Plant biostimulants - Determination of phosphonates
This document specifies a method for the extraction and determination of phosphonates (P-PO3) in plant biostimulants using ion chromatography and conductivity detection (IC-CD).
This document is applicable to the fertilizing product blends belonging to PFC 7 where the EU fertilising product plant biostimulant contained in the blend represents the highest % by mass in the blend. In case of equal shares, the user may apply either this or the standard(s) applicable to the other component product(s).
Biostimulanzien für die pflanzliche Anwendung - Bestimmung von Phosphonaten
Dieses Dokument legt ein Verfahren zur Extraktion und Bestimmung von Phosphonaten (P PO3) in Pflanzen-Biostimulanzien mit Ionenchromatographie und Leitfähigkeitsnachweis (IC CD) fest.
Dieses Dokument ist für Düngeproduktmischungen anwendbar, die zur PFC 7 gehören und bei denen das in der Mischung enthaltene EU Düngeprodukt Pflanzen-Biostimulans den größten Massenanteil in % in der Mischung ausmacht. Im Fall von gleich großen Anteilen darf der Anwender entweder die vorliegende Norm oder die für den/die anderen Bestandteil(e) anwendbare(n) Norm(en) verwenden.
Biostimulants des végétaux - Dosage des phosphonates
Le présent document spécifie une méthode d’extraction et de dosage des phosphonates (P-PO3) dans les biostimulants des végétaux par chromatographie ionique et détection conductimétrique (IC-CD).
Le présent document est applicable aux mélanges de fertilisants appartenant à la catégorie PFC 7, dans lesquels le fertilisant UE biostimulant des végétaux contenu dans le mélange représente le % le plus élevé en masse dans le mélange. Dans le cas où les proportions sont égales, l’utilisateur peut appliquer la présente norme ou la ou les normes applicables aux autres produits constituants.
