End of Season Aeration

Once again we have arrived at the time of year when our most intensive period of aeration takes place.

Aeration is one of the most important maintenance tasks carried out on turf. The word aeration means quite simply to get air into something. In turf it is simply the production of holes through the turf surface into the underlying rootzone (soil) to allow gases (oxygen etc.) in and out of the soil and for water and grass roots to move down through the soil.

Starting this week we will be running two verti-drain type machines over all areas of the course. Fairways and high wear walkways will be tackled first. For these areas we use twelve 18mm x 300mm solid tines on each machine(see pic above). This allows us to make lots of holes in the turf and at sufficient depth to enable the movement of water more quickly through the soil beneath. The action of these particular machines also allows a certain amount of "heave" to be put on the soil. This lifts the level of the ground slightly allowing air and moisture to penetrate and relieve compacted areas. Compaction in the turf is caused by the regular movement of people or machinery over an area, wet soils compact more easily as the water in the soil acts as a lubricant allowing the particles to slide closer together and form a bond.

Next week we will start on greens and green surrounds. For these areas we will use a tine which is smaller in diameter but of a similar length. This smaller tine, coupled with some lightweight rolling will allow quicker recovery of the turf in these key areas. We hope to repeat this process in greens and surrounds in February 2010 and in future every October and February.

Course Update

Maintenance Week

The greens have recovered well in the past few weeks from the hollow core aeration work that was carried out in early September. It was obviously rather painful for all players when there were so many holes in the greens, with putts bobbling and bouncing across the surface it was easy to forget just how important a robust aeration programme is to the future performance of the greens. The course team have worked hard to reinstate the surface, a total of 45 tonnes of top dressing was applied to greens in the three weeks following the coring work and this has had the desired effect. This amount represents almost half of the annual total top dressing used on greens, so to apply this in such a short space of time took considerable effort. Whilst the holes were in the greens the opportunity was taken to introduce more grass seed into the greens and it is pleasing to report that this has taken well. The severe disruption to golf this aeration event caused has been noted and as a consequence next year’s maintenance week has been moved to the end of September.

Irrigation

The rain has finally arrived after an extended dry period through August and September. Following comments from a number of members I would like to briefly outline once again our watering strategy for this summer past and for future years.
Whilst we aim to provide evenly moist soils with optimal growing conditions in the spring, early summer and autumn periods our approach changes in mid-summer. In order to impart drought stress on the undesirable broad leaved grass species in the greens, we make a conscious effort to allow the turf to dry out in the peak summer months, thus creating an environment in which the desirable grasses can thrive and gain the upper hand. It is crucial during the summer months that this happens otherwise the broad leaved, undesirable grass species will continue to dominate putting surfaces. It also allows us to present a firm and fast running golf course, just as one would expect from a links course in the middle of a dry summer. You might be surprised to learn that to keep the course as dry as it was actually took quite a bit of water. In the period 1st July to 30th September we used a total of 21,400m3 of water, that’s 21.4 million litres or 4.7 million gallons to water greens, tees, surrounds and fairways!

Broadleaved Grasses In Greens

Ryegrass and Yorkshire Fog grasses are present in many of our greens. These are wholly inappropriate putting green grass types that have proved notoriously difficult to eradicate. Thankfully a new chemical has been released to the amenity market that selectively controls these species, killing them off without harming other plants. We decided to trial this new product on the 4th and 6th greens and on the 4th yellow tee. Spraying took place on the 8th October and we expect to see the grasses start dying off within a few days. We may for a period have some thin areas of turf on these trial plots but the areas will be seeded and top-dressed until good grass cover is restored. If this trial proves successful we will roll out this program over larger areas in the future.

Upcoming Winter Work

The main project planned for this winter is the redesign of the chipping area. We plan to build a large green in the centre of the area to facilitate a range of short chip shots from a number of players simultaneously. To do this we will dig up three of the existing greens, re-shape the ground and then re-lay the existing turf. The green that is located nearest the 18th fairway will be left in its present position but will have another bunker added and the existing bunker enlarged. The chipping area will be closed while this work takes place and will remain closed until all the turf knits together properly.

More trees will be felled as per the ecology plan. White paint distinguishes the specimens due for removal this winter. The invasive Holm Oak will once again be targeted but also some of the Macrocarpa trees in the dunes between holes 11 and 13 will be felled. This policy of tree removal is in line with the States policy for the neighbouring land.

Also this winter we plan to refurbish a number of bunkers around the course and also extend the 5th tee. As usual, solid tine aeration will take place on greens, tees, surrounds and fairways.

Going forward, a monthly update will be published to keep members informed of what is happening as regards the golf course.

Maintenance Week

Members should note that from Tuesday 1st September until Friday 4th September we will be carrying out intensive maintenance on the course. The main tasks scheduled to take place include- hollow coring, pencil tining, overseeding and top dressing to greens. This work is being carried out to help control thatch build up in the greens and to improve the movement of air and moisture through the soil profile.
To ensure the work is completed in a timely manner one tee starts will be used each day and holes may be closed for short periods. Any disruptions to the normal flow of golfing traffic will be clearly signposted.
I would like to apologise for any inconvineince this may cause players during this busy time.

