A practical biodynamics conversation rooted in fungi, pasture, and living soil.
ChangeUnderground follows biodynamic farmer Mark Rathbone as soil carbon shifts from a broad concept into the daily practice of growing seasonal vegetables.

Soil life, climate repair, practical regeneration.
ChangeUnderground treats soil as living infrastructure, not inert growing medium. Led by John Moore, it moves between regenerative agriculture, biodynamics, climate reports, weed ecology, and the everyday work of growing food with fewer chemical inputs.

ChangeUnderground is a regenerative agriculture show built around one governing idea: soil is alive, and farming succeeds when that life is protected. John Moore brings a practical grower’s attention to weeds, roots, fungi, mulch, photosynthesis, animals, and carbon, then connects those details to climate change and food security. The show can be intensely hands-on. A blackberry patch is not merely a nuisance; it becomes evidence of bare ground, nutrient storage, stock pressure, and the limits of a spray-first response. Chaos gardening becomes a way to think about diversity, companion planting, year-round green cover, and the stability that comes from biological complexity. Biodynamics receives similar treatment through the Mark Rathbone interview, where soil carbon, vegetable growing, superphosphate, fungi, and the weakness of lifeless soil tests are discussed in plain terms. ChangeUnderground also reaches back into human history. Episodes move from Homo sapiens in the Pleistocene to Holocene agriculture and then into the Anthropocene, asking whether old bodies and old habits can handle new ecological conditions. Climate reporting is part of the mix, including a close pass through the sixth IPCC report and the uneasy signs of seasonal disruption. The show is openly critical of chemical-dependent agriculture, seed and chemical companies, monoculture, and the idea that merely holding decline in place is enough. It prefers regeneration over sustainability. That stance gives the series urgency, but the best episodes stay concrete: slash the blackberry, keep ground covered, feed soil biology, grow food closer to home, add diversity, and watch what nature is already trying to do. The tone is direct and occasionally wry. It is not polished corporate climate content. It sounds like an opinionated field notebook from someone trying to reason through the living world, one paddock and garden bed at a time.
Made for: For gardeners, small farmers, regenerative agriculture learners, and climate-minded listeners who want soil biology explained through concrete examples. It especially suits people interested in moving beyond chemical fixes toward ecological observation and repair.
What sets it apart: ChangeUnderground blends practical growing advice with archaeology, climate science, biodynamics, and sharp criticism of industrial agriculture. Its strength is the way it reads weeds, crops, microbes, and weather as signals from one connected system.
Decarbonise the air, recarbonise the soil.To feed the world, to clean the air and water, we need to change what we do with our soils.This podcast looks at the many variants of regenerative food growing. How? Why? When?We must be the ChangeUnderground!

A practical biodynamics conversation rooted in fungi, pasture, and living soil.
ChangeUnderground follows biodynamic farmer Mark Rathbone as soil carbon shifts from a broad concept into the daily practice of growing seasonal vegetables.
A grounded conversation on biodynamic vegetables, living soil, pasture rotation, mulch, microbes, and the limits of some soil testing.
Mark Rathbone makes biodynamic vegetable farming feel like a set of practical decisions rather than a loose philosophy. From a seasonal vegetable farm in northern Victoria, he connects soil carbon to rotation, pasture, mulch, roots, grasses, and microbial life, explaining why…
