Merry Christmas to you all

Merry Christmas to all of our Stoneham members. Hope you have a great Christmas break and manage to get some Christmas golf in during the festive season from Matt and all the greenkeepers. 

Playing the numbers game!

Golf is one of those sports that's all about the numbers. It's normal 18 holes numbered 1-18, it has a Par, Stroke index, scores, number of players, numbered balls and even rules by number!! Driving stats, greens in regulation, putts taken and ball trajectory are all parts of the game now. We even use GPS to know our exact distance from the flag so we can hit that 132.5 yard shot we have in our bag!!

Anyone who's played with me will know there is always potential for a high number to appear on a score card too

 :-) 

So it should be no surprise that we the greenkeepers are obsessed with numbers too. 

Some of these maybe obvious things like the speed of the green using a stimp meter. This is tool for greenkeepers use to set the speeds up for the golf of the day. (I will blog more on this as its a big subject). It helps us give more consistent greens. It's important we don't use this as a weapon to just drive speeds as this can have a detrimental effect on the grass plant itself. I mean the golf is meant to be played on grass not soil. Always remember the saying 'the quick and the dead!'.

Another number count we are collecting is grass density. This is carried using a 1 inch square on the green and me on my hands and knees counting. This helps to show me if fertilisers are giving what we want (too much or little). 

We also look at how many boxes we have cut off certain areas of the course almost daily this is called clip rate. It can be measured into jugs and weighed or just a simple counts of boxes. 

I measure GDD (growth degree days and Growth potential). These help us to show how the growth is changing on us and helps us correct it. This is based on a maximum v minimum air temperature, then we get the mean and minus the base number. 

The base number is set by the temperature the grass plant starts to grow at. 

Growth potential helps to show when the plant is going to grow and its rate on the day. It could be 10% or 100% depending on the figures but it's always best practice to apply when the plant is more likely to take the product (food) on through it cells as it grows. Above shows the growth potential since from October- December you can clearly see we have only had one cold spell so far this winter. 

Soil temperature are measured for growth rates and how to aid them if possible. 

Rainfall figures are collected daily. This gives us a good comparison day on day, week by week, year by year. We know for example that we had 82mm of rain in November 2015 compared to the average of 76mm but compared to last years 104mm it wasn't to bad but we ve had 380mm between August -November, now that's wet but it's still none stop as we head to Christmas!! 

This data also shows us how many rain days compared with previous years or months. Remember sometimes the amount of rain days can be more of a problem than rainfall. This is because the plant/soil doesn't get time to dry out causing more issues. 

November was also the dullest on record for the last 80 years with a total of 36 hours of sunshine total for the entire month. Light levels is one of my next data collection list.

Moisture levels are measured too. All year round. This helps us to keep the plant alive in the summer (at that point we look at ET rates, evaporation) to get an even number throughout the day. In the winter this can indicate poor drainage, when work is required to increase air in the profile and where our problem areas might be. 

Below you see photos taken while testing  the green. After getting a high reading off the surface I wanted to test the soil profile to see where the problem area was. This showed the moisture content at the bottom of the hole cup to be 22% (dry) the middle section was 36% (medium) the top 38% (still medium but slightly high) the surface reading was over 50% which is very, very wet indeed. 

The results of the test showed the moisture was holding at the surface rather than in the soil. This was good to find out as wet soils need drainage but wet surfaces need OM removed or deep aeration. 

We then decided to slit tine as this would allow a deep aeration but wouldn't open up the surfaces allowing more rain into the profile. This reduced the moisture level instantly giving us breathing space from any problems. This just showed how using the data can improve our surfaces and how it helps shape our decisions. 

We measure infiltration rates (the speed water moves into the soil profile) & percolation rates (the speed it goes through the soil profile). 

Things you might not have thought of...

Our machines are measured in hours not mileage. These are recorded daily as part of the pre start check sheets and these hours are monitored for servicing and life expectancy of machines. 

The machines have a different number of blades, different thicknesses and a number of different units. Depending on the area to be cut. Our greens mowers have blades like razors with up to 15 blades, tees and aprons use 8 blades and so on and on to our rough mowers that use rotary blades. 

Our heights of cut or HOC are measured in mm. We look at heights of cut in the terms 'bench' (bench set) v 'actual' heights (on the greens using a prism).These can be adjusted daily if needed and adjusted on greens to 0.05 of mm and that can make a difference to the ball roll. Madness I know!! 