Well Done Ollie!

We are very proud to announce that Ollie Pennington has reached the national final of the 2009 Toro Student Greenkeeper of the Year contest. Ollie is almost finished his Amenity Horticulture NVQ level 3 course that he has been working on for the past 18 months. Due to the consistently high standard of Ollie's work, Nick Lush his tutor at Myerscough College, nominated him for student of the year. Out of over 1000 students studying turfgrass related subjects 45 were selected to attend regional finals. Following the completion of a questionnaire and an interview with industry experts Ollie was recently informed that he has been selected as one of eight national finalists. This is a tremendous achievement for Ollie and in fact a great boost for all the course staff here at La Moye.
The final itself will take place over two days in September. The finalists will be asked to carry out an in depth and detailed appraisal of a golf course which is to be submitted in report form. They will then be questioned on the contents of their report by a panel of top industry figures. From this process a winner will be selected and will receive the grand prize of an eight week trip to the USA which includes a six week residential scholarship to the University of Massachusettes, to attend the winter turf school. The winner will also be given the chance to tour Toro headquarters and join the BIGGA visit to the GCSAA Golf Industry Show in San Diego in February 2010.
We all wish Ollie the best of luck in the final and well done again for getting there, a major achievement of which he should be really proud.

It's The Greens That Count

If you were to ask anyone what they thought of course condition on completion of their round they are likely to talk mostly about the greens. The greens are commonly said to be either good, bad, too fast, too slow, too firm, too soft, too bumpy or have too many holes, slits or grooves! It would be fair to say that it's that greens that count most.

Work on greens this season has been focused on increasing the amount and density of fine fescue and bent grasses in the sward through carefully scheduled fertiliser and water applications coupled with overseeding. Also, to impart cultural and mechanical stress on the Rye and Yorkshire fog grasses to refine the texture and grain of the sward. We have also tried to improve the quality and consistency of the rootzone immediately beneath the turf to equalise the bounce and roll characteristic from one green to the next. Eventually this type of work will give consistent, true putting surfaces that remain of a good standard for the majority of the year.
While this work takes place we are challenged to present the greens to the highest possible standard for each days play. Inevitably on occasion, particularly after periods of stress, the greens in their current state will fail to live up to expectation.
We plan our aeration, top dressing and brushing programmes around the major competitions of the year. This means that between those competition dates we must carry out these procedures that disturb the quality of the putting surface for a short period. Due to the constraints and pressures of the diary we are inevitably compromised when trying to find a balance between short-term performance and long-term improvement. If we do not carry out these necessary operations then nothing will improve. If we only focus on short-term putting green performance then nothing will improve. A balanced approach is being sought which allows the greens to perform to a high standard when absolutely necessary but also allows our fundamental and long standing problems to be addressed in the appropriate way.

Long, Thick Rough!

As usual at this time of year, the uncut roughs on the course have become long and thick. Some players feel the course becomes too difficult at this time and we are regularly asked to cut extra sections. I feel it is worth reminding everyone of our rough grass management strategy and explaining the reasons behind our actions or even our inaction!
Our approach to the management of the rough sets out to balance the needs of the golfer with the needs of the grass plants and the needs of the diverse array of flora and fauna that inhabit the rough grasslands. We are very fortunate that we are able to play our golf in such a wonderful, natural environment and it is a prime objective of the course staff to protect and enhance that environment. The rough grasses here at La Moye are very delicate and must be treated carefully. Only in the late spring/early summer period do they get a chance to grow properly, set seed and thicken up before the summer droughts come in to thin out the grass naturally. This cycle takes place every year and it ensures we have good grass cover throughout the year providing crucial definition between the holes. If we cut too much rough at this time of year we will remove this important aspect of the course character.
Also, the rough grasslands are the most species diverse areas of the whole golf course and as such are the most valuable from an ecological point of view. Our roughs provide the perfect habitat for a vast array of flora and fauna ranging from the green lizard to wild orchids with thousands of things in between.
That said, the single most important consideration is ensuring the golf course remains playable and enjoyable for all levels of golfer. To do this we aim to maintain landing area widths of between 30 and 55 metres. This includes a fairway cut at a height of around 15mm, a first cut of rough at 25mm and a second cut of rough at a height of around 100mm. This ensures that well placed shots are rewarded with a good lie but errant shots are punished incrementally. We think this gives the fairest course set up possible.
The recent weather has given us firm and running conditions on the course of late and this coupled with the height of the rough and the wind has made for some challenging golf. Thankfully the conditions will ease in the next few weeks as the rough dies back and in fact the start of this process is already well underway.

Of course, this is just a sample of the type of work we carry out in an average week in May. As you might expect we spend a large chunk of our time working on the greens. You might be surprised to learn we spend almost as much time maintaining bunkers. Many of the tasks mentioned above are repeated every week but others are only carried out periodically. In other weeks we may well carry out different types of aeration such as solid tining or deep slit tining and different areas will have fertiliser applied or be sprayed. Also countless one-off tasks arise which need to be addressed, sometimes these are the jobs that take the most time.

