“…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].…”

Soil organic matter (SOM) quantity and quality are important factors that significantly influence soil fertility. SOM quality indicators change throughout time. In this study, long—term field experiments (22–50 years in duration) on a Cambisol at four sites in the Czech Republic were selected. Seven crops were successively rotated in the sequence: clover, winter wheat, early potato, winter wheat, spring barley, potato, and spring barley with interseeded clover. Five treatments were investigated, including an unfertilized treatment, farmyard manure, and various combinations of farmyard manure and mineral fertilization. A total of 40 t ha−1 of farmyard manure was applied to the early potato and potato crops. Combining organic and mineral fertilizers increased soil organic matter quality and quantity over unfertilized or organic only treatment. The highest intensity of mineral fertilizers in our trials elevated the mean of carbon sequestration efficiency to 45.6% in comparison to pure manure treatment which reached only 22.9% efficiency. A strong correlation was established between the total glomalin content and soil organic matter carbon, fulvic acid, humic acid, carbon hot water extraction, potential wettability index (PWI), and aromaticity index. The PWI was also strongly correlated with these indicators. The E4/E6 ratio indicator was shown to be a much less sensitive method for reflecting the change in soil organic matter quality.

“…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.…”

“…In mixtures of substances such as soil, identification of individual molecules is difficult because the spectral bands of the organic and mineral components of the soil may overlap. Although mid-IR spectroscopy has its limits given the complexity of the soil, it detects the presence of important functional groups of SOM, and thus it can provide information about relative differences in SOM composition in different soil types and soil horizons (Pavlů et al 2023) or for example in different land use (Thai et al 2021).…”

This study focuses on the effect of agricultural soil management on soil organic matter (SOM) composition. The addition of manure and crop residues was tested under different pedoclimatic conditions. The quality of SOM was assessed using diffuse reflectance infrared spectroscopy. The following parameters were calculated from the spectra: sum of aliphatic bands (ΣAL), aromatic bands at wave numbers 1 620 and 1 520 cm -1 (AR 1620 and AR 1520 ), potential wettability (PWI), organic matter quality (OMQ), and decomposability (DI) indexes. The addition of manure or crop residues may not cause fundamental changes in the qualitative composition of SOM. Rather, pedoclimatic conditions determine which components are fixed in the soil on a long-term scale. A dominant effect of soil type was found in the distribution of all spectral parameters studied using main effect ANOVA. The main differences between the soil types concern the aromatic, oxygen and nitrogen groups contained in the SOM. Chernozems are soils with higher OMQ and DI, whereas Cambisols are soils with low OMQ and DI and the highest PWI. The stabilisation of SOM in soils can thus be based on the biochemical persistence of organic molecules, their specific affinity for minerals and the formation of aggregates that protect enclosed SOM.
