Introduction
This document has been developed to provide guidance for a consistent approach to justify the claims
associated with the use of plant biostimulants in agriculture.
The definition of plant biostimulants to be used in the regulation on fertilizing materials is claims-based.
For this reason, demonstrating that a product is indeed a bona fide plant biostimulant depends on a
demonstration of its effect.
The placing of a plant biostimulant on the market should never be considered to guarantee effectiveness
under all conditions, as many factors can influence the performance of a plant biostimulant in the field.
Plant biostimulants used in agriculture can be applied in multiple ways: on soil, on plant, as seed
treatment, etc. This document is applicable to all application types of plant biostimulants in agriculture.
1 Scope
This document specifies the general principles for justifying the product claims for plant biostimulants.
General principles consist of and define all general parameters, requirements and quality criteria, and
are intended to be applied in order to assess the efficacy of trials used for claim(s) validation as a result
of the use of a plant biostimulant.
This document is aimed primarily at manufacturers, laboratories, researchers, technical centres,
companies that will put the products on the market, notifying authorities, notified bodies, and market
surveillance authorities.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
CEN/TS 17700-5:2022, Plant biostimulants — Claims — Part 5: Determination of availability of confined
nutrients in the soil or rhizosphere
CEN/TS 17724:2022, Plant biostimulants — Terminology
3 Terms and definitions
For the purposes of this document, the terms and definitions given in CEN/TS 17724:2022 and the
following apply.
3.1
plant biostimulant
product stimulating plant nutrition processes independently of the product’s nutrient content with the
sole aim of improving one or more of the following characteristics of the plant or the plant rhizosphere:
• nutrient use efficiency,
• tolerance to abiotic stress,
• quality traits,
• availability of confined nutrient in soil or rhizosphere
3.2
claim
effect(s) of the product that can be asserted on the product label of a plant biostimulant after the
conformity assessment procedure
3.3
general principle
rule defining the crops and quality criteria applicable to all plant biostimulants for carrying out the tests
necessary to justify the claim
3.4
crop
cultivated plant including all components of the plant (above ground parts and below ground parts),
mushrooms, microalgae and macroalgae
3.5
plant nutrient
chemical element used by the plant for growth and development, usually classified as a Primary
Macronutrient, Secondary Macronutrient or Micronutrient in the quantity required by the plant
Note 1 to entry: Carbon, hydrogen, and oxygen are also essential elements for plant growth.
Note 2 to entry: Primary Macronutrients – Nitrogen (N), Phosphorus (P), Potassium (K),
Secondary Macronutrients – Calcium (Ca), Magnesium (Mg), Sodium (Na), Sulphur (S).
Micronutrients – Boron (B), Cobalt (Co), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum
(Mo), Zinc (Zn).
3.6
protected crop
crop cultivation in greenhouses or plastic tunnels with or without specific control of climate conditions
according to the farming practice
EXAMPLE cucumber or tomato cultivation
4 Type of information that can be used to demonstrate efficacy of a claim
4.1 Field and/or protected crop experimental data
Field trials are essential to justify plant biostimulant claims. For some claims, however, the appropriate
field conditions cannot always be easily reached (for example, salt stress or cold stress) in the field.
4.2 Under controlled conditions (e.g.: laboratory data, greenhouse, growth chamber…)
Plant biostimulant claims can be proven (depending on the claim defined in the dedicated Technical
Specification) by data generated under controlled conditions (e.g. greenhouses, growth room, growth
chamber, laboratory data).
4.3 Literature review
Scientific literature can be used as given in Technical Specifications CEN/TS 17700-2:2022 ,
CEN/TS 17700-3:2022 , CEN/TS 17700-4:2022 and CEN/TS 17700-5:2022 to describe analytical
methods and methods used to measure the effect of a product.
Only peer review literature (e.g. referenced by the Scopus/Web of science databases) shall be accepted.
5 General guideline for trials/assays of plant biostimulants
5.1 General
All experiments/trials shall be performed according to the Quality Criteria defined in this document.
5.2 Crop groupings for the performance of plant biostimulant trials
The crop groupings for conduction of plant biostimulant trials are defined in Table 1, except for the
availability of confined nutrients in a soil claim. If the crop is not listed in Table 1, refer to the definition
below to determine the appropriate crop group. Moreover, if the crop does not fit one of these definitions
below, the “a specific crop” rule described in Table 2 will be followed.
• 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 with the ability to cover their stems with suberized cork,
• Vegetables, ornamental and AMP (Aromatic and Medicinal Plant) crops: annual and non-annual
crops usually correlated with seasonality and not included in the broadacre and woody perennial
crops.
