PD CEN/TS 17731:2022

What is PD CEN/TS 17731 – Determination of parameters in growing media about? 

PD CEN/TS 17731 is a standard that covers the determination of parameters in growing media, ensuring the quality, potency and performance in agricultural and gardening applications.
PD CEN/TS 17731 gives an overview of relevant methods for the determination of specific parameters in growing media, including:

• Electrical conductivity and pH
• Dry matter
• Nitrogen, P2O5 (phosphorus pentoxide) and K2O (potassium oxide) content extractable by CaCl2/DTPA
• Total copper and zinc content and the quantity

PD CEN/TS 17731 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].

PD CEN/TS 17731 is not applicable to preformed materials such as mineral wool slabs and foam slabs.
