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 (phosphorus pentoxide) and K2O (potassium oxide) content extractable by CaCl2/DTPA;
— the total copper and zinc content;
— 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 [1].
This document is not applicable to preformed materials such as mineral wool slabs and foam slabs.
