“…Yao et al (2019) also observed that aromatic CC groups were higher in the SOM from three cultivated areas than in native grasslands. Aliphatic CH was also observed to be more concentrated under the tree line than tillage operations (Table 2), which is consistent with that of Thai et al (2021), who found that forest soil spectra have more intense aliphatic bands than the spectra of cropland soils. Moreover, Schnitzer et al (2006) reported an increase in aromatics and a decrease in SOM aliphatic content with increasing cultivation intensity.…”

“…Several parameters affect SOM composition, including the decomposition rate, types of plant residues, soil texture, microbiological composition, chemical and mineralogical composition, and climatic conditions such as temperature and moisture content (Lal, 2018; Thai et al, 2021). In addition, artificial effects, such as physical disturbance, and land use may also determine SOM composition (Abera & Belachew, 2011; Adiyah et al, 2022; Alam et al, 2014; Cao et al, 2011; Helfrich et al, 2006; Qin et al, 2016; Yu et al, 2015; Zhang et al, 2017).…”

“…Another source of interest is the uncertainty regarding the influential role of sources or sinks that soils can play in the global carbon cycle (Vilakazi et al, 2022), with implications for the greenhouse effect and climate change (Disnar et al, 2003; Lefèvre et al, 2017). However, most studies have focused on forest and grassland (Pisani et al, 2016; Thai et al, 2021; Wang et al, 2016) ecosystems, and only a few have investigated SOM composition in agricultural soils, particularly concerning tillage practices (Gao et al, 2021; Helfrich et al, 2006; Moussadek et al, 2014).…”

The effects of land use change on soil organic carbon (SOC) content have been investigated extensively. However, little research has been conducted on how soil organic matter (SOM) chemistry changes under different land use management practices, particularly with different soil cultivation methods. Thus, in this study, we compared the effects of various land use management practices, including six medium‐term tillage practices, namely no‐tillage (zero‐tillage), disking, shallow cultivation, deep cultivation, ploughing, and loosening, and a natural ecosystem, namely tree line, on SOM composition. The present study examined Chernozem soils during spring and autumn under varying land uses in randomised complete block designs, with four replicates at depth increments of 0–10 cm. The SOM composition was characterised using diffuse reflectance infrared Fourier transformat spectroscopy (DRIFTS) and ultraviolet–visible spectroscopy (UV‐VIS). More intensive tillage operations resulted in larger SOM composition changes. Overall, conservation tillage, namely no‐tillage, disking, shallow cultivation, and deep cultivation, SOM was more like the tree line soil than the soil under conventional tillage. Both DRIFTS and UV‐VIS revealed that tree line soil had the lowest aromaticity (15%) and, therefore, a lower decomposition rate and higher SOM recalcitrance compared with the cropland soil (27%). After observing the relationship between tillage operation and aromaticity, aromaticity increased with increasing tillage intensity. This study demonstrates that land use can alter the structure and stability of SOM compounds. We observed that afforestation is similar to conservation tillage, and results are obtained quickly (<40 years). Hence, regeneration agriculture and conservation tillage may be the superior solutions for increasing SOM, sustainable agriculture, and food security in current soil and climate conditions. In addition, DRIFTS measurements of bulk soil provided more detailed information on the quality and stability of SOM than UV‐VIS measurements.

“…Due to the darkness of forest soil samples, the spectra were recorded by 120 scans in wavenumbers ranging from 4000 to 400 cm −1 at a resolution of 4 cm −1 . The measured reflectance was converted to Kubelka-Munk units (KM), and the gold mirror was used as the background of the spectra (Thai et al 2021). The potential wettability index (PWI), aromaticity index (iAR), and decomposition index (iDEC) were determined using DRIFT spectra.…”

The study aimed to investigate the temporal changes of pH, sorption complex, and structure of soil organic matter through the forest soil profile under beech and spruce forests located in Jizera mountains (Czech Republic) and affected by natural and anthropogenic acidification. Soil samples were collected in four different years (2008, 2013, 2015, and 2020) in each horizon: fermented horizons (F), humified horizons (H), organo-mineral horizons (A), and subsurface mineral horizons (B) (cambic or spodic). The cation exchange capacity (CEC), base saturation (BS), exchangeable element contents, pH, and soil organic carbon content (SOC) were determined. The infrared soil spectra were used to calculate indices of potential wettability, aromaticity, and decomposition. Our results showed that most nutrients and aliphatic compounds were retained in the uppermost soil layers. The aromaticity of organic matter increased with depth, while polysaccharides, regarding the decomposition compound, disappeared through the soil horizons. In a long-term observation, SOC content had constantly increased under beech, while spruce remained stable in the organic horizons. Exchangeable element contents increased in each horizon, except for Al and Fe; their content quickly decreased in F horizons and slowly decreased in H horizon under both forest tree species, while the deeper horizons remained constant, but increased in A horizon under spruce. Continuously increasing base cations concentrations in sorption complex of both forest tree species during the study period revealed the effect of forest stand types on acid deposition reduction and mitigation. The temporal changes in CEC, BS, SOC, and soil wettability are more intensive in beech than in spruce forest floor.

“…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.
