Key Tasks for August
- Maintain sward height at 50mm-70mm for Football, 20-40mm for Hurling; the top height will cushion heavy falls on any hard ground.
- Mowing will increase as soil and air temperatures continue to stimulate grass growth
- Ensure that all areas are watered uniformly to promote healthy growth. Irrigation will be a priority, especially if maintaining newly sown or turfed areas. It is important to ensure that the water gets down into the rootzone to encourage deep rooting. Allowing areas to dry out can lead to problems of dry patch, a condition that prevents water infiltration into the soil, thus forming areas of non-uniform turf quality.
- Linear aerators now offer alternative methods of aeration to the traditional solid tine spiker and hollow core spiker, which can install a continuous slit 10mm wide 200mm deep at 200mm centres. The machine has also been upgraded to infill with kiln dried sand
- Brush to remove dew and remove surface debris. Using a brush will restore levels and produce striping or banding aesthetics
- Pre-season training will be well underway, with club coaches demanding marked out areas for practices. Ensure you have enough marking materials and an efficient, quality line marker for carrying out these tasks
- Check with your relevant governing body for any amendments to the laws and markings of the pitch
- 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
The following points are essential requirements to help achieve accurate linemarking:
- A reliable, accurate linemarking machine
- Appropriate, approved marking fluid
- Careful planning and preparation (setting out lines)
Pre match inspections:
Pitch surface, linemarkings and posts.
Keep heavy wear areas roped off to stop unwanted early use.
Tidy up the edges of the pitch, strim around advertising signs and crowd barriers. Presentation on the pitch will be let down badly by unkempt edges.
GAA Artificial Pitch Maintenance
- Keep surface clean
- Brush according to manufacturers recommendations usually after every 7 to 10 hours of use or once per week and no more than 3 times per week general rule. Keep records.
- Remove any algae and moss from surface. Crumb Rubber filled systems require regular brushing to maintain manufacturer's recommendations on rubber levels and pile heights.
- Check line and seems for any glue failure or tears and repair immediately any seems left unrepaired can become a big problem quickly
- Check fencing around pitch for loose panels
- Make sure that goal mouth rubber levels especially along kick out areas and replace if low.
- Clean decontamination areas out, make sure brushes at entrance and pitch signage is in place.
- The carpet is usually contaminated with debris from pitch. Brush carpet when dry to remove any clay particles. Make sure levels are ok with clay surrounds.
- It's a good time to raise goal mouths if the pile height of the carpet is below the bordering natural pitch. Remember raising the carpet means raising the cross bar.
Entering August signals the start of late summer, and with it shorter days and cooler nights than the long days of June and warm sticky nights of July.
August regularly offers periods of heavy rainfall and storms. Generally, conditions for growth are good during August but, as ever, it is extremes which challenge the grass plant and the turf manager in equal measure.
Strategic application of nutrition aimed at providing the grass plant with the means to maintain consistent health are as important as ever.
Calcium is a key nutrient to regulate water use efficiency, as well as increase tolerance to biotic and abiotic stress via thickening of the plant cell wall.
Towards the end of the month, dews will become heavier potentially providing conditions for Microdochium patch; at the start of the month, the risk of high temperatures combining with high humidity will promote disease such as Rhizoctonia. High temperatures during July’s hot periods will have activated Anthracnose. Other diseases such as Take-all patch and Waitea patch and Dollar spot may occur.
The key here is to understand the environmental and cultural triggers, and then employ nutritional and cultural strategies to counteract the risks. Increasingly, with the withdrawal of chemical fungicides the turf manager is responsible for seeking out the knowledge to understand the drivers of each disease and then employ multiple tactics to combat the risk. For example; Take-all patch attacks the base of the plant and root system, acidification in the rhizosphere helps to combat this; something which can be achieved via the regular application of Manganese. Anthracnose; it’s a saprophyte, which means once triggered by hot temperatures it lies in wait for senescent (dying) plant material to trigger its attack into full blow foliar blight. Avoiding the stress, mitigates the pathogens ability to pounce. Therefore, adequate moisture, consistent appropriate nitrogen levels and the avoidance of other diseases (Anthracnose often occurs as a secondary infection) will help to keep it at bay.
Pests and Diseases
Effective integrated pest management necessitates monitoring of local target pest populations as a precursor for taking action. Chafer beetle lures set out in May will have given an indication of hot spots for adult activity. Lifting back turf in zones identified to be high risk for grubs allows turf managers to eyeball larvae and take action. The same can be said of leatherjackets, simply sheeting the surface with a 1m2 sheet of plastic overnight may encourage larvae to rise to the surface. Knowing what your high risk areas are, and then identifying the level of pest incidence, allows for targeted treatment with Entomopathogenic nematodes. This biological control requires warmth and moisture in the soil to be most effective. Targeting this year’s larvae when they are small and susceptible gives your army of microscopic worms an increased chance of success. With chafer and crane fly larvae hatching out in August and September, these are the key months to gain preventative control and prevent problems in spring and early summer 2020.
Preparation for end of season renovations should be in full force; the prime aim being to manage organic matter accumulation and promote recovery of the grass plant in time for autumn and winter. Biostimulants, such as liquid Seaweed and humic acids, will promote seed germination and establishment in combination with the usual fertilisers.
Start of Season
As some sports engage in renovations, winter sports start their playing season. Maximising pitch quality through late summer and early autumn is critical to keeping you ahead of the curve when things turn against the grass plant in the winter. A good quality slow release NPK feed now will keep things moving in the right direction over the next few months. It will also help to showcase surfaces at their best as the first matches of the season begin.
At this time of the year, it is important that mower blades are clean and sharp. Blunt blades will tear the grass and leave it susceptible to disease.
Keep machines overhauled and clean. Ensure you look after your equipment and store safe and secure, it is a good idea to get into a habit of washing down and and cleaning after use.
During this month: Please ensure that all goalposts meet health and safety standards.
It would be prudent to thoroughly clean out your linemarking kit. If the forecasted showers appear, what better time to do this mundane but important job? Regardless of the type of machine you use, you'll be pleasantly surprised by how much better your lines will look for the start of the season.
Other areas should also be checked over, such as fences and dugouts.
