Summer has brought with it some pretty extreme weather conditions which have kept everyone in the industry on their toes. While Queensland looks to be verging on another drought, Victoria experienced its hottest December on record while in the same month Melbourne was awash after a one-in-a-hundred-year storm wrecked havoc across the city. Mother Nature has a lot of answer for. Feedback from the last edition (Vol 5.6: Warringah Golf Club: An Accident Waiting to Happen) has been tremendous and I can safely assume that it has made for much debate in sheds and clubhouses across the land. No doubt opinions as to the incident itself and the consequences for both superintendent and club are wide and varied, but in the end the lessons need to be learned from both sides. Lets hope we never see another cover like we did in Vol. 5.6. With 2004 now in full swing, this edition kicks off the year looking at how superintendents can better manage their business and human resources. Planning and strategy guru Terri Clementson starts proceedings with a look into planning for the year ahead and methods superintendents can employ to effectively do so. In response to issues raised during the AGCSA's AGM at last year's conference in Adelaide, the Association's legal eagle Lorna Gelbert tackles the thorny quagmire that is employment contracts. We also revisit the topic of machinery washdown and waste disposal facilities, while mechanic Mark Browne swaps a spanner for a pen to regale us with the ins and outs of purchasing second-hand machinery. Now, how about this edition's cover model! A looker or what?! ATM has never had such a stunning supermodel on its primary page! Owner of the svelte physique is none other than Patterson River Country Club superintendent Michael Riordan who for the past four years has had the sound of excavators, diggers and chainsaws ringing in his ears. Riordan has overseen what has been a mammoth project at the Melbourne bayside club and in this edition we look at his exploits and achievements. The article serves as a lead-in to a general wrap of other projects and construction work that are currently on the go at various clubs around Victoria and Tasmania. This is the first of an ongoing feature which will tour each state. So supers, get those makeovers on the go. You never know who might be the face of Vol 6.2! And finally, while we're on the topic of new features, we also welcome back AGCSA Technical Officer Andrew Peart's regular Tech Talk column. Peart, who fancies himself as a bit of a wordsmith, presents an article on vegetative planting. So, plenty to delve into. See you in the autumn. Cheers.

Over the past five years the magazine has developed into what is the benchmark publication for the turf industry by being able to deliver to readers the latest information and research articles for dissemination. The AGCSA is proud of its magazine and I am sure that this sixth year will see it continue to grow and develop even further. The end of 2003 saw three great golf tournaments telecast around the country, and congratulations must go to those facilities in the very professional way in which their courses were presented. It is a credit to all those involved and I am sure that a great deal of satisfaction comes from having your facility presented to a huge tele-vision audience and to the other forms of media. The Australian Open in particular marked the beginning of a special arrangement between the AGCSA and the Australian Golf Union. AGCSATech manager John Neylan played an integral role in the course preparation committee as an agronomic consultant before and during the tournament. The arrangement was a huge success and John will again be involved when the Centenary Australian Open will be played out at The Australian Golf Club in November. Also, a big thank-you goes to all those people who took the opportunity to get up close and personal at the Open by taking part in the Course Quality Officials program. Ninety-one CQOs battled the mammoth Moonah Links layout which was in top notch condition under the auspices of superintendent Leigh Yanner. The New Year will herald the new-look AGCSA website and the beginning of a regular electronic newsletter to all members who have furnished their respective details into the AGCSA database. Preparations for the 20th Australian Turfgrass Conference in Melbourne continue to progress well. Tradeshow booth sales are on target while an elite line-up of international guest speakers has already been confirmed. The autumn roving workshop series is just around the corner, with the first due to be held in Melbourne on 22 April. Adelaide, Perth, Sydney, and Brisbane follow in that order. Check your AGCSA 2004 year planner for exact dates. The last edition of Australian Turfgrass Management magazine (Vol 5.6 - Warringah Golf Club) has certainly created a lot of bar chat in many golf clubs around the country and the feedback has all been of a very positive nature. I am sure that quite a few golf club boards and committees are now taking some form of measures to ensure that compliance is the word of choice when it comes to all things of an environmental nature as well as issues involving occupational and workplace health and safety. The AGCSA Board has also had the opportunity to meet over the past two months to review the Association's strategic plan and also receive updates from the turf education committee. The AGCSA is also looking into establishing an environmental working group in light of recent events, so the next few months will keep everyone on their toes. I hope that the New Year brings all our readers the best of health and all that they wish...especially rain to all those drought effected throughout Australia. Enjoy the magazine. ± Mark K Couchman President, AGCSA Golf Course Manager, Cromer Golf Club will nun out of Booths before youinuikout of products to selll When the industry gathers in June of this year we hope you're not one of the companies disappointed about not being a part of the 20th Australian Turfgrass Trade Exhibition.

