Both are high in calcium and both are high in phosphate. Those are the similarities; what are the differences?

Soft Rock Phosphate

Bone meal

Quote:
Source of calcium and phosphorus recommended for bulbs, tomatoes, and other vegetables. Analysis will range from 2-12-0 to 4-12-0 with 2 percent to 5 percent calcium. Soft rock phosphate is better and cheaper.


You can check the library for this information. On the home page look in the center for the Library of Organic Information. There's lots of great information there.
