Does anyone know if it will still have phosphorus in it?
My understanding is that the physical matrix of bones is comprised mainly of calcium and phosphorus. I know that the point of bone broth is to extract the minerals, but I'd suspect that what's left is still fairly high in phos.
Hmm, what a great idea! It sounds like something I should do, too... But here, feral dogs come through once in a while, and I'm sure they'd dig any buried bones up, which might be less than optimal for the plants over them. If I were to do it, I'd try to grind the softened bones, mix them with compost, and keep them for at least a week to compost before putting them in the garden soil under precious plants...