Starting '04 on the Front Foot Managing Your Business and Human Resources Human and business resource management expert Terri Clementson looks ahead to 2004 and gives superintendents some tools to plan and manage the challenging year ahead. Most superintendents I've spoken with already in 2004 are working hard to make it through a tough summer. Water resource management problems are creating a more complex backdrop than usual in the busiest time of the year. Many are also now thinking ahead and trying to anticipate the work associated if it's a dry winter. There is little time to think long-term right now. Most superintendents say that planning, research, budget forecasting and any kind of long-term development of the course or their team realistically has to wait for space and time in winter. They also acknowledge that they need to do more of this and never seem to get that time. It may seem unrealistic, but now is the time to be thinking, researching and planning the year ahead. Seasoned superintendents know that, even though the timing couldn't be worse, those around them think "new year, new plans". This article gives you a simple template to ensure you are ready with clear thinking; information and a clear direction to meet the New Year zeal of course committees, treasurers, members and staff who see it as the start of their new year, not the middle and peak of yours. A Visual Plan - Your Best Defence The most common tension, frustration and time consuming distraction for a superintendent can be managing the input and influence of committees and members who feel they are managing the course, instead of overseeing the quality of your management of it. Many committee members will assume control if you don't clearly take it. A simple visual plan for all to see says "We've got this under control". It also offers a clear signoff tool that may help curb a committee's desire to change priority or direct resources to what are, in the bigger scene of things, relatively minor matters that take attention and resources away from managing significant risks. A simple visual tool can be a great anchor-point, not only for committees but also for your team. A Simple Template Planning doesn't need to involve lots of time and long wordy documents that sit on shelves gathering dust. The best plan is visual, simple, clear and can be viewed at-a-glance. Planning really just involves using a structured approach to put a few pegs in the sand about changes you'll be making this year and giving some clear thought to the risks you need to manage. The easiest way to organise your thoughts is to work methodically through each area of business management responsibility associated with your role. These include: Ł The club and course's current direction and focus; Ł Operations management; Ł Finance; Ł Marketing; Ł Human Resources; You might also consider the drivers you have to work with - external influences and you and your team's readiness for change. Managing these last three factors will determine your capacity to execute the plans you've made. In the box opposite is a simple template. It offers you prompts to consider. Work your way through each heading checking, and ideally jotting down a few ideas about, how you plan to respond to or lead changes in each area. Control, Modelling Leadership and Managing Others' 'Buy-In' The best results are often achieved when this type of analysis is done quickly and then thrown over to the team behind you to add their ideas and give some input before it looks like it's cast in stone. It would be nice to do lots of analysis -gather data about weather trends; monitor and track player traffic and behaviour for impact on surface and player satisfaction etc - but quite frankly, club environments and money for research probably only warrants that level of detail every five years. Documenting your planning on butcher's paper using the template as a prompt means it is a living document. You can take it into committee meetings to discuss your plans in a practical and efficient matter then take it back and put it up in the work area, as a guide. There really isn't much benefit in throwing resources at this and getting too glamorous with PowerPoint or a detailed report. It may give some comfort that it looks good, but using the time to develop neat content will pay a better dividend for your effort. The idea of getting plans down in January in a form you can use to brief others at the start of their year is designed to demonstrate; Ł That you have already done some clear, solid thinking and planning - to lead those who are helping drive the course's development (secretary manager, committee and staff); 18 A T M TERRI CLEMENTSON That you are actively leading the area, managing your business not just working in it; That the planning process is dynamic and collaborative. Edit the model as you discuss it; add ideas; expand it if necessary; and That once agreed, the plan becomes the roadmap for the year and remains in use, displayed and referred to regularly. Only extraordinary unforseen issues should call for action outside this plan. competes for limited time will mean you never make time to think and plan. Failure to plan gives others an 'in' to think they need to do it. Using a streamlined approach; racing through it with a few hours thinking and turning it into a practical map for the year can set a fabulous tone and inspiration for the year ahead. If you wait till winter you've missed the New Year wave and sure enough, someone else will be trying to push you to implement the plans they had in their head in January for your course! Do it now! Start the year on the front foot. Terri Clementson is a consultant with McArthur Management Services in Melbourne, a Turn Plans into Reality The final step is to take the plan and break it into sub-steps for the seasons. Take each area, jot the objective and then outline the steps to achieve the objective in each sector for each season. For example, there are multiple issues to consider in Operations Management. One may be the need to work on looking at sustainable grass use on your course. The task involves multiple steps: researching alternatives; costing alternatives; doing a few trial plots in optimal weather; reporting on them over changing seasons; getting member feedback on the trial holes then putting the decision to the committee for implementation at the right time to enable optimal yield. Plotting what you will do towards this objective each season gives those involved a sense that objectives need to be broken down into action steps and the timing of their execution, and associated expenditure, planned.

Every employee has an employment contract whether or not it is in writing. An oral contract will come into existence when a prospective employee applies for a position in answer to an employer's advertisement in a newspaper, an interview takes place, the employer offers the job to the candidate and the candidate accepts the offer. The offer and acceptance are sometimes in writing, sometimes verbal. The new employee then starts work and is paid by the employer and both parties are then performing the contract. This oral contract represents an agreement reached between the employer and the employee. Once the contract is made, one party cannot change the terms and conditions of that contract without the consent of the other party. For example, the employee cannot insist on working different hours; the employer cannot pay the employee less than was agreed or demote the employee. If there is no written contract the terms and conditions of the oral contract will be determined in a number of different ways, for example; Ł As set out in any letter of offer (eg: the position offered, the wage or salary payable, allowances such as for a motor vehicle, the specific duties of the position); Ł An award or industrial agreement (eg: minimum pay rates, leave entitlements, overtime and penalty rates, minimum notice periods on termination, redundancy); Ł By law (eg: long service leave entitlements, minimum terms in the Workplace Relations Act 1996 (for Victorian employees)); Ł Conduct and practice. That is how the contract of employment has been performed during an existing employment relationship (eg: when leave is taken, the policies and procedures of the employer, payment of redundancy pay at certain rates by the employer to previously retrenched employees); Ł Terms and duties that are implied by law. WRITTEN EMPLOYMENT CONTRACTS Written employment contracts are far more prevalent than in past years. Many employers now have standard employment agreements and position descriptions or duty statements for their staff and now require an employment contract to be signed. If an employee is covered by a State or Federal Award, an employment contract will not override that award unless it is: Ł A Certified Agreement (CA), which is an agreement made between the employer, employees and, usually, the employee's union. It is certified by the Australian Industrial Relations Commission (AIRC); or Ł An Australian Workplace Agreement (AWA) which is an individual agreement negotiated between the employer and the employee and registered with the AIRC. Both Certified CAs and AWAs are used to build flexibility into the award that governs the working relationship. The AIRC measures these agreements against an applicable award to ensure the employee suffers no overall disadvantage under the terms of the employment contract. Employment contracts that are not CAs or AWAs are referred to as common law contracts. If an employee is covered by an award and has also signed a common law employment contract, the employee will have the best of both worlds. If the award condition is better than the contract, the award condition will prevail. If the contract condition is better than the award, the contract condition will prevail. NEW EMPLOYEES If it is a condition of the offer of employment in a new position that the employee will sign an employment contract then the employee will have no grounds to refuse to sign a reasonable contract. Before commencing work however, prospective employees must make sure they obtain a copy of the contract, read it very carefully and, preferably, have a lawyer advise them on it. There will almost certainly be a number of clauses in it that could have a significant effect on the way in which the employment relationship will continue. As these matters may not be covered by the award, they will apply if the contract is signed. The employee must also ensure that all relevant matters are included in the contract. The advantage of having a well written employment contract is that the terms and conditions of the employment will be clear and will be binding on all the parties. It is often the case, however, that the terms are not expressed clearly and causes ambiguity that creates conflict. If you are unclear about the meaning of any clause in a contract, ask for clarification and have the wording changed so that it is clear. ho A T M m LK/ The Jacobsen E-Walk and E-Plex electric, precision-cut greens mowers.

