Key Tasks for March
General Maintenance
Good news for grassroots rugby, with the easing of restrictions on outdoor sports at the end of March.
A priority at this time of year is some aeration work to increase aerobic activity and get some much needed oxygen around the grass plants' root system, providing you can get the equipment on the pitch. Regular spiking and, if possible, the introduction of sand dressings will definitely improve soil/water movement in the top 100mm of your pitches. So, if there is an opportunity to aerate, then do it.
Surface levels may need to be restored in areas where scrums have occurred, by light topdressing, seeding and raking over. Infill any holes that have occurred in the pitch surface with a sand/soil and seed mix. Lightly roll after repair work, preferably with a pedestrian mower.
Keep up with the dragbrushing/matting or harrowing when conditions permit, for dew and wormcast dispersion and to help stand the grass up prior to any maintenance work. Repair divots as soon as possible after games or training, with particular attention to the scrum and line out areas.
Using a pedestrain box mower (cylinder or rotary ) will help clean and prepare the surface for matches. If you do have any grass, maintain sward height at 25mm-75mm. The top height will cushion heavy falls on hard ground. Ensure your mowing blades are kept sharp and well adjusted. Cutting grass in very wet conditions can often be detrimental to the playing surface. The mower may smear and damage the surface, especially when turning. The quality of cut can be affected if the grass is very wet.
Repairing and replacing divots after matches is an important part of the maintenance programme to restore playing surfaces. The use of a hand fork to lift depressed turf, and gentle pressing with the foot, is the best way to return/replace divots, however, on larger areas the use of harrows will help return levels.
Marking out is done as required. Playing pitch surfaces can often become muddy and very wet, which may sometimes affect the performance of wheel to wheel transfer line marking machines. To overcome this problem, other marking systems are available. Pressure jet and dry line markers are able to produce lines on uneven and muddy surfaces. Care should be taken when initially marking out new lines, ensuring that they are true, straight and measured correctly, using the 3,4,5 method to achieve accurate angles. Always wash down the machine after use; if you are not likely to use the machine for a few days, it would be advisable to empty it. Particularly with spray jet markers, keep connections clean; spray with WD 40 to help keep it protected.
Pre and post match routines - for those who are playing
Before the match
- Check that the pitch is fit and safe for play
- Check for debris (glass, stones etc.)
- Clear away leaves – a thankless task, but one that needs doing
- Ensure the surface is firm and not saturated, correctly marked out and flagged, and that the posts are safe and secure
Post match
- Replace divots, even if it’s just the worst affected areas - it will make a difference!
- Dragmat/brush/harrow to restore playing surfaces and remove worm casts
- Clean up the playing surface with a rotary mower
Additionally ...
- Plan ahead for end of season renovations; particularly important if you have been affected by flooding
- You could also consider booking in your machinery for its annual service/repair, ensuring you get the time slot that suits you
- Dragmat, harrow and groom rake surface, as required, to maintain levels, remove early morning dew, control disease and generally get air in and around the plant
- Spike/verticut as often as possible
Remember – the more that club members, players and officials understand what you role involves, the better. You could use any spare time to provide a members newsletter/blog detailing what problems you are experiencing (training regimes, waterlogging etc.) and to seek additional help as required.
Weekly checks:
- Check goals for loose bolts and tighten as necessary
- Check team dugouts are stable and anchored securely. Make sure that they are tidy and free from litter
- Repair and maintain fence lines
- Sweep up/vacuum fallen leaves
Renovations
Renovations should be in the forefront of your mind. Bear in mind any problems that you may have encountered during the season ("wet-spots" or poor drainage). Try to solve these problems during or before renovations start. You should, by now, have quotations for your renovation work and a provisional starting date with the contractor, or booked the machinery with your local ground care hire shop.
The type of end of season renovation will be dictated by the condition of your pitches, however, the extent and what you can achieve will be driven by cost and the will of the club to invest in their pitches.
A typical end of season renovation will be centred around aeration (decompaction), scarification to remove thatch, open up the sward, topdress to restore levels and overseed to introduce some new grasses.
