– Extra salt tolerant Increased salt tolerance Clean irrigation water is becoming a luxury and a scarce resource now and even more in the future. Whether the salinity is due to salt in the soil, salt spray, or contaminated irrigation water our 4Turf tetraploids are proven to be significantly more salt tolerant than standard diploid ryegrass. This gives a better plant growth and healthy looking turf. It is a known fact that sportfields, lawns, roadverges, golf courses etc. have problems in saline soils or in salty conditions. It doesn’t matter where the salt comes from: the soil, water supply, or windblown spray, if there’s too much salt, ordinary grass won’t grow to its potential. To solve this problem, DLF offers 4salt® mixtures, that will perform with or without salinity problems. The 4salt® logo is used to identify varieties and mixtures optimized for saline conditions. Our 4salt® mixtures will also perform well without salinity problems, so it is no risk to choose them as a safeguard, and be prepared for changes in the quality of irrigation water. Salt tolerance in lawngrasses (rel.) perennial ryegrass (4turf®) smooth meadow-grass Standard diploid ryegrass 0 50 100 150 200 – for turf production 4turf® – For the future ” T etraploids were first seen in a lawn grass situation over 25 years ago when the standard of turf quality in general was not as high. What is new is that this new generation of varieties we have developed are able to compete in performance and appearance with the best modern standard varieties. It has taken us over 20 years to achieve this. Even that first variety many years ago exhibited improved stress tolerance and this is what has motivated us as breeders to continue improving and refining 4turf®. 4turf® ” will open new horizons in Perennial ryegrass breeding. Christophe Galbrun Plant breeder Buus landscapers ” I am using 4turf® in my grass mixtures. This extends my seeding season so that I can seed in the spring and in the autumn. With 4turf® I get a quick establishment of the lawn, which leads to happy and satisfied customers. 4turf® ensures an attractive ” healthy lawn, we can always rely on good results. Morten Petterson Project manager Buus landscapers, Denmark Danny Vansweevelt - Landscaper ” Since the introduction of 4turf® by DLF, I am using the 4turf® mixture RecreaMaster ProNitro®. As a professional gardener, I need a grass seed mixture that ensures a perfect lawn in no time. The fast and strong development ensures a nice, uniform germination and growth. The goal is to be ahead of the weeds so they don’t have a chance to establish. I usually use the grass seed mixture with 4turf® in combination with the ProNitro® coating. Both when sowing new lawns and when renovating, it has proved to be a perfect mixture. The seed is somewhat heavier, which means that it sows well and ” gets good soil contact even when it is windy.
