What if the soil beneath our feet was more than dirt—what if it was a living, breathing factory of life, memory, and communication?

In this extended conversation, Tim Sallin sits down with Buford Creech, agronomist, soil steward, and teacher, whose lifelong work bridges the worlds of science and faith. Together they explore the microscopic wonders of the rhizosphere, the role of fungi as soil architects, the miracle of photosynthesis, and the hidden chemistry that sustains plants and people alike.

They also look squarely at today’s challenges: unintended consequences of industrial agriculture, the tipping points facing global food systems, and the devastating impact of HLB (citrus greening) on Florida’s groves. Buford offers both practical regenerative strategies for farmers today and bold speculation on therapies yet to be explored.

Whether you’re a farmer, a scientist, or simply someone curious about the miracle of life, this is a rare chance to learn from a voice that sees the soil not just as chemistry, but as communion.

In this episode of The Ground Up Podcast, I sit down with Lake County Commissioner Sean Parks for a wide-ranging conversation on local leadership, land conservation, and the future of Florida’s landscapes.

We explore the overwhelming success of the Lake Forever referendum, which passed with 80% voter approval to fund land conservation in Lake County, and discuss planning tools like Transfer of Development Rights (TDRs), and the proposed Wellness Way Landscape Ordinance under consideration right now. 

Sean and I had originally recorded this live at the Florida Wildlife Corridor Foundation's Corridor Connect Summit. Sadly technical issues made publishing it impossible. I am grateful to Sean Parks for agreeing to reshoot at Cherrylake. 

I hope you enjoy this episode! Please leave me some feedback in the comments.
