Bone meal is the resulting powder one winds up with after grinding up bones.
At present, bone meal is only ever found in glowing pits. It cannot be used for any purpose and is, for now, just for atmosphere. Any bone meal present in the pit will disappear during the next season change.
It also appears as a custom food stockpile option that does not actually do anything except confuse the occasional wayward player; perhaps that is how you ended up at this page in the first place.
In reality, bone meal is made by grinding animal bones into a powder and is used as a fertilizer for plants and as a nutritional supplement for animals.
