Research Farms Field Days

Field days give farmers and the public a chance to see research projects in progress and talk with the researchers involved in the experiments. But they also provide the opportunity to view the latest in modern agriculture. Anyone is welcome to attend.

Topics of field days in the summer typically cover corn and soybean production, including insect and weed management, soil fertility, tillage systems, water quality, planting dates, crop population, manure management and value-added crops.

Those visiting Iowa State farms with livestock (marked with *) are asked to take several precautions if they have been at another livestock operation. Those who have recently returned from a trip abroad are asked to wait five days before visiting Iowa State farms with animals. Visitors to farms with livestock are asked to change clothing and footwear after being in any livestock operation, foreign or domestic; and to refrain from bringing any food items to the research farm. If you have any questions, please call the Research and Demonstration Farms office at (515) 294-5045 or visit

The public is welcome to attend these field days, which take place rain or shine. There is no charge, unless noted.

Field days consist of tours of research and demonstration plots. Topics vary for each farm depending on local interest and conditions, but the early summer field days usually deal with corn and soybean production.

Many of the farms plant and maintain vegetable and flower gardens with help from the Department of Horticulture to provide gardening ideas and display new varieties available in Iowa.
