    Younger thinner turf produce healthier better lawns

    Independent research by the STRI has underlined the credentials of younger thinner turf. This is due to its ability to root more quickly than the traditional older thicker cut product. This allows 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 an older thicker cut side by side for 50 days. After 20 days, the younger thinner cut turf showed deeper, denser and more vigorous rooting. Surface appearance was also better, with its higher Normalised Difference Vegetation Index score. This is a measure of turf health and quality.
    STRI research manager, Dr Tom Young commented: “Initial visual appearance of the younger thinner turf was superior to the older turf. This effect lasted 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. It continued to do so 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. This shows that younger thinner turf displays better rooting capabilities. It also indicates that young roots are more likely to regrow after harvesting.
    Rolawn has evidence to prove that a younger thinner cut turf is superior because of accelerated root establishment. This enables the turf to have increased adaptability for the wide range of UK growing conditions.
    The move to the younger thinner product was prompted through the company’s consideration for the elements that influence the market. These include the withdrawal of certain approved herbicides, pesticides, insecticides and fungicides. This paired with the amplified extremes in weather patterns impacting both turf cultivation and the stress put on lawns. The need for customers to have 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. Rolawn has seen its customer satisfaction levels improved since the product’s introduction. Rolawn believes its Medallion turf to be the most healthy, adaptable and flexible turf on the market. It retains its light weight and ease of laying. This gives 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 perishable once harvested. Active grass plants produce respiration gases that increase perishability.
    Paul Dawson, managing director of Rolawn comments: “The research and a time lapse video completed by the STRI once again show how we work as a Company. We have developed a turf product that gives customers an improved product better able to deal with extreme weather. We address customer concerns of manufacturing responsibility products. Modern Medallion harvested younger and thinner is a challenge that has taken years to develop but has addresses this. The key is better lawns, more established with increased adaptability to individual on-site growing conditions. These are more environmentally sympathetic way due to a reduction in inputs.”
    The research results are clear in the time-lapse video produced by the STRI. In which Dr Tom Young shows and explains the difference in the rooting characteristics of younger thinner cut turf. This is available on the Rolawn website or YouTube channel.
