Scope
This standard specifies the extraction and determination methods for the water-soluble phosphorus and effective phosphorus content in compound fertilizers, and also prescribes the calculation method for the percentage of water-soluble phosphorus in effective phosphorus.
This standard applies to phosphorus-containing compound fertilizers (including blended fertilizers), but it does not apply to compound fertilizers synthesized by chemical methods, such as ammonium phosphate, phosphoric acid fertilizer, and potassium dihydrogen phosphate.
