The need to cultivate a “living soil” that is full of microbes is something I hear frequently in the organic farming and permaculture world. As an apprentice at Rancho Mastatal this year, I have the unique opportunity to look further into the universe of these small and unseen allies. A way into this world was through the Ranch’s process of making organic fertilizer, one that harvests and inoculates the soil with Mountain Microorganisms (MM). This is similar to compost tea, where we create a fermented fertilizer with microorganisms such as manure.