Spring Maintenance Week

Our first annual spring maintenance week commenced on the 30th March. I'm happy to report that all planned tasks were completed successfully despite a frost delay on the Monday morning lasting three hours. Thankfully no further frosts were seen during the week and scarification, overseeding and top-dressing work took place.
The main task carried out was overseeding of greens, this takes place to improve the overall grass species composition in the sward. Three varieties of Fescue grass were used. These particular plants have the ideal characteristics for golf green purposes and increased numbers of fescue grasses will dramatically improve the year round conditions on the greens.

Having identified the need for new seeding equipment last year and following a lengthy evaluation process we finally purchased a new seeder in March of this year. The Vredo Super-Compact seeder chosen represents a significant investment by the club but one which will benefit the golf course for many years to come.

The new seeder on the 9th green

The machine works by using two rows of metal discs spaced 35mm apart which make thin slits in the turf into which the grass seed is delivered. The rear roller then passes over the slits causing them to close up to reinstate the playing surface. This method ensures the seed is placed to the correct depth and that good seed/soil contact is achieved. Seed wastage is kept to an absolute minimum using this method and given the costs of high quality sportsturf seed mixes this can only be a good thing.

The metal discs making the cuts into the turf


The seed lies safely in the bottom of these slits

The lines in the turf in the photo above will shortly be full of newly emerged young grasses so management practices will be tailored to ensure these are protected in the short term.
We plan to overseed greens at least four times each season using this method. During periods of good growth and following an application of top dressing the slits disappear very quickly and surface uniformity is not compromised. In the coming months and years the machine will be used for seeding other areas of the course such as weak fairway areas, walkways and roughs.

Irrigation

In the coming months one of the most important tools the course staff will use is the irrigation system. Our system was manufactured by Rainbird and was installed in 2007/8 by MJ Abbott. It covers all greens, tees, surrounds, fairways, some rough areas, turf nurseries and the chipping area. There are six boreholes which keep the 1 million gallon capacity reservoir topped up.

1 million gallon reservoir

Three large pumps distribute the water around the course at a pressure of 150 psi through a network of pipes up to the irrigation sprinkler heads. The system has been designed to ensure that water is applied accurately and wastage is kept to a minimum. Low trajectory sprinklers are used in the most exposed spots to ensure the wind has a minimal impact. A central computer located in the maintenance facility is used to program and run the system.

Mission control!

The course has been mapped using GPS with every sprinkler head, valve and pipe marked. Any sprinkler head can be turned on either at the base station, manually at the head or by using a remote control unit. The system can be programmed to run any number of heads in any sequence starting at any time.

Record keeping is made easy with this system as it automatically maintains detailed records of application timings and quantities giving weekly, monthly or annual aggregated totals. A weather station is also linked in to the system providing real time data of wind speed and direction, precipitation, humidity and temperature. From this information evapo-transpiration rates are calculated which the system can use to determine how much water should be applied to maintain optimum soil moisture levels.

Daily weather records are automatically maintained

As you can see, our system makes it easy for us to apply water accurately and at the rates we want. However, we must remember that this does not mean we always want the golf course to be green and lush. Inappropriate and overuse of the irrigation system can cause serious long term problems to turf which can take years to rectify. We aim to use the system only when the health of the desirable grass plants would otherwise suffer, not just to soften the greens so the ball is easier to control or to green up the fairways to make them look "nice".
In late winter and very early spring we rarely irrigate even in extended dry periods because the cold water only serves to lower soil temperatures causing what little growth we have at that time of the year to stop completely. Much better dry, firm and slow growth than moist, soft and no growth! We generally irrigate in all dry spells throughout the mid-spring/early summer period to ensure the turf has optimal growth conditions to recover from the stresses of winter. Once mid summer comes we will relax the irrigation to allow the turf to dry out somewhat in order to stress the undesirable grass species and to encourage the fine grasses to develop deep rooting. Without doing this the shallow rooting grass species - which also happen to be the least suitable grasses for golf - are allowed to colonise and take over the sward. In general terms we are trying to present firm and consistent surfaces which have a dense cover of fine grasses. Our watering strategy is tailored with this in mind so please don't be surprised if surfaces get a bit brown in colour come mid summer, it will not mean the irrigation system is broken, we will merely be letting nature take it's course!

Broken Tee Pegs

The broken tee pegs picked up from the course today

In an attempt to keep the golf course as litter free as possible, we are aiming to address the issue of broken tee pegs. Every month we spend many hours picking up broken tee pegs from the tees. Not only do they look unsightly but they also knock the mowers off cut, potentially causing damage to the grass itself. To try to combat this one of the tee markers on each of the tees has been replaced with a tee caddy (see pic. above). It is hoped that all players will use the tee caddy to deposit their broken tee peg after they have played their shot thus maintaining a tidy appearance to teeing grounds and helping to keep our mowers sharp and correctly set to ensure minimum injury to the grass plant.
