Soil improvers and growing media - Enumeration of enterococci

Abstract

This document specifies a method for the enumeration of enterococci in soil improvers and growing media. This document is applicable to material in solid form (including pre-shaped growing media) and liquid form. This document is applicable to 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 comprise the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If soil improvers and/or growing media do not comprise the highest percentage in the blend, the European Standard for the highest percentage in the blend applies. In case a blend is composed of fertilising products in equal quantity, the user of the standard decides which standard to apply. NOTE 1 A soil improver or 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). NOTE 2 This method has been validated in an interlaboratory study with specific products that were present on the market during the study (Annex C).
