General Information
Relations
Overview
EN 17700-2:2024 (CEN) provides structured guidance to justify claims that a plant biostimulant improves nutrient use efficiency. The standard complements EN 17700-1:2024 (general principles) and EN 17724:2024 (terminology), and is aimed at manufacturers, laboratories, researchers, technical centres, notified bodies and market surveillance authorities. Its objective is to increase transparency and reproducibility of claim substantiation so products placed on the market can be assessed consistently.
Key Topics
- Scope and audience: Practical guidance for all application types (soil, foliar, seed treatments) and stakeholders involved in placing plant biostimulants on the market.
- Terminology: Clarifies key terms used in claims such as nutrient use efficiency, available nutrient, uptake efficiency, utilization efficiency and plant nutrient.
- Claim wording: Requires clear labelling that specifies the nutrient(s) and target crop(s) for which the effect has been demonstrated (for example, "improves nitrogen use efficiency in wheat").
- Assessment indices: Recommends agronomic indices to validate claims. Common indices described include:
- Ie (Internal utilization efficiency) - relationship of yield to nutrient in plant biomass
- Pfp (Partial factor productivity) - yield per unit nutrient supplied
- Ne (Nutrient export) - nutrient content in harvested part
- Re (Apparent crop recovery efficiency), Pe (Physiological efficiency) and Ae (Agronomic efficiency) - indices that separate recovery, physiological transformation and combined agronomic response
- Trial specifications and controls: Details the minimum trial treatments and control structure required to calculate Re, Pe and Ae, with examples showing fertilized and unfertilized controls with and without biostimulant application.
Applications
EN 17700-2:2024 supports practical activities across the biostimulant value chain:
- Product development: design trials that demonstrate specific nutrient efficiency claims using standardized indices.
- Regulatory dossiers: assemble evidence aligned with the Fertilising Products Regulation (EU) 2019/1009 and national notification procedures.
- Laboratory and trial protocols: harmonize measurement approaches (U, Y, F, C) to generate comparable results across sites and seasons.
- Market surveillance: provide clear evidence for auditing claim substantiation and labelling.
Benefits include improved consistency of claims, stronger confidence for farmers and buyers, and clearer pathways for commercialization.
Related Standards

- EN 17724:2024 - Plant biostimulants - Terminology
- Relevant EU legislation: Regulation (EU) 2019/1009 (Fertilising Products Regulation)
For implementation, organizations should follow the quality criteria and trial-control definitions in EN 17700-1:2024 and use the indices and trial examples in EN 17700-2:2024 to substantiate nutrient use efficiency claims consistently.

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.
WARNING — Persons using this document should be familiar with normal laboratory practice. This
document does not purport to address all of the safety problems, if any, associated with its use. It is the
responsibility of the user to establish appropriate safety and health practices and to ensure compliance
with any national rules.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this document be
carried out by suitably trained staff.
