Technical Abstract: Having a dry year? Some farmers participating in a demonstration project for a new irrigation system sure aren't. Researchers in the Maumee River Basin in Ohio developed a recirculating irrigation/drainage system that increases crop production while protecting water quality. The Wetland Reservoir Subirrigation System (WRSIS) is comprised of a subsurface drainage pipe network, a constructed wetland and a water storage reservoir. The system applies irrigation water through the pipes to the roots, captures and treats subsurface and surface drainage and stores the water for reuse. It operates in a closed loop, thereby minimizing runoff of sediment, nutrients and pesticides into the Maumee River.
