M/051 - Chelated fertilizers
Study and standardization remit assigned to the CEN concerning the updating of the methods of analysing the chelated trace-element content of fertilizers
Mandate M/051 assigns CEN the task of studying and updating the analytical methods for determining the chelated trace-element content in fertilizers. The objective is to standardize these methods to ensure consistency and reliability in the assessment of chelated fertilizers. This mandate supports the harmonization of testing procedures within the industry, facilitating trade and regulatory compliance across the EU. The decision pertains to the approval or disapproval of this standardization remit, as documented in resolution CEN/BT C141/1994.
Purpose
The mandate M/051 concerns the study and updating of standardized methods for analyzing the chelated trace-element content in fertilizers. It aims to ensure that these analytical methods remain accurate and reflect current scientific and technical knowledge.
Standardisation request
The European Committee for Standardisation (CEN) is requested to review and update existing standards related to the analysis of chelated trace elements in fertilizers. This includes evaluating current analytical procedures and proposing harmonized, reliable testing methods.
Expected deliverables
- A comprehensive study on current methods for analyzing chelated trace-element content in fertilizers.
- Updated or new standardized analytical methods ensuring consistency and accuracy in testing chelated trace elements.
- Documentation supporting the revised standards to facilitate their implementation across the EU.
Context
Chelated fertilizers contain trace elements combined with organic molecules to enhance nutrient availability. Accurate analysis of these trace elements is essential for quality control, regulatory compliance, and environmental protection. The mandate aligns with broader EU efforts to maintain high standards in agricultural inputs and supports the harmonization of testing methods across member states. The resolution reference CEN/BT C141/1994 indicates the formal approval process within CEN for this mandate.
This mandate covers the study and standardization of methods for analyzing the chelated trace-element content in fertilizers. It focuses on updating analytical techniques to ensure consistent assessment of chelated fertilizers used in agriculture.
General Information
This standard defines a method for determination of the chelated trace element content and the chelated fraction of the trace elements (micronutrients) cobalt, copper, iron, manganese, and zinc in fertilizers. This method applies to fertilizers, covered by Directive 89/530/EEC, containing one or more of the trace elements cobalt, copper, iron, manganese, and zinc, chelated by one or more chelating agents of the group of the polyamino polycarboxylic acids.

This method describes the procedure for the ion chromatographic determination of the total amount of each individual chelating agent EDTA, HEDTA, and DTPA in fertilizers, containing one or more of these substances. The method allows the identification and the determination of the total water soluble fraction of each of these chelating agents. It does not allow to distinguish between the free form and the metal bound form of the chelating agent.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/051 is a European Standardization Mandate titled "Study and standardization remit assigned to the CEN concerning the updating of the methods of analysing the chelated trace-element content of fertilizers". Study and standardization remit assigned to the CEN concerning the updating of the methods of analysing the chelated trace-element content of fertilizers There are 4 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
