Turf Grass First in the World to Receive Smart Approved WaterMark The Smart Approved WaterMark is a water conscious certification provided to products so that consumers can identify and access the most water efficient products available on the market. The Smart Approved WaterMark was established by the Water Services Association of Australia (WSAA) to provide an identifiable label for consumers so that they can make informed choices when choosing products, services and organisations that use water efficiently, reducing per capita water consumption and helping in the end goal of preserving such a precious resource. The Smart Approved WaterMark is aligned with the European Union under the Waterwise mark and in the USA under the WaterSense. a U.S. Environmental Protection Agency (EPA) program designed to encourage water efficiency in the United States, the aims of all three are to further support innovation in water conservation from Australia to Europe the USA and eventually across the globe. https://www.smartwatermark.org https://waterwise.org.uk https://www.epa.gov/watersense
TifTuf Hybrid Bermuda TifTuf Hybrid Bermuda has recently received certification and is the first and only turfgrass to ever receive the Smart Approved WaterMark in Australia and across the world. In the US, TifTuf will now automatically be approved for the ‘Water Sense’ program. This means TifTuf is the first turf grass not just in Australia, but throughout the world, to receive recognition to this level of water saving efficiency. In order to receive the Smart Approved WaterMark, there is a significant process that is undertaken and a strict set of criteria the product needs to adhere to. A technical expert panel independently assesses the applications of products and services undertaking the accreditation process. The panel of seven members and an independent chair who
represents international expertise in the field, examine all aspects of the product application and the associated evidence of water efficiency. TifTuf was entered into consideration for the Smart Approved WaterMark 4 years ago and now after many years of extensive independent scientific based testing and research for decreased water use and superior drought tolerance has now been formally recognised, certified and Smart WaterMark Approved.
Smart WaterMark Criteria The panel of experts meets to consider applications against the following criteria: Water saving That the primary purpose of the product or service is directly related to reducing actual water use and/or using water more efficiently, where there is a direct correlation between the use of the product and water savings. Fit for purpose That the appropriate use of the product or service is consistent with supplied instructions and other documentation. Meets regulations and standards That the product or service is of high quality and meets industry standards, and customer and community expectations, in relation to water use. Environmentally sustainable That the product or service, while satisfying the above three criteria, is environmentally sustainable, and despite claimed water savings will not adversely affect the environment in other areas. In Western Australia Water Corporation certify water efficient plants through the Waterwise program. The Waterwise program recognises the Smart Approved WaterMark which means TifTuf has also received the Waterwise Certification in WA.
Summary A trial was completed at STRI’s Redlands research facility on several cultivars of bermudagrass (couchgrasses). The objectives of this trial were as follows: 1. To determine the shade tolerance of TifTuf compared to Australian industry standard cultivars. 2. To determine the effect of irrigation on TifTuf compared to Australian industry standard cultivars. 3. To determine the wear tolerance of TifTuf compared to Australian industry standard cultivars. Shade was the first stress applied from May and continued throughout the whole trial period. Differential irrigation treatments were initiated in the middle of May, creating a second stress on the grass. In addition, wear was imposed in three periods: May to early July, late July to August, and October to November. These wear periods were interspersed with periods without wear to allow grass recovery. Data were analysed to determine the overall effect of cultivars (averaged over shade, irrigation, and wear), cultivar x shade interactions (averaged over irrigation and wear), cultivar x irrigation interactions (averaged over shade and wear) and cultivar x wear interactions (averaged over shade and irrigation). When averaged over shade, irrigation, and wear treatment, TifTuf were always among cultivars with the darkest green colour, best turf quality, densest ground cover and highest NDVI. During prolonged drought stress, TifTuf had much better performance (colour, quality, ground cover, NDVI, drought symptoms) than any other cultivar due to its superior drought tolerance. In terms of shade tolerance, TifTuf was able to maintain the best performance among all cultivars under both 60% shade and full sun. Shade treatment reduced the colour, quality, ground cover and NDVI of all cultivars when there was no drought stress. However, shade slowed down the water loss during drought stress and led to better performance of cultivars. Greater differences between TifTuf and other cultivars were observed under 60% shade during drought period due to the superior drought and shade tolerance of TifTuf. In terms of irrigation, the performance of TifTuf was better under standard irrigation (100% ET) compared to drought conditions. However, regardless of the irrigation rate, TifTuf produced statistically better turf colour, turf quality, ground cover, NDVI and less drought symptoms compared to other cultivars. In terms of wear, TifTuf was among the cultivars with better wear tolerance throughout the trial. Due to its superior drought tolerance, TifTuf was more tolerant to wear than any other cultivars when there was a prolonged drought stress.

