Organic and organo-mineral fertilizers - Determination of the dry matter content; German and English version prEN 17773:2026
Abstract
This document specifies the procedure for the determination and calculation of the dry matter content of organic and organo-mineral fertilizers for which the results of the performed analysis are to be calculated to the dry matter content basis. This document is applicable and validated for several types of matrices as indicated in Annex A. This document is applicable to the component materials "by-products", "thermal oxidation materials and derivatives", or "recovered high-purity materials", when used as components of fertilizing products, as well as the fertilizing products blends where a 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 organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizers 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. 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.
