— Part 2: Nutrient use efficiency resulting from the use of a plant biostimulant;

— Part 3: Tolerance to abiotic stress resulting from the use of a plant biostimulant;

— Part 4: Determination of quality traits resulting from the use of a plant biostimulant;

— Part 5: Determination of availability of confined nutrient in the soil or rhizosphere.

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 may 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 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:— , Plant biostimulants - Claims - Part 5: Determination of availability of confined

nutrients in the soil or rhizosphere

3 Terms and definitions

For the purposes of this document, the terms and definitions given in CEN/TS 17724:— 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 could 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 – Sulphur (S), Calcium (Ca), Magnesium (Mg), Sodium (Na),

Micronutrients – Iron (Fe), Molybdenum (Mo), Boron (B), Copper (Cu), Manganese (Mn), Zinc (Zn), Cobalt (Co).

3.6
protected crop

crop cultivation in greenhouses or plastic tunnels with or without specific control of climate conditions

according to the farming practice (for example: cucumbers/ tomatoes 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:— , CEN/TS 17700-

4 5

3:— , CEN/TS 17700-4:— and CEN/TS 17700-5:— to describe methods used to measure the effect of

the product and analytical methodologies.

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 “specific cultures” rules 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.
