European foreword
This document (prEN 18300:2026) has been prepared by Technical Committee CEN/TC 223 “Soil
improvers and growing media”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
prEN 18300:2026 (E)
Introduction
Different product functions warrant different product safety, quality and quantity requirements adapted
to their different intended uses. EU fertilizing products have therefore been divided into different product
function categories (PFCs), which are subject to specific safety, quality and quantity requirements, as
specified in the Regulation (EU) 2019/1009 [1].
Soil improvers have been classified as PFC 3, growing media have been classified as PFC 4. The specific
safety and quality requirements in relation to specific parameters are specified in this document, as well
as normative references of the test methods to be used to assess the compliance with the related
requirement.
prEN 18300:2026 (E)
1 Scope
This document refers to methods to be used for the determination of specific parameters in soil
improvers and growing media, but does not contain the methods themselves. The specific parameters in
this document include:
— the cadmium content;
— the lead content;
— the nickel content;
— the chromium (VI) content;
— the mercury content;
— the inorganic arsenic content;
— the phosphonates content;
— the total chromium content;
— the bioavailable nickel content.
This document is applicable to the fertilizing product blends where a blend is a mix of two or more
fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing
media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the
components with the highest percentage in the blend by mass or volume, or in the case of products in
liquid form by dry mass. If the soil improvers and/or growing media are not the components with the
highest percentage in the blend, the European Standard relevant to the component with the highest
percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal
quantities, the user of the standard decides which standard to apply.
NOTE A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix
of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
