Soil starts with dirt, which is rocks, sand, clay and silt. To our dirt we add diverse microbes which we have sourced from healthy, long standing, natural ecosystems in our area of Utah and surrounding states in the Mountain West region. To give these diverse microbes a place they want to stay and can survive, we have added tons of natural, organic carbon in the forms of leaves, grass (without chemicals), straw, hay, wood, manure, compost, and biochar. To all of this we have added diverse plants to provide living foods through exudate exchange, and animals in managed rotation to ensure adequate natural preparation of our soils without tillage.
This simply means we have more diverse microbes and lots of organic carbon. These two combine with dirt to make rich soil. Rich soil is soil that smells good. Smelling our soil can cause a release of serotonin, which not only smells good, it can make you happy.
