Popis: In this study, soil samples taken from a wetland from the surface to a depth of 160 cm were analyzed for water extracted organic matter (WEOM) fractions by UV/Vis and for lignin and polysaccharide components directly by Fourier transform infrared spectroscopy (FTIR). Our results indicate that lignin-derived phenolic compounds in the WEOM fractions decreased with increasing soil depth at three different wavelengths. This decrease was consistent with our FTIR results and was accompanied by a decrease of polysaccharides. Our study demonstrates the application of UV/Vis and FTIR to directly differentiate lignin and polysaccharide concentration gradients in a soil profile.
