Overview of Phosphate

WebPhosphinates or hypophosphites are a class of phosphorus compounds conceptually based on the structure of hypophosphorous acid. IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g. sodium hypophosphite ), while phosphinate typically refers to organophosphorus species. WebPhosphate Retention (PR) is a measure used to describe the phosphorus (P) immobilisation potential of a soil. The term Anion Storage Capacity (ASC) is the modern term for this feature of soil science – adopted because similar effects are seen with sulphur (S) as another essential plant nutrient. An ASC test should be included with any initial ... irm hermann todesursache
