In Modal Chernozem highest HA amount was found. Fulvic acids highest amount was found in both Cambisols. HA/FA ratio indicated decreasing HS quality in order: Modal Chernozem < Modal Rendzina < Modal Pararendzina < Modal Cambisol < Litic Cambisol. Linear correlation between Q 4/6 and HA sum was found. UV-VIS spectra showed the highest absorbance in Modal Chernozem. Optical indexes Q4/6 indicated high HS quality in Modal Chernozem and low in Litic Cambisol. Fluorescence of studied samples was compared with literature data and/or with standard. Samples contained substitued naphtalene and coumarine derivates. Samples had similar fluorescence behaviour as Elliot soil humic acid standard (IHSS) and all samples indicated two main excitation peaks at 450, 468 nm. Low relative fluorescence index (F) was found in Modal Cambisol (0.73). Highest index F was in Modal Pararendzina (1.16). From SFS spectra we can also suggested highest intensity of fluorescence in Modal Chernozem. These results were confirmed by HS fractionation but maximum F index in Modal Chernozem was not determined.