Table 2: Mean ET rates (mm) of three couch cultivars over four repeat measurement cycles.
There were no significant differences in ET between the three cultivars in any of the four cycles. The mean ET values in each cycle were, in fact, remarkably close. It is clear that if there is any difference in drought tolerance between the three cultivars, it isn’t due to factors that affect ET, such as stomatal conductance, stomatal sensitivity or xylem conductivity. Towards the end of the month-long droughting from 11th March to 12th April, different replicates of Legend and Santa Ana lost green colour and showed visible signs of water stress, such as leaf rolling, leaf bronzing or bleaching (see photo below).

Because some replicates of Legend or Santa Ana experienced this stress a few days before other replicates, the ET rates between replicates would have varied somewhat towards the end of that measurement cycle; hence the larger LSD value. It was well worth continuing this stress, however, as it showed a difference in drought tolerance between TifTuf and the others. Although there was no difference in ET rate between the three cultivars, there was a visible difference in colour retention in prolonged drought. This points to TifTuf better exploiting a drought tolerance mechanism that the others did not - possibly an osmoregulative effect that maintained cell and tissue turgor, or possibly a protective effect from stress compounds, or possibly a continuation in plant integrity due to better carbohydrate reserves. At the conclusion of the drought cycles, one replicate of each cultivar was removed from the pot to observe root and rhizome production. In all three couch cultivars, root depth was to the full depth of the pot, and there was no observable difference in root density. Santa Ana and Wintergreen appeared devoid of rhizomes, Legend had some short but visible rhizomes, and TifTuf had a noticeably higher level of rhizome production.

Photo: comparison of rhizome development in lysimeter pots that were 6 months old.
Rhizome development can be slow in couchgrass, often taking into the second summer of establishment to fully develop. The early appearance of rhizomes in TifTuf is somewhat unexpected, as the triploid hybrids are not renowned for their rhizome production (McMaugh, pers. comm.). Conclusions * The drought damage to Wintergreen during the lead in to the trial clearly demonstrated that this cultivar had inferior drought resistance to the other three cultivars. * In four drying cycles, including a prolonged period without rainfall or irrigation, there was no significant difference in ET rate between the three couchgrass cultivars TifTuf, Santa Ana and Legend. * After prolonged drought, TifTuf retained green colour longer than the other cultivars. * TifTuf produced more rhizomes than the other cultivars, which might contribute to better drought tolerance.

The Australian sporting landscape is broad and as a nation we are competitive internationally in many sports. We succeed in competitive, combative team sports and many of these take place on grass playing surfaces. Think soccer, rugby league, rugby union and Aussie rules – all sports that have high expectations and requirements for grass playing surfaces due to the wear and tear they will incur during play.

Sports technology is continually evolving. There are advancements in training techniques and recovery, equipment improvements and better knowledge of what it takes to achieve elite performance. One factor that our athletes don’t have control over is the playing surface. This very important factor plays a significant part in providing the ideal platform for optimal performance and it’s not as simple as just having good grass anymore. If our athletes want to perform at their best on the international stage, they need to be
performing on the best playing surfaces available not just here in Australia, but anywhere. Lawn Solutions Australia has made it their mission to research and source the best new sports turf varieties available anywhere in the world, in order to provide our athletes with the foundation for success. TifTuf Hybrid Bermuda is a product of this research. TifTuf provides sports ground curators with a new turf variety that exceeds all other varieties currently existing within the sports field industry. TifTuf requires

