High tunnel production of fruits and vegetables is the topic of upcoming workshops sponsored by Iowa State University Extension and Outreach. The workshop will be held at the ISU Extension – Hardin County office in Iowa Falls on Nov. 17, and the ISU Extension – Linn County office in Marion on Nov. 19.
Iowa farming may change forever with the increased use of high tunnels. These simple, plastic-covered, solar-heated structures offer many benefits to farming – some benefits that common row crop vegetable farming cannot provide. Iowa State University Extension and Outreach has released a new publication that describes the cost benefits of high tunnel farming.
High tunnels are inexpensive, simple, passive-solar greenhouses that allow growers to extend the season and produce high yields of quality produce earlier and later than field-grown crops. However, soil around a high tunnel can erode or become saturated after rainfall. This potential problem has been turned into an asset, thanks to a one-year research project conducted by Iowa State University Extension and Outreach.