The changes can be made for performance or weather reasons. The quality of cut is monitored daily. This is checked in the mornings as part of our starting checks and we also use magnifying glasses to check the quality. If needed cutting blades are sharpened using grinders or back lapping (another whole blog to come but they are spun in different directions one is ground off to sharpen the other spun the other way and paste added to get an edge to cut from. They have the correct cutting angles checked hoc checked and put back together each time. 

Staff hours- simple yes but we record details of where we spend our time and how long things take. This helps us to plan better and to keep working to be more efficient and effective. 

Interesting: the data shows we spent over 27% of our total staff hours on greens since June which isn't surprising as its the main playing surface. The data showed we spent more than 500 hours cutting greens in the last six months (helped by the mild Autumn) and over 300 hours on aeration. I don't expect either of them to change in the coming years. If anything that figure will increase as we look to increase performance. The purchase of new machinery will aid better quality surfaces as the modem machines have a better cut quality. Aeration recovery will be quicker as the machines on order will speed up that process. For example the top dresser can carry twice what had before but the same weight per wheel as before. Meaning less time filling up. So the hours are going to be spent better. 

 Bunkers come in a close second with 19.8% of our time. 160 hours were spent just edging bunkers (that's one member of staff edging bunkers for 40 hours a week for a whole month since June!) and this is a hazard. To help us improve this next year we have purchased some new Strimmers to allow more of us to help spread the load and get finished before the golf. We lost a lot of time this year waiting on golf as we didn't have enough Strimmers to stay ahead. We will also be using growth regulators on these areas too. 

Another interesting note is Course at 12%. Course is just time spent clearing leaves either by blower or trilo off the course. That's roughly 800 hours of picking up leaves. That's 100 working days since October spent by the team on that dreaded leaf wars. 

Now what would have been interesting would have been the data from leaf clearing in the past. Now the woodland project has been carried out and the purchase of two machines which are used for leaf clearing that I know from previous experience are much quicker than the older versions. How much time have we saved? Is there anywhere or way we can improve further? 

We have recently measured noise and vibration on our machinery. This is for the health and safety of staff as vibrating machine can cause life changing illnesses. These tests can indicate how long staff members can do various tasks and when they will need to break and rest. 

We also use data tags on any of the machines that have high exposure limits so the operators know how long they can be exposed to before swapping tasks or resting. 

Other testing includes soil analysis and planning of nutrient inputs. These give us a snapshot of what is going on in the soil and with the thatch levels. From this we can plan our fertiliser programs for the coming year. We can then look at the club diary and plan our applications around that. 

We do this so the growth rates are dropping away when the major tournaments are on so greens play better  on the day as the growth isn't slowing them down. We aim to spoon feed (little and often) the greens to try and minimise flushes of growth and give us an even growth. For example this year our data showed straight away we preformed better during the club championships with less Nitrogen being applied in our mix. Moisture levels were also slightly lower than other tournaments (due to rain) so I got to see an ideal set up and one we have set as our target. 

Aeration also is a numbers game. We plan and look at tine sizes, styles and spacings to workout how much top dressing we need to get on or surface area we wish to hit. This coming year for example we wish to carry out two big hollow cores, six smaller ones and two deep scarifications. This will effect 86% of the surface area. Now that's a high target but it can be done in a way to minimise disturbance but the results of we achieve our target will be amazing. 

Even our sands for bunkers, top dressings and rootzones are all checked. Particle sizes, depths and bulk density are taken into account and planned into our schedules to achieve our goals within budget. 

Sprayer set ups are also number intensive. Chemical mixes, pressures, nozzle selection, area, speed, wind, drift and jug tests (I will explain in another blog) are all taken into account before we start to spray. Calibration sheets are done and records of what has been sprayed recorded. This is a legal requirement for some sprays but also good practice. We also have trial areas at various parts on the course where we will or won't apply things and test to see if they are working. From this decisions can be made to see if the investment was worth it and we got what we required from it.

I hope this little blog has given you an insight into some of our numbers that we the greenstaff are constantly dealing with to improve the course. I know talking numbers isn't always fun but the data we are collecting now will shape the future. 

One thing this winter has already taught me about Stoneham is where our next projects need to be (for example draining the 17th fairway)  and how we improve areas year on year. I have some data to start now and have already started to use it to improve us as a team. 

