Abstract

Decomposition and humification were studied within two forest humus profiles (mor and moder) by means of density fractionation combined with subsequent micromorphological, wet-chemical, and CPMAS 13C NMR spectroscopic characterization of the fractions. The data show that the decomposition of plant polysaccharides leads to a relative accumulation of refractory structures within the plant residues of the mineral soils: non-phenolic aromatic structures for the mor and long-chain unsubstituted aliphatic structures for the moder. In both mineral soil horizons the organo-mineral complexes have high carbohydrate contents.
