Photosynthesis growth system for natural grass

The lumigreen system is developed to solve present problems connected with poor growth conditions and quality of grass on sport turfs like football fields, tennis fields and golf greens.

The vision is to develop and sell the LUMIGREEN system: A photosynthesis growth and maintenance concept for natural grass. The system will be specially designed for use and installation on sport fields like in football stadiums, tennis stadiums, golf greens and so on. * Higher frequency of use of sports turfs, giving * Higher earnings from games and television rights * Higher quality of the sports turf, as well as * Lower maintenance costs. The recent trend of building football stadiums with extensive roofed stands has created an unhealthy biological situation for the turf grass on the field. The roofed stands block the sunlight and the natural photosynthesis process in the grass stops. The grass stops growing and eventually dies. Other conditions, like poor air exchange over the grass field creates a general lack of CO2 (carbon dioxide), which is essential for photosynthesis, as well as a moist microclimate above the grass leaves of the football pitches, leading to a high level of mechanical friction which utterly destroys the grass leaves and root system. Presently the arena managers seek solutions to these problems in changing the whole grass fields using new sod ('roll-on-turf'), but, this is both an expensive, and at best a medium quality solution. INTRAVISION A.S. has applied for a patent on the LUMIGREEN photosynthesis system: A cloth integrated with a powerful lighting system, is kept floating on an air pillow right above the grass field. The air pillow is established by a series of fans, and the air is saturated with extra CO2 to speed up the growth process. The system can be made in different sizes from a few square metres to a full-size covering, over a whole football field. The LUMIGREEN system has been biologically tested in research, setup by Professor Jon Einset at the AGRICULTURAL UNIVERSITY OF NORWAY (NLH). The test setup resulted in up to 15 mm growth every 24 hours for grass on football pitches (perennial ryegrass), and approximately 8 mm for grass on golf greens. The project has two different phases: A technological development phase, and a biological testing phase. The project plan is: * Development of a series of small test units (one square metre) for initial testing of different LED (Light-Emitting Diode) light setups. * Development of special electronics able to deliver the right low-voltage power from a decentralised position. * Production of a prototype of the whole system approximately the size of a tennis field (11X23 metres). * Biological testing on sites (football, tennis, golf greens, etc.). * Long time biological testing of effects on grass using the small test units, for getting knowledge on potential for uses as indoor systems. Keywords: LED (Light-Emitting Diode), biology, sports turf.
