Transport vehicles and accommodation are powered by self-generated solar power, excess power is routed to the clubhouse, enabling an annual saving of 80,000 tons of CO2. We now analyzed the soil and lawn using an irrigation water filter (iron) and a car wash with a water circuit. In order to promote sustainable care and the environment, the choice of fine Festuca grasses was clear. The greens are dominated by Rubra Trichophylla (50%, Viktorka von Barenbrug), which requires very little input and is very disease tolerant. On tees and fairways there is a mix of Trichoyphylla, Rubra Litoralis and Rubra Commutata (30/30/40, also Barenbrug). Dollar spot is hardly an issue. Red tip is quite common. Tees and greens are constructed in USGA Spec close grain size range, but without gravel. Ceramic particles from the American company Profile were added to the greens, which differs from conventional peat, lava, ash, etc. This results in the advantage of higher porosity and water binding of no more than 14-15% throughout the entire base layer. This results in a considerable increase in root mass, with well-known positive properties. For every 85% sand there are 15% PPC (Porous Profile Ceramic). The drainage system is not constructed in a herringbone style, but is developed as individual pipes with entrances through catch basins on both sides. This means that consistent cleaning and maintenance is always guaranteed.   I would like to once again thank all the members, some of whom took a long journey to be there on this day.
