Capillary Concrete launches the Hydroponic Turf System

Capillary Concrete, best known as the supplier of golf’s most scientifically advanced bunker liner product, has launched a revolution in golf turfgrass management. The Hydroponic Turf System offers course managers the opportunity to make huge reductions in the amount of water needed to maintain high quality turfgrass, while at the same time promising major increases in turf health.

The system uses the capillary properties of Capillary Concrete to enable both drainage and irrigation from below and to precisely regulate the moisture content of the turf’s rootzone.

Martin Sternberg, Capillary Concrete inventor and CEO, said: “The system divides the turf into two areas of equal size. A control basin automatically oxygenates and pumps or drains water between the two areas on a regular schedule. The system is powered by a small solar panel and the water levels in the turf profile can easily be adjusted.”

The Hydroponic Turf System enables massive increases in gas exchange below the top four inches of the rootzone – the area which conventional aeration methods do not adequately service. Because carbon dioxide molecules are heavier than those of oxygen, the system pushes out the heavier molecules and sucks oxygen into the turf profile by raising and lowering the water table. It also delivers optimal levels of nutrients directly to the rootzone.

Sternberg said: “We have been researching this application of our technology for five years, and the results are remarkable. Irrigating from below virtually eliminates evaporation, and our tests show up to 85 per cent savings in total water used under our Hydroponic Turf System. Irrigation costs can be lowered by up to to 30 per cent, and the level of gas exchange in the rootzone can be increased by an almost unbelievable 6,000 per cent. Using hydroponics in this way will increase the lifespan of tees and greens, it will help superintendents deliver superior turf from dryer surfaces with lower maintenance costs and a much smaller environmental footprint.”

Capillary Concrete is currently looking for golf clubs to participate in a pilot programme to adapt the patented Hydroponics Turf System to local conditions and climates. Pilot partners will receive the new system, and also comprehensive support services enabling them to install, test and evaluate the benefits of the system for tees and greens.
