scope:
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.
