However, you should sometimes avoid using rock phosphate in your garden. Rock phosphate performs more efficiently when soil pH conditions are under 5.5, so you should test your soil with a meter before adding it. If your soil pH is high, phosphorus has trouble dissolving in water. This fertilizer needs acidic soil or will sit in the ground …
11.21 Phosphate Rock Processing 11.21.1 Process Description1-5 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding.

Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO 4 3–) fertilizers.Leaching or runoff losses from PR products like PO 4 3– fertilizers, animal feeds, and detergents could cause …
Glacial rock dust: This is said to have more pollutants than volcanic rock dust (such as basalt), but a lot of people seem to like it. Basalt rock dust: Some sources say basalt rock dust is the optimal kind of rockdust, and I've never heard anyone deny that directly. It has less silica than Azomite and diatomaceous earth, for sure.