Before starting any remedial work, it is vital to know how much you will need to spend on renovation, as cost can easily escalate if you fail to research prices against the standard of surface you wish to produce. From a commercial point, the cost of renovating a football pitch can range from £4k -£40k The higher costs often relate to more intensified specialist work being required such as fraise mowing and the cost of top dressing materials being used.
The application of the topdressing as the material alone can cost anything from £35 per tonne, this work alone is the most costly part of pitch renovation and, based on an application of 100 tonnes, can easily run out at three to four thousand pounds for a 6,000m2 pitch. With various options to choose from, you may decide on a high end budget if finances allow, but, at grass roots level where every penny counts, it is more likely that a low expenditure option is chosen, with much of the work done in house with borrowed or hired equipment.
It is this cost that deters most clubs from spending money on top dressings for their pitches, which is why there are so many poor sports pitches across the country. Top dressing is an important and integral part of maintaining good football and rugby pitches by restoring levels and improving surface drainage.
Whilst we have established that maintaining a rugby pitch is an all year round activity, we do have to start somewhere, so where better than at the end of a very long playing season, usually at the end of April.
The condition of your pitch will dictate what work will be required; most pitches will have lost between 50-75% grass cover during the playing season coupled with the fact that the soil profile will have become compacted. To rectify these problems, it is essential that a programme of deep aeration (100-300mm deep) is carried out, followed by fertilising, overseeding and topdressing which will help restore levels, feed and re-introduce some new grasses into the playing surface.
However you achieve it, you will need to clean out the surface and get rid of the dead organic matter that will have built up, particularly on the wings of the pitch, and the remnants of old divots etc. A tractor drawn rake followed by a box mower is probably the most traditional method and most likely within the means of most clubs and schools. You may also have use of a pick up flail mower, in which case you may find that scarifying tines can be fitted and the job will be completed in one operation.
This method can be advantageous as the scarifying tines may leave a grooved surface, ideal for ensuring oversown grass seed is buried just beneath the surface and in contact with the soil.
An operation that is becoming popular to those that can afford it (mostly Premiership clubs fall into this bracket), fraise mowing is extremely efficient at removing the top organic layer of the pitch, however, you will effectively be starting again with a newly sown surface, so your seeding rates will need to be higher.
Raising/restoring surface levels and getting rid of those compacted areas in front of the goal is everyone's obvious, but don't forget the linesman's run-up; sometimes forgotten, but easily incorporated into your programme and, whilst you're about it, the area beside the pitch that everyone stands to watch the game will need attention.
Spiking to relieve compaction and getting air back into the soil is important. If you have a spiker that will allow some heave, such as a vertidrain or Weidenmann etc., you may find this beneficial, otherwise you may do well to hire one in or employ the services of a local sports ground contractor.
Get a good quality grass seed for your renovation, and also fresh seed is important as old seed will not germinate as greatly or as well as new. Ensure that you achieve good seed to soil contact slightly below the surface, as seed lying on the surface will not germinate as well as seed that has been worked into the surface.
There are a number of ways to achieve this, by means of tractor mounted or pedestrian dimple/sarrel roller based seeders or disc seeders. Other ways to achieve this would be through surface spiking the area, brushing and then topdressing.
Topdressing - get it ordered and ready. Choose wisely for compatibility with your current rootzone. If you employ the services of an agronomist, then he will advise you of the best topdressing for your situation. If you cannot afford to topdress, you may consider hollow coring, recycling them by breaking them up and dragmatting them back into the surface.
Raising/restoring surface levels and getting rid of those compacted areas in front of the goal is everyone's obvious, but don't forget the linesman's run-up; sometimes forgotten, but easily incorporated into your programme and, whilst you're about it, the area beside the pitch that everyone stands to watch the game will need attention.
A good pre-seeding fertiliser, low in nitrogen and high in phosphate and potash (P:K), to provide the young seedling with the essential nutrients that will be deficient in a soil washed through by winter rains.
