Quantitative Characterization of Soil Organic Matter and Its Fractionation Products by Solid State High Resolution C-13 (CPMAS) Spectroscopy

Abstract

In a systematic study the organic carbon content of typical Germ an soils was studied by solid state C-13 CPM AS spectroscopy. In order to check the quantitative validity of the standard sodium hydroxide extraction procedure, which fractionates soil organic matter into hum in, 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.
