Key Tasks for April
As normal for this time of the year, squares will require a lot of time management, scarifying, mowing, rolling and marking out; then there is your outfield, which will require mowing, aeration, raking or harrowing to raise the sward.
It is not necessarily about how much Pre-Season Rolling you carry out, it is ensuring that the rolling is undertaken during optimum conditions by having enough moisture in the soil profile to allow for good consolidation.
Ensure your machinery and equipment is serviced, in good condition and ready for use.
Pitch preparation should start 10-12 days prior to the match. Following the guidelines below will help you achieve a good standard of pitch. Most groundsmen will have there own interpretation of these activities. Marking out the crease should be done with care, using frames or string to help achieve clear, straight lines. DAY 1 String out pitch lines to ensure correct width, 10 ft; Mow out @ 8mm. Always double mow (up and down the same line), using an 8 bladed pedestrian cylinder mower for maintaining the square. Test the pitch with a key or knife for moisture
DAY 2 Brush / light rake, mow @ 8 mm, light roll to consolidate surface levels.
DAY 3 Scarify or Verti cut to remove lateral growth and surface thatch avoiding deep surface disturbance. Reduce HOC & mow @ 7 mm. continue medium light rolling 1000 kg 10-15 minutes.
DAY 4 Roll pitches increasing roller weight to consolidate the surface.
DAY 5 Scarify with hand rake to raise sword after rolling. Reduce HOC to 6mm
DAY 6 20-30 minute’s with heavy roller.
DAY 7 Light scarify by hand to raise sward, mow @ 6 mm, increase weight of roller to 1500- 1700 kg continue rolling 30 minutes reducing speed to consolidate surface.
DAY 8 Continue rolling for 30 minutes at slow speed to achieve consolidation. Cover pitch over night to encourage moisture to rise to surface.
DAY 9 Brush / rake lifting any lateral grasses, reduce HOC mow (with a shaver blade) to 4mm, try to avoid scalping. Roll using heavy roller slow speed (crawling) 30 minutes morning & again late afternoon where possible. Cover pitch over night.
DAY 10 Brush & mow pitch, roll morning and afternoon slow as possible (crawling).
DAY 11 Brush, mow & roll to polish surface, test bounce with an old ball along edge of pitch. Continue rolling to consolidate surface. Cover pitch over night.
DAY 12 Brush, mow & roll polish up pitch. Your pitch should effectively have take on a straw like coloration, a sign that the preparation has been achieved. String and mark out as in accordance to E.C.B guidelines. (TS4 booklet)
Mowing heights for the cricket square during the playing season should be:-
8-12mm April-September (playing season)
5-6mm Wicket preparation
3-4mm Final cut for match
Soil and air temperatures should begin to rise substantially as we move into April. The application of a spring and summer fertiliser will also increase the vigor, sward growth and density. Ideally, get your soils sampled for nutrients, organic matter content and soil pH where possible. This information will help decide on the appropriate course of action with regard to applying the correct NPK balance for your site. Liquid fertilisers are becoming popular again.
Granular products have to rely on the granule breaking down, becoming mobile in the soil and then taken into the plant via the root system. Today’s products have been refined to act more efficiently, their mode of action allows the active nutrient ingredients to get into the plant tissue more quickly, and thus you tend to see a faster response to plant growth Wetting agents can now be applied; this is usually done on a monthly basis. The use of wetting agents will be a good tool for ensuring that any rain has the chance to soak deeper into the soil profile and not simply run off the playing surface.
Structures: Check and repair fences, scoreboards, covers and sightscreens. Finish off any painting that may have been delayed due to bad weather.
Artificial Pitches: Keep all surfaces clean, by regular sweeping and brushing to remove any algae and moss from surface. Sand filled systems also require regular brushing to maintain manufacturer's recommendations for sand levels and pile heights.
Other work to consider:-
- Mark out boundary line or ensure rope is in place.
- Scoreboards are ready for use
- Erect security netting around buildings to deter balls from damaging properties.
- Ensure stumps and bails are correct size, yardage disks are available.
- Check sightscreens, covers and machinery as breakdowns could be time costly.
- Artificial netting facilities should be checked, cleaned and marked out ready for use.
Adequate temperature, light and water are the key drivers of plant growth. Whilst the sun continues to rise on a daily basis, light of one intensity or another remains available consistently. At any time of the year, and particularly during April when there tends to be disparity between day time highs and night time low temperatures, accompanied by dry periods without rainfall, often the trend these days, over and above the ‘April showers’ of yesteryear, adequate temperature and water are the two factors which determine grass growth. As always, the key to success is looking ahead and factoring in strategies to keep in front of the curve whilst, at the same time, reflecting back as to what lessons can be learned.
