Turf specialist Barenbrug has developed grass that sends roots down more than a metre and can be used to help stabilise loose soil.
Barenbrug’s new RTF — Rhizom-atous Tall Fescue — is an all-purpose grass that has been bred to offer wear tolerance.
The company has carried out its own tests on RTF, as well as allowing it to be trialled by the Sports Turf Research Institute at its headquarters in Yorkshire.
It has been tested on its own and as part of a mixture. In salt tolerance trials, it was shown to be significantly more tolerant than three perennial ryegrasses also tested. It was only marginally less tolerant than the company’s Barcrown slender creeping red fescue, which was the most salt tolerant.
RTF underwent rooting depth trials at STRI’s clear-view growing section, which allows growth and roots to be seen through Perspex.
Back in April, it was sown in three different rootzones — sand, indigenous soil and clay. The roots have reached one metre in depth and are still growing.
Barenbrug UK area sales manager Jane Leyland said: “RTF’s incredible rooting capability means it is perfect for application where soil stabilisation is an important requirement.
“Other characteristics, such as rapid recovery, high tensile strength, fast establishment of laid turf and excellent performance in wear, shade, salt and frost make it the ideal solution for many golf, other sports and landscaping applications,” she added.
