bone meal

bone meal, finely ground bone used as a fertilizer for its content of phosphate and nitrogen (about 23%–30% available phosphate and 2%–4% nitrogen); it is an expensive form of phosphoric acid when compared with superphosphates. Bone meal is also fed to farm animals to supply needed mineral food constituents, e.g., calcium and phosphorus.