It creates legally enforceable obligations on both parties. If an employment relationship is already being performed under an oral contract of employment, the employer cannot force an employee to sign an employment contract -particularly where the terms and conditions of employment may be different to and less favourable than the oral contract already in existence. If an employee signs that contract, they will be bound by its terms. If the terms of the written contract are different to the previous oral employment contract, the signing of the contract will be evidence of an agreement to vary the previous oral contract. For example, most employment contracts have termination clauses in them that give either party the right to terminate the employment on giving a specified period of notice (eg: one month). The Workplace Relations Act and most awards provide for minimum notice periods of between one and five weeks depending on the length of service of the employee. However, if an employee has been employed for a long period, say 10 years or more, the common law requires an employer to pay "reasonable notice" which would be much more than the minimum notice. A long term employee may be entitled to three, six or even up to 12 months' pay in lieu of notice in certain circumstances. If that employee signs a contract agreeing to accept only one months' notice, he or she may be limiting their rights at common law. Consequently, before signing any employment contract, existing employees must obtain independent advice to ensure they are not unwittingly signing away entitlements. for effective, efficient, controlled and safe spraying - even on windy days! 7he new Spraydome 5000 with its ground-hugging, all-round protective skirt means that wind drift is virtually eliminated.

Employees must carry out their duties to the best of their ability. The duty to obey the employer's lawful commands. An employee is required to carry out all reasonable commands of the employer. What is reasonable will vary according to the nature and duties of the employment but, generally speaking, commands that relate to safety in the workplace, standard of dress, observing the employer's practices, procedures and policies will be considered reasonable. The duty to provide faithful service. An employee must not behave in a way that will harm the employer or its business. An example of this would be an employee who sets himself or herself up in competition. An employee who leaves the employment and then sets up in competition will not necessarily be in breach unless there are restraint provisions in the employment contract that would prevent him or her from doing so.

A T M 13| How Green is Your Golf Course? Managing Your Business and Human Resources An example of a typical water recycling system In light of the recent Warringah Golf Club verdict, ATM revisits the topics of machinery washdown facilties and the disposal of waste water, which should prove handy revision for most. With the continuance of drought and water restrictions, global warming, environmental degradation and a host of other headline issues related to water use, conservation and quality, public awareness of water issues has soared. Regulation and enforcement has increased in a commensurate manner to the point where all facilities generating washdown water are now required to have a treatment or recycling system in place and face hefty fines if they fail to do so. Golf courses invariably face the need to wash turf machinery which generate contaminated waste water requiring treatment prior to discharge to the environment or council sewer. Where sewer is available golf courses generally are required to discharge waste water to sewer after it has been treated to a level that complies with the council sewer admission standards which form part of the Trade Waste Agreement issued by the council. If sewer is not available on site then discharge to the environment is governed by the EPA whose admission standards are considerably more stringent than sewer as the water passes directly to the environment without further treatment. While many golf courses have a designated storage area for pesticides, only a few have dedicated washdown bays and even fewer treat the wastewater generated. The traditional washdown facility on many golf courses in Australia is at best a concrete washdown pad and pesticide mixing area, with a drain that discharges into a soakage pit, stormwater drain or directly to surface waters. Allowing contaminated wastewater from washdown bays to drain directly into stormwater or surface waters would be an offence and could lead to fines and/or notices being imposed on operators. Local councils regulate pollution of waters provisions applicable to golf courses under the POEO Act, unless that council is the golf course operator/owner (in which case the EPA becomes the regulator). Washdown facilities also have to cope with clippings, oils and other contaminants. Of particular concern is the spillage of pesticide concentrates that could enter local waterways. Such an occurrence is not only environmentally unacceptable, but will also reinforce any community perceptions of golf courses being environmental polluters. Washdown facilities are recommended to be separate from spray tank filling facilities to reduce the likelihood of a spill from mixing pesticides or filling or cleaning spray tanks and equipment lines. If such activities were conducted on the machinery washdown facility loading, it could lead to pesticide contamination of the greater volume of washdown water and render that waste water to be hazardous waste. Factors to consider when designing such a machinery washdown facility are listed below. Trade waste may be accepted into the sewerage system if it complies with council's or the water authority's requirements and only under the terms and conditions of a council trade waste permit/agreement. This permit controls the quality and quantity of trade waste, allowing it to be transported without having any adverse effects on the sewerage system, wastewater purification process, the safety of workers or the environment. Wherever trade waste is generated, the property owner must apply to council or water authority on a prescribed form for a permit/agreement that allows the discharge of trade waste. A trade waste permit/agreement will have standard conditions as well as specific requirements for the particular demands of the activity. The agreement is negotiated on a case-by-case basis. If a trade waste discharge is to be considered, it is important that the waste stream is analysed for the various contaminants that can be in the waste stream. Each council or water authority is responsible for setting its own limits and needs to be consulted locally for requirements. A general set up of washdown facilities at some courses around Australia are as follows; Ł A concrete pad that slopes inwards towards a central pit. The design is such that all washdown water is contained and that no stormwater can enter the facility Ł The water enters a pit in which there is a mesh screen to catch grass clippings. An appropriate lifting device (e.g. a gantry lift) is often needed to remove the grass screen as it can become very heavy; Ł Water passes through the grass screen and then through a sand/silt trap to trap all soil particles; Ł Water is then pumped through a triple interceptor pit to separate the oil/grease from the water; Ł The clean water is then discharged to the sewer or other approved location. It may be possible to filter the water through a constructed wetland or to irrigate adjacent turf/garden areas. A TM In terms of the size of the washdown facility, the minimum area would need to be adequate for taking the largest machine. At golf courses with larger numbers of machines it will be necessary to set up the facility so that multiple machines can be washed at the same time. This is important in ensuring that staff are not waiting unnecessarily until they can access the washdown facility. Generally speaking there are two types of installations available for golf courses: standard treatment systems and recycling systems which are applicable to golf courses. STANDARD SYSTEMS (ROOFED AREA) This would typically employ an oil/water separator system which will treat water captured from workshop and