Compost is not one thing. We use compost to describe a whole range of soil amendments. And some of them don’t live up to what we want compost to do. On this week’s episode of Shaping Fire, host Shango Los welcomes back soil biologist Leighton Morrison to talk about the varieties of compost and the benefits and challenges of each, the structure and micro-biology of inoculant organic matter, how to make a microbe-rich cold compost without pathogen risk, and a whole lot of insight into the grading, use and storage of compost.
