Bone meal or burned bone meal - Bone ash

[baxbax]

Hello, want to use bone meal for soil mix but confused between bone ash and bone meal which is better?
I read bone ash has a lot more P but not sure which is better

Bone meal is high in P but is very expensive for the amount of P available. Bone char (burned bone meal) has more available P and is a much better value than bone meal.