machinery washdown and enable the water to be discharged to sewer or, with modification, to the environment and will meet all council or EPA requirements. A pump supplied with the system is utilised to draw the water from a holding tank and pump into a coalescing type separator which will remove much of the solids and over 99 per cent of any oil which is ducted to a waste oil drum. It is simple to install, operate and maintain and requires an in-ground holding tank to be installed for dirty water storage. The separator discharges directly to sewer by gravity or alternately the water can be pumped for irrigation or dust suppression. The discharge from this system is not suitable for recycling. Equipment cost for these systems, excluding site work, holding tank or installation, can be anywhere between $5000 and $7000. RECYCLING SYSTEMS (ROOFED AREA) Recycling systems treat waste water and produce recycled water that is suitable for reuse for wash down. Depending on the facility and how much water is lost to evaporation or overspray, the system will recycle approximately 80 per cent of all water used, dramatically cutting water costs and satisfying water restriction rules. The water is injected with a flocculent to drop oil and solids out and is subsequently filtered and chlorine dosed to ensure that it is pressure washer friendly, odour free and meets OH&S requirements. The equipment cost for these systems, excluding site work, holding tanks or installation can be anywhere between $15,000 for a small system through to $30,000 for a large system, a General considerations for a machinery washdown facility. Ł The likely composition and volume of the wastewater; Ł Characteristics of the local environment (e.g. natural surface and ground waters, endangered species and their habitats, remnant vegetation, adjacent land uses), that may be at risk from any releases or will receive any current or proposed stormwater or other discharges that have been appropriately treated; Ł Legislative requirements including preventing water pollution (POEO Act); Ł Installation and maintenance costs; Ł Sufficient containment area/holding pit for washdown water; Ł Collection and storage facility for washdown water for current or future use; Ł Screen and settling pit fitted to trap solids such as soil and grass clippings, Ł Interceptor pits to remove grease and oil; Ł Facility to treat wastewater to reduce biological oxygen demand; Ł Facility to reuse wastewater on site for irrigating turf; Ł Water quality that meets requirements for approval of local sewage service provider for disposal of treated wastewater to sewer. ^ANTONIO CARPARO Can you see where the Antonio Carraro tractor has been on this golf course?

A T M 13| Buying Second-Hand Machinery - Do The Homework Managing Your Business and Human Resources < / / Victorian Turf Equipment Technicians' Association vice president Mark Browne looks at the burgeoning second-hand machinery market and provides a useful checklist that mechanics and superintendents should consider when buying used equipment for their golf course. When considering the purchase of second-hand machinery for golf courses, a number of factors must be looked at and put into the equation when weighing up whether to buy used or buy new. Of course, the purchase price of a second-hand machine can be considerably less than buying new. This would be a main factor to some clubs, and more so for smaller clubs and country clubs on tighter budgets where the purchase of a new machine could be out of the question. Price alone, of course, is not the only consideration when buying second-hand and many other factors come into play that must be taken into account. With an emerging second-hand market and turf equipment magazines such as The Ground-sman advertising an array of turf equipment, the second-hand market is large, which augurs well for those superintendents and turf managers intending on buying second-hand. By browsing through these types of publications buyers can get a good idea about the market value of a particular model of machine they require. In my experience at the Eastern Golf Club in Melbourne, most of our main equipment is purchased new, such as fairway mowers, greens mowers, outer surrounds mowers, commercial deck rotary mowers and turf trucksters. We also have the ability to have a machinery replacement programme whereby equipment is purchased when it has reached a certain age. This is fitted into the overall budget of machinery and doesn't come unexpected when $90-100,000 has to be provided for a new fairway mower. The purchase of second-hand machinery for probably most of the metropolitan and country clubs comes into importance when buying equipment that would be used on a seasonal basis and as such tends to last many more years. Therefore items such as topdressers, sod cutters, walk-behind cylinder mowers and scarifiers, tractors, vertidrains and aerators could be considered as items to look for second-hand. Of course there are many more things to look out for when buying second-hand. We must remember that we are purchasing something that may have done anything from 500-5000 hours work and the risks of blowing the budget on a machine that at first looked a good buy on price could make the machine not worth purchasing, as the cost involved on ancillary repairs and parts could make the purchase not viable. Warranties are considerably less on used machinery as where a new machine would come with a 12 month to maybe two year warranty, used machinery may only come with a three month warranty. The golf course turf mechanic and course superintendent should liase with each other and inspect the item of machinery being considered, as two heads generally are better than one when looking over a piece of second-hand machinery. Whereas the mechanic may look at the condition of the engine and hydraulics as a major factor, the superintendent may consider the type of cutting unit to be of more importance. Below is a checklist of some points that are important to consider when purchasing second-hand equipment. Another worthwhile point would be to speak to the mechanic and superintendent where the machine originally came from. Most reputable dealers should have no hesitation in giving that information to a potential purchaser. Dealers usually have the first choice of second-hand machinery when a buyer trades up and therefore have the first call on whether a trade-in is worthwhile to put on their second hand lot. The main manufacturers and their dealers are a very useful source for finding good second-hand machines. As with the purchase of a new car, large dollar savings can be made on machines that have been used for demonstrations at trade fairs etc. and would still normally come with a full manufacturer's warranty and with only small hours on the clock. Some dealers also offer free delivery to capital cities in Australia for their second-hand machines. All of the well-known turf equipment manufacturers such as Jacobsen, John Deere and Toro make very good equipment and debate arises on the issues of ease of serviceability, operator comfort, spare parts availability, cutting units and overall quality of lie A T M cut. Most of the larger dealers also offer finance and leasing deals on their equipment. So in summary, when looking for used equipment, as in most purchases, the buyer needs to do their homework in regards to studying the second-hand market. Looking through magazines and newspapers, we can find an array of second hand machinery. The Victorian Turf Equipment Technicians' Association magazine also offers members and their golf courses the ability to advertise second hand machinery and these can be a good source too. And don't forget word of mouth through technicians' meetings and golf course superintendents' meetings as you never know what might be hidden in the old shed behind the ninth green at someone's golf club. ACKNOWLEDGEMENTS Mark Browne is mechanic at the Eastern Golf Club in Doncaster, Victoria and is vice president of the Victorian Turf Equipment Technicians' Association A SECOND-HAND CHECKLIST Ł Look at the overall visual appearance of the machine (eg: dents, scratches on the bodywork, tyres, seat, cutting units); Ł How many hours has the machine done, and does it look in good condition for the amount of hours it has done?

