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.

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 to take up the nutrients from
the soil, medium, fertilizers… but also on transport, storage, mobi
