AMES, Iowa - Proper water management is an essential skill for fruit and vegetable high tunnel growers. Since the plastic film covering prevents rain water from reaching the crop, the environment underneath is virtually a desert. Water is typically provided by drip irrigation lines placed beside the crops. Drip irrigation waters only the crop root zone, keeping the foliage dry which results in less incidence of foliage diseases associated with water on the leaves.

However, an estimated 1,800 gallons of water runs off a 30 x 96 foot high tunnel with each inch of rain. That volume tends to puddle around the sides of a high tunnel or requires drainage. Rather than letting water create a saturated area around the high tunnel, erode the soil around the high tunnelor go unused, Iowa State University Extension specialists have developed a system to collect the rain water and store it for reuse on the crops in the high tunnel. The system demonstrates a water collection system that was retrofitted on a Quonset style high tunnel with both electric and solar powered pumps.

The public is invited to a field day to learn more about this system and see the production and drip irrigation system in the high tunnel. The field day will be held on July 12 at 6:30 p.m. at the Armstrong Research and Demonstration Farm, 53020 Hitchcock Avenue, Lewis, Iowa. The farm is located 11 miles southwest of Atlantic.
