Key Tasks for April

It's a difficult time for everybody, and our advice is to follow any guidance issued by the Government and the Sports Governing Body regarding the maintenance of your sports surfaces. In addition to the maintenance guidelines below, you will also find topical advice on the Pitchcare Forum on how to manage your surfaces should the Coronavirus restrictions be increased.

Your number one priority is to keep safe.

The emphasis at this time of the year will be on mowing frequency, as long as there is sufficient moisture within the soil.

Mowing. Greens should be mown at least three times a week, with some grooming, verti-cutting or brushing being undertaken on a weekly or twice weekly cycle to improve air movement and reduce thatch levels building up in the sward profile.

The sward will be actively growing due to the increased soil temperatures, coupled with the stimulation of fertiliser applications. Regular mowing will be required to maintain sward height at around 4-5mm. Verti-cutting/grooming fortnightly can be carried out to help speed up the green and help improve the health of your turf.

Aeration should continue, using a mix of micro, needle or star tines which give maximum effect and almost zero turf disturbance.

Regular use of a sarrel roller will be beneficial and the use of micro tines to aerate the green will help reduce soil compaction, 'vent' the root-zone and to allow water to move quickly from the surface and into the root-zone, thus encouraging the turf to root deeper.

Irrigation: Soil and air temperatures usually increase in April, often bringing on the need to irrigate. If soil profiles, particularly sandy soils, are allowed to dry out too much they often become water repellent (hydrophobic), a state when soils can become difficult to re-wet. Often the first areas to suffer on greens, particularly crown greens, are the high spots on the green. You may need to spend more time hand watering these problem areas.

When you do water, ensure you go to a depth of 100-150mm to encourage the roots to go down to find the water.

We face what is an unprecedented situation in modern times. Each and every corner of society at large is facing the reality of global pandemic at the hands of a microscopic infectious agent consisting of genetic material, in the form of long chains of DNA or RNA molecules. Viruses are somewhat indefinable; having been said to be “organisms on the edge of life”. As we all already knew, but are now understanding, whilst they are both incredibly small and incredibly simple, viruses are able to impact all avenues of human life and society on a gargantuan scale. Their simplicity is, of course, their greatest strength.

At a time when the whole of human society is facing its greatest viral adversary since the 1918-19 H1N1 influenza pandemic, the value of the sports turf industry and the dedicated people who work to facilitate a surface for play, will no longer be in an active position of contributing towards providing recreational sporting activity in people’s daily lives. The industry, both at a professional and amateur level, contributes great value to the recreational activities of society; activities which will be sorely missed by many, but perhaps this presents an opportunity for them to be appreciated anew once they return. There are many challenges to be faced in the coming weeks and months, both professionally and sadly personally too, but with each hardship also comes opportunity. In particular, awareness of the smaller things; the details we often overlook in our busy day to day activities and pressures. Time may also be there for thought, reflection and inventiveness. For it is in the quiet times where the greatest opportunities for inspiration and creativity lie. These will be the things which allow all of us to collectively rise from the hardships. Things will be different, but we have it in our control to be able to make things a better kind of different. I was speaking to a Head Greenkeeper of thirty-five years’ experience a few weeks ago. Just as the current situation started to take shape, he said to me; “one thing’s for sure, we’ll all learn a lot from this, each and everyone one of us.” He was right. Let’s make sure we all support each other as an industry to make those lessons count.

The impact of this should mean that we do not hide from a situation where sports turf professionals and amateur volunteers across the country are facing immediate tough challenges and stresses. Clubs of all sporting disciplines will be facing tough decisions, relating to business and people, with curtailed budgets due to wholesale drops in revenue, and reduced staffing due to efficiency savings and governmental advice. All these things are real, and all of them are tough. However, I know that one thing at the forefront of the mind of everyone involved in the day to day management and maintenance of a sports turf area will be the continued maintenance of the facility and the grass plant. For whilst human society grinds to a halt, nature in all its spring-like glory relentlessly endures without pause or consideration for human constructs. In the current situation however, we must be realistic about what we can achieve and we must, as with many aspects of our life, focus on the basics; the basics with respect to the grass plant are nutrition, light and water.

Key Agronomic Points

  • Grass plants not being subjected to play will be under reduced levels of abiotic stress. Without the need for play, we can reduce this further by increasing heights of cut. This will allow the plant to collect more energy, giving solar radiation and in turn create more carbon, both for itself and the beneficial microorganisms inhabiting the rhizosphere - as a result, we would expect plant health to be more resilient. Slow release spring fertilisers will provide cost effective nutrition in a steady flow, helping to regulate growth in a manner which promotes plant health but reduces pressure for maintenance.
  • Plant growth regulators, such as trinexapac-ethyl and prohexadione-calcium, will reduce growth pressure and may help to ease the mowing burden on stretched teams working reduced shifts or split days.
  • Water management will be assisted by sarrel tine aeration, which is time efficient, cost effective and allows a large surface area of the turf to respire gasses and percolate water. Surfactant programmes may still have a place for those seeking to reduce costs with water bills, should irrigation be required later in the year.
  • Pests such as leather jackets and chafer grubs will continue in their life cycles. So, whilst it may not seem the most pressing thing to pay attention to at this moment in time, maintaining observations as part of your Integrated Pest Management plan will be crucial for timing operations later in the season. The aim being to keep surfaces in the best condition possible later in the year, and at a time when maximising revenue streams may well be even more important than ever.

The coming weeks will be challenging, but if we do support each other as a sports turf community we can all help one another to the other side.
