Fertilizers - Treatment with a cation exchange resin for the determination of the chelated micro-nutrient content and of the chelated fraction of micro-nutrients
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.
Düngemittel - Behandlung mit einem Kationenaustauscherharz zur Bestimmung des chelatisierten Spurennährstoffgehaltes und des chelatgebundenen Anteils von Spurennährstoffen
Diese Norm legt ein Verfahren zur Bestimmung des chelatgebundenen Spurennährstoffgehaltes und der chelatgebundenen Fraktion der Spurennährstoffe (Mikronährstoffe) Kobalt, Kupfer, Eisen, Mangan, und Zink in Düngemitteln fest. Dieses Verfahren gilt für Düngemittel nach Richtlinie 89/530/EWG, die einen oder mehrere der Spurennährstoffe Kobalt, Kupfer, Eisen, Mangan und Zink enthalten und durch einen oder mehrere Chelatbildner aus der Gruppe der Polyaminopolycarboxylsäuren.

Overview
EN 13366:2001 (CEN) specifies a laboratory method for determining the chelated micro‑nutrient content and the chelated fraction of micronutrients in fertilizers. The method uses treatment with a cation exchange resin to separate chelated from non‑chelated forms and is applicable to fertilizers covered by Directive 89/530/EEC that contain one or more of the trace elements cobalt, copper, iron, manganese, and zinc chelated by polyamino polycarboxylic acids.
Key Topics and Requirements
- Scope and applicability: Applies to fertilizers containing Co, Cu, Fe, Mn and Zn chelated by members of the polyamino polycarboxylic acid family and falling under the Directive 89/530/EEC classification.
- Analytical principle: Use of a cation exchange resin to separate chelated micro‑nutrients from exchangeable (non‑chelated) forms prior to quantitative determination.
- Analytes covered: Cobalt (Co), Copper (Cu), Iron (Fe), Manganese (Mn), Zinc (Zn) - determination of total chelated content and the chelated fraction of each element.
- Method outcome: Yields values for the amount of chelated trace elements and the proportion of each trace element present as chelate versus non‑chelate.
- Reporting: Results are used to characterise chelation status of micronutrients in fertilizer products for regulatory compliance and product labelling.
Applications
- Fertilizer manufacturers: Quality control of micronutrient formulations, verification of chelation claims, and batch testing.
- Analytical laboratories: Routine testing and certification of fertilizers to determine chelated micronutrient content.
- Regulatory authorities: Enforcement of Directive 89/530/EEC and verification that marketed fertilizers meet declared chelated micronutrient specifications.
- R&D and product development: Formulation development where chelation behavior affects micronutrient availability and stability.
Benefits
- Provides a standardized procedure for assessing chelated micro‑nutrients, improving comparability of test results across laboratories.
- Supports accurate product labelling and regulatory compliance for fertilizers containing chelated trace elements.
Related Standards
- EN 13366:2001 is part of the CEN family of fertilizer testing standards and is used alongside other European fertilizer standards and regulatory documents such as Directive 89/530/EEC. For complete conformity and testing programs, consult additional CEN fertilizer standards and national transpositions.
