely on weight to heavily compress the playing surface, Dufty says Tru-Turf’s lightweight rollers “create fast, true surfaces, without compacting the soil beneath, resulting in healthier greens”. The R50-11 is powered by a 6.5hp Honda petrol engine with an operating speed up to 15kph. To watch the R50-11 greens roller video, visit the Tru- Turf YouTube channel or visit www.truturf.com. Tru-Turf’s R50-11 greens roller offers a number of enhanced features focused on productivity, reliability and reduced maintenance COMPASS SETS NEW DIRECTION IN FUNGICIDE MARKET AGCSA Gold Partner Nuturf Australia has launched Compass fungicide into the Australian turf management market. Compass is a new multi­ site contact fungicide containing 500g/L of the active ingredient fluazinam and is registered to provide powerful contact activity on a range of turf diseases including dollar spot, helminthosporium, anthracnose and grey leaf spot. \ AQUATROLS® IS THE WORLD LEADER IN SOIL SURFACTANTS 1 o t 'dBBLK?’ I ' ' ’ AND WETJING AGENTS .

According to Nuturf, it has no known resistance and due to its multi-site mode of action has a very low risk of developing resistance. According to Nuturf business manager Peter Schumacher, Compass will add value to fungicide programmes in a number of areas including; • Dollar spot control. Research in Australia and in the university system in the US, shows that fluazinam is one of the leading dollar spot fungicides in the market, controlling strains that iprodione and DMI fungicides have reduced activity on. It is an excellent rotational tool in anthracnose disease management. Compass offers a new mode of action in the combat against anthracnose either alone or in combination with other fungicides. • • With the active ingredient discovered at least 30 years later, Compass provides improved residual protection and activity over the other key turf contact fungicides in chlorothalonil and mancozeb. This makes Compass an ideal mixture candidate with systemic fungicides for extended, broad spectrum inside-out protection.

EARN YOUR WAY TO NZ 2018 WITH SYNGENTA’S TURF REWARDS AGCSA Gold Partner Syngenta, in conjunction with the AGCSA, in October launched an exciting new initiative that is giving course superintendents and turf managers an opportunity to earn their way to the inaugural Australasian Turfgrass Conference in Wellington, New Zealand (24-29 June, 2018). The Syngenta Turf Rewards programme gives turf managers the opportunity to accrue points when they buy certain Syngenta products. These points can then be used towards a range of industry discounts, including reduced delegate registration rates for the Australasian Turfgrass Conference, tickets to the conference President’s Dinner, AGCSA bookshop vouchers, annual AGCSA memberships and agronomic services such as water, soil and disease identification tests. The more points turf managers accrue, the bigger the rewards. “The AGCSA is delighted to team with long­ term industry supporter Syngenta to offer this joint initiative,” says AGCSA events and education manager Simone Staples. “This collaboration reinvests funds back into the industry and is designed to assist turf managers in a variety of different ways. Together, the AGCSA and Syngenta are, as always, committed to providing support services and professional development to all areas of the sport turf maintenance industry.” Adds Paul Jackson, Syngenta business manager turf and landscape, ANZ Lawn & Garden: “Our partnership with the AGCSA will assist turf managers in gaining relevant industry education and increase the use of scientific diagnostics within the professional turf management industry.” The Syngenta Turf Rewards programme runs until 31 March, 2018. Products can be purchased XPERT TECHNOLOGY CUTS A NEW COURSE fairways or greens are also recorded so the mower can move from one area to the next to mow automatically. A touch-screen terminal operates the whole system. This terminal displays information in 3D and is able to record hundreds of mowing routes and patterns. The system is easy to use and can be up and running within five minutes. The mower is also equipped with numerous safety features. The system checks itself and stops when an obstacle is detected in front or behind the mower. When the system stops, it informs the user via SMS. Xpert uses high precision GPS with centimetre accuracy to control the mower, allowing it to precisely repeat what was taught. Moreover, the GPS system can be used to create perfectly straight passes when recording a route. The machine will repeat these straight patterns time after time, ensuring a consistent and high quality of cut. Kits are currently available for Toro 3250 and 3400 greens mowers, as well as 5510, 5610 and 501 OH fairway mowers. For more information on the Xpert driverless mowing technology system, visit www.precisioncontrol.net.au. Victoria-based technology company Precision