Prevention is better than cure: As the weather warms up all potential water issues multiply, but there is a natural, environmentally-friendly, safe and cost-effective way to prevent problems before they occur with Otterbine’s range of surface and subsurface aerators.

Otterbine aerators have been successfully used as an algae control strategy to improve water clarity and quality the world over, simply by adding air and circulating oxygen in the water. This simple process stops the water from stagnating, keeps algae and aquatic weeds under control, eliminates odours, prolongs the life of the water and attracts wildlife.

The main difference between the two options of surface and sub surface aeration is where the aerator sits in the water: surface spray aerators, as the name suggests, sit on top of the water and throw water droplets through the air, while sub surface – or diffused air – aerators work by compressing oxygen and pumping it into the water from the bottom through specially manufactured air domes. Deciding which to go for depends on surface area, depth, quality of incoming water and available power.

Otterbine aerators are built to last, and limit the use of chemicals providing a tick to the sustainability box of every venue. They have some of the highest oxygen transfer and pumping rates in the industry – adding as much as 3.3lbs or 1.5kg of oxygen per horsepower hour into the water and pumping over 920GPM or 199m3/hr per horsepower – with independent testing from the University of Minnesota and GSEE proving it.

Robert Jackson, Division Manager for Reesink Hydro-Scapes, Otterbine’s UK distributor, says:  “Otterbine aeration systems are designed to be as close to a natural solution for water aeration as possible, protecting water clarity without using excessive amounts of chemical treatments. The aim is to keep water healthy and not leave things to chance, especially as the weather is generally warming up, not just as spring and summer approach.

“Rectifying problems is always more expensive and time consuming than preventing them and Otterbine aerators are straightforward and easy to install and last for years meaning they are the perfect long-term solution.”

In a world of ever-changing weather patterns, Otterbine provides an element of control. With a comprehensive range of quality products and warranties from three to five years, Otterbine presents a long-term water management solution to a significant potential problem with very little disruption or outlay.

Prevention is better than cure: There will be enough to do this summer with El Niño on its way, so don’t let water quality be another problem to deal with, especially when prevention is so much easier than cure, says Otterbine, a leading water management specialist.

Thanks to the warming effects of the climate phenomenon El Niño, when temperatures in the Pacific Ocean rise or fall beyond the norm and influence weather patterns across the globe, the UK can expect the summer of 2023 to exceed that of 2022 and turn out to be the fifth or sixth hottest on record.

And with the sun comes dangers for lakes and ponds. Left unattended, water can quickly deteriorate creating problems such as algae, aquatic weeds and odours, and while the repercussions are laborious and costly to fix, preventing them isn’t.

It all comes down to aeration, as Simon Powell, Otterbine business development manager at Reesink Hydro-Scapes explains: “Higher levels of sunlight and heat, generated by summer sun, can lead to excess nutrients in water bodies. When combined with low oxygen levels and limited circulation, the natural ecosystem tips out of balance, causing algae, weeds, odours and sludge to build up, which can even kill off aquatic life.

“Once a water body reaches this point the costs of trying to restore it increase dramatically. As well as often being more expensive to implement, reactive solutions tend to be less friendly to the environment too.”

The easy, sustainable solution is to add air with a surface and subsurface aerating system and Otterbine has some of the best in the business, confirms Simon: “Otterbine’s range of products has some of the highest oxygen transfer and pumping rates in the industry, adding as much as 3.3lbs or 1.5kg of oxygen per horsepower hour into the water and pumping over 920GPM or 199m3/hr per horsepower.”

With that kind of power and efficiency behind them, plus an average lifespan of 15 years, acting now in preparation for an El Niño summer means no more water worries whatever the weather for the foreseeable future.

Simon concludes: “In a world of ever-changing weather patterns, Otterbine provides an element of control. Being able to combine Otterbine’s range of quality products which are built to last and keep water clean, clear and healthy, with Reesink Hydro-Scapes’s warranties ranging from three to five years, means a water management solution that’s guaranteed to last, removing a significant potential problem from the to-do list for years to come.”

Prevention is better than cure: At a recent meeting of the Amenity Forum, Chris Faulkner of Kersten (UK) Limited spoke about the need for all involved in weed management in the sector to further increase the focus on weed prevention.

He said ‘’A common theme of the conversations we have with customers centre around removing, killing or controlling a weed that already exists. Prevention requires us to think about the causes of weeds on a particular surface and how we can make the environment as inhospitable for weeds as possible’’

In a recent presentation at a conference in Wales, the Independent Forum Chairman John Moverley, said ‘’prevention certainly on hard surfaces begins with the design of our environment. For example, designing the corner of a kerb with a nice wide radius, rather than a sharp corner allows a sweeper to easily follow the edge of the kerb and collect any detritus trapped there’’

Also at the conference, a representative from Newport Council commented about their success with improved preventative maintenance work. He said ‘’we have been using mechanical weed removal to minimise the soil build-up over winter and the team has seen a big reduction in the amount of weeds coming up in the spring. This has resulted in the diminished use of plant protection products around Newport’’

The amenity sector has been at the fore front of the development of integrated weed management and produces comprehensive guidance notes for the sector. It is important to recognise that integrated means choosing the right approach and choice of methods for weed management including plant protection products. The increased emphasis on moving to carbon zero also will significant impact on future approaches.

