Liner upgrade solves problems at CordeValle

Liner upgrade solves problems at CordeValle: Designed by the Robert Trent Jones II firm (and actually the firm’s home course), CordeValle GC in California’s Santa Clara Valley, has some of the largest and most imposing bunkers to be found anywhere in golf.

There may be only 63 bunkers on the golf course, but the total area of sand is a breathtaking 188,000 square feet (17,500 square metres). And, according to superintendent Brett Thornsbury, the playing consistency of the bunkers was becoming his biggest challenge..

“We have large, very elaborate bunkers with steep faces,” he said. “Over the years, as with all aging bunker sand, it had lost its original color, the consistency to move water, and the playability was negatively affected, especially during the dry summer months or excessive rain events. With this project, we wanted to restore the sand to its original color, ensure the health of the drainage system, and most importantly, install a bunker liner that was going to last for many years to come.”

CordeValle’s bunkers were originally lined with a geotextile, but its performance had deteriorated since the course’s opening in 1999. When Thornsbury became superintendent four years ago, he quickly realized the bunkers would need to be addressed in the near future to maintain a high-quality of playability and consistency.

In 2019, led by RTJII president Bruce Charlton, the course’s greens and approaches were renovated and regrassed.. The completion of this project left the bunkers as the next major issue to be improved , and last year, Thornsbury was able to start the work.

“We knew the bunkers needed to be relined, and we wanted a liner that could perform at the highest level, no matter the season. he said. “When we researched the options, it became clear to us that Capillary Concrete had a superior bunker product, and was the one we wanted to use.”

The bunker project began early in October of 2020, and was completed in the middle of March 2021. “We tried to have the lowest possible impact on play, using temporary greens where necessary, and always keeping eighteen holes open,” said Thornsbury. “Fortunately for us, we had a pretty dry winter allowing the project to work mostly uninterrupted. However just a few weeks ago we had our first major rain event of the season, producing six inches of rain in less than three days, which for us in Central California, is welcomed and unusual. Not one speck of sand moved in our newly completed bunkers. The team was relieved to see they didn’t require any repairs after such a heavy rain event and kept the sand shovels in the shop that morning. It’s a testimony to the Capillary Bunkers product.”

ICL the ‘one stop-shop’ for Bradford City

ICL the ‘one stop-shop’ for Bradford City: ICL’s ProSelect grass seed supported by a monthly nutritional programme has resulted in Bradford City’s pitch being in the best condition ever – according to Head Groundsman Mick Doyle.

If anyone knows the pitch at Bradford City’s Utilita Energy Stadium – it is Mick. He has been working at the club for an incredible fourteen years and in that time, it is safe to say that he has single-handedly kept the pitch in excellent condition.

However, he claims that the bar has now been raised and that it all started with ICL’s ProSelect grass seed.

“The bottom line is that I needed a new seed,” he said. “The seed I used previously just didn’t work for me – it was patchy and did not germinate. Therefore, when it came round to pitch renovations last year, I used ICL’s ProSelect 1 Premium Pitch which I had first heard about at an ICL educational day and after speaking to other groundsmen.”

Combining four top-ranked perennial ryegrasses, ProSelect 1 Premium Pitch, provides a fast-recovering, dense, hard-wearing surface. Furthermore, Mick decided that he would like to explore a full ICL nutritional programme because in his words, it would be a “one-stop shop which could deliver on all fronts.”

Prior to sowing the ProSelect seed, Craig Lalley, Technical Sales Manager for ICL visited Mick at the stadium and took some soil samples. Craig then proceeded to devise a plan tailored to Mick’s environment – taking into consideration his stadium, his machinery, his staffing levels, his time restraints and he ultimately put a programme together based on what Mick was trying to achieve.

“My biggest concern was that I could never get any root down but Craig assured me that I would with his programme,” said Mick. “True to his word – he was absolutely right.”

