“…Cambisols typically have a lower organic matter quality index and decomposition index in comparison to Chernozems and Luvisols [4]. However, the stability of soil organic matter is influenced not only by the composition of organic matter, its aromaticity, and nitrogen content but also by other factors.…”

“…Infrared spectroscopy in the mid-infrared spectrum can identify SOM composition without physical or chemical extraction or separation from soil. Although it has its limits due to the complex nature of the soil, this method can detect some functional groups within soil organic matter and offer insights into relative differences in SOM composition across distinct soil horizons or soil types [4].…”

“…The exception are the bands of carbonates (around 2 515 and 1 450 cm -1 ) which are slightly visible in the several individual spectra. The spectra were normalized with the reflectance (converted to Kubelka-Munk units) of the bands at 810 cm -1 for mutual comparability of individual peaks (Pavlů et al 2023). In the following text se- in the case of two aliphatic bands sum (in the range 2 950-2 820 cm -1 ) and AR 1620 or AR 1520 in the case of bands including vibration of aromatics around 1 620 and 1 520 cm -1 , respectively.…”

“…The ratio of the band around 1 640-1 600 cm -1 and the aliphatic band (around 2 930 cm -1 ) was used as an indicator describing OMQ which is applicable for noncarbonates and carbonates soil (Pavlů et al 2023) because selected bands do not overlap even in carbonate soils and identify important components of SOM. Based on this index, the relative proportion of aliphatic, aromatic, or C=O-containing groups of SOM was evaluated.…”
