diatomaceous earth is a beautiful resource, we use it for our dogs, chickens and soil. Its a total necessity for farming, never realised it had silica in it, thanks @The_StonedTrooper. Ironically I used to sell it to the ladies at our local farmers coop.
I am starting to think, Bokashi? I attended a workshop recently, and the guys hosting it were not selling the product, just sharing the knowledge. You had to see their smiles, and their damn plants, FIRE. I think it was bran they were mixing the EM ( ? ) with, but I am sure barley. Next step is the bokashi trail and looking forward to it.