Turf treatments - some turf treatments work well for some and there are a number of them to choose from, such as organic based micronutrients, seaweed treatments, clay flocculants, amino acids and plant growth regulators such as Primo Maxx. It can sometimes be difficult to assess the benefits of such treatments, but most managers will notice if it has been effective or not. If you are unsure, then ask you supplier for a trial amount and test it for yourself. I'm sure they would be pleased to accommodate you.
A planned programme of work involves mostly renovation, which is the repair and restoration of the playing surface back to its original state, condition or, improved upon in order to be used again.
Timing is the key to success as many operations will fail and cause more problems than benefits when carried out at the wrong time of the year. In order to achieve this all operations need to be carried out in the right methods, having the right soil & weather conditions, the ability to time the schedule of work and in the right sequence.
The main objectives of renovation which should be considered are:
1. To maintain the standard of the surface.
2. To improve the standard of the playing area.
3. Rectify and install any new drainage requirements.
Once we have removed the posts, we can proceed to reduce the amount of grass from the surface to about 10 –15mm, preferably boxing off all arising’s at this stage.
Totally scarify the surface to remove all debris, thatch and organic matter. A number of passes may be required at different depths depending on the amount of organic material that is to be removed.
All arisings should be removed from the surface before the next stage of work is started. By creating a seed bed through scarifying, overseed the playing area with a 100% Perennial rye grass (preferably with three or more cultivars) by use of machine (auto seeder) bury the seed in about 10-12mm deep to ensure good seed to soil contact.
Topdress the whole pitch with a sandy/soil rootzone of 70/30 to address your levels. Aeration can then be performed to de-compact the surface allowing the top dressing to migrate down the tine holes to help with draining the surface and improve the soil profile. Drag matting or brushing will assist in this operation. An application of a pre-seed fertiliser to speed up germination or a spring/ summer 9-7-7 could be used. A soil test should determine you N.P.K, if in doubt.
Ensure bare areas are well irrigated to establish early germination. Allow new grasses to grow to at least 2nd or third leaf stage before mowing with a sharp rotary, as a cylinder mower will most likely tear the grasses from their roots. Mow and aerate regularly throughout the summer and where possible Verti- cut to help thin and prune the sward through this period. Spray for control of pests, weed and disease and over the coming weeks your sward will thicken up and become denser providing a perfect carpet for the forthcoming season.




I started last month’s diary looking towards the weather hopefully starting to improve by the end of February, and thankfully it has. However, that doesn’t mean we can ignore the poor weather that has been before. The cold continued from the end of January and well into February with more freezing temperatures and snow cover, meaning prolonged issues for turf managers. Fortunately, the temperatures started to rise at the back end, and it felt like the ‘false spring’ had arrived. This has allowed many turf mangers to get some much-needed work carried out on surfaces. Although not the typical time to carry out ‘extensive’ work, there are many examples of success with utilising this method. There are undoubtedly though, also some examples of this being unsuccessful and highlights the point that everyone has different circumstances and we must try and do what is best for our turf on our site.
March’s forecast looks unsettled, which is typical for this time of year. The start of the month, moving towards the middle, looks fairly settled with sunshine and showers, combined with favourable daytime temperatures, which should be encouraging for early season growth and recovery. The predicted night-time lows will restrict any great increases in growth potential and therefore fertiliser applications should be made with this in mind, with caution at making unnecessary applications of excessive nitrogen. Then towards the back end of the month it is forecast to be unsettled with multiple days of rainfall predicted. This coincides nicely (not) with the upcoming commencement of outdoor sports, following the government’s latest COVID-19 lockdown restrictions update, allowing organised adult’s and children’s sport to take place from the 29th March, which will be welcomed by us all I’m sure.
Although I can imagine everyone is desperate to get back to doing the things they most enjoy, such as participating in sport, the date given allows turf managers some time to prepare for the return of sporting activities. The plant will have been under considerable stress, given that the ground in many locations has been saturated for some time and has undergone periods of snow and frozen ground. With the return to play approaching, many will look to carry out maintenance work that would typically be done later in spring, with a view to minimise any disruption; here the key is striking the balance to ensure there will be adequate recovery from the work carried out in time for when play returns. If this isn’t likely, then planning the work when conditions will be more favourable, with decent soil temperatures and more daylight hours, is a reasonable approach.
