Improving the availability of phosphorus from rock
2018-10-3 Rock phosphate contributes in producing of the world’s phosphate fertilizers and mostly contains some forms of the apatite mineral. However rock phosphate is a mined rock that contains clay and limestone as well as a high concentration of phosphorus. Rock phosphate actual composition varies depending on its source but it contains approximately from16 to 20 % phosphorus. U.S geological survey by Jasinki, 2010estimated the world total rock phosphate
Heavy metals input with phosphate fertilizers used in
Rock phosphate contained the highest levels of cadmium and zinc, chromium was enhanced in diammonium phosphate and copper and lead were high in one superphosphate sample. Urea-phosphate contained the lowest levels of heavy metals.
Using phosphate rock to immobilize metals in soil and
2006-4-15 Phosphate rock also supplies calcium in addition to increasing soil pH, thereby providing better growth condition for the fern, which prefers to grow in a lime-rich environment (Jones, 1987). Therefore, we hypothesized that the addition of phosphate rock reduces metal uptake while it also increases arsenic uptake by P. vittata.

2016-8-3 The phosphate on the rock is in equilibrium with phosphate in the water. So having the rock in water with a low to very low phosphate concentration will slowly remove it from the rock. You can do that before setup, or you can keep it low during the cycle (or both). There are a variety of ways to accomplish this, including GFO, lanthanum

Abstract Phosphate-induced immobilization is recognized as one of effective in situ remediation methods for heavy metal contaminated soils. Phosphate-based minerals that adsorb, chelate, or complex heavy metals in soil were greatly concerned as effective heavy metals immobilizing materials.