Control Australia has announced it is now the exclusive distributor for Precision Makers’ Xpert autonomous mowing system. The Dutch-built system is revolutionising the turf maintenance industry with a driverless kit now available for golf course mowers. Xpert technology enables mowing to be performed fully autonomously, freeing up staff to undertake other maintenance tasks. Xpert autonomous mowing kits are available in Australia for a range of Toro mowers Xpert uses one of two patented modes - either ‘Teach & Playback’ or ‘Dynamow’. To record a mowing route with ‘Teach & Playback’, operators simply step on the mower, press the ‘record’ button and mow as per normal. The system records every action - driving, steering, throttle operation and lowering and raising of the cutting units. Afterwards, the operator places the mower at the start of the route, presses ‘Play’ and the system will repeat this route, precisely and unattended. The ‘Dynamow’ function requires the course to be mapped once, marking boundaries, headlands and any obstacles present. The system then calculates the most efficient path based on the desired direction of cut. Transport routes between 68 AUSTRALIAN TURFGRASS MANAGEMENT 1 from a Syngenta agent or dealer.

MATCHPLAY RANGE EXPANDED The liquid nutritional range from AGCSA trade partner Living Turf has recently been strengthened by three new additions under the MATCHplay brand. MP Reinforce has been re-formulated to now contain monosilicic acid or MSA - the most plant- available form of Silica (Si) - to aid with cell wall strength, wear tolerance and improve essential nutrient uptake. MP Reinforce is also complemented by two new products - MP Enrich and MP Safe N. MP Enrich contains highly available dexlated chelates of iron and zinc that results in great colour and low burn potential. Dexlated chelates are known to be 100 per cent more efficient than inorganic iron salts to deliver long lasting colour. MP Safe N is a protein-based nitrogen source that is extremely safe to turf. It delivers efficient plant-recognisable nitrogen directly into the leaf tissue for optimised response. Both MP Enrich and MP Safe N contain VM3 technology that significantly enhances nutrient availability and contains beneficial bacteria, plant stimulants and trace minerals. For more information on the MATCHplay Superior Liquids range, contact your Living Turf specialist or visit www.livingturf.com.au.

Gisborne Golf Club (Victoria) and Gloucester Country Club (NSW) have each received the mowers, estimated at $18,000 each, which will give them a much-needed boost to maintaining their courses. For Gloucester Country Club, which has been in operation since the 1920s, the mower is a very timely addition. Superintendent Anthony Ross says the club’s goal is to promote golf in the area, however, the current equipment was in need of replacement and they had no means of funding it. “Our old mower had well over 4500 hours on it and was ready to breakdown any day,” says Ross. “We’re a club run by volunteers, I’m the only full time employee and we were in no position to buy new equipment. Winning this mower means we can present a great golf course for our members and the INDUSTRY APPOINTMENTS AGCSA Gold Partner Nuturf Australia announced in late September that it has secured the services of Robin Doodson as a Queensland territory manager. Doodson, currently course superintendent at Doha Golf Club in Qatar, will start his new role in early January 2018. Doodson is set to arrive at Nuturf with 16 years’ experience as a golf course superintendent, having managed both warm- and cool-season grasses. During his career to date Doodson has worked at Doha Golf Club and prior to that six years at Sanctuary Cove Golf and Country Club on the Gold Coast where he successfully guided the club through a $12 million redevelopment of the Palms Course. Says Nuturf business manager Peter Schumacher on the appointment: “I am excited about Robin’s decision to join the Nuturf business and know that he will strengthen our technical and service offering to the Queensland market. Robin’s experience in southeast Queensland golf is at the highest level possible and he will be a great addition to the Nuturf team and a great resource for our customers and all turf practitioners in Queensland. Robin has prepared golf courses for 22 PGA Tour events, is an AGCSA accredited superintendent, is a certified superintendent under the ISO 14001 International Standard for Environmental Management and is a past board member of the AGCSA and GCSAQ.” 