I've often wondered about "composting" bones, or recycling them into the soil. Is there a practical way? Like roasting in or over a bonfire, then grinding them up? ("bone meal") Or dusting with hydrated lime. Or soaking.
Or is there a method like hugelculture where they decompose slowly without processing steps?
They must contain a lot of phosphate, calcium and protein (nitrogen).