On winter sports pitches, maximising spring recovery growth from the winter with good quality sports turf fertilisers increases the sward density ahead of the end of season. This is something which potentially allows for a reduction in the volume of overseeding requirement during renovations. For amateur clubs, this is a key consideration, especially given the reduced seed harvest yield in 2018 as a consequence of the long dry summer; a factor which was compounded by high demand across droughted areas, necessitating manufacturers to dip into stores of the 2018 crop in the autumn of the same year; a course of action required by turf managers needing to repair dead patches before the winter.
Here we sit then in spring 2019, with reduced availability of seed and increased demand as turf managers again dip into the depleted 2018 harvest to tackle areas which did not recover adequately. The outcome of this situation in the supply chain is increased demand, clashing with decreased availability. The consequence is less choice and increased price.
The reason I raise this is for awareness. It is important that turf managers are aware of such a situation and how it came to be. The situation is of course a consequence; a consequence of an extreme weather pattern, and one which is predicted to increase in probability over the coming years.
The key consideration then for turf managers is how does this potentially affect my club and what can I learn for the future? In the case of availability for the 2018 seed harvest throughout the 2019 growing season, it may well be:
- You can’t get exactly what you want.
- You can’t get it when you want it.
- It will cost more.
The contemplative questions for the turf manager are;
- How will that affect my maintenance timings?
- How will that affect playing surface quality?
- How will that affect my budget?
The overriding point here is; greater unpredictability of the climate leads to more uncertainty in respect of what we can do, when we can do it and for how much money.
Anyone who wishes to ride the ups and downs of these unpredictabilities in a smoother fashion, with less buffeting and a more consistent product for players, will be an individual who factors in flexibility of their approach with respect to planning maintenance operations, and is able to communicate that requirement effectively to their members, players and wider stakeholders.
For example; dry soils in October and November 2018 would have benefited enormously from applications of penetrant wetting agents in a bid to capture as much available rain all as possible and channel it down into the soil profile. It is then positioned to act as a reservoir for 2019. Areas which are still dry only a few inches below the surface will burn off much faster than in 2019 than they did in 2018. In turn, lower water resource in the soil means that plant stress will be encountered with less cumulative dry days, and likely sooner in the year than in 2018 when water was in good supply. As a result, implementing block-copolymer wetting agent programmes and checking irrigation efficiency this April are actions more important than ever.
These examples of consequence from extreme climate is of course something which is not sport specific, golf fairways, tees and surrounds, football pitches, bowling greens and cricket outfields are all effected equally alongside grassed amenity spaces. Would a penetrant wetting agent, at relatively low cost per hectare, applied in autumn 2018 have gone some way to help mitigate a potential problem in 2019?
Another example which is prevalent on many areas where grass died and did not recover well in the autumn is weeds and moss recolonising these areas faster than the grass plants. This may well require such areas to be sprayed with a selective herbicide as we get towards the end of April and into May. Is this something which has been budgeted for? If it is not undertaken, what are the consequences for consistent turf quality moving forward?
In areas which had suffered from the 2018 drought, one should be mindful that not all grass is equal. I was stood on a bowling green with a gentleman only two weeks ago, who happily proclaimed that even though the green had been rendered completely brown in summer 2018, it was fine now that a coverage of grass was infilling the worst of the extensive bare patches.
A discerning eye revealed the grass growing in these areas to be almost entirely poa annua; a weak, shallow rooted annual species evolved in the wild to rapidly colonise shallow soils, flower and then shed the seed of the next generation as quickly as possible. A trait evolved in preparation of the weather turning dry over the summer, quickly forcing it to enter dormancy then death. The truth on the green in question was that whilst grass is returning, it is not a grass which will provide a sustainable and good quality playing surface once water and warmth are not at optimum levels. Unlike perennial grass species, poa annua will be the first species to cause a problem by checking out once the going gets tough.
The overriding message from these examples is intended to be; don’t rely on what worked last year to suffice this year - always be looking ahead, by asking questions and seeking answers for how to deal with what lies around the corner.
Maintaining a cricket square requires regular mowing, so it is important to keep your blades sharp at all times. Backlapping will help prolong their lives, but they should be sent for re-grinding, with your bottom blade replaced at the same time, especially a shaver blade.
Check your ground for foreign objects, such as studs or stones which can cause considerable damage to machinery and pitch.
