Taikymo sritis

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.