70 AUSTRALIAN TURFGRASS MANAGEMENT I golfing community. It’s great to come in and know that the mower we now have is going to do an A1 job compared to our old mower.” Toro’s senior marketing manager for equipment, Elise Willemsen, says the company was overwhelmed by the positive response the Support and Grow Grants programme received and thanked all clubs that applied. “We are proud to assist through this programme and have no doubt this grant will benefit these two well-deserving clubs for many years to come,” says Willemsen. “The sheer number of applications received shows just how important programmes like this are to clubs all over Australia. We look forward to doing it all again next year!” JT TURF TAKES ON LASTEC, TRU-TURF DISTRIBUTIONS After a long association with Lastec and Tru- Turf, AGCSA Silver Partner Equipment Solutions announced in October that agreement had been reached with NSW-based JT Turf to transition the distribution of these products in Australia. “With a recent decision to align the Equipment Solutions business toward renovation equipment, we were looking for a professional business to take on the Lastec (national) and Tru-Turf (NSW) distributions,” says Peter Frewin, business manager for Globe Australia. “After some discussion, it was obvious that JT Turf was the perfect choice. “Equipment Solutions has had a long association with Lastec and Tru-Turf and as such we are delighted to have been able to facilitate a smooth transition of the respective distributions. Equipment Solutions’ recent acquisition oftheGraden Industries distribution nationally reinforces our commitment to the renovation machinery market.” JT Turf’s general manager for sales Justin Bradbury adds: “As part of our continued efforts to evolve into a sustainable partner for the turf industry, the additions of these great products and also the growing relationship with Globe Australia, are a fantastic way for JT Turf to ensure that we take all practicable steps towards that goal.” For more on the Lastec and Tru-Turf ranges available through JT Turf, contact Justin Bradbury on 0432 390 171 or visit www.jtturf.com.au TURF CULTURE RELEASES WALDO Turf Culture’s Waldo miticide (a.i.: 500g/L diafenthiuron) is now available to Australian turf managers for the control of couchgrass mite in turf.

Since our last article in the May-June 2017 edition, the SAGCSA has been reasonably quiet, although in August about 13 members attended the GCSAWA Margaret River Conference. The WA association puts on a great few days (except for the weather) and a big thanks goes to the GCSAWA organising committee for all their support in helping us get there and looking after us. Special mention also to the superintendents in and around Perth that welcomed us onto their courses for an inspection and a chat - Nick Price (The Cut), Adam Strachan (Secret Harbour), Simon Bourne (Cottesloe GC), Idris Evans (The Western Australian GC), Fraser Brown (Lake Karrinyup CC) and especially Darren Wilson (Wembley Park GC) for all his support. The SA crew all had a great time - the conference was first class with quality guest speakers and the following few days were equally fantastic visiting some of Perth’s finest courses. In September, the SAGCSA held a superintendents’ forum at our local Jacobsen dealer’s facility, Turf Equipment SA (Jordan Ormsby). After the forum some supers and managers gathered for some hospitality in the workshop. A huge thank you to Jordan, Zac, Mike and the Turf Equipment SA team. The Golf SA Awards night was held at the Playford Hotel in late October. The night was a great opportunity to recognise our high achievers. The SAGCSA handed out the Graduate of the Year Award to Matthew King (Flagstaff Hill GC) and Excellence in Turf Management Award to Nathan Bennett (Royal Adelaide GC). On behalf of the committee, congratulations to both Matthew and Nathan. The next SAGCSA event will be the rescheduled AGM, which was postponed back in July. This will be held at Royal Adelaide GC in early December. We have had some movement in the industry recently - Steve Newell heading home to Victoria GC from Kooyonga GC, with Richard James making the shift from The Grange GC to Kooyonga (he now gets to prepare Kooyonga for the 2018 Women’s Australian Open after having prepared The Grange for the same event in 2016!). After a short stint at Murray Downs in what was his first superintendent posting, Rowan Daymond returned to take the vacant seat at The Grange. Congratulations to all those guys. Finally, it was a few months back, but congratulations also to the AGCSA for putting on another great conference on the Sunshine Coast. The Future Turf Managers’ Initiative was given high praise by my assistant Simon Work who was fortunate enough to be selected for the programme. Wishing everyone the best with summer and Christmas coming up. BAZZ BRYANT PRESIDENT, SAGCSA Planning is well underway for 2018 STA Victoria events and we encourage you to contact us if you would like to see a particular subject addressed. We are planning a minimum of four events throughout 2018 with the main one being the annual Sports Turf Seminar, to be held on Wednesday 18 July. Stay tuned for more details. Following on the success of the Pitch Preparation Day at Flack Park in September, we are planning