The key was getting the pitch off to the best possible start. After sowing the ProSelect grass seed, Mick immediately followed with 10 litres of H2Pro TriSmart, in a bid to absorb more moisture around the seed and aid germination.

It turned out to be a winning combination: “The seed was coming up beautifully in just six days,” said Mick.

On that sixth day after seeding, and based on Craig’s advice, Mick went one step further by applying Sierrablen Plus Renovator 20-20-8 at a rate of 35g/m², the mini-granules ensuring even distribution for young seedlings while its high phosphate levels encourage strong root growth.

Since then, the nutritional programme has been based on providing the right nutrient at the right time, according to Craig.

“A lot of the programme has been designed to really focus on root establishment to assist with pitch playability. Therefore, Mick has been using Vitalnova SeaMax (seaweed extracts) and Vitalnova Blade along with Primo Maxx II growth regulator.

“Mick has produced a great surface this season and that has carried through the challenging winter months. To work alongside his good cultural methods over this testing period, Mick incorporated H2Pro FlowSmart into his monthly ITM programme. This is a superb penetrant to help with water percolation through the profile.”

Mick was also in agreement:

“I’ve had fourteen seasons here and I can honestly say that this is the best condition the pitch has ever been at this time of year. I put that down to the products.

“The pitch is holding up incredibly well and you can hardly tell that players have been on the pitch after a game. In years gone by where we have had shallow rooting a lot of remedial work was needed following fixtures. This is no longer required so we are saving time and benefitting from good plant health.

“It’s just been consistently good all year.

“The programme is very straight forward to follow – it’s all on my wall planner in my office and reminds me of what’s going on at all times. I can also call Craig and get advice which is a real benefit.

“Overall, I’m incredibly pleased that I decided to go down the ICL route because it really has made such a difference to the pitch – not just aesthetically and from a playability point of view, but also from what is going on below the surface.”

Scatter seeds for a brighter year ahead

/in , /by

Scatter seeds for a brighter year ahead: Spring is traditionally seen as a time for renewal, growth, and new life, with warmer days urging us outdoors to enjoy nature. This year we have even more to look forward to, with reunions on the horizon and things returning to a semblance of normality.

With these brighter days and positive thoughts of the year ahead, now is a great time to get outside and scatter some wildflower seeds to ensure that 2021 and beyond is full of life and colour.

Wildflower specialist, Seedball, has developed a unique way in which to protect scattered seeds until they are ready to look after themselves, creating a mini ecosystem and giving them nutrition as they germinate and grow. The balls are made from a combination of British wildflower seeds, clay to protect from predators such as birds and ants, peat-free compost to provide nutrition, and a little bit of chilli powder to deter slugs and snails. Simply throw the balls onto soil or compost in a garden bed or planter in Spring or Autumn and wait. The seed ball has everything it needs to grow and, once the ball becomes moist and the temperature is right, the seeds will germinate! What could be easier?

While Seedball is famed for its compact tins of seeds that are ideal for gifting, the company also produces larger grab bags, each containing 100 seed balls, make it easy for everyone to create a wildflower patch in their own garden, and what could be a greater symbol of positivity and optimism than that? The range includes bags of curated seed collections, such as the Bee Mix and the Shade Mix, to help people create wildflower havens with ease.

New for 2021 is a collection of Single Flower Grab Bags, each of which contain 50 seed balls of a single variety, allowing even more flexibility for people to design their own outdoor spaces according to individual preferences. The 24 varieties include quintessentially British species such as cowslips, cornflowers, yarrow and camomile.

People will even be able to create their own delicate, blue carpet of bluebells with the Bluebell Grab Bag – provided they are willing to wait for them to flower, which can take up to five years after germination. These native flowers are more than worth the wait, though, and are one of Britain’s most precious and iconic plants. The variety available in the grab bags is the Hyacinthoides non-scripta, with a distinctive scent that is highly attractive to bees.

A simple scattering of seed balls today will result in a brighter, wilder tomorrow!
