CEN/TS 17782:2022 (E)
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 consists 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. The EU fertilizing products
containing chelates remain stable for at least three days in a solution having any pH within the range
declared as guaranteeing acceptable stability. Metal chelates can be used in agriculture directly to soils,
in nutrient solution in fertirrigation or soilless culture and in solution for foliar application. Tap water
is a good model for interaction with chelates since it contains calcium and magnesium that may react
chemically with the metal chelates. Composition described for CIPAC (Collaborative International
Pesticides Analytical Council) standard tap water D is a good representative of a tap water of medium
hardness and will be used in this standard to determine the stability for at least three days of
micronutrient chelates at any specific pHs.
This document defines a test method to check the chelate stability in solution, using as a model the
interaction in a reference tap water similar to the CIPAC D.