a similar event in September 2018 and will incorporate your feedback to make it an even better day. This is a ‘not-to-be-missed’ event open to not only beginners and volunteers but also experienced personnel engaged in the important seasonal task of building, preparing and maintaining a quality cricket pitch. We are excited to announce that we will soon be releasing a YouTube video produced from footage taken on the Pitch Preparation Day. The video will be a great training tool for school communities, country cricket clubs and councils. iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiniiiiiiiiiiii A reminder to all STA Victoria members, please communicate any workplace personnel changes, emails, addresses etc. We have had a number of magazine returns and appreciate advice of changes to enable all parties to update databases. Email changes to Jan Fenton vic@sportsturf.asn.au. We are looking to grow the STA Victoria Facebook page and encourage all members to participate by providing us with information and editorial. It is a great tool for sharing information. We also encourage the use of Twitter and Linkedln. As this edition of ATM was going to print we were looking forward to our final event of 2018 - the Toro Regional Sports Field & Ground Forum at Packer Park Pavilion, Carnegie. The STA Victoria committee thank you for your support and wish you a safe and happy holiday season. We look forward to providing information and support to the turf industry again in 2018. STA VIC COMMITTEE 72 AUSTRALIAN TURFGRASS MANAGEMENT 1 STANZ lllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll round much of New Zealand we are experiencing a pretty typical spring. The old adage of ‘four seasons in one day’ is never more true in terms of describing the weather this time of year. Up until early November, many of our premier sports fields resembled a paddock as opposed to a manicured sports surface. Now that the weather is starting to settle down and soil temperatures are creeping up, we are dealing with the usual flush of broadleaf weeds and awakening kikuyu. Winter rainfall has broken records along with the mean temperatures in many parts of New Zealand. This was the coldest winter since 2009 and in Christchurch rainfall to date has been 134 per cent above usual rainfall amounts (551 mm compared to 411 mm). Auckland experienced up to 902mm of rain (up to September) which sits significantly above the ‘normal’ rainfall for the same period - 753mm. Aside from weather issues, the New Zealand sports turf industry is gearing up for another big year of sport. At the moment we are enjoying co-hosting the 2017 Rugby League World Cup (RLWC) with games scheduled in many of our main centres. The recent Tonga v Samoa fixture at Hamilton’s FMG Stadium proved to be an amazing event that superseded the action on the field with the action and vibrancy in the stands! The RLWC has in many ways crept up on the New Zealand public and media, with relatively limited publicity or promotion prior to the games being hosted in this country. Later this summer, Hamilton will also host games in all three of the upcoming summer cricket series, with the West Indies, Pakistan and England all playing at the recently resurfaced Seddon Park Oval in the months between December and February. In addition, the Rugby 7s will also be staged at the FMG Stadium later in the season - Hamilton is the sporting destination of choice for 2017/18! As I write this update, the eyes of two nations were centred upon the turf at Westpac (Wellington) Stadium. The All Whites took on Peru in their 2018 FIFA World Cup qualifier showdown with the home side fighting out a 0-0 draw (they would go on to lose the return leg in Peru). The new surface at the stadium continues to perform well and receive positive feedback. How long will it be until we see a number of other stadiums in New Zealand going the way of hybrid or stabilised technology? We have been watching with interest regarding the many stadium venues now going this way in Australia. In terms of Kiwis on the international stage, it’s been very interesting to follow the progress of former Eden Park turf manager Mark Perham. Mark has been enlisted to act as a consultant for the ICC and oversee the installation of the portable cricket pitch and temporary outfield being installed at the London Olympic Stadium for the 2019 World FMG Stadium in Hamilton was one of a number of NZ venues that hosted games during the recent 2017 Rugby League World Cup Cup. The stadium could also be used in England’s revamped city-based Twenty20 competition, due to start in 2020. It’s great that our turfies are gaining international acknowledgement. It’s a busy summer ahead for our major and regional venues and turfies throughout New Zealand will be enjoying this all too brief period of growth and vigour prior to the onslaught of summer drought, heat and humidity that will doubtless ensue.

