Phosphate: Its Importance in Water and Its Measurement

Phosphorus in the form of phosphate (PO 4-3) is an essential plant nutrient. Phosphate in the form of "superphosphate"--calcium hydrogen phosphates [CaHPO 4 and/or Ca(H 2 PO 4) 2]--is a major component of many fertilizers. Excessive concentrations of soluble reactive phosphate (SRP, a.k.a. soluble reactive phosphorus) are often responsible
