This document provides an overview of relevant methods for the determination of specific parameters in growing media, including:
— electrical conductivity;
— chloride;
— pH;
— dry matter;
— nitrogen, P2O5 (phosphorus pentoxide) and K2O (potassium oxide) content extractable by CaCl2/DTPA;
— copper and zinc content;
— quantity.
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 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)
