“…Considering that the long-term fertilization did not affect the amounts of SOC detected in the clay fraction, it is not as straightforward for phenol to explain the effect of clay on its sorption. Recently, however, advanced spectroscopic methods revealed qualitative differences in the composition of soil organic matter at the clay fractions from these soil variants (Demyan et al, 2012). It was suggested that soil organic matter of clay consists of at least two different fractions: one responsive to environmental change, like induced by long-term fertilization, and the other not (Leifeld and Kö gel-Knabner, 2005).…”

Many organic pollutants are readily degradable by microorganisms in soil, but the importance of soil organic matter for their transformation by specific microbial taxa is unknown. In this study, sorption and microbial degradation of phenol and 2,4-dichlorophenol (DCP) were characterized in three soil variants, generated by different long-term fertilization regimes. Compared with a non-fertilized control (NIL), a mineral-fertilized NPK variant showed 19% and a farmyard manure treated FYM variant 46% more soil organic carbon (SOC). Phenol sorption declined with overall increasing SOC because of altered affinities to the clay fraction (soil particles o2 mm in diameter). In contrast, DCP sorption correlated positively with particulate soil organic matter (present in the soil particle fractions of 63-2000 lm). Stable isotope probing identified Rhodococcus, Arthrobacter (both Actinobacteria) and Cryptococcus (Basidiomycota) as the main degraders of phenol. Rhodococcus and Cryptococcus were not affected by SOC, but the participation of Arthrobacter declined in NPK and even more in FYM. 14 C-DCP was hardly metabolized in the NIL variant, more efficiently in FYM and most in NPK. In NPK, Burkholderia was the main degrader and in FYM Variovorax. This study demonstrates a strong effect of SOC on the partitioning of organic pollutants to soil particle size fractions and indicates the profound consequences that this process could have for the diversity of bacteria involved in their degradation.

“…KBr-pellet), DRIFT or ATR, depends on parameters such as the sample size, the information needed (bulk versus surface analysis) or the time required for the sample preparation. Currently, the improved design of DRIFT accessories has made this technique widely used for studying soil compounds (Aguiar, et al, 2013;Calderon, et al, 2011aCalderon, et al, , 2011bDemyan, et al, 2012;Ellerbrock, et al, 2009;Francioso, et al, 2009;Leue, et al, 2010;Ludwig, et al, 2008;Minasny, et al, 2008); ATR is also now being widely used (Artz, et al, 2008;Gezic, et al, 2012;Neves-Fernandes, et al, 2010;Vergnoux, et al, 2011).…”

“…This technique was introduced by Nguyen, et al (1991) for studying soil chemical composition and was subsequently used to investigate SOM and the chemical composition of humic substances, as well as the effect of amendment practice on soil (Aguiar, et al, 2013;Calderon, et al, 2011aCalderon, et al, , 2011bDemyan, et al, 2012;Ellerbrock, et al, 2009;Ferrari, et al, 2011;Janik, et al, 2007a;Kaiser, et al, 2007;Leue, et al, 2010;Ludwig, et al, 2008;Minasny, et al, 2008;Reeves III and Smith, 2009). It has also been applied to study many other agricultural related aspects such as the composition of different coal ranks (Chen, et al, 2012;Li, et al, 2010) and their soluble SOM fraction (Gezic, et al, 2012;Ghosh, et al, 2009), the chemistry of waste and compost materials (Huber-Humer, et al, 2011;Salati, et al, 2013;Smidt and Meissl, 2007), the decomposition processes of forest litter (Duboc, et al, 2012;Nault, et al, 2009;Osono, et al, 2011;Tatzber, et al, 2010), the chemical structure of pyrogenic organic matter (OM) Nocentini, et al, 2010) and the behaviour of chemical compounds adsorbed on clays (Aochi and Farmer, 2011;Dorado, et al, 2010).…”

