Ultra Bioattivo: Inside a Regenerative Farm Above Florence

What does “ultra bioattivo” farming look like in real life? In this episode of Harvesting Wisdom, Mike McMahon visits a hillside farm overlooking Florence, Italy, where one farmer is using an intensely biological, small-scale approach to grow more than 40 varieties of vegetables and olives. Translated live from Italian, the conversation explores how the farm has operated for more than 12 years without fertilizers, pesticides, fungicides, or herbicides. Instead, the farmer relies on soil biology, compost, biochar, zeolite, Korean natural farming principles, mulch, water basins, and deep-rooted trees to support the land. The episode also dives into the farm’s unique composting process, including a thermophilic phase followed by months of resting in a forest windrow. Mike and his host discuss how cypress trees, mulched basins, and soil armor help slow runoff, recharge the aquifer, and keep water on the land instead of letting it wash downhill. The conversation also connects farming with human health, including the farm’s partnership with the University of Florence on gut microbiome research among customers. Mike relates this to his own water-saving trials with the University of Arizona using the same radicchio variety in the Yuma desert. The episode closes with a powerful look at community impact: 200 subscribing families, partner restaurants, word-of-mouth growth, and a shared belief that regenerative, biology-driven farming can be adapted and taught in many different places. Subscribe to Harvesting Wisdom for more conversations on agriculture, sustainability, soil health, food systems, environmental stewardship, and the people working to protect the land for future generations. Why Listen? This episode is a great look at regenerative farming in action, not just as an idea, but as a working farm feeding families and restaurants through soil-first practices. If you are interested in soil biology, composting, biochar, water conservation, Korean natural farming, farm-to-table systems, or the connection between food and health, this conversation offers a practical and inspiring look at what chemical-free farming can look like on a real hillside farm above Florence.
