[EN]: Non destructive spectroscopic methods such as 13C- and 15N-NMR provide new insights into the structure of humic substances. Solid state NMR is capable of studying complete native soils by the CPMAS-technique. By means of nitrogen 15-enriched composts it is suggested that nitrogen in soil organic matter is mainly located in amide and peptide structures. Most probable assignments are given. The investigation of humification processes in forest soils is possible via an approach which uses several fractionation techniques in combination with degradative and non-degradative analytical techniques. Besides structure analysis, the 13C-NMR-spectroscopy provides important information about the functions of humic substances. By using 13C-e...
