“…Thus, FTIR provides valuable information on the material transformation mechanism, which was also suggested by Cao and Tan (2004). The absorption peak position and relative intensity of the FTIR results reflected changes in the cellulose, hemicellulose, and lignin components in different functional groups (Francioso et al 2011). Rodrigues et al (1998) used FTIR spectroscopy to quantitatively determine the amount of lignin in Eucalyptus globulus, and they concluded that the best calibration fit was obtained using peak height ratios at 1505 and 1158 cm -1 for lignin and carbohydrates, respectively.…”

Changes in the physical structure and nutrients contents of apple branches were explored after decomposition, and the soil quality of an orchard was evaluated after returning apple branches in situ. Scanning electron microscopy, X-ray diffractometry, and Fourier transform infrared spectroscopy were used to analyse the structural changes of the experimental material. The results showed that the structure of this material is obviously destroyed in the transverse sections and longitudinal sections. Collapsed cell walls had a negative effect on complete branches, which presented sharp decreases in cellulose contents and the partial removal of lignin and carbohydrate contents by the third year. In a final analysis of the nutrients in the branches, there was an obvious decline in macroelements (e.g., phosphorus and potassium), whereas manganese, which is a limiting factor, increased by 4-fold compared with the control. The results indicated that the addition of mulch from branches can be used to maintain a high soil quality in the third year of decomposition.

“…In addition, some charcoals are characterized by the presence of a weak band at ca. 2220 cm -1 , which was assigned to CN stretching vibration of iso-cyanate, nitrile and cyanamide groups (Francioso, et al, 2009;Francioso, et al, 2011;Nocentini, et al, 2010).…”

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.

“…Sin embargo, estos cambios en la estructura química no pueden ser observados mediante técnicas de análisis térmico, por ello la combinación de éstas con técnicas espectroscópicas (RMN ó FT-IR por ejemplo) ha sido considerada especialmente conveniente (Lammers et al 2009;Nocentini et al, 2010;Francioso et al, 2011).…”
