Organo-mineral fertilizers - Determination of the fraction of complexed micronutrients

This document specifies a general method for the determination of the micronutrients complexed by complexing agents in organo-mineral fertilizers. The method allows the determination of the total concentration of each complexed micronutrient in complexes after subtraction of the chelated micro-nutrients content, but it does not identify the individual complexing agents.
This procedure concerns EU organo-mineral fertilizing products which contain complexed micro-nutrients covered by Regulation (EU) 2019/1009 [6]. The method is applicable to a mass fraction of the metal complexed of at least 0,07 %, 0,006 % and 0,035 % of Fe, Mn and Zn respectively (see [7]). A lower limit of quantification has not been established for Cu and Co.

Organisch-mineralische Düngemittel - Bestimmung des Anteils an komplexierten Spurennährstoffen

Dieses Dokument legt ein allgemeines Verfahren zur Bestimmung von in organisch-mineralischen Düngemitteln durch Komplexbildner komplexierte Spurennährstoffen fest. Dieses Verfahren ermöglicht die Bestimmung der Gesamtkonzentration jedes komplexierten Spurennährstoffs in Komplexen nach Subtraktion des Gehalts an chelatisierten Spurennährstoffen. Es ermöglicht jedoch nicht die Bestimmung des jeweiligen Komplexbildners.
Dieses Verfahren bezieht sich auf organisch-mineralische Düngeprodukte der EU, die komplexierte Spurennährstoffe enthalten, die unter die Verordnung (EU) 2019/1009 fallen [6]. Das Verfahren ist bei einem Massenanteil des komplexierten Metalls von mindestens 0,07 %, 0,006 % und 0,035 % an Fe, Mn bzw. Zn anwendbar (siehe [7]). Eine niedrigere Bestimmungsgrenze wurde für Cu und Co nicht ermittelt.

Engrais organo-minéraux - Détermination de la fraction d'oligo-éléments complexés

Le présent document spécifie une méthode générale de dosage des oligo-éléments complexés par des agents complexants dans les engrais organo-minéraux. La méthode permet de déterminer la concentration totale de chaque oligo-élément complexé dans des complexes, après avoir soustrait la teneur en oligo-éléments chélatés, mais elle ne permet pas d’identifier les agents complexants individuels.
Ce mode opératoire concerne les fertilisants organo-minéraux UE qui contiennent des oligo-éléments complexés couverts par le Règlement (UE) 2019/1009 [6]. La méthode est applicable à une fraction massique du métal complexé d’au moins 0,07 %, 0,006 % et 0,035 % de Fe, Mn et Zn respectivement (voir [7]). Une limite de quantification plus basse n’a pas été établie pour le Cu et le Co.

Organsko-mineralna gnojila - Določanje deleža kompleksiranih mikrohranil

Ta dokument določa splošno metodo za določevanje mikrohranil, kompleksiranih s sredstvi za kompleksiranje v organsko-mineralnih gnojilih. Metoda omogoča določanje skupne koncentracije vsakega kompleksiranega mikrohranila v kompleksih po odštetju vsebnosti kelatiranih mikrohranil, vendar ne identificira posameznih sredstev za kompleksiranje.
Ta postopek se navezuje na organsko-mineralna sredstva za gnojenje EU, ki vsebujejo kompleksirana mikrohranila, zajeta v Uredbi (EU) 2019/1009 [6]. Metoda se uporablja za masni delež kompleksirane kovine najmanj 0,07 %, 0,006 % oziroma 0,035 % Fe, Mn oziroma Zn (glej točko [7]). Spodnja meja kvantifikacije za Cu in Co ni določena.

This Technical Specification (CEN/TS) was approved by CEN on 21 February 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.