Selecting the ‘right’ fertiliser at this time of year is critical to ensure that the turf is encouraged to recover from the stresses of the winter, without unnecessarily trying to force growth that just isn’t realistic if the environmental conditions aren’t advantageous. This will give the turf a gentle wake up and help ensure optimal turf health moving through spring. The type of Nitrogen source(s) within the fertiliser will play a major role in this selection;
Nitrate
The nitrogen available from potassium nitrate or calcium ammonium nitrate, for example, is freely available for plants to take up, and for this reason it can be useful where rapid or immediate growth is required. This also makes it particularly useful in the winter and early spring where its availability can stimulate growth under colder conditions. Nitrate is highly mobile and will reach plant roots quickly providing an almost instant nutrient supply.
Ammonium
The ammonium form of nitrogen is typically used in the amenity industry as ammonium sulphate, also called diammonium sulphate or sulphuric acid diammonium salt. Fertilisers containing nitrogen in the ammonium form provide a readily available form of nitrogen and this also makes it particularly good in cool conditions with average to low growth potential, as grass will utilise nitrogen in both the ammonium and nitrate forms, its ability to fix to soil minerals makes it less mobile than nitrate. In warmer conditions, microbes will rapidly begin to convert ammonium to nitrate in the process of nitrification.
Urea
After application, urea first needs to be broken down by naturally occurring enzymes called urease to ammonium before it can be utilised effectively by the grass. As this process occurs rapidly in warmer temperatures, the grass is provided with an easily available source of nitrogen, although it becomes more limited during the colder winter months when growth potential is lower. The ease at which urea becomes soluble also makes it both an ideal liquid fertiliser and granular product. However, during the process of transformation, during the warmer temperatures of the summer months, urea can be prone to volatilization losses and this can make it less efficient than stabilised forms of this nitrogen source.
Urea Formaldehyde (Methylene Urea)
This is an example of a long release source of urea nitrogen fertilizer. Urea formaldehyde’s rate of decomposition into carbon dioxide (CO2) and ammonia gas (NH3) is determined by the action of microbes found naturally in most soils. The activity of these microbes, and therefore, the rate of nitrogen release, is temperature dependent. The optimum temperature for microbe activity is approximately 70-90 °F (approximately 20-30 °C) making this an ideal choice during high levels of growth potential.
Organic
An organic fertiliser is composed of natural materials derived from animals and plants, but they may also be from mined minerals e.g. rock phosphate. Relying on natural biological and chemical processes, nutrient content tends to be lower, less exacting and released much slower than conventional fertiliser products. However, many amenity fertilisers are also a blend of inorganic and organic forms and provide a broader range of benefits with regards to nutrient availability and soil microbiology.
Applications of biostimulants will be beneficial to the plant and soil as the rate of photosynthesis starts to increase, so will the requirement of energy from the plant. Therefore, applications of carbon in the form of simple and complex sugars can act as an energy supply for the plant and help reduce any stress from any maintenance works carried out. As the soil becomes more active with temperatures increasing, the carbon will act as a food source for the soil microbes and increase soil activity. Poa annua seed head development can start early and this is also a big consumer of the plant’s energy. Applying a plant growth regulator early to suppress the development of seed heads can help re-direct this energy away from seed head production into other plant development processes.
As we head into March, we move ever closer to hearing the synonymous ‘buzz’ of summer from the humble bumble bee. But as more and more species are becoming extinct or highly endangered, will this sound always be around in the future? There are numerous campaigns running nationwide to ensure the future of the bumble bee. Remember, one in three mouthfuls rely on pollinators, therefore if we can encourage the environments which they thrive in, we can help protect their and our futures. Spring is the perfect time to sow a wildflower mix and they can really transform areas into a bio-diversity haven that is also great to look at and enjoy.
- Check and service any floodlighting systems.
- It also important to replace any worn tines on your aeration equipment.
- Clean out the shed, sell off any old machinery and dispose of any junk that’s clogging up the shed.
