Dig in with On-Farm Learning and Trainings
Join us every summer for on-farm learning at Marbleseed Organic Field Days. Field Days hosted by regenerative and organic farmers across the Upper Midwest who are using innovative organic farming practices and feeding their communities. From small urban farms and midscale silvopasture operations to larger scale row crops, we aim to offer field days for every type of farm. Come connect with community and get fresh ideas to try on your farm.
Marbleseed's Trainings connect farmers with the tools they need for a thriving farm business, supporting the growth of organic acreage, generating more revenue for small-scale farmers, and mitigating the impacts of climate change with farming practices that value land stewardship and whole ecosystem health.
Special Instructions for Visiting Farms with Livestock
Biosecurity is important on all farms, clean shoes and clothes are particularly important at field days where livestock are present. Marbleseed asks that all attendees observe the following biosecurity protocols when visiting farms with livestock.
- Wear clean or disinfected shoes that have not been worn on other farms with livestock or livestock buildings, or around a dense population of wild birds.
- Wear clean clothes that have not been worn around other livestock.
- Upon request of the host or staff during the field day, you may be asked to wear disposable plastic boot covers (provided by Marbleseed) over your shoes.

Navigating the Organic Transition: Key Decisions for Farmers
Thursday, April 24 | 4 – 6 PM
Transitioning to organic presents both exciting opportunities and unique challenges. This webinar, Navigating the Organic Transition: Key Decisions for Farmers, will guide producers through critical considerations for a successful transition process, including understanding and prioritizing equipment purchases, navigating the selection of certified organic seeds, fertilizers, and pest inputs to maintain compliance and maximize yield, and implementing best practices for record keeping and documentation to meet organic certification requirements and improve farm management.
Join Sam Oschwald and Kevin Mahalko for practical strategies and a discussion on how to make informed, cost-effective decisions during your organic transition. Whether you’re just starting or already in the process, this session will provide valuable guidance to support your farm’s success.
Sam Oschwald is a Wisconsin native who has been around vegetable farming and gardening for many years. He started in vegetable farming on an Amish horse-powered farm, and then learned from the Seely’s at Springdale Farm in Plymouth, WI. Seeking a formal education in horticulture, Sam moved to Lansing Michigan and studied under professor Dan Brainard at Michigan State University Department of Horticulture for 3 years. At MSU Sam researched mechanical weed control in vegetables. Sam is passionate about plants both personally and professionally, and has traveled all over the US, Caribbean, Europe, and Asia visiting farms and farmers and sharing new tools and techniques with American farmers through his presentations and articles (many of which can be found in Vegetable Growers News & Growing for Market). Sam now lives in Minneapolis with his wife Julia.
Kevin Mahalko farms 395 certified organic acres and milks 45 Holstein dairy cows in Gilman, WI. The Mahalko family has been involved in grazing networks since the 1990s and Kevin has worked as a grazing educator since 2008.
