Compost isn’t just a pile — it’s the engine that drives soil fertility. In this conversation, Host Geoff Lawton and the regular crew, Sam, Eric, Ben are joined by guest Mohammed to unpack how compost really works, why biology matters more than recipes, and how the same principles apply from a backyard bin to large-scale farms. From hands-on composting stories to soil biology, bokashi, and scaling systems, this episode explores compost as a living process that feeds soil, plants, and people. If it once lived, it can live again.

Key takeaways:

00:00:00–01:10: Compost isn’t a thing you make once — it’s a living process driven by biology.

01:10–02:50: There’s more than one way to compost, and if life is breaking things down, it’s working.

02:50–06:10: You don’t really learn compost from books — you learn it by doing it, mistakes and all.

06:10–10:40: Compost works best when animals, gardens, and soil are designed to support each other.

10:40–17:50: With compost and biology, even worn-out land can recover faster than most people expect.

17:50–20:40: Compost builds fertility by feeding soil life first, not by feeding plants directly.

20:40–23:40: Most compost problems come down to balance, and carbon is usually the missing piece.

23:40–28:30: Good compost systems are designed first, and only then supported by the right tools or machines.

28:30–34:40: Compost follows the same rules at every scale — from a backyard pile to broad-acre farming.

34:40–53:30: Whether it’s aerobic or anaerobic, all composting relies on the same living biology doing the work.

53:30–55:30: Bokashi isn’t finished compost — it’s a fermentation step that prepares food scraps for soil life.

55:30–59:30: Compost is about returning life back to life and closing the cycle where it belongs.
