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.
This document has been developed to provide guidance for a consistent approach to justify the claims
associated with the use of plant biostimulants.
The definition of plant biostimulants in Regulation (EU) 2019/1009 [1] is claims-based. For this reason,
demonstrating that a product is indeed a bona fide plant biostimulant depends on a demonstration of its
function.
The placement of a plant biostimulant on the market does not guarantee effectiveness under all
conditions, as many factors can influence the performance of a plant biostimulant in the field.
Plant biostimulants can be applied in multiple ways: to the soil, on plants, as seed treatment, etc.
This document is applicable to all application types of plant biostimulants.

1 Scope
This document specifies the general principles for justifying the product claims for plant biostimulants.
It is applicable to all claims and all types of application of plant biostimulants.
General principles define all general parameters, requirements and quality criteria to be applied in order
to assess trials conducted to validate the claim(s) associated with the use of a plant biostimulant.
This document is aimed primarily at manufacturers, laboratories, researchers, technical centres and
companies that intend to place plant biostimulants on the market, as well as notifying authorities, notified
bodies, and market surveillance authorities.

[SOURCE: EN 17724:2024, 3.1.1.5]
4 Trials conditions to demonstrate claim(s)
Trials carried out according to farming practices (open field or protected crop conditions) are essential
to demonstrate plant biostimulant claims.
For some claims, however, field conditions cannot always be easily met (e.g. salt stress, cold stress, root
measurements, availability of confined nutrients in the soil, etc.). In this case, plant biostimulant claims
can be demonstrated under controlled conditions. The petitioner shall explain why the demonstration of
the claim cannot be conducted under field conditions.
Analytical methods and methods used to measure the effect of a product can also be taken from scientific
literature as specified in EN 17700-2:2024 [2], EN 17700-3:2024 [3], EN 17700-4:2024 [4] and
EN 17700-5:2024.
5 General guidelines for trials of plant biostimulants
5.1 General
All trials/assays shall be performed according to the quality criteria specified in this document.
5.2 Crop groupings for the performance of plant biostimulant trials
For trials carried out with plants, the crop groupings are specified in Table 1. These crop groupings do
not apply to soil claims related to the availability of confined nutrients in the soil or rhizosphere. If the
crop tested is not specified in Table 1, refer to the definition below to determine the appropriate crop
grouping.
— Broadacre crops (combinable and processing products): annual and non-annual crops usually
characterized by being grown in large extensions, harvested via combiners or industrial harvesters,
with the aim of obtaining vegetative organs, roots, tubers and/or seeds/grains.
— Woody perennials: non-annual crops that cover their stems with suberized cork.
— Vegetables, ornamental and aromatic and medicinal plants (AMP): annual and non-annual crops
usually associated with seasonality and not included in the broadacre and woody perennial crops.
