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.---------------------- Page: 5 ----------------------

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.---------------------- Page: 6 ----------------------