Being registered for use on Ł ; Ł Ł Ł ' \ ii bent greens gives turf managers exceptional and unique use flexibility not available in other turf herbicides. 0.08mm diameter between sand particles decreases due to plugging by organic matter (1, 14, 16, 18). Even with very good turfgrass management, the organic matter content in the surface two inches is often observed to be >3 per cent by weight: 4.4-16.8 per cent (4); 4.7-7 per cent (G. Landry, bentgrass cultivar trial, 1999, personnel communication); 4.5-20.3 per cent (9). The most common conditions that cause excessive organic matter accumulation are; Ł Prolonged cool temperatures on cool season turfgrasses when temperatures are between 0°C and 13°C, where microbial activity declines and organic matter decomposition declines. Cool, humid temperate climates may have such conditions most of the year, while in the southern regions of bentgrass adaptation, this climatic condition may be for five to seven months per year. Ł Use of aggressive bentgrass or couchgrass cultivars that exhibit high rates of organic 120 A T M DR ROBERT CARROW This rootzone profile is of a one-year-old putting green showing the organic matter build-up near the surface. matter accumulation. Many of the newer greens-type cultivars exhibit this tendency. Ł Poor air drainage that allows the surface to remain excessively moist for long periods. This allows for longer periods of anaerobic conditions and stimulates production of adventitious surface rooting, contributing to more organic matter. These are often the secluded greens with many trees in the surrounds, little natural air drainage, and shade on the green surface for a period of time. Ł Inadequate integration of sand to sustain a media where sand is the dominant matrix rather than organic matter. Sand must be applied not just by topdressing, but also in vertical channels by hollow-tine core aeration that remove plugs of organic matter and allows large quantities of sand to be added. Ł Addition of organic matter to the surface as sod (even washed sod), compost, or organic matter-containing amendments. Ł Acidic pH at <5.5, which limits bacteria and actinomycete populations and activity. Ł Maintenance toward rapid growth or thatch build-up, such as high levels of nitrogen use, frequent irrigation, and high mowing height. Ł Low earthworm activity. A second situation suggested to cause problems is when the "nature" of the organic matter changes from structured organic matter (mainly as live roots) into a gel-like consistency as roots rapidly die and cause a rapid 02 stress. The author hypothesised that this sequence of events was the primary reason for SBD in hot, humid climates or weather conditions. The hypothesis was based on field observations of SBD and the symptoms before, during and after the injury. This situation is most likely to occur on a cool-season grass during hot, humid weather that induces rapid root death; therefore, this problem would be more common in the warmer regions of bentgrass adaptation. Root dieback/death occurs every summer to some extent, but microorganisms can sufficiently break down the fresh organic matter to prevent excessive sealing. Under unusually hot, humid weather for one or two weeks or for a prolonged period, root death occurs more rapidly and can induce low infiltration and low aeration (fresh dead roots hold more water and are gel-like so macropore sealing occurs) by altering the nature of the organic matter. The remaining live, but 02 stressed roots, cannot obtain enough water uptake for transpirational cooling because of the low 02. Root cells loss their permeability to water when rootzone 02 is low and, thus their ability to take up water. Low soil 02 in the surface j Bayer Environmental Science MWilHl msmm Summer decline.

A T M 13| SURFACE ORGANIC MATTER IN BENTGRASS GREENS layer where the remaining live roots are present leads to reduced water uptake, stomatal closure, and direct high temperature kill. This is usually evident by yellowing of the turf and death over a one to three day period of hot, humid weather when plant and microbial oxygen demand is very high. The more the organic matter content is above 3 per cent by weight, the more likely a massive root dieback from hot, humid weather would cause a rapid 02 stress and plant death. However, even relatively low organic matter contents of 3-5 per cent seem to be sufficient to enhance SBD as the gel-like material from recently dead roots retains considerable water, and these dead root tissues are very effective in sealing the surface pores in this state. This physical stress basis as the primary cause of SBD rather than a pathological one is now considered by many to be the number one cause of SBD under hot, humid weather conditions (3). It is not the lack of roots from root dieback that is the problem, but the creation of an excessively moist layer with very low 02 during hot weather in response to the rapid root dieback, resulting in inability of remaining roots to take up sufficient moisture for transpirational cooling. In the late 1990s, Huang et al (10, 11) provided strong evidence of adverse effects of the combination of high temperature plus low 02 on bentgrass root viability to support this hypothesis. Also, the author conducted oxygen diffusion rated (ODR) measurements in a study funded by Toro from 1992-1995 within the surface zone and found numerous periods when ODR was less than 20-40mg 02 cnr2 min \ which is considered sufficiently low to limit rooting of grasses. In the very hot, humid summer of 1995, almost all readings were well below this limit. RESEARCH APPROACH USED IN THE STUDY The focus of the research in this study was on management of the second problem - the change in nature of the surface organic matter during the summer months. Research was conducted from 1996-1998 at Griffin, GA on an experimental golf green with the rootzone mix meeting the USGA specifications. Treatments consisted of various non-intrusive cultivation approaches that would not cause surface disruption in the summer, topdressing, wetting agent, sand substitute, and cytokinin combinations. Saturated Hydraulic Conductivity (SHC) One of the most important characteristics for bentgrass golf greens in the summer time is the ability for excess moisture to infiltrate into the surface and percolate through the rootzone.

