Bone Char is calcined (kilned) bone meal used primarily for water purification and refining sugar. Bone Char 0-16-0 contains more than 16% available phosphate (P2O5) and 32% total phosphate plus 33-34 percent calcium. It is OMRI listed and can be applied without restriction on certified organic farmland. Bone Char 0-16-0 is currently less expensive than phosphate rock and significantly less is needed per acre to supply the same amount of available phosphate. The consistency of Bone Char 0-16-0 is fine, like table salt and its density is ~80 pounds per cubic foot.