NOVEMBER-DECEMBER 2017 73 ASSOCIATION REPORTS STA WA llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll The regional forum is hosted in partnership with the various state STAs and when held in Perth on 8 November at the Larkhill Sports Complex in Port Kennedy, it was a brilliant success. We were very proud when the final registration tally for the day numbered 77 delegates, many of whom had travelled from far afield to participate. Above and below: Nearly 80 delegates, some travelling from up to eight hours away to attend, turned STA Western Australia held two events in out for the WA instalment of Toro’s regional sportsfield forum in early November recent months. The first was the annual STA WA Golf Challenge which was held on 11 October once again about the beautiful environs of the award-winning Hartfield Country Club (host superintendent Nick Kinley). The event this year was staged as an afternoon event, beginning with a light BBQ lunch thanks to sponsors State Wide Turf Services and Turfcare Australia, after which the players all enjoyed a relaxing and not-too- competitive nine holes of golf. Major sponsor for the day was Jacobsen/ McIntosh & Sons who very generously provided prizes for a number of novelty challenges for the players during the afternoon. Well-deserved thanks go to Mike Healy and Mike Foskett for their help making a very enjoyable afternoon; the STA WA looks forward to future events with Jacobsen. The next event was the much-anticipated Regional Sportsfield and Grounds Forum sponsored by Toro Australia. This event was designed and staged by Toro Australia and shares a very similar format with their much larger annually held national forum. For the past five years or more Toro has recognised the fantastic potential such events mean for not only their business but also the whole industry’s development, by reaching out in a cooperative and collaborative educational conversation with as many of their turf clients as possible. 74 AUSTRALIAN TURFGRASS MANAGEMENT ] 9 6 We had attendees come from Esperance (eight hours away), Albany (five), Busselton (four), Kulin (3.5) and Kojonup (three), as well as many other districts that were well over an hour’s drive away. Their effort was certainly well appreciated by our interstate guests and gave a clear indication of the value many regional grounds care teams place on training such as this. With such a good turnout we divvied up the crowd into three groups that rotated between a Toro machinery presentation with Scott Wallis, a Toro Irrigation presentation with Chris Williams and a Syngenta presentation with Paul Jackson. All the presenters did a truly brilliant job and I must say that I was greatly impressed with Scott Wallis, who did an outstanding job presenting a select range of Toro sports ground equipment. Throughout the presentations the hosts engaged common ground conversation with the delegates to relate on all aspects of their daily challenges managing their turf surfaces. Thumbs up also to the Toro Irrigation team on the day. Chris, Clint and Gareth spoiled us with an amazing demonstration of an absolute monster sprinkler that blasted a beautiful stream of water almost 50 meters across the synthetic courts! Paul Jackson and Matthew Holmes from Syngenta also put on a very informative presentation and delved into those questions that some seem always reticent to ask, such as practical tips and suggestions on making the most out of the growth regulator ‘Primo’. It was a beautiful spring day, although it continued to get quite warm, nudging 35 degrees as the afternoon wore on. When lunch finally came around (45 minutes late) and our BBQ specialist delivered up his man-sized portions of beef ribs and sausages, concerns about the weather were irrelevant. So good was the BBQ that when reading through the feedback forms later that evening, one happy delegate actually granted us an extra point with a score of a 6 out of 5 for the catering! Days like this cannot be put together without a fabulous support crew, such as from the City of Rockingham, Nathan Hayes and Paul Smith with their help with the venue and, last but not least, a big shout of thanks to my fellow STA WA committee colleagues Hugh Gardner, Greg Jackson and Shannon White, plus the inimitable Eva Ricci.

