When phosphate rock is added to soil, it slowly dissolves to gradually release nutrients, but the rate of dissolution may be too slow to support healthy plant growth in some soils. To optimize the effectiveness of phosphate rock, consider these factors: Soil pH. phosphate rock requires acid soil conditions to effectively nourish crops.

To ensure a sustainable future and increase usable phosphate reserves for future generations, a new process called the "Getmore P" has been developed by Prayon Technologies. It allows the usage of low-grade rock, or even tailings, and converts it into a high value phosphate source, dicalcium phosphate or DCP.

The role that phosphorite formation, the ultimate source rock for fertilizer phosphate reserves, plays in the marine phosphorus (P) cycle has long been debated. A shift has occurred from early models that evoked strikingly different oceanic P cycling during times of widespread phosphorite deposition to current thinking that phosphorite deposits may be lucky survivors of …