A new guidance note on weed prevention will shortly be available on the Amenity Forum website www.amenityforum.co.uk  and it will be just one of the topics to be addressed in Updating events across the UK organised by the Forum in early 2022. For more information contact admin@amenityforum.net

Drainage cure for Buckingham West End

/in , /by

Drainage cure for Buckingham West End: Buckingham West End Bowls Club was founded in 1910 and enjoys a strong and loyal membership. Situated in Buckingham itself, the club aims to promote the game of Flat Green Bowls and provide facilities for the social needs and well-being of its members.

As a mixed club, they play men’s, ladies and mixed matches with other clubs in Buckinghamshire, Bedfordshire and Northamptonshire. Greenkeeper Ian Jones joined the club in 2013 at which time, he says, the green drained well but in 2018 they started getting problems with drainage. On Christmas Eve 2020, the nearby river flooded the green to a depth of about 2ft. Although most of the water drained away within 24 hours, because of the drainage problem, part of the green remained underwater so long the roots of the grass began to rot.

“We use contractors Avonmore Associates to do spraying, aeration in autumn and top dressing and we worked with Avonmore’s Brian Buttler to take some core samples. While the topsoil was good, we found there was no drainage layer,” says Ian. Brian’s view was the constant walking on the green over the many years had caused severe compaction. They coupled this with another reason. The green sits on yellow clay, being near Bedford, which is famous for brick making using the clay over the past hundred years. Ian had seen an article on a South Wales bowling club that had a similar drainage problem and they had called in Terrain Aeration, whom Brian also knew of. Whereas normal aeration is an accepted part of a good greenkeeping regime, it only reaches a depth of inches.

Terrain Aeration’s system treats the ground down to a depth of one metre. At this depth, the ground is usually so compacted it requires fracturing to open up fissures and allow drainage. Their Terralift machine hammers a hollow probe through the soil using a JCB road breaker gun, and compressed air is released up to 20Bar (280psi). At the end of the air blast, they inject dried seaweed, which sticks to the fissure walls. This expands and contracts with the moisture in the soil to keep the area breathing. Ian and club member volunteers who help maintain the green backfilled the 1.5-inch probe holes with Lytag aggregate and covered with topsoil. The green was playable almost immediately.

“Had we put in field drains it would have been very disruptive and using Terrain Aeration’s system meant we could do the work in the season,” says Ian. “Then we had no rain for some weeks so we had no idea if it had worked until the heaven’s opened in June. After severe downpours, we found the green drained far better than in years and the club is overjoyed with the result.”

Prevention better than cure

Prevention better than cure: Ian Robson Prosport UK & Ireland Importer/Distributor for Foley United, explains why relief grinding maximises the performance of reels by giving a factory finish every time.

Firstly, why is having sharp cylinders (reels) that are the correct shape so important anyway? The answer is obvious – unhealthy turf brings a whole host of other issues which are costly to correct. Therefore, prevention is a far more economic approach than a cure.

Prevention better than cure

A huge amount of research and development has gone into designing a cutting unit to produce the cleanest cut possible with the least amount of fraying and tissue damage to the plant.

The result is that all manufacturers of grass cutting equipment supply new units with relief ground edges.

Why Relief Grind?

Tests carried out by leading manufacturers have established that relief ground cylinders stay on cut up to three times longer than spun ground ones and require less horse power to drive the unit, resulting in greater fuel efficiency and less stress on the hydraulic power systems. In addition, a relief ground cylinder will withstand the abrasive effects of top dressing far better than one spun ground because the relief edge on both the bedknife and the cylinder allows the top dressing to clear the cutting blades easily, helping to prevent the dulling effect seen on spun only units.

Continual relief grinding also decreases the squeezing and tearing of the grass as the units get dull, and most importantly it allows the cylinder to be returned to a factory specification perfect cylinder as quickly as possible.

The overall cleaner cut achieved by relief grinding gives a better after-cut appearance, increased recovery rate due to the clean cut of the grass and reduces the stress on components because less horsepower is needed to drive the cylinder.

Horse Power Study

As a reel wears flat and loses shape (becomes coned), more stress and strain is put on the cutting systems.

Using the figures from the above study a 5-gang cutting unit with relief can require up to 4.5 HP (5 x 0.88HP = 4.5HP) to drive the cutting units therefore a 35HP engine has 30.5HP remaining to drive the rest of the traction system. A 5-gang unit which has been spun ground only, can require up to 13Hp (5 x 2.59HP = 13HP) leaving only 22HP to drive the rest of the traction system.

So, it has been established that relief grinding your cutting units saves you money not only by reducing workshop maintenance time with far fewer grinds but also through a reduction in fuel costs and replacement parts.

It is also important to acknowledge what relief grinding does for a reel. By removing metal from the trailing edge of the blade it forms a relief angle, which reduces the contact area of the cutting edges, resulting in less friction, longer wear life. Typically, when a new mower is delivered the reels will be a perfect cylindrical shape. Over time the blade naturally loses shape, and the sharp edge it arrives with becomes flat and dull, often meaning the reel is no longer a perfect cylinder from end to end. This is referred to as ‘coning’ and a natural point for grinding to take place.

The decision then sits between touch-up and spin grinding, or relief grinding. If there is sufficient relief still on the reel then a quick touch-up is fine but once more than 50% of the relief has gone my advice would be to relief grind again and remove any coning. Failure to remove the coning will eventually be seen in an uneven cut appearance of your turf.

But, the main question mentioned at the beginning comes back; how to get the most out of your workshop resources by choosing the most effective method to sharpen your cutting units. The answer is to trust the manufacturers judgement and return the reels as close to the original factory standard as possible, and for that, relief grinding is the best option. The bonus is this method also maximises performance and gives the best cut.
