Water Soluble Calcium Phosphate- Korean Natural Farming input.
Charr the bones until they sound like porcelain, then soak in Brown Rice Vinegar (from grocery store).
What the bubbles!

I love your living soil recipe though Alchemist! ❤️
Check out Chris Trump on YouTube, (no relation to the ex-prez) he is great for KNF, also check out Dr. CHO who made KNF and his son who came up with JADAM. Another great farming method
