This European Standard 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 EN 15960 and EN 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 [2]. The method applies to all fertilizer extracts containing elements in quantities that might interfere with the complexometric determination of magnesium.
