Indeed, I think a lot of people undervalue or are unaware of how important the soil microbiome is. That can't be restored at scale and requires the active participation of the other parts of the ecosystem, particularly the digestive tracts of animals. It's a complex interplay.
If you've ever seen cowpies sprouting grass out in some arid, quasi-desert environment, it's because their droppings contain grass seeds, insect eggs, worms, bacteria, fungal spores, and raw nutrients. Droppings are like ecosystem spores; they can help the originating ecosystem bootstrap itself in a new area, complete with hundreds if not thousands of species of microbiota, plants, insects, etc. Life is a team sport.