“…In this way, MIR can be used as a quantitative technique, assuming that the dipole moment-related "response factor" is taken into account (Griffiths and De Haseth, 2007). MIR spectroscopy has frequently been applied to investigate soil properties and soil organic matter (SOM) characteristics (Aguiar, et al, 2013;Bellon-Maurel and McBratney, 2011;Calderon, et al, 2011aCalderon, et al, , 2011bDemyan, et al, 2012;Du and Zhou, 2009;Francioso, et al, 2009;Haberhauer and Gerzabek, 1999;Kaiser, et al, 2011). Currently, the combination of multivariate statistical methods used for the Fourier Transform IR (FTIR) spectra analysis has provided a powerful method for the discrimination and identification and/or quantification of single components in soils (Aguiar, et al, 2013;Bellon-Maurel and McBratney, 2011;Bornemann, et al, 2010;Calderon, et al, 2011aCalderon, et al, , 2011bD'Acqui, et al, 2010;Fernandez-Getino, et al, 2013;Janik, et al, 2007aJanik, et al, , 2007bLudwig, et al, 2008;Minasny, et al, 2008;Pirie, et al, 2005;Reeves III, 2010;Stumpe, et al, 2011;Tatzber, et al, 2010;Viscarra Rossel, et al, 2006;Yang, et al, 2012).…”

The present review highlights the recent applications of mid-infrared spectroscopy and in particular of diffuse reflectance spectroscopy (DRIFT) and attenuated total reflectance (ATR) and processing methods (e.g., deconvolution, derivative and chemometrics) to rapidly provide valuable information on soil composition and organic geochemistry. Research has demonstrated that both DRIFT and ATR techniques can be considered useful tools for the analysis of a large number of soil samples, giving not only typical spectral patterns but permitting an accurate prediction of quantitative parameters such as, e.g., total carbon, total nitrogen, C/N ratio, lignin, dissolved OC, carbonyl-C, aromatic-C, O-alkyl-C, and alkyl-C contents. Based on literature results, infrared spectroscopy can be recognized as one of the most promising analytical techniques for investigating soil science.

“…The SOM composition can be determined in terms of organic matter functional groups using Fourier transform infrared (FTIR) spectroscopy (e.g., Demyan et al, 2012) or nuclear magnetic resonance (NMR) spectroscopy (e.g., Celi et al, 1997;Schaumann et al, 2013). The potential wettability of SOM was characterized by the ratio between the FTIR signal intensities of hydrophobic aliphatic C-H groups and hydrophilic C = O groups (Ellerbrock et al, 2005).…”

Abstract:The organo-mineral coatings of soil aggregates, cracks, and biopores control sorption and macropore-matrix exchange during preferential flow, in particular in the clay-illuvial Bt-horizon of Luvisols. The soil organic matter (SOM) composition has been hypothesized to explain temporal changes in the hydraulic properties of aggregate surfaces. The objective of this research was to find relations between the temporal change in wettability, in terms of droplet infiltration dynamics, and the SOM composition of coated and uncoated aggregate surfaces. We used 20 to 40 mm sized soil aggregates from the Bt2 horizon of a Haplic Luvisol from loess that were (i) coated, (ii) not coated (both intact), and (iii) aggregates from which coatings were removed (cut). The SOM composition of the aggregate surfaces was characterized by infrared spectroscopy in the diffuse reflection mode (DRIFT). A potential wettability index (PWI) was calculated from the ratio of hydrophobic and hydrophilic functional groups in SOM. The water drop penetration times (WDPT) and contact angles (CA) during droplet infiltration experiments were determined on dry and moist aggregate samples of the three types. The decrease in the CA with time was described using the power function (CA(t) = at -b ). For dry aggregates, the WDPT values were larger for coated as compared to uncoated regions on the aggregate surfaces, and increased with increasing PWI value (R 2 = 0.75). The a parameter was significantly related to the WDPT (R 2 = 0.84) and to the PWI (R 2 = 0.64). The relations between the b parameter and the WDPT (R 2 = 0.61) and the PWI (R 2 = 0.53) were also significant. The WDPT values of wet soil aggregates were higher than those of dry aggregates due to high water contents, which limited the droplet infiltration potential. At the wet aggregate surfaces, the WDPT values increased with the PWI of the SOM (R 2 = 0.64). In contrast to dry samples, no significant relationships were found between parameters a or b of CA(t) and WDPT or PWI for wet aggregate surfaces. The results suggest that the effect of the SOM composition of coatings on surface wettability decreases with increasing soil moisture. In addition to the dominant impact of SOM, the wettability of aggregate surfaces could be affected by different mineralogical compositions of clay in coatings and interiors of aggregates. Particularly, wettability of coatings could be decreased by illite which was the dominant clay type in coatings. However, the influence of different clay mineral fractions on surface wettability was not due to small number of measurements (2 and 1 samples from coatings and interiors, respectively) quantified.
