“…Matejkova and Simon (2012) and Winarna (2015) stated that hydrophobicity is the ratio between hydrophobic components and hydrophilic components in peat soil. Szajdak and Szatylowicz (2010) stated that the groundwater fluctuations affected the hydrophobicity of the peat as it could affect chemical composition of humic