Describes a method for the determination of magnesium in fertilizer extracts by complexometry.

This European Standard specifies a method for the determination of magnesium in fertilizer extracts by complexometry. The method is applicable to the following EC fertilizer extracts for which the determination of total magnesium and/or water-soluble magnesium is provided for according to the Regulation (EC) No 2003/2003, Annex I [3]: - fertilizers listed in [3], Annex I: straight nitrogenous fertilizers, type 1b + 1c (calcium magnesium nitrate), type 7 (magnesium sulfonitrate), type 8 (nitrogenous fertilizers with magnesium) and straight potassic fertilizers, type 2 (enriched kainite), type 4 (potassium chloride containing magnesium), type 6 (potassium sulfate containing magnesium salt); - fertilizers listed in [3], Annex I D relating to secondary nutrients.
