variable_of entity Total mineral content based on reference values obtained by ashing at 550°C. In the case of this method Mineral Matter (MM) concentration is predicted using a NIRS calibration and calculated in reference to the dry matter (DM) content. The NIRS calibration information has to be provided. Method abbreviation: MMNIRS Mineral Matter determination in the dry matter using NIRS calibration - Prediction scale_of method_of attribute acronym
