This Technical Specification specifies a method for the determination of the magnesium content in fertilizer extracts using atomic absorption spectrometry (AAS).
This method is applicable to EC fertilizer extracts obtained according to CEN/TS 15960 and CEN/TS 15961, for which a declaration of the total magnesium and/or water soluble magnesium content is required, with the exceptions of the following fertilizers according to [4], Annex I D relating to secondary nutrients:
type 4 (kieserite);
type 5 (magnesium sulfate) and type 5.1 (magnesium sulfate solution);
type 7 (kieserite with potassium sulfate)
to which [4], method 8.8, applies.
NOTE Method 8.8 is covered by CEN/TS 16198 (see Bibliography).
The method applies to all fertilizer extracts containing elements in quantities that might interfere with the complexometric determination of magnesium.