I’d like to thank the committee and VGCSA administration officer Mary Napier for their efforts and commitment in making 2017 a very successful year for the VGCSA. The schedule has been locked in for our 2018 meetings and we are pleased to announce the following dates and venues: • Education meeting (Monday 5 March): Frankston Golf Club and The National Golf Club - Long Island (superintendents Dean Hadfield and Simon Page). • Annual General Meeting (Wednesday 9 May): Victoria Golf Club (Steven Newell). • 2IC/3IC/Groundstaff meeting (Tuesday 5 June): Box Hill Golf Club (Josh Leyland). • Superintendent/2IC country meeting (Monday 30 July - Wednesday 1 August): Cobram Barooga GC (Matt McLeod). • Education meeting (Tuesday 11 September): Kew Golf Club (Cameron Hall). • VGCSA Open Golf Day (Monday 19 November): Spring Valley Golf Club (David Phillips). The support to the association from golf clubs in Victoria is second to none and we are very appreciative of this and thank all superintendents and their clubs for hosting these important meetings. Sponsorship and support from trade partners is again strong heading into 2018 and we thank the trade for their assistance towards the association’s productive operations. All ‘A Class’ members would have received their trade directory via email and we hope members continue to support our trade partners in 2018. In other news, trial work conducted over the winter period involving the control of Poa annua in couchgrass has been completed and results will be distributed to members in the New Year. A second trial concerning Poa annua control has already begun for the summer period across four sites in and around Melbourne. Hopefully we will see some promising results that members can utilise. Good luck to all those hosting tournaments across the country whether they are major or minor. Hope the summer provides some good growing weather and consistent rainfall. Merry Christmas and a safe New Year.

The National Red Imported Fire Ant Eradication Programme has been approved to deliver a 10-year plan to eradicate fire ants from Australia. The area of treatment is significantly expanded and between September 2017 and June 2018 there will be three rounds of treatment across the above- mentioned regions. Fire ant bait treatment involves the distribution of granulated bait over lawns, garden beds, paddocks and other open areas either by foot personnel, all-terrain vehicle or by helicopter. STA Queensland members who operate in these areas are encouraged to familiarise themselves with the programme as it is critical that parks, sports fields and other outdoor areas that receive fire ant bait treatment are not disturbed for 48 hours. This includes no irrigating, topdressing, applying insecticides or disturbing the ground where bait is laid. This allows worker ants to forage for bait and circulate it through the colony to the queen ant. Preventing the bait from taking effect may exacerbate a fire ant infestation, making it an offence under the Biosecurity Act 2014.

Improving durability of sports fields; We also held our annual renovation and construction field day in September hosted by Redlands Cricket. Redlands Cricket curator John McFarlane has been a regular recipient of the STA Queensland annual award for Curator of the Year and attendees were given guidance on the maintenance and different renovation practices to repair wickets after a game, oval renovation options and live machinery and product demonstrations. Dr Don Loch from the University of Queensland addressed the audience with updates on his research into couch mite while conducting a walk and talk of an area within the facility that has been affected. As part of the day, we were fortunate that Green Options were in the process of rebuilding an oval on Redlands College, which is next to Redlands Cricket. Here, the team gave an overview of the brief of the project as well as the construction practices they are incorporating into the rebuild. We are looking forward to finalising the categories and inviting members to nominate for the first annual STA Queensland Awards to be held on 4 May 2018. Members, nominees and associates will be celebrated at the Queensland Cricketers Club at The Gabba. Other meeting dates for the first half of 2018 include an education day on 13 March and STA Queensland AGM on 17 April.

