| Resumen: | This document specifies a method for the enumeration of enterococci in microbial and non-microbial plant biostimulants. This document specifies a colony-count technique on a selective medium (Slanetz-Bartley agar) with confirmation on Bile Esculin Azide agar. This document is applicable to all formulations of microbial and non-microbial plant biostimulants in liquid or solid form. This document is not applicable to other fertilizing products. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Plant Biostimulants, and where the following category Plant Biostimulants is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations , the user decides which standard to apply. |
