Abstract
In a systematic study the organic carbon content of typical German soils was studied by solid state C-13 CPMAS spectroscopy. In order to check the quantitative validity of the standard sodium hydroxide extraction procedure, which fractionates soil organic matter into humin, humic acid, and fulvic acid also the high resolution solid state spectra of these fractions were determined. The chemical information obtained from these spectra is discussed. © 1991, Verlag der Zeitschrift für Naturforschung. All rights reserved.