In Table 1, SHC values at 1-7 and 17-26 days after cultivation treatment are presented with the SHC values an average of seven summer-time measurement periods during 1996-1998. Within 1-7 days after cultivation application, SHC increased at least 3.4-fold to > 20.2 inches per hour for all HJR treatments (HJR = HydroJect operated in a raised position to provide a hole of approximately _ inch diameter) compared to 5.9 inches per hour in the non-cultivated control. The plots that were core-aerated in March exhibited no difference in SHC compared to the control. This illustrates that the effectiveness of spring hollow-tine cultivation on SHC declines over time as holes refill with root mass; and would suggest that cultivation methods that are normally non-disruptive of the surface, such as HydroJect or solid quad-tines, would be necessary to maintain higher SHC during the summer periods. Comparing HJL to HJR treatments (HJL = HydroJect operated in a lowered position to provide a hole of approximately 1/8 inch diameter) at 1-7 days after cultivation, demonstrated that the larger hole formed by the HJR operation was more effective in increasing initial SHC. The LandPride device (dry injection) did not result in any increase in SHC when a sand substitute was injected. LandPride cultivation alone (without amendment injection) was not evaluated in the study. The same sand substitute amendment when applied as a topdressing after HJR cultivation tended to decrease SHC, especially at 17-26 days after cultivation. At 17-26 days after cultivation, all HJR treatments exhibited SHC of 2.2-3.6-fold greater than the control with SHC values of 5.1 versus 10.8-18.0 inches per hour. The lowest summertime SHC observed on the non-cultivated control was 0.8 inches per hour versus >3.2 inches per hour for plots that received cultivation in the summer. The decline in SHC from 1-7 days to 17-27 days after cultivation is expected as the surface starts to reseal from root mass growing across the hole or collapse of the hole. Oxygen Diffusion Rate (ODR) ODR readings were taken in the surface one-inch depth during the summer months for selected treatments and results varied with the year (Table 1). In 1996, readings were <20mg 02 cm-2 min1 most of the time regardless of treatment. There were periods of limited 02 within the surface zone in the other years. These results, plus similar ODR findings from a subsequent study (20), confirmed that critically low 02 levels can occur even under non-saturated conditions. Low ODR levels would be expected more frequently when rain is frequent or daily irrigation is practiced that keep the surface zone moist. A T M SURFACE ORGANIC MATTER IN BENTGRASS GREENS Turf Quality and Shoot Density Improved turfgrass quality and shoot density were noted for most of the HJR and HJL treatments relative to the control (Table 2). The reduction in the turf quality and shoot density of the core-aerated plots occurred in the early summer when some residual effects from the spring treatment were still evident. Generally, when sand or a sand substitute was applied immediately after the summer cultivation operation, visual quality and shoot density ratings were not as high as when the topdressing was omitted. Only the hollow-tine treated plots received spring core-aeration with sufficient topdressing to fill the holes. The surface organic matter accumulation was the least in this treatment, illustrating the importance of hollow-tine core aeration, which allows for more sand to be incorporated into the surface organic matter zone than by topdressing alone. All treatments resulted in organic matter levels above the < 4.5 per cent level desired. IMPLICATIONS FROM THIS STUDY The immediate increase in SHC following cultivation treatment demonstrates that the surface conditions do control SHC on high-sand greens and that creation of temporary macropores across this zone results in SHC that is substantially higher. Superintendents may use infiltrometers to determine SHC on their greens in the field. One question that often arises is whether the field SHC will be the same as the laboratory SHC for the rootzone mix without a turf sod on the surface. The answer to this question is yes and no, depending on: Ł If field SHC is taken at several weeks after a cultivation event and the holes have had time to seal, the SHC can be appreciably less than lab SHC. Ł If field SHC is measured within the time period when the cultivation holes may still be partially open, SHC rate may be intermediate compared to obtaining the SHC rate within a few days after cultivation. SHC measured within a few days after cultivation often is within the same general range as the laboratory SHC if the Ł Hydraulically powered Ł Side arm conveyor (opt) Ł Box scraper (opt) Ł Reversible floor Ł Walking beam suspension Ł Ideal for sportsgrounds and contractors Ł 2 cubic meter capacity (app) When it comes to topdressing the Dakota range of Turf Tenders have no equal.

