European foreword

This document (FprCEN/TS 17704:2021) has been prepared by the Technical Committee CEN/TC 455

“Plant biostimulants”, the secretariat of which is held by AFNOR.
This document is currently submitted to the Vote on TS.

This document has been prepared under a Standardization Request given to CEN by the European

Commission and the European Free Trade Association.

Introduction

This document was prepared by the experts of CEN/TC 455 ‘Plant Biostimulants’. 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 laying down rules on the making available on the market of

EU fertilising products (“FPR” or “Fertilising Products Regulation”).

This request, presented as SR M/564, also contributes to the Communication on “Innovating for

Sustainable Growth: A Bio economy for Europe”. The Working Group 4 “Other safety parameters”, was

created to develop a work program as part of this Request. The technical committee CEN/TC 455 ‘Plant

Biostimulants’ was established to carry out the work program that will prepare a series of standards. The

interest in 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. The preparation of this document is based on

a standardization request to CEN by the European Commission and the European Free Trade Association

(Mandate M/564) concerning the modernization of methods of analysis of fertilizers within the

framework of Regulation (EU) 2019/1009 of the European Parliament and of the Council.

In case of the analysis of plant biostimulants, water is usually not considered a part of the sample and

results are generally related to dry matter, which can be calculated by determining the dry residue (dry

matter fraction).

This document is also applicable to the blends of fertilizing products where plant biostimulants are the

main part of the blend. Otherwise, the Technical Specification for the main part of the blend apply.

WARNING – Persons using this Technical specification should be familiar with usual laboratory

practice. This document does not purport to address all of the safety issues, if any, associated with

its use. It is the responsibility of the user to establish appropriate health and safety practices and

to ensure compliance with any national regulatory conditions.

IMPORTANT – It is absolutely essential that tests conducted according to this document are

carried out by suitably trained staff.