The greenstaff are great at collecting information and are using it too. 

There is so much more I could add to this blog but it might bore you even more. Like so many jobs there are hundreds of parts to our job (including health and safety and that's an even bigger blog to come) but I will still get asked the question I always get asked. 

What do you do? I am a greenkeeper... Oh you just cut grass then... At this point I laugh with them and just say YES... It would take to long to explain :-)

The Battles of Winter

The meteorological calendar says that winter begins on the1st December. I know this is true, especially this year as it only seems like yesterday we were playing golf in polo shirts and basking in the sun, well that's not far off the truth because November started off so mild (see graphs below). One thing for sure is the battles of winter have officially started! 

One of our main battles is leaves! 

Now as a golfer there is nothing more annoying than hitting a good shot, getting your line and walking up to that area to lose the ball under the leaves.

But as greenkeepers on courses with plenty of trees will tell you there is nothing more annoying than leaves!!

With the mild autumn slowly cooling down and our first few frost days appearing we are carrying on our daily battles with the leaves. 

Some of you may have noticed our presents in the mornings as the greenstaff try to clear the greens and as much of the course as we can in front of play. 

The fact that shorter day light hours, with sunrise around 7.30am, means we start on the course a lot later than in the summer even with lighting rigs. We then try to work in hole order to keep a head of the golfers off the 1st tee. 

Please bare in mind that we are also trying to get all the normal works done along with the leaf clearing during this period and we maybe seen more at this time and may require you to wait for a minute before playing your shot but this doesn't last to long. 

The winter solstice is only days away and then we will start to get more day light hours (slowly). I am definitely looking on the positive here :-) 

So what battles are we facing at the moment?

For a start finding greens covered in leaves every morning!

We then hand blow the greens off. We do this by hand to reduce the amount of compaction to the greens that the other blowing machines would cause especially over the winter. 

Once the greens are clear we then blow the green surrounds and aprons. 

Getting it far enough away for us to get the bigger blower around it to blow it into lines. 

We then use the bigger blowers to move the leaves into lines along the fairways 

These are then sucked up using our brush vacuum or Trilo. The Trilo is another new addition to our fleet and is basically a huge Dyson.  

This sucks the leaves up and shreds them as it fills the back container. It takes longer than you think to pick up all the leaves on the course and the new Trilo is amazing and will speed up

on the old process. 

This should take us between seven to ten weeks to get them all up depending on the Oaks. I believe we are over half way already. 

These are then taken to areas for us to compost them (up to 10 loads a day). This area was recently tidied up using 13 ton digger and driver to give us more space (thank you Mr Trant). 

We also use the hose attachment on the Trilo to clear the ditches. This is a two man job and can take all day. So it's about trying to find the balance and keep on top of the key playing areas. 

(Normally by this point the wind starts to blow, just like this four day weather warning and we start the whole process again) 

I hope this gives you a little insight to what we are doing to clear leaves. I have heard people say the greenkeepers just blow them and they come back. Well as you can see there is a method in our madness but sometimes we need to get round first to allow play then fall back to do the clearing up. 

Rest assured we are clearing them and a lot of man hours are going into this. With each oak tree having around 300,000 leaves falling from it, imagine how many leaves we are picking up!! 

In a few weeks they will all be down and tidied away and we can start thinking about next season. 

I will blog again soon in another prequel of the Battles of Winter but I hope this helps you to understand one of our challenges at this time of year. 

Happy golfing

Breaking eggs to move forward!

Some of you will know the saying 'You can't make an omelette with out cracking some eggs'. 

Well this week we have been cracking eggs so to speak. Sometimes what can been seen to be taking a step back is really important to move forward. 

For example this week the aprons, fairways and semi roughs were all verti drained. This is a deep tine aeration using big 1 inch tines width going 10 inches plus depth.  

This is done to improve drainage, get air to the root system, improve root mass, increase grass coverage and to aid some of our spraying techniques. 

The downside is it can mark up in some of the wetter places following the last few very wet months. It can leave wheel marks. These are superficial and will be gone once the course is cut next.  

This work is essential to help us get through the winter months and have improved fairways in the new year. 

As you can see above the tines do get worn down as the are used so these are changed during the weeks work. 

