Fertilizers and soil conditioners. Determination of water-soluble potassium content. Potassium tetraphenylborate gravimetric method Ingestion-build-48068 test methods and performance requirements1 Scope This International Standard specifies a gravimetric method for the determination of the water soluble potassium content of test solutions of fertilizers. It is suitable for use in arbitration and for reference purposes. This International Standard is applicable to those fertilizers containing more than 1,0 % K2O or equivalent amount of K content.
