ABSTRACT:
Method for the determination of the content of solid carbon compounds in soil samples, particularly in humus soils, by converting the solid carbon compounds with a reactant into carbon dioxide and conveying the carbon dioxide gas into an analyzer. To reach the reaction temperature, metal particles are added to a specified amount of the dry, milled soil sample and the dry matter is heated inductively in the presence of the reactant to the reaction temperature.