I mentioned above the fact the verti drain helps aid our spraying techniques. By this I mean at this time of year the course is sprayed for worms (and worms are a problem at Stoneham) to help us tame the beast. This is a chemical that doesn't actually kill the worms but suppresses them down and stops them casting on the surface. This inturn reduces turf diseases, weeds and muddy areas (and annoying mud stuck on your golf ball).

As mentioned in other blogs the thatch levels on these areas is something we are  tackling but are higher than I want. So by following the verti drain we can get more of the chemical we need down past the thatch layer to our target area in the soil. 

Spraying the course is a big job but made harder by leaves and the amazing growth rates going on at present (it's growing as fast as Spring but wetter). For this we used contract sprayers who came in sprayed the entire course by 10.30am meaning the were out of the way from golfers but they also competed it in this rather than our two days in house! See above the two operators. 

Again you may see some wheel marks in places but this will wash out with the next rainfall but it is essential we try to reduce the worm casting through the winter as this has a huge impact on the playing surfaced going into next year. I apologise if this weekend you do land in a wheel mark but you can claim relief and I wouldn't do the work unless it was completely necessary.

Other works this week

While we were verti draining the course we got to use the Gwazae from Bill our Verti drain guy. This is another deep aeration tool firing compressed air into the greens. 

This was carried on the 13th and Putting Green. The reason we done this to those greens was due to the high moisture content in those greens. Our moisture readings were around 47%. Now that is very wet and shows me that we need to work on these areas in the future. Soil structures that get over 50% are in real trouble of getting hypoxia this basically means they drown and it can effect grass sward and colour. This is something we will keep an eye on. 

Using the Gwazae was to good an opportunity and the work was completed in a couple of hours. The benefits from this where - 

-	Greatly improved aerobic conditions
-	More playable days
-	Minimal surface interruption
-	Healthier turf Also our new hand mowers and trailers arrived this week giving us better machines to maintain the course during the winter months. This reduces the amount of compaction on the greens with less wear and a better quality of cut. They even come with lighting rigs.  To say I was very excited about these arriving was an understatement!!  I will blog more on the new machinery and the effects these will have on the team soon. The club are investing heavily in improving your course. The works being carried out are always essential and for the benefit of the club even if first impressions don't show it.  Anyway enough from me. Enjoy your omelette and your golf!  Matt

A Quick Guide

I just wanted to do a quick blog to talk about a couple of things you (and me) as the golfer could be doing this winter to improve the golf course...

Please DO NOT CROSS the trolley lines with Trolleys. 

These have been introduced to protect the aprons and surrounding areas.

Doing this will help to give you better grass coverage on these areas especially in the season and will inspire you to hit those stunning approach shots (or the long putter if your me :-) 

Follow the trolley lines and go around the green. Please don't try and squeeze in between the bunker and the green. 

We have started to use Rope Pins and rope in certain areas to add even more protection. Please follow these diversions as they in place to stop you getting covered in mud also. 

If you take a rope pin down to hit another perfect chip please replace it where you found it. 

I must say we have the most amazing rope pins you are likely to see. These aren't any normal bog standard rope pin. These are hand crafted and beautifully made by one of the Stoneham members (thanks John).

PLEASE make every effort to CARRY YOUR BAG if possible.

Now with the introduction of the rope pins it's a shorter walk carrying a bag. If you possibly can carry please do, you may want a smaller bag than pictured above.

It's your course let's try to protect it for as long as we can and go into the season next year in better shape. 

Please rake bunkers after you have played your shot. 

And if your out with the a trolley and it goes off 'out of control'. Please rake that after also!! :-) 

At this time of year even the slightest shot into a green can leave a pitchmark.

Please repair your Pitchmarks 

Above is a diagram of how to do it. 

Work the pitchmark in from the outside all the way around until them meet. Then flatten normally with a putter.

(Please don't lift from the bottom up as this just leaves a soil mark, this is then susceptible to disease or weed damage).  

Please be careful walking on banks, slopes and sleepers.

During the winter banks, slopes and sleepers can be slippery if wet or icy. Please take care while walking around. 

Story time 

A great professional once told me his aim was to improve the course every time he played. I remember thinking, what did he mean? So I asked him. 

He told me he always tried to repair two pitch marks per green, raked any bunkers he went in and replaced all his divots plus others. He would also pick up any debris or litter if he saw any out the course. 

That's why in my book he was a great professional and great golfer. He left it in better condition than when he played it. 

This should be all golfers mission statement!
