Overview

prEN 17753: Inorganic fertilizers – Determination of specific contaminants is a draft European Standard developed by CEN/TC 260. This standard specifies references to methods for determining the content of certain contaminants-comprising mercury, cadmium, nickel, copper, zinc, arsenic, lead, chromium(VI), biuret, perchlorate, total chromium, and phosphonates-in inorganic fertilizers and relevant fertilizer blends. The standard is designed to support conformity with the contaminant safety requirements outlined in Regulation (EU) 2019/1009 for EU fertilizing products, promoting both environmental safety and product quality.

Key Topics

1. Covered Contaminants

  • Heavy metals: mercury, cadmium, nickel, copper, zinc, arsenic, lead, total chromium, chromium(VI)
  • Organic/inorganic substances: biuret, perchlorate, phosphonates

2. Applicability to Fertilizer Blends

  • Applies to blends containing at least two components (e.g., fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants).
  • If the inorganic fertilizer fraction is the largest part of the blend, prEN 17753 applies. If not, the standard for the most prevalent component is used.
  • For chromium(VI) and biuret, the standard applies when any blend component contains organic matter.

3. Analytical Methods

  • Specifies robust, referenced methods such as ICP-AES, atomic absorption spectrometry, photometry, ion chromatography, and HPLC, depending on the contaminant.
  • Emphasizes that sample preparation and extraction methods must follow referenced standards to ensure accurate contaminant quantification.

4. Compliance and Market Access

  • Supports manufacturers' compliance with EU regulations, specifically Regulation (EU) 2019/1009, relating to the market placement of fertilizers.
  • Adherence ensures products meet essential safety and quality requirements, facilitating access to the EU market.

Applications

Fertilizer Manufacturers and Blenders

  • Use the standard to test finished products and raw materials for specific contaminants, ensuring regulatory compliance.
  • Apply referenced methods when developing new inorganic fertilizer blends or reformulating existing products to verify safety.

Testing Laboratories

  • Reference the prescribed analytical methods for mercury, cadmium, and other contaminants in fertilizer quality assurance and external testing services.
  • Validate the presence and concentration of regulated substances to avoid legal or commercial setbacks.

Regulatory Authorities and Inspectors

  • Assess compliance of inorganic fertilizers and blends on the market through standardized testing protocols.
  • Aid in the certification and approval process for market release.

Agricultural Sector

  • Ensures the fertilizers applied in agriculture do not introduce hazardous substances, supporting sustainable farming and environmental protection.
  • Contributes to the safe application of soil amendments and plant nutrients.

Practical Value

Complying with prEN 17753 minimizes the risk of environmental contamination and meets regulatory demands for product safety. The standard enables reliable, repeatable contaminant testing, builds trust with consumers and regulators, and streamlines access to the EU fertilizer market for manufacturers. As environmental and regulatory requirements grow more stringent, adoption of prEN 17753 and referenced EU standards is essential for ensuring product integrity and sustainability across the inorganic fertilizer industry.

Introduction
Regulation (EU) 2019/1009 [3] lays down the rules on the making available on the market of EU
fertilizing products and the specific safety and quality requirements for the defined product function
categories (PFCs). Inorganic fertilizers have been classified into PFC 1(C).
The specific safety and quality requirements in relation to specific contaminants (i.e. the mercury,
cadmium, nickel, copper, zinc, arsenic, lead, chromium VI, biuret, perchlorate and total chromium
content) are defined in this document as well as normative references of the test methods to be used in
order to measure the compliance with the related requirement in the Regulation (EU) 2019/1009 [3].
The definition of phosphonates is not clearly stated in Regulation (EU) 2019/1009 [3] and to avoid any
misunderstanding, the results are expressed as a content of phosphorus (P) bound in the form of free
water-soluble phosphonates (P-PO ).
1 Scope
This document specifies references to methods for the determination of the following contaminants:
mercury, cadmium, nickel, copper, zinc, arsenic, lead, chromium(VI), biuret, perchlorate, total chromium
and phosphonates content in inorganic fertilizers.
For the mercury, cadmium, nickel, copper, zinc, arsenic, lead, perchlorate and total chromium content:
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the
following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant
biostimulants, and where the following category: inorganic fertilizers is the highest % in the blend by
mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the
blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is
composed of components in equal quantity, the user decides which standard to apply.
For the chromium(VI) and biuret content: This document is applicable to the fertilizing products blends
where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil
improvers, growing media, inhibitors, plant biostimulants, and where organic matter is present in at least
one of the products in the blend. In case a fertilizing product blend is composed only of inorganic
products, the European Standard for inorganic fertilizers applies. Variations in analytical methods for
fertilizing product blends can lead to differing results as some components or matrix interactions can
affect the outcome. Validation procedures have shown that developed standard methods are robust and
reliable across diverse product compositions, but possible interferences and unexpected results when
analysing fertilizing product blends are possible.
An overview of the references to methods for the determination of the specific contaminants is given in
Table 1.
NOTE 1 The determination of copper and zinc in inorganic fertilizers as micronutrients is covered by
prEN 17754.
NOTE 2 The determination of copper in ammonium nitrate fertilizers of high nitrogen content is covered by
CEN/TS 17751.