significantly less inputs (fertiliser and water) and has a dense sward that enables it to handle high wear situations, whilst remaining soft and visually superior to other turf varieties. Prior to its release in Australia, TifTuf had been tested in: •
19 drought-stress trials
•
2 sports field wear tolerance trials, utilizing the Cady traffic simulator
•
4 irrigated, non-stress trials
These tests were conducted at The University of Georgia, The University of Florida, North Carolina State University, Oklahoma State University and Texas A&M University as part of the Federal Specialty Crop Research Initiative (SCRI) grant. TifTuf has been introduced into the Australian market through an exclusive arrangement with Lawn Solutions Australia. In just a short amount of time, it has sparked significant interest and been chosen as the new turf variety for many new sports grounds and sports field upgrades right across Australia. Jeff Gambin is a greenkeeper at Somerset College in Queensland. He was a golf course superintendent for 30 years, a property manager and an on-site training
officer for 10 years. During his time working on golf courses he had the experience of converting a ‘hinze’ variety of grass on fairways at Coolangatta/Tweed Heads Golf Course, managing couch variety Santa Ana at Gold Coast Burleigh Golf Course along with C2. He also worked with a couple of courses that used Winter Green couch. Mr Gambin recently had TifTuf installed at the college and said, “I would rate TifTuf above all the varieties I have worked with.” Turf producer Twin View Turf supplied TifTuf for the college and Mr Gambin complimented them on supplying and laying a beautiful, weed free turf. “After just experiencing our first winter, which had a couple of frosts, I was pleasantly surprised to see no patches of different colour or leaf texture over our two Rugby Fields”, he said Winter colour retention was also very good with just a couple of foliar applications of nitrogen/iron being required when we had a couple of Uni Games soccer matches.” “I was also pleasantly surprised how well the TifTuf handled the amount of wear from our school’s Rugby training sessions and games.” This is just one example of many that demonstrates the results that can be achieved by installing a superior turf variety such as TifTuf.

The First Solid Turfed TifTuf Sports Field in Australia The Dolphins required a full oval reconstruction and Lawn Solutions Australia member Twin View Turf (TVT) were initially contacted by ground manager Paynter Dixon to quote on the project. Twin View Turf had completed renovation works at the Redcliffe Leagues Club many times in the past and the club had requested them as a preferred supplier. This was a full oval reconstruction by Twin View Turf and was handed back to the club last week after its maintenance period. Why was TifTuf chosen? The ground was originally specified as Wintergreen Couch as the club wanted the same turf type as the Sunshine Coast Stadium. But after Twin View Turf had showed
them a sample of TifTuf and given them information about the significant advantages it had over Wintergreen, they started to reconsider. Malcom Caddies Ground Manager for Suncorp Stadium was also very interested in swapping over to TifTuf from Legend Couch at the time and this ultimately encouraged the Dolphins that TifTuf was the best option for them also.
Preparation • 2 total kill applications (Glyphosate Sprays) were completed in November to kill off all weeds and existing turf grasses that were on the field • Then the top 50mm of thatch and soil was removed to help prevent grow back of existing turf grasses
Twin View Turf were awarded the job on the 5th October and works commenced in mid-November to install the very first TifTuf sports field in Australia.
• Next step was to rotary hoe the surface to a fine tilth and the existing soil was laser graded
Trent Hobson was project manager for the field construction and provided the following information on the works completed:
• TVT then installed a drainage system than ran across the field at 3.5m spacing fence to fence

Maintenance in preparation for handover • Application of Pre-emergent herbicide
The Results The independent consultant, Paynter Dixon representative and the club were all extremely happy with the overall job and were very happy that they decided to go with TifTuf.
The new surface will be given a thorough workout starting today and tomorrow when the 2018 Rugby League Commonwealth Championships are held at the ground. Project Manager Trent Hobson is particularly excited saying he “Can’t wait to see this field in play after all the work that went into it. I think the dolphins and anyone else that plays here will be pumped with the quality of the field.” TifTuf has a very fine leaf blade with dense growth, making it ideal for a wide variety of applications. Its density enables it to handle high wear situations like backyards and sports fields whilst its fine blade ensures shade tolerance and a very soft leaf to walk on.

