Growing media - Determination of specific parameters

This document provides an overview of relevant methods for the determination of specific parameters in growing media, including:
-   the electrical conductivity;
-   the pH;
-   dry matter;
-   the nitrogen, P2O5 and K2O content extractable by CaCl2/DTPA;

-   the quantity.
This document is applicable to EU fertilizing products classified as PFC 4 and PFC 7 as long as the main function of the EU fertilizing product is classified as PFC 4 of Regulation (EU) 2019/1009 [2].
This document is not applicable to preformed materials such as mineral wool slabs and foam slabs.

Kultursubstrate - Bestimmung spezifischer Parameter

Dieses Dokument gibt ein Überblick über relevante Verfahren zur Bestimmung spezifischer Parameter von Kultursubstraten, darunter:
-   die elektrische Leitfähigkeit;
-   der pH Wert;
-   die Trockensubstanz;

-   der Gesamt-Kupfer- und Zinkgehalt;
-   die Menge.
Dieses Dokument ist anzuwenden für EU Düngeprodukte der Kategorien PFC 4 und PFC 7, vorausgesetzt, die Hauptfunktion des EU Düngeprodukts entspricht der Kategorie PFC 4 aus Verordnung (EU) 2019/1009 [2].
Dieses Dokument ist nicht anzuwenden für vorgeformte Materialien wie etwa Platten aus Mineralwolle oder Schaumstoff.

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 should each be subject to specific safety and quality requirements, as

specified in the Regulation (EC) No 2019/1009 [2].

Growing media have been classified as PFC 4, as specified in the Regulation (EC) No 2019/1009 [2]. The

specific safety, quality and quantity requirements in relation to some of the specific parameters (i.e. the
