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.

Introduction
Micronutrients are considered to be, in plant nutrition, a number of elements known to be needed in
small amounts for proper plant growth and development. The most common micronutrient metals are
Iron (Fe), Manganese (Mn), Cobalt (Co), Copper (Cu) and Zinc (Zn).
An EU fertilizing product shall consist solely of component materials complying with the requirements
for one or more of the component material categories (CMCs). CMC 1 corresponds with the virgin
material substances and mixtures.
If a micronutrient fertilizing product contains a substance, or one of the substances in the mixture,
which is intended to enhance the long-term availability to plants of micronutrients in the EU fertilizing
product, that substance is either a chelating agent or a complexing agent. According to Regulation (EU)
2019/1009 [2], EU fertilizing products containing complexed micronutrients shall remain stable in
water solution at pH 6 and pH 7 for at least one day.
This document defines a test method to check the micronutrient complex stability in solution at pH 6
and pH 7.
