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.
