Special Show
At the special show about sports field greens under the patronage of the German Turfgrass Society, lawn and seed specialists as well as manufacturers of care machines present their latest products and machines. Here, turfgrass specialists have the opportunity to compare different lawn types and to test special equipment under real conditions.
On a specially established green area including tee-off and fairway turf, which comprises a total of 4,000 m², manufacturers of golf course care machines demonstrate their programme live.
The trial lots on the demopark grounds are unique. Here, the most important turfgrass species from Lolium perenne, Poa pratensis, Festuca rubra sp., Festuca ovina sp. to Festuca arundinacea are presented as pure varieties. “Cross sowing” for the demonstration of mixing partners is a particular highlight. This allows visitors to draw comparisons with regard to leaf texture, leaf colour, turf density, and suitability as mixing partners.
During the entire trade fair, experts of the German Turfgrass Society (DRG), which is the patron of this part of the exhibition, are available for questions and counselling.
Posters and guided tours of the lots address special lawn topics with the focus on:
* Mixture types according to RSM
* Soil loosening
* Shear strength of sports lawn
*Growth regulators in the lawn
* Soil additives and biostimulators
* Lawn irrigation and water quality
In a “workshop turfgrass sods" developed as a new idea, the characteristics and the performance of this construction material for gardening and landscaping will be presented with the aid of practical examples.
Lawn types: play and amenity turf, extensive lawn, Robusta lawn
Sod types: Standard roll, large roll, jumbo roll
Planting parcours for gardening and landscaping: soil preparation, planting, aftertreatment.
All experts agree that the special show about sports field greens at demopark 2011 will be a particular highlight.
Dr. K. Müller-Beck / Dr. Nonn: “Mixture types according to RSM”
"Lawn mixtures contain suitable species and different varieties with defined properties. However, the quality of a mixture only becomes apparent after sowing when the desired species establish themselves in the lawn. In this regard, the “cross trials” on the lawn area at demopark provide astounding information. Variety characteristics, such as turf density, texture, or competitive force are shown in an immediate comparison of different "RSM mixtures" and the "Tiergarten mixture".
Dr. W. Prämaßing : “Measuring criteria for soil loosening are convincing”
Soil loosening measures influence the soil-physical properties of the carrying layers of turf on golf courses and lawn areas. Penetration resistance established with the aid of a penetrometer can be used as a practically applicable measurement criterion in order to show the loosening effect.
Loosening equipment and test measurements are demonstrated on the trial area.”
Prof. Gert Bischoff: “Shear strength of sports lawn”
“Secure footing on the lawn is highly important for successful playing in both golf and soccer. The rooting of the turf is often the factor which decides to what extent divots are knocked out or kicked out like during soccer, for example. At those spots where the turf is no longer dense enough, the rootzone layer of the lawn itself must have sufficient shear strength so that the lawn can nevertheless be used for sports.
So far, virtually no demands have been defined for this functionality. The draft of the new sports lawn standard DIN 18035-4 only requires a laboratory trial for the rootzone layer of the lawn. For this reason, information and demonstrations around the topic “shear strength” will be provided near the lawn trial area at demopark + demogolf.”
Dr. Fritz Lord: “Growth regulators in the lawn"
“Growth regulators are an effective tool which allows lawn growth to be precisely controlled and exerts a positive influence on the quality and functionality of lawn areas. Their use is becoming more and more important on sports and golf lawn areas as well as public lawn in Germany. Less grass growth considerably reduces mowing requirements. As a result, the quantities of cut grass decrease, which leads to lower disposal expenses and reduces CO2 emission due to mowing.
The effect of these agents will be demonstrated at the special show about sports field greens.”
