Due to the emphasis on sustainability throughout multiple academic disciplines, a number of courses at Macalester partner with Common Harvest Farm in Osceola, Wisconsin to understand the complexities of sustainable farming and associated challenges in policy. Students take field trips to the farm to witness community sustainable agriculture (CSA) and the logistics of running a farm. Macalester students also have the opportunity to declare a Food, Agriculture, and Society concentration and intern with Common Harvest Farm.

The 40-acre farm was founded in 1989 as an outreach of an urban peace and justice community seeking a greater connection to the land and their food. It produces 40 different vegetables and herbs with a focus on the traditional carrots, tomatoes, green beans and potatoes. In addition to a regular season share, they offer a fruit and extended season share. Common Harvest Farm is owned and operated by Dan Guenthner, Margaret Pennings, and their three children Annie, Grace and William.
