BLOOMFIELD, Iowa – Iowa State University Extension and Outreach is hosting a workshop for commercial fruit and vegetable farmers who are growing produce in high tunnels. ISU Extension – Davis County is sponsoring the free event to be held Tuesday, Oct. 30, at the extension office. The Davis County Extension office is located at 402 E. North St. in Bloomfield, Iowa. The workshop will be held from 8:30 to 11:30 a.m., with registration beginning at 8 a.m. Light refreshments will be served.
“High tunnels are inexpensive and simple passive-solar greenhouses in which crops are grown directly in the soil,” said Joe Hannan, commercial horticulture specialist with Iowa State University Extension and Outreach. “While they allow growers to extend the season and produce high yields of quality produce earlier than field-grown crops, they have different challenges than field-grown crops that require careful planning and using the right tools and strategies to overcome these challenges.”
Representing ISU Extension and Outreach at the workshops and leading workshop discussions will be Hannan, Ajay Nair, extension vegetable specialist, and Linda Naeve, extension value added ag specialist. Topics to be covered at the workshop include managing high tunnel insects including aphids, spider mites and whiteflies with a special look at new insect problems that are developing across the Midwest. The specialists also will discuss the use of cover crops in high tunnels for building soil quality and reducing soil disease problems, as well as collecting leaf samples for determining plant nutritional needs.
For planning purposes, please pre-register by Monday, Oct. 29, with Janis Howard at the Davis County Extension office, (641) 664-2730 or e-mailing Janis at firstname.lastname@example.org.