Factors often observed to alter the SHC below the surface two-inches include movement of salts that precipitate within this zone, movement of fine materials during grow-in into the subsurface or a layer, and a high organic matter layer that becomes buried. That may include thatch that develops during grow-in that has not had sufficient sand integrated into it and is buried with subsequent topdressing. A suggested protocol to determine the SHC with and without the influence of surface conditions is to conduct the field SHC determination using a field infiltrometer and record the value. Then, while the infiltrometer is still in place, push a _ inch diameter solid-tine with a sharpened end to a depth of three inches a couple times into the turf surface within the infiltrometer, then repeat the infiltrometer reading. Do not go deeper than three inches so that the zone that controls SHC can be identified. If the reading is similar to the initial reading but low for both of the above determinations, push the rod in the same holes to the bottom of the rootzone mix (about 10-12 inches) and determine SHC. If readings dramatically increase, this would indicate that conditions from 3-12 inches control SHC rather than surface conditions. But if SHC greatly increases after creating macropores just within the surface three inches, then the controlling zone is at the surface. Another implication of this study is that it demonstrated that when surface conditions control SHC, most cultivation operations that create at least a _-inch diameter hole can dramatically and immediately enhance SHC. But, SHC will then decline over time. These responses have impact on cultivation timing and frequency. Some observations from the current study and other cultivation studies that the author has conducted over many years are; Ł The holes made by HJR, _ inch solid quad tines, and the Aerway Slicer 100 greens cultivation device all initially enhance SHC, but by about three weeks their effectiveness starts to decline with the HJR least affected, probably because a hole is cut out instead of created by pushing materials to the side. This is the basis for suggesting an approximate three-week schedule of non-disruptive cultivation treatments. Personal observation has been that sites receiving appreciable sodium and/or very heavy traffic will exhibit hole closure at a faster rate. Ł When hollow-tine core aeration has been conducted with holes filled by topdressing, the duration of improved SHC is usually five to eight weeks for _ to 5/8-inch diameter holes on high sand greens. Ł The responses just noted would suggest that non-disruptive cultivation should be initiated within five to eight weeks after a hollow-tine cultivation operation and repeated on a three week schedule to maintain high SHC conditions during the summer months. Ł In another study (20) where the focus was not on the summer but the cooler months, we found that the lowest SHC and 02 values came in the December to February period. Since cooler weather favours bentgrass root growth and regrowth from the summer, it appeared that the massive root growth in the surface two-inches essentially plugged the macropores with live roots to the point that water and air movement were greatly reduced. The implication would be that rooting could be limited during this period and until core aeration occurs. Thus, a non-disruptive cultivation application in late winter/early spring before the temperatures are favourable for hollow-tine core aeration and/or an application at five to eight weeks after autumn coring could assist in maintaining macropores for water and air movement in cool periods. The very low soil 02 in the winter to early spring may be a primary reason for the long-term observation that rooting declines in high sand greens after the initial one to two years. Low 02 within the surface two-inches due to high moisture retention of the organic matter means that the lower crown, lower portion of stolons, and roots in the layer are exposed to low 02, especially in wet or humid years where drying of the surface would be slow. Perhaps this is the primary problem that weakens the plant and triggers diseases that are associated with root rot injuries. If so, than primary preventative control measures would be to dilute the organic matter layer, remove some of the organic matter, maintain macropores, and improve air drainage to dry the zone. An excellent article by O'Brien and Hartwiger (19) reports on options for controlling the organic matter zone. One question that arises in their article as well as this study is, 'What is an acceptable level of OM in the surface two-inch zone?' The author's view on this question is based on experiences gained from several cultivation studies, visiting golf courses in a number of locations in the world, and from literature previously cited. These views are summarised as follows; Ł Regardless of climate zone, greater than 4 per cent organic matter content in the surface two-inch zone becomes a "red flag" value that indicates the probability of developing low 02, excessive surface water retention, and reduced SHC. The more organic matter increases above this value the greater the potential for these problems. This level is a guideline to assess the potential for certain problems and to indicate when more aggressive management is needed. It is not a specific level that means turf death is imminent. Ł In the USGA green construction method, organic matter mixed throughout the rootzone mix is capped at about 3 per cent (by weight) since above this level it is difficult to achieve a mix that allows sand to be the dominant media and maintain a balance between moisture retention versus aeration porosity. If the soil physical reasons are true at establishment to maintain <3.0 per cent, they continue to be valid after establishment. Who recommends 4-10 per cent by weight of organic matter within high sand green mixes? Ł Within the southern zone of bentgrass adaptation, the 4 per cent level is especially critical because the opportunities for low soil 02 to occur in conjunction with hot, humid, wet 124 A T M SURFACE ORGANIC MATTER IN BENTGRASS GREENS V^V This rootzone profile demonstrates a putting green that has developed a surface organic matter problem that has limited gas exchange which has led to the development of a black layer beneath the organic matter layer weather are greater. But, such hot, humid, wet periods can also occur during certain years in many cooler regions. Ł I have heard turf managers indicate that the organic matter content in their greens are higher than 4 per cent and they do not see any problems. As noted, the cooler the climate the more likely that organic matter will accumulate to greater than 4 per cent unless a vigorous control program is followed. It is within these climates that SBD is most rare. However, the onset of low 02, waterlogged, soggy greens becomes more dominant over time in these same climates as well as the pathogens that such conditions may enhance. Ł Another reason that somewhat higher organic matter content than 4 per cent seems to occur in some situations (or even at times within a year at a location) without evident problems, may be that much of the organic matter is present as live roots. Live roots have a structure that allows better air exchange and water movement compared to when many of the roots die and the organic matter becomes more of a massive, spongy nature with macropores less defined. Ł Maintaining sand as the primary surface matrix rather than organic matter (remembering that 1 per cent organic matter by weight equals about 5 per cent organic matter by volume) is also important for maintaining a firm surface for putting quality as well as one that will hold the mower without scalping. It is informative to remember that since the very early days of USGA greens and high-sand greens that preceded the formal USGA specifications, the early agronomist recommended twice annual core-aeration plus heavy topdressing at the time of coring (15-20 ft' of sand per 1000 ft' per topdressing). Why would this be the recommended practice except to dilute the on-going problem of organic matter accumulation in the surface? History often has a story to tell us today.

