FARMER-LED • ROOTED IN ORGANIC

THE MARBLESEED ORGANIC FARMING CONFERENCE BRINGS FARMERS TOGETHER TO LEARN, CONNECT, AND SHAPE THE FUTURE OF ORGANIC AGRICULTURE.

For nearly four decades, this annual gathering has been a cornerstone of the Midwest’s organic movement, uniting farmers, educators, and advocates for hands-on learning, shared wisdom, and community rooted in farmer-led, organic principles. The 37th Organic Farming Conference (Feb. 26 - 28, 2026) saw guests from all over the Midwest, as well as from farther afield, meet for hands-on learning, passionate keynotes, informal farmer-to-farmer sharing, and workshops on all production types. Read a short reflection from a new Marbleseed board members. Plans are underway for 2027 – stay tuned!
