Fertilizers - Extraction of water-soluble calcium, magnesium, sodium and sulfur in the form of sulfates

This European Standard specifies a method for the extraction of water-soluble calcium, magnesium, sodium and sulfur (in the form of sulfates), so that the same extract can be used for the determination of each nutrient required.
The method is solely applicable to fertilizers listed in Regulation (EC) 2003/2003, Annex I [2]), for which a declaration of the water-soluble calcium, magnesium, sodium, and sulfur (in the form of sulfates) is provided for in this Regulation.

Düngemittel - Extraktion von wasserlöslichem Calcium, Magnesium und Natrium sowie von Schwefel in Form von Sulfat

Diese Europäische Norm legt ein Verfahren zur Extraktion von wasserlöslichem Calcium, Magnesium, Natrium und Schwefel (in Form von Sulfat) fest, so dass derselbe Extrakt für die Bestimmung jedes erforderlichen Nährstoffes verwendet werden kann.
Das Verfahren gilt ausschließlich für in der Verordnung (EG) 2003/2003, Anhang I [2] aufgeführte Düngemittel, für die die Angabe des wasserlöslichen Calciums, Magnesiums, Natriums und Schwefels (in Form von Sulfat) vorgeschrieben ist.
