  Phosphorus (P) is an essential primary nutrient in the ‘diet’ of all living things – micro-organisms, plants, animals and humans – as it is an essential component of their genetic material (DNA); of phospho-lipids that form membrane structures; and it is the basis of energy transfer in cellular metabolism (ADP/ATP interconversion). As such it […]
