Fertilizers, liming materials and inhibitors - Determination of the chloride content

Publication date:   Aug 13, 2026

Scope

This document specifies references to methods for the determination of the chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers, liming materials and inhibitors.
This document is applicable to fertilizing product blends where the blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If 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 only of inorganic products, the European Standard for inorganic fertilizers applies.
NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