AUSTRALIAN OPEN 2003 -MOONAH LINKS During 2003 we were privileged to have a close association with the Australian Golf Union and Moonah Links Golf Club in the lead up to and during the Australian Golf Open. It was a very interesting and valuable experience to observe all the preparations and goings on at close range. From my perspective, what I was most impressed with was the great effort put in by the ground-staff not only for the tournament itself but also the 12-18 months leading up to the event. It was only a relatively short time ago that the golf course had completed the grow-in and the conditioning period was only beginning. The condition of the turf for the tournament was exemplary given the time frame involved and the extensive area that has to be maintained. In September/October 2002 the maintenance of the golf course was taken in-house, groundstaff had to be appointed and the facility tooled-up. Over the past 12 months the groundstaff have had to condition the Open course for play, complete the grow-in and bring into play the Legends course, construct the Australian Institute of Sport facilities, construct a monster putting green in the middle of the hotel complex and take charge of turfing around the clubhouse and the hotel. All of this was happening with the Australian Open a constant presence. Most Australian Open courses are well established, with the experience of hosting major events and rarely have to cope with the above distractions. The maintenance at Moonah Links is very well managed by superintendent Leigh Yanner with his very capable assistants Scott Calder The spectacular eighth hole at Moonah Links (Open course) and Nathan Bennett (Legends course). The ground staff are hard working and enthusiastic and a pleasure to be around. It was also interesting to see the influence of high profile golf courses such as Metropolitan, Royal Melbourne and Lakelands on the key members of staff. Well done to each and every person involved in preparing the Open course for the 2003 Australian Open. COUCHGRASS MITE DAMAGE During the spring and early summer, couchgrass mite damage has been quite noticeable and in particular where the couchgrass is under moisture stress or has been damaged by disease (in particular Spring Dead Spot). The couchgrass mite is an Eriophyid (Eriophyes spp.) mite that is extremely small -about 0.2mm long - yellowish-white in colour, and worm-like in appearance with four legs. A IM They cannot be seen with the naked eye, and a hand lens is of little help. A microscope is needed to find them on infested grass. They multiply very fast, requiring only about seven days to complete their cycle from egg to adult at ideal temperatures (27-43°C) and humidity. The mites tend to develop between the grass stem and blade sheath; this area protects them and makes spray penetration into this area difficult. They remain for most of their life beneath the grass sheath, and large numbers in all stages of development may be found under infested sheaths. Since the couchgrass mite is so small, it can be identified only by the symptoms of damage to the grass unless sufficient magnification is used. Fortunately, the mite causes a characteristic type of damage. Initial damage is observed in the spring when the couchgrass fails to begin normal growth. These areas may be yellow or brown in colour. Damage appears as a typical resetting and tufting, caused by a shortening of the internodes. The tufts produce clumps or "witches brooms" in the grass. The grass loses its vigour, thins out, and may die. Injury is more pronounced during dry weather and especially when the grass is stressed. In recent observations it has been strongly associated with areas damaged by Spring Dead Spot that are beginning to recover where the mites attack the new growth. Infested grass will have large brown clumps of distorted stems that usually die. Control As with many pests, good irrigation practices, the proper use of fertilisers, and other approved maintenance practices to encourage vigorous growth and good plant health will often disguise the effects of infested couchgrass. However, where the couchgrass is recovering from other problems or it is newly planted stolons, regular treatment with a registered insecticide is required. In some situations with new plantings, treatment every 7-10 days will be necessary because of the rapid lifecycle of this pest. Damage thresholds have not been established for this pest, but if a treatment seems necessary, mow the turf closely and remove clippings first. In addition to physically removing most of the population, it may also displace remaining mites so that they are more readily contacted by the miticide. After mowing, irrigate the turf and spray while the grass is still wet. To increase the chance of getting the pesticide under the leaf sheath, add adequate spreader-sticker to the spray mixture. Do not water or cut the grass within 24 hours of chemical treatment. A second application 10 days after the first may be necessary on established turf to obtain satisfactory control (and more frequently on new plantings). INSPECTION OF ADELAIDE GOLF COURSES AND GMA CONFERENCE In November 2003, AGCSATech undertook inspections of several golf courses in Adelaide as part of an initiative by the South Australian Golf Association (SAGA) and the South Australian Golf Course Superintendents' Association. SAGA subsidised the costs of the inspections and reports as a service to its member clubs. It was a pleasure to inspect the courses and to discuss local issues including water quality and continuity of supply. During the week in Adelaide, Glenelg Golf Club superintendent Daryl Sellar and I made a presentation to the Golf Management Australia (Secretary/Managers Association) conference on the superintendent's role and the future challenges of course management. It was a good day and we had some positive feedback on the presentation. A few judicious photos of the pesticide spill in Manly Lagoon (see Australian Turfgrass Management Vol 5.6) produced a collective gasp as we discussed due diligence and environmental responsibilities, a Couchgrass mite (A: adult; B and C: Damaged and healthy plants) A T M 27| Riordan's River After worrying times, the future now seems assured for the Patterson River Country Club, but achieving it has taken a land deal, clever planning and one very shrewd superintendent. To be a member at Patterson River Country Club these past four years has meant calling on all one's reserves of stoicism. A few gave up and walked away, but every-one else endured what no other golf club in the country has ever experienced - the building of an entirely new course on top of the existing one while the members kept playing. To be course superintendent there? Well that's another matter completely! Meet Michael Riordan, superintendent for nearly 20 years and possibly just a little bit greyer than he was when he scored the job at Patterson River back in 1999. It has been an extraordinary feat to say the least, but the end is in sight with construction due to be finished by the end of March, an incredible 12 months ahead of schedule. "It has been a challenge but one which has been hugely rewarding," says Riordan. "We've still got the entire 13th hole to do and 9th green but the finish line is in site. Everyone can see what the finished product will be like now and everyone's very pleased with it. "The further we go the better we get at doing things. At this stage it is making sure that we don't take any shortcuts to finish it on time." To keep the course open throughout was a seemingly endless test of ingenuity, determin-ation, perseverance and much hard work. Almost from the moment the earthmovers and giant tip trucks began assaulting the old 6300-metre, par 73 layout, members and guests were confronted with an ever-changing, contrived course. Anyone returning from a long holiday could have been excused for losing their way around the track, but Riordan and course architect Phil Ryan, from Pacific Coast Design, ensured 18 holes always remained in play. And in all the re-jigging, members have played briefly to only one temporary green and played off two temporary tees. GRAHAM ECOLES & BRETT ROBINSON Club captain Peter Bleazby is high in his praise for what Riordon and Ryan have achieved. "They have done a mighty job." For Riordon it was a case of the wheel having turned full circle. After serving the earlier part of his career at Patterson River, he left in 1985 and went to Whittlesea until 1989. From there he moved to the Mornington Peninsula and acquired the job of construction superintendent at Eagle Ridge. It was the experience he gained there that landed him the superintendent position back at Patterson River in 1999. "At times it has been tough but I've been a superintendent for nearly 20 years and I think you would have needed a bit of experience behind you to do something like," says Riordan. "There are lots of pressures, lots of people want to push you around, and being able to take no shit from anyone certainly helps. "But the club really went out on a limb doing this. For them to stay competitive in the Melbourne metropolitan region they had to do something pretty radical and that was to get their turf surfaces up to the quality of other clubs in the area. " I worked here as a kid so I sort of knew what the problems were and what was going to be involved. The job has been bigger than what I thought when I applied. I would have put another $50,000 on my salary if I had known!" The mammoth operation began back in November 1999 shortly after Riordan came on board. The first thing he did was plant a hectare nursery of Santa ana before embarking on the first three holes (14, 15 and 17) in February 18th Island green at Hidden Valley G&CC.
