biostimulants”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2025, and conflicting national standards shall be
withdrawn at the latest by May 2025.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TS 17724:2022.
— addition of new terms and definitions and revision of others;

This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,

Introduction
The European Committee for Standardization (CEN) was requested by the European Commission (EC) to
draft European Standards or European Standardization deliverables to support the implementation of
Regulation (EU) 2019/1009 of 5 June 2019 [1] laying down rules on the making available on the market
of EU fertilising products (“FPR” or “Fertilising Products Regulation”).
This standardization request, presented as SR M/564 and relevant amendments, also contributes to the
Communication on “Innovating for Sustainable Growth: A Bio economy for Europe”. The interest in plant
biostimulants has increased significantly in Europe as a valuable tool to use in agriculture.
Standardization was identified as having an important role in order to promote the use of biostimulants.
The work of CEN/TC 455 seeks to improve the reliability of the supply chain, thereby improving the
confidence of farmers, industry, and consumers in biostimulants, and will promote and support
commercialisation of the European biostimulant industry.

— quality traits,
— availability of confined nutrient in soil or rhizosphere
3.1.1.9

experimental design, protocol and parameters to prove the consistency of a result
Note 1 to entry: Trials done in controlled conditions are excluded.
Note 2 to entry: It can be conducted in different locations and/or over a number of consecutive years, as long as it

stress, relative water content, heat shock proteins, electrolyte leakage, chlorophyll fluorescence, lipid peroxides.
Note 1 to entry: A subdivision of the three traits is seen below:
— biochemical traits (antioxidants, lipid peroxidation, reduction in reactive oxygen species (ROS), reduction in
free radicals),
— molecular traits (genes, transcription factors, metabolic pathways related to abiotic stress),
— physiological traits: electrolyte leakage, relative water content, reduced stress symptoms.
3.1.2
nutrient use efficiency
measure of a plant’s ability to acquire and utilize nutrients from the environment for a desired outcome
based on (a) nutrient availability (b) uptake efficiency and/or (c) utilization efficiency
Note 1 to entry: Nutrient use efficiency is a complex trait: it depends on the ability of the plant to take up the
nutrients from the soil or growing media and the fertilizer applied, but also on nutrient transport, storage,
mobilization, and use within the plant, among other factors.
3.1.2.1
chelated plant nutrient
complexed plant nutrient
composition based on an inorganic form of the plant nutrient and a chelating or complexing agent,
resulting in a product that enhances the nutrient availability to plants

3.1.2.2
