Independent research underlines credentials of younger thinner cut turf for quicker establishment to produce healthier better lawns

Independent research by the Sports Turf Research Institute (STRI) has underlined the credentials of younger thinner cut turf for its ability to root more quickly and vigorously than the traditional older thicker cut product, allowing faster establishment and a healthier and more attractive lawn.

The research comprised of two trials conducted at the STRI headquarters in Bingley, West Yorkshire, in Autumn 2017. The outdoor field trial saw the laying of both younger thinner cut Rolawn Medallion turf and older thicker cut Medallion turf side by side for 50 days. After just 20 days the younger thinner cut turf showed deeper, denser and more vigorous rooting compared to the older cut turf. Surface appearance was also better throughout the trial, with its NDVI (Normalised Difference Vegetation Index) score – a measure of turf health and quality – consistently higher throughout the 50 days of being laid.

STRI Research Manager Dr Tom Young commented “initial visual appearance of the younger thinner turf was superior to the older turf, with this effect lasting at least 20 days after laying. Furthermore, in the outdoor trial rooting in the younger turf plots was more vigorous and dense compared to the older turf”.

The second trial went on to further confirm the notion of quicker, denser root growth for younger thinner cut turf. Samples of both were put side by side in the STRI’s rhizotron, a controlled environmental chamber, to view root growth over time under LED lights. Almost immediately the younger thinner cut turf rooted more quickly and densely and continued to do so consistently throughout the two-week trial.

The unanimous findings of both STRI trials are also reinforced by several pieces of research going back as far as the sixties, which showed that younger thinner turf displays better rooting capabilities, and that young roots are more likely to regrow after harvesting.

As the UK’s leading producer of high quality cultivated grass turf, with sales of over 165 million rolls in its more than 40-year history, Rolawn now has scientific evidence to prove that focusing on a younger thinner cut turf, which is technically superior because of accelerated root establishment, is the future. This enables the turf to have increased adaptability with greater suitability for the wide range of growing conditions found across the UK.

The move to the younger thinner product was prompted by the company’s constant consideration for the elements that influence the market. These include the steady withdrawal of certain approved herbicides, pesticides, insecticides and fungicides, the amplified extremes in weather patterns impacting both turf cultivation and the stress put on lawns; the need for customers to have technically superior product and increased consideration for our environment and our impact upon it.

Customer feedback has further underlined the merits of younger thinner cut turf, with Rolawn seeing its already excellent customer satisfaction levels improved since the product’s introduction. Rolawn believes its Medallion turf to be probably the most healthy, adaptable and flexible turf on the market, whilst retaining its already well-known light weight and ease of laying, giving improved performance with better lawns useable within shorter time frames.

Younger thinner turf does have the capacity to be more active and this is an important element in why turf is so highly perishable once harvested. Active grass plants produce respiration gases that increase perishability and this is where Rolawn’s holistic and planned approach to turf production kicks in – problem solved with Rolawn’s unique patented Profresh® system. Introduced in 2014, Profresh® uses advanced techniques which extend the shelf life of its turf by up to three or four times within commercially viable constraints.

Paul Dawson, Managing Director of Rolawn comments, “The research and a time lapse video completed by the STRI once again show how we think ahead as a Company. We have worked to develop a turf product that addresses the issues we face going forwards whilst giving customers a technically improved product better able to deal with issues such as more extreme weather patterns. We feel a heightened concern and sense of responsibility from consumers for where and how products are manufactured, modern Medallion harvested younger and thinner is a challenge that has taken years to develop but has addressed those concerns. The key is better lawns, more easily established with increased adaptability to individual on-site growing conditions, produced in a more environmentally sympathetic way due to a reduction in inputs.”

The research results are clear for all to see in the time-lapse video produced by the STRI where Dr Tom Young shows and explains the difference in the rooting characteristics of younger thinner cut turf versus older thicker cut turf. This can be viewed on the  Rolawn website or YouTube channel.

Important update: Temporary 6.5% surcharge effective 7 April 

At Rolawn, we are committed to maintaining the high standards of quality and service our customers expect, so we want to be open with our customers about a change that will affect pricing from Tuesday 7th April. 

This decision has been taken in response to disruption to energy supplies, which has led to significant increases in wholesale prices, affecting not only fuel and fertiliser but also costs throughout our wider supply chain. As a business that relies heavily on fuel for both transport and operations, these sustained cost pressures have become increasingly difficult to absorb.  

While we have worked hard to mitigate the impact, the scale and pace of recent price increases have now exceeded what we can sustain internally, and we therefore need to recover a proportion of these externally driven increases. 

From Tuesday 7th April, a temporary 6.5% surcharge will apply to all products.  

We know that any increase in price is frustrating, particularly at a time when many businesses and households are already feeling under pressure. That is why we want to be clear that this is not a decision we have made lightly, and not one we wanted to make. It has been introduced solely to help offset unavoidable cost inflation and allow us to continue delivering the quality, reliability and service standards associated with Rolawn. 

We will continue to monitor market conditions closely and will review this surcharge as soon as circumstances allow, providing reasonable notice of any changes. We recognise that any price increase is unwelcome, but this step is necessary to ensure the continuity and reliability of our operations during a period of ongoing uncertainty. 

We remain committed to providing the quality, reliability and service standards you expect from Rolawn, and we truly appreciate your understanding and continued support. 

If you have any questions, please contact our customer support team who will be happy to help.
