Triple superphosphate (TSP)
Very finely ground phosphate rock (95% to 98% < 100 mesh) is mixed with phosphoric acid. With rock of 34% P 2 O 5 content, about 2.6 kg of acid P 2 O 5 is required per 1 kg of rock P 2 O 5. The phosphoric acid used is merchant-grade acid at 52% P 2 O 5 concentration. This is diluted by scrubber liquid to about 48% P 2 O 5.

Rock Phosphate Fertilizer
Commercial fertilizer it is mostly soluble P (in the form of phosphate). Within 24 hours this soluble P starts being converted to labile P and eventually to stable P. What this means is that most of the phosphorus fertilizer you add to the soil is available to plants for a short period of time, and then it gets locked away in the soil.