He will be returning to his native New Zealand in January 78 AUSTRALIAN TURFGRASS MANAGEMENT There have been plenty of superintendent, assistant superintendent and sportsturf manager movements this spring, but none bigger than the two announcements made by Royal Sydney Golf Club in October. Late on Friday 6 October, it announced that Steve Marsden was finishing up as course superintendent and then just three weeks later it wasted little time to reveal the elevation of long-serving and highly-regarded assistant Adam Marchant to the superintendent role effective from late January 2018. Marsden’s announcement certainly took the industry by surprise, especially in light of the fact that Royal Sydney is about to embark on a major course redevelopment under the auspices of renowned golf course architect Gil Hanse. However, as he mentioned in the AGCSA’s enewsletter The Cut, Marsden commented the decision to leave the club and head back to his native New Zealand was more for family reasons than anything else. “It has been a very hard decision to come to, but it is one that we have based on lifestyle and trying to achieve a better work-life balance,” says Marsden. “I have had five great years at Royal Sydney and it has been a privilege to work alongside the excellent Turf Care crew and clubhouse staff who make this place so unique.” The news of Marchant’s posting was certainly a popular one and within a day of the AGCSA breaking the news to industry on its Facebook page, the post had more than 250 likes and over 100 comments! Marchant’s appointment came literally two months after he returned from a three month, club-approved stint working at Merion Golf Club in the US. Speaking in The Cut in late October, Marchant was excited about his new role: “I am very honoured to be given this opportunity. Royal Sydney has been a major part of my turf management career for more than 15 years and to follow in the footsteps of past superintendents and mentors John Odell and Steve Marsden is a huge privilege. “It is set to be a very exciting phase for the club in the coming years with Gil Hanse currently working on a masterplan which will be voted on by the members next year. I am very much looking forward to being involved in this and leading our talented and dedicated Turf Care team through what will hopefully be one of the most significant projects in the club’s history.” The refinements of Royal Sydney are far removed from where Marchant started his turf management career as a 17-year-old apprentice at Mudgee Soldiers Club, NSW in 1999. By sheer coincidence, that apprenticeship had become available because the previous apprentice had taken a role at Royal Sydney under then superintendent John Odell. Making contact with Odell, Marchant transferred his apprenticeship to Royal Sydney in his second year, starting in early 2001 just as the club was embarking on a major greens reconstruction project. After five years with the club, Marchant departed and spent a few years working for an irrigation company before returning to the club in 2008 as a senior greenkeeper. At the start of 2010 he was appointed Links foreman and following the departure of Odell and arrival of Marsden in late 2012, Marchant was appointed foreman of the club’s Northern Area (tennis, bowls and croquet) following the 2013 Emirates Australian Open. A restructure of the club’s senior staff in 2015 then saw Marchant appointed as one of two assistant course superintendents and he went on to play a major role in overseeing preparations for last year’s successful Emirates Australian Open. Marchant officially takes the superintendent reins on 23 January 2018. 4AGCSA PARTNER RECOGNITION PROGRAMME Support those organisations who support your association Thank you to all the partners who help the AGCSA provide members with the greatest programmes and services the industry has to offer.

