Introduction: Phosphate as an Essential Mineral "The story of phosphorus is a long, fascinating one. But we are here interested primarily in knowing about its role in agriculture," wrote Vincent Sauchelli in "Manual on Phosphates in Agriculture" published in 1942. "Therefore in order to start at the beginning or our story we shall have to go back to the year 1840 – the year when ...

The presence of phosphate ore in Idaho was created by the rapid death of tiny organisms (i.e., algae and diatoms) living in what was once a shallow sea about 250 million years ago. The concentrated phosphorous in their bodies did not have time to dissolve back into the sea water. As a result, the phosphate
