Question about bone meal

[baxbax]

Hello , I was looking for bone meal Locally and a Animal feed supplier man told me Its better I use Burnt bone powder because it contains 15% P instead of using steamed bone meal contain 5% P and 15% calcium

this is the analysis of steamed bone meal and its like I heard for him :

Is there any Advantages using burnt bone meal instead steamed one ?