Tuf times for Primary Schools A NEW LOW MAINTENANCE PLAY SPACE FOR KIDS AT ST COLUMBKILLE’S CATHOLIC PRIMARY SCHOOL.
Principal Bradley Colquhoun and kids at St Columbkille’s Catholic Primary School
Countless studies have shown that well maintained lawn and green space areas have a positive benefit on public health outcomes. Turfgrasses play a critical role in the general health and welfare of our nation and as a result of increasing urbanisation, they are becoming more and more important for human health. Lawns, parks and open playgrounds provide areas of cool, clean and calm that are critical to improved health; they are oases that are somewhat freer of the stresses of daily life in an urban environment School playgrounds and sports fields are also a crucial part of a healthy and balanced education process and add to the overall appeal and practicality of a school. Many schools in built up environments find it hard to retain areas of open green space for their
students because of development pressures and the cost of maintaining and servicing these areas. One such school is St Columbkille’s primary school, situated 60km south of Sydney and just 5km north of the city of Wollongong, the school is a short walk from the shopping district of Corrimal, a popular suburb of the coastal city of Wollongong. The school is in a highly developed area so the available space for grounds is very limited. St Columbkille’s has one “paddock” of around 1400m2 that is used heavily by the students for sports classes, recess and lunch as well as before and after school care. The amount of little feet on this relatively small patch of grass is extreme to say the least. Current principal and sports fanatic Mr Bradley Colquhoun has made it a priority
16 / NE W P L AYG ROU N D FOR ST COLU M B K I LLE’S PS 14
to maintain this area in a usable state so the children at the school can play and learn in a safe and natural environment. “After several years of a sub-standard grass playground space, we have finally found a product that is deserving of our students” Said Mr Colquhoun. In late 2017, Mr Colquhoun contacted Lawn Solutions Australia to get advice on a revamp of this area to get it up to a standard that would be safe and enjoyable for the kids at the school to use. With the excess traffic and lack of a dedicated maintenance staff member, relying on volunteers for mowing and upkeep, the field had degraded over time and was becoming a hazard with grazed knees a common issue for the children. “We really needed a playground space that was safe, accessible and aesthetically pleasing for our students
be able to use and take great pride in” Mr Colquhoun commented. The school needed an attractive but hardy, low maintenance option for the paddock that would be able to handle the amount of foot traffic that it receives each day and not need constant attention to remain healthy and green. TifTuf Hybrid Bermuda grass was chosen because it answered the needs of the school and had been proven to sustain high traffic areas as well as being very drought tolerant. In December 2017, the school went ahead with the project, removing the existing turf and weeds, recommissioning the underground sprinkler system and Active Turf installing 1350m2 of premium TifTuf to cover the paddock and nearly a year later, the move has proven to be a winner. The
children returned to the 2018 school year to find a brilliant green field where there once was a worn and patchy cover and have been able to use the field without issue ever since. “The renovation of our primary grassed area using the TifTuf Hybrid Bermuda grass in consultation with Lawn Solutions Australia has provided our St Columbkille’s school, Corrimal and the wider community with a beautiful area and they just love playing on it” Mr Colquhoun iterated. The winter following the installation was a particularly cold and dry season, but the grass remained intact with no fertiliser and very minimal irrigation. Mr Colquhoun continued “This playground space is consistently used throughout the week for numerous activities. Throughout the autumn and winter months the cover of grass was exceptional and held up well throughout this
period. From a WHS perspective and overall functionality, the grass provided the students with a safe and reliable surface that was used several times per day, 5 days a week through Term 2 and 3.” In the term 3 holidays, Mr Colquhoun organised a renovation of the paddock, aerating, fertilising and topdressing the space to get it back to its original glory and the results were very pleasing. The inclusion of TifTuf, a grass bred especially for circumstances just like this, has made a small piece of real estate green, safe and user friendly again which has and will do a lot for the mental and physical health of the students at St Columbkilles for years to come.

