IMPROVED WINTER HARDINESS As temperatures drop, a plant’s metabolism slows down. But to a lesser extent in 4turf®. 4turf®’s larger energy reserves give it the ability to grow at low temperatures, which makes tees and fairways better able to withstand winter wear. In trials undertaken in Finland, 4turf® showed superior winter hardiness. In Scandinavian SCANTURF trials, it ranked number 1 for general turf quality. WINTER COLOR AND SURVIVAL OF RYEGRASSES Index 110 105 100 95 90 85 Diploid perennial ryegrass 4turf® Winter color index Winter damage index ATTRACTIVE DEEP GREEN COLOUR AND MORE EFFICIENT USE OF NITROGEN 4turf® varieties exhibit a more attractive green colour than traditional diploid perennial ryegrass varieties. 4turf® leaves are a deeper and glossier green, which improves their visual appearance. With an improved cellular structure and more efficient photosynthesis, 4turf® varieties keep their colour all year round, even when light levels are low. Better colour and increased root mass also mean that 4turf® is a more efficient nitrogen user. That’s good for the environment and for the sustainability of your turf management because 4turf® needs less nitrogen fertiliser to keep a beautiful visual appearance. ENHANCED SALT-TOLERANCE Clean irrigation water is a scarce resource, and one that is likely to become even more scarce in the future. Whether the salinity in your golf course comes from contaminated irrigation water, sea spray or salt in the soil, our 4turf® varieties will ensure that your turf will not take damage. 4turf® varieties are proven to be significantly more salt-tolerant than traditional diploid perennial ryegrass varieties, which leads to better plant growth, healthy looking turf and a healthier golf course. EXCELLENT SHADE-TOLERANCE In trials, our latest 4turf® varieties exhibited greater shade and wear-tolerance. Even at reduced light levels of just 60% PAR (photosynthetic active radiation), they showed greater ground cover and wear-tolerance than traditional diploid perennial ryegrass varieties. This makes them perfect for golf course fairways and tees, where 4turf® can grow between trees and still keep your golf course fresh and green.