Reaching new Bexley Golf Club superintendent Stephen Mallyon has a real taste for adventure outside of turf. heights B eyond the daily task of maintaining a golf course, staff and member expectations, there lies a deep passion for adventure and travel. This passion has led to many overseas expeditions to fuel and excite my inner adventurer. A couple of the most noticeable and exhilarating trips in recent times have included trekking to the southern base camp of Mt Everest and cycling up Mt Haleakala on the Hawaiian island of Maui. The expedition to Everest Base Camp, which sits at 17,598 feet (or 5364 metres), occurred last October and I completed it alongside my good mate of 25 years Gavin French. The return trip, once you are in Kathmandu, is only 15 days. While that might not sound like much, you are hiking between 7-9 hours per day on some extremely rough terrain and dealing with the effects of high altitude. Flying into Lukla airport (9334ft or 2845m), which is carved out of the side of a mountain deep in the Himalayas, definitely gets the adrenalin flowing straight away. A regular contender as the world’s most dangerous airport, as you fly in you can see the wreckages of numerous planes that didn’t quite make it strewn across the landscape. Once you step off the plane you meet your Sherpa and the trek begins immediately. The Sherpas make it look easy and it is amazing to see the weight they can carry (sometimes up to 100 kilograms) with a single hessian strap around their forehead. Throughout the trek you encounter some of the most photogenic sights on the planet. We also heard and witnessed about 10 avalanches, but thankfully none of them were close enough to worry our group. The sound they make is incredible as the echo rumbles around the mountainous landscape. 80 AUSTRALIAN TURFGRASS MANAGEMENT 19.6 Some of the wire cable bridges that you have to cross are like something out of an Indiana Jones movie! Some are over 400 feet high, spanning 150m in length across enormous gorges and just 1 m wide. And just to add to the experience, every now and then you’d come across a farmer walking his yaks! Needless to say, it was an amazing feeling to reach Everest Base Camp. I know it is only the starting point for the more serious mountaineers who go for the summit (maybe one day), but I cannot recommend it enough to people. It is very achievable and a big tick on the bucket list. ON YER BIKE! Cycling has been a growing passion of mine for the past 3-4 years and I need no excuse to head out for a ride when time allows. This past October I travelled to the island of Maui in Hawaii to celebrate my father- in-law’s 70th birthday and while there was able to indulge in another small adventure. Mt Haleakala, a massive shield volcano, sits on the east coast of Maui and is world famous for its ‘Cycle to the Sun’ event, one of the most difficult bike climbs in the world. The average gradient for the climb is 7-8 per cent with sections reaching 16 per cent. The total distance is only 58km to the summit (which sits at 10,023ft) but it is uphill all the way and not easy. I did the ride with my brother-in-law who is a much stronger rider than me. The day we chose to do the ride the weather was perfect with not a cloud in the sky. By the time the clouds did close in, we were already above them! There are tour operators that drive their customers to the top and they cycle down. We saw a lot of these groups who all yelled out as they sped past - ‘You’re crazy!’ Throughout the ride I casually consumed eight energy gels, four protein energy bars and around 10 litres of water. There was an immense feeling of pride reaching the summit and it was definitely a case of mind over matter to will my body to keep turning the pedals over to get to the top. It took us just over six hours to reach the summit and just over an hour to make the descent back to the car. The descent was certainly the fun part with perfectly cambered corners meaning you could get up some serious downhill speed. So where to next? Well, there’s still plenty of the world to see and together with my mate Gavin we are planning our next challenge which will be a hike to the summit of Mt Kilimanjaro in Tanzania some time in 2018. Let the adventures continue... 58 kilometres all uphill! Nice view though... Innovation Technology that Redefines 'Precision' for Turf Spraying System The all-new GeoLink™ is the industry's first turf-based precision spray system. It utilises cellular Real Time Kinematic (RTK) correction technology to provide sub-inch accuracy. This gives the operator the ability to map each spray area only once and spray it with precision year after year, saving time and resources, even for less experienced operators. The system also automatically turns individual nozzles on and off, which eliminates costly overlaps and missed strips. Reporting is simple with GeoLink™. Application rates, coverage maps, area and volume data are easily downloaded for analysis. The weatherproof touchscreen is rugged enough to withstand the most challenging conditions and makes application programming straightforward with just the touch of a button.
