dcterms:description
Current concern for soil quality has stimulated research on soil organic matter (OM). Humic substances (HS) of different origin were compared applying UV/VIS spectroscopy, Fourier transform infrared spectroscopy (FTIR), fluorescence spectroscopy, and 13C nuclear magnetic resonance (13C NMR). Sodium humates samples were isolated from soil (Gleyic Luvisol), compost, and South Moravian lignite from the mine Mír in Mikulčice. Sodium humates (SH) were extracted by a conventional procedure recommended by the International Humic Substances Society (IHSS). Results showed that the presence of O containing functional groups (carbonyl in aldehydes and ketones, carboxyl in carboxylic acids, ester and ether groups) are in the order of compost > soil > lignohumate > lignite. Further, results of FTIR, fluorescence spectroscopy, and 13C NMR suggested that samples of sodium humates isolated from soil, compost, and lignite were a more polycondensed, oxidized, unsaturated, humified, and aromatic structure.
