Inorganic fertilizers - Determination of extracted phosphorus P2O5

This document specifies a method for the determination of phosphorus in fertilizer extracts.
The method is applicable to all extracts of fertilizers for the determination of the different forms of phosphorus as phosphorus soluble in mineral acids, water-soluble phosphorus, phosphorus soluble in solutions of ammonium citrate, phosphorus soluble in 2 % citric acid and phosphorus soluble in 2 % formic acid.

Anorganische Düngemittel - Bestimmung des Gehalts an extrahiertem Phosphor P2O5

Dieses Dokument legt ein Verfahren zur Bestimmung von Phosphor in Düngemittelextrakten fest.
Das Verfahren ist auf alle Düngemittelextrakte anwendbar, die zur Bestimmung von Phosphor in seinen verschiedenen Formen dienen, wie z. B. in Mineralsäuren löslicher Phosphor, wasserlöslicher Phosphor, Phosphor löslich in Ammoniumcitrat-Lösungen verschiedener Konzentration, Phosphor löslich in 2%iger Citronensäure und Phosphor löslich in 2%iger Ameisensäure.
Das Verfahren wurde nur für anorganische Düngemittel validiert, kann aber bei Verwendung geeigneter Extraktionsverfahren auf jeden Phosphor in den Extrakten angewendet werden.

Engrais inorganiques - Dosage du phosphore extrait P2O5

Le présent document spécifie une méthode de dosage du phosphore dans des extraits d’engrais.
La méthode est applicable à tous les extraits d’engrais pour le dosage des différentes formes de phosphore telles que le phosphore soluble dans les acides minéraux, dans l’eau, dans des solutions de citrate d’ammonium, dans l’acide citrique à 2 % et dans l’acide formique à 2 %.
La méthode a uniquement été validée pour les engrais inorganiques, mais elle peut être applicable à tout phosphore extrait si des méthodes d’extraction correctes sont utilisées.
