I wonder what is actually happening during the "cook" time recommended for supersoil mixes. Does it sit for a month because it takes that long to fully populate with wild bacteria and fungi and get tbe nutrient cycling going? Or is it just that the microbes break down insoluble food during that month?
Its one and the same, they are breaking down the food and storing it in microbial bodies that can be cycled. More mature soil can have a higher nutrient density without being hot because the nutrients are in the bodies of living things, not fully available but ready to become available.