Turf Certification WHAT IS IT AND WHY IS IT IMPORTANT? The International Turfgrass Genetic Assurance Program (ITGAP), was developed to ensure the years of research and development into a new turf variety wouldn’t be lost to contamination or cross pollination. ITGAP provides licences for turf producers to grow and sell these certified grasses and monitors their production systems and supply of planting material. This ensures the traits for selection are not lost. In Australia, the ITGAP Program is implemented through AusGAP, which is the only registered agent for ITGAP outside of the United States in the world, run by Program Manager Nick Dorney.
What is the distinction between specifying and installing certified turf, versus uncertified turf? And what is certification, anyway? Terry Hollifield is the Executive Director of the Georgia Crop Improvement Association, the certifying agency that inspects sod farms and certifies turf in the US state of Georgia. Georgia Crop Improvement is one of 44 such agencies in the United States. “If a landscaper, or an architect, knows that they have a situation that needs a certain variety with particular characteristics like shade tolerance or winter tolerance in the transition zone, so there’s no winter kill, or if they are looking for a grass that’s low
30 / TH E I MP O R TA N C E OF T U R F C E R T I F I C ATION 28
maintenance, the only assurance they have of getting that variety is through certification,” Hollifield says. “State and federal laws don’t apply to vegetative turfgrasses, the only standard is to require certification.” The process of certification begins with the turf developer or breeder. “It doesn’t matter if it’s a university variety or a private variety, the inventor of a new variety must complete an application for approval of the variety to be certified. The application includes information such as breeding history, (Selected or bred? produced through asexual reproduction? naturally occurring? or irradiated?) then

they complete a section that talks about leaf colour, leaf shape, stolon colour, length of internodes, all those characteristics that determine a variety,” Hollifield says. Claims such as cold tolerance, shade tolerance, or drought resistance must also be substantiated. “If you make a claim about the variety, this claim must be substantiated with reputable data. Say a breeder claims the grass has a light green stolon, that doesn’t mean anything, it must be referenced on the Munzel colour chart, or another known colour chart used for identification. It’s got to be good science. Any claim that is made, whether it’s a claim that I use as I make a field inspection, or a performance claim, (such as cold tolerance or drought tolerance), data must be provided.” he says. Once a variety is approved for inclusion in the certification program, it will be licensed to turf producers who plant it on land that has been sterilised and known to be free of pests, weeds and foreign turf varieties. As the crop of turf grows in, it is subject to a minimum of four inspections per year by the growers and two by an ITGAP representative. Specially trained third-party inspectors who are not employed by the turf farms themselves walk every inch of a turf farm looking for weeds and off-type grasses. If weeds or off-type grasses are found in a field, that field may be quarantined, meaning no turf can be harvested from that field until the weed or off-type is removed and the field has been re-inspected for varietal purity. “Sometimes I feel like I’ve walked from Darwin to Adelaide and back five times in my career looking for that needle in a haystack,” says Nick Dorney. Dorney, who has been responsible for the implementation and running of the AusGAP program in Australia, inspects every licensed AusGAP farm for weeds and off-type grasses. “With some varieties, you’re looking for a needle in a haystack, that clump of grass that may be no bigger than a thimble.”

Water-less grass NEW RESEARCH IS CONFIRMING THAT TIFTUF TRULY LIVES UP TO ITS NAME
Turf trials by Melbourne Polytechnic Turf research in recent times has focused on finding new varieties of grass that have superior characteristics beneficial to the changing environment. At the top of this list of characteristics is the need for turf varieties that use less water, with a greater drought tolerance. TifTuf is a Hybrid- Bermuda (couch) grass that has been bred to stand up to drought conditions, save water and has become the new benchmark when it comes to measuring the drought tolerance of turf. Melbourne Polytechnic recently undertook a trial of four different couch grasses and measured how they responded to drought like conditions. The couch grasses included in this trial were Legend, Santa Ana, TifTuf and Wintergreen. The three

Conclusion: • After prolonged drought, TifTuf retained green colour longer than the other grasses. • TifTuf produced more rhizomes than the other cultivars, which might contribute to better drought tolerance.

This points to TifTuf better exploiting a drought tolerance mechanism that the others don’t have.TifTuf also had a noticeably higher level of rhizome production. The image to the left is a close up of the rhizome growth, another sign of a highly drought tolerant grass. For a lawn that requires less water and can stand up to drought conditions, you can’t go past TifTuf.
