Scope

This document is applicable to organic, organo-mineral and inorganic fertilizers which contain more than 1 % by mass of organic carbon, other than organic carbon from chelating or complexing agents, nitrification inhibitors, denitrification inhibitors or urease inhibitors, coating agents, urea or calcium cyanamide. This method is intended especially for sample preparation prior to microbiological examinations of e.g. E. coli, Salmonella spp. and enterococci.

If the organic fertilizer, the organo-mineral fertilizer or the inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply.

This document specifies references to the methods for the:
