Phosphate: A Critical Resource Misused and Now Running Low ...
Phosphate: A Critical Resource Misused and Now Running Low. Phosphate has been essential to feeding the world since the Green Revolution, but its excessive use as a fertilizer has led to widespread pollution and eutrophication. Now, many of the world's remaining reserves are starting to be depleted. By Fred Pearce • July 7, 2011.

Phosphorus in diet: MedlinePlus Medical Encyclopedia
The main food sources are the protein food groups of meat and milk, as well as processed foods that contain sodium phosphate. A diet that includes the right amounts of calcium and protein will also provide enough phosphorus. Whole-grain breads and cereals contain more phosphorus than cereals and breads made from refined flour.

What is Phosphate Fertilizer? (with pictures)
Phosphate fertilizer in its liquid form can be easily applied to fields and crops. The process by which phosphate rock is converted to phosphate fertilizer involves treatment with sulfuric acid; the result is often called "super phosphate."This treatment with sulfuric acid draws the phosphates from the raw ore and creates a water soluble form.

Processing Phosphates for Use in the Fertilizer Industry
In the production of superphosphate fertilizer from phosphate rock, the rock is normally pulverized, mixed with sulfuric acid, and discharged into a den where the reaction between rock and acid proceeds. The fresh superphosphate is then removed from the den by an elevator and conveyed to storage for curing.

There is no elemental phosphorous in any food, processed or otherwise. Phosphorous in food is always part of a compound. "Phosphate" is the name of a polyatomic ion, PO4^3-. But it usually occurs as H2PO4^- or HPO4^2-, rather than PO4^3-. There is no difference in the occurrence of phosphorous in "whole food" or any other kind of food.
