Irrigation Systems
There is an effort in the irrigation industry to develop new technologies to reduce water use, and many companies have made great strides in this direction. With the onset of drought conditions showing up across much of the United States, this has become a major priority.
In some areas, drip irrigation systems can reduce water use by half. In fact, research done by Bernd Leinauer revealed water use on subsurface-irrigated research plots was shown to be 90 percent to 95 percent less than on sprinkler-irrigated plots.
These subsurface-irrigated plots also had root masses greater at lower depths than those irrigated with conventional sprinkler systems.
If these systems could be used on golf courses, they could make a great contribution to water savings. In addition, use of composted manures and watering systems that can introduce water below the surface and keep the soil surface and turf thatch layers less hydrated could help in the reduction of disease and reduce the use of pesticides. That's why my company decided to build on the existing success of subsurface irrigation systems in the creation of the new system. |
The small diameter pipes combine the subsurface irrigation and air delivery components of the Pennfield system. The white, flat pipes provide drainage and help recycle water from rainfall and irrigation cycles. |
The potential benefits are:
1. Reduced water inputs
2. Reduced pesticide applications
3. Increased drought tolerance
4. And, in general a more durable and playable surface.
Both David Casnoff and Penn State University have created a collaborative effort to study and develop more environmentally sensitive turf grass management systems including the pennfield system. An Endowment was set up in David and Cheryl Castoff's names to create a cooperative effort with the industry to both research and develop these types of systems. The benefits to the turf grass industry should and will be far reaching.
