To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees. Adding it to the soil surface may not be as effective. If you have a well-established lawn and trees, scatter the rock phosphate over the landscape.

phosphate fertilizer industry suggested an independent estimate of world phosphate rock reserves and resources was needed, since major efforts in this area concluded 15-20 years ago. This study was conducted as part of IFDC's Strategic Framework: 2009-2013 primarily using publicly
Phosphoric acid is produced by reacting sulfuric acid (H 2 SO 4) with naturally occurring phosphate rock. The phosphate rock is mined, dried, crushed until 60–70% of the rock is less than 150 μm in diameter, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate ...
