Here's my living soil recipe for just a little over a yard of soil (1.2 yards) There's a million ways to skin a cat and this is in no way a end-all be-all recipe. These are just what I belive to be the best ingredients I had readily available to me. The worm castings are Organics Alive, the compost is from Malibu. Most of the dry ingredients are from Down to Earth, Sparetime Supply, or Gaia Green. The biochar is from Pacific Biochar. The black cinders are from a landscape yard and are black volcanic rock local to me, and used for aeration in place of perlite. I mix everything up, spray it with compost tea, and put it in a 2 yard tote to cook up for 4-6 months before planting. I will use this soil for 5-6 seasons before I cycle most of it into my veggie garden and mix a new batch. If anybody has any questions feel free to ask.
