Soil improvers and growing media - Methods for the determination of PAH₁₆, macroscopic impurities above 2 mm, the temperature-time profiles, oxygen uptake rate, self-heating factor and residual biogas potential in compost and digestate when used in fertilizing products; German and English version prEN 17730:2026
Abstract
This document refers to methods to be used for the determination of specific parameters in compost, fresh crop digestate and digestate other than fresh crop digestate when used as components of fertilizing products, but does not contain the methods themselves. The specific parameters in this document include: — the determination of the PAH16 content; — macroscopic impurities; — the determination of temperature-time profiles during composting and digestion; — oxygen uptake rate; — self-heating factor; — the determination of the residual biogas potential in digestate. This document is applicable to the 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 are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply. NOTE 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).
