“…In all the test samples of chernozem and sod-podzolic soils, matrix minerals are composed mainly of quartz species, hydrosilicate minerals-illites and smectites-and clay minerals with the due percentage of amorphous silicon dioxide or hydrosilicate species [82,83,85,[90][91][92][93][94][95]. Due to the complexity of samples and many (although sometimes non-detailed) assignments in the literature, we summed up all the possible entries in an assignment table (Table 1), giving both counterparts of target bands, inorganic matrix components, and SOM constituents.…”

“…The soil is agrosod-podzolic medium loamy (sod-podzolic, Umbric Albeluvisols Abruptic (WRB 2006), Eutric Podzoluvisols (FAO)) formed on a mantle loam, underlain at a depth of 2-3 m with non-carbonate moraine. The content of silt fraction of ≤1 µm is 15-16% [82]. Minerals with a rigid structure dominate the mineralogical composition of the clay fraction (hydromica, chlorite-vermiculites, kaolinite, chlorites in the upper part).…”

Organic Matter and Mineral Composition of Silicate Soils: FTIR Comparison Study by Photoacoustic, Diffuse Reflectance, and Attenuated Total Reflection Modalities

2021

This study aims to compare photoacoustic (FTIR–PAS), diffuse reflectance (DRIFT), and attenuated total reflection (ATR) FTIR modalities in the wide wavenumber range from NIR (7500 cm−1) to FIR (150 cm−1) for the same silicate soil samples under the same conditions. The possibilities of non-destructive rapid qualitative analysis of soils by these modalities without comprehensive data treatment were compared. The assignment of more than 100 bands for the chernozem and sod-podzolic as common types of silicate types of soil was made. The following groups of bands of organic matter and inorganic matrix were reliably found in spectra of all or at least two modalities: 3690–3680 cm−1 (hydrogen-bonded SiO–H…H2O stretch, not ATR), 2930–2910 cm−1 and 2860–2850 cm−1 (methylene stretch), 1390–1380 cm−1, (symmetric stretch carboxylate, DRIFT and FTIR–PAS); 2000–1990 cm−1, 1885 cm−1, and 1790–1783 cm−1 (SiO2 overtones, DRIFT and FTIR–PAS), 1163–1153 cm−1, SiO2 lattice (not FTIR–PAS), 1037 cm−1 (Si–O or Al–O stretch), 796 cm−1 (lattice symmetrical Si–O–Si stretch); 697 cm−1, SiO2; and 256 cm−1 (not FTIR–PAS). Amide I, II, and III bands appear in DRIFT and FTIR–PAS spectra while not in ATR. Except for methylene and carboxylate groups, CH vibrations (3100–2900 cm−1) are not seen in ATR. Bands at 1640–1630 cm−1, 1620–1610 cm−1, 1600–1598 cm−1 (primary water bands and probably carboxylate) appear in the spectra of all three modalities but are unresolved and require data treatment. It is preferable to use all three modalities to characterize both soil organic matter and mineral composition. DRIFT provides the maximum number of bands in all three modalities and should be selected as a primary technique in the NIR and 4000–2000 cm−1 regions for hydrogen-bonding bands, CHX groups, and the silicate matrix. ATR–FTIR complements DRIFT and provides a good sensitivity for soil water and the matrix in 2000–400 cm−1. FTIR–PAS in 4000–1500 cm−1 reveals more bands than DRIFT and shows the highest sensitivity for absorption bands that do not appear in DRIFT or ATR-IR spectra. Thus, FTIR–PAS is expedient for supporting either DRIFT or ATR–FTIR. This modality comparison can be a basis for methodological support of IR spectroscopy of soils and similar organomineral complexes.

“…Since 2011, the field has not been plowed; a fallow has formed (Sonchus arvensis, Festuca pratensis, Phleum pratense, and Dactylis glomerata). Samples were taken in 2016; the coordinates of the sampling site are 56° 07′ 56″ N 37° 48′ 09″ E. Sludge content in the upper (arable) horizon of unflushed full-profile sod-podzolics varies from 10 to 16% . Minerals dominate the mineralogical composition of the clay fraction with a rigid structure (hydromica, kaolinites, chlorites in the upper part).…”

FTIR Photoacoustic and ATR Spectroscopies of Soils with Aggregate Size Fractionation by Dry Sieving

et al. 2022

Granulometric fractionation as a source of additional information on organic-matter and inorganic matrix components of soils using FTIR–photoacoustic spectroscopy (FTIR–PAS) supported by attenuated–total reflection FTIR spectroscopy (ATR–FTIR) for a wide range of aggregate fractions (10–5000 μm) was used to compare the sensitivity, reproducibility, information contents, and representativity of fractionated samples. For chernozem and sod-podzolic soils and different agricultural-use chernozem samples, differences in the composition were found, manifested in normalized spectra of microaggregate fractions, with the range of 10–100 μm bearing the complete information. Most changes are observed in the soil organic matter range (1900–1340 cm–1), although these changes are slight, and in the soil-matrix region (550–300 cm–1). The latter region increases the intensity of bands corresponding to amorphous silica and clay minerals in fine fractions, while the intensity of bands attributed to quartz lattice vibrations decreases. FTIR–PAS spectra do not differ considerably at high interferometer modulation frequencies as the signal-penetration depth is comparable with particle sizes. The soil fractions below 20 μm result in the maximum sensitivity, reproducibility, and signal-to-noise ratio, showing no changes from coarser fractions by the information content and, thus, providing representative samples for analysis. The fractionation shows more differences in the sod-podzolic and chernozem soil fractions than the whole soil spectra. FTIR–PAS provides better sensitivity and reproducibility in the 4000–2000 cm–1 region and ATR–FTIR in the 2000–100 cm–1 region.
