This standard 25/30478144 DC Draft BS EN 13039 Soil improvers and growing media - Determination of organic matter content and ash is classified in these ICS categories:

• 65.080 Fertilizers

This document specifies a routine method for determining the organic matter and the ash content of soil improvers and growing media. NOTE The loss on ignition (LOI) is often used as an estimate for the content of organic matter in the sample. Inorganic substances or decomposition products (e.g. H2O, CO2, SO2, O2) are released or absorbed and some inorganic substances are volatile under the reaction conditions. Thus, a conversion to the organic carbon content is not possible.
