The Dixon Springs Agricultural Center is the southernmost agricultural research center for the University of Illinois.  Since 1960, fruit and vegetable research and extension outreach has been conducted on-site, providing Midwest growers with a wide range of information on various topics. The local food movement has increased year-round demand for locally grown produce, but in Illinois, local food production is limited by climate. The use of high tunnels for season extension is a valuable tool for specialty crop growers wanting to expand the production capacity of our temperate, Midwestern climate, and Illinois has seen a boom in the utilization of high tunnels to meet this demand.

Beginning in 2010, fruit and vegetable research and demonstration at DSAC transitioned from open field production to protected culture production, utilizing three, commercial size high tunnel structures on site. High tunnel systems allow growers to provide markets with fresh, locally grown products nearly year-round, not only creating increased economic opportunities but also increasing local food availability to help address food insecurity.

High tunnel production and management is of interest to both seasoned growers and beginning farmers as they look for economically viable ways to increase revenue. Research and demonstration trials conducted at DSAC provide timely recommendations and best management practices including variety selection; integrated pest management recommendations for insect, disease and weed problems; high tunnel production methods; and general information for new and beginning farmers.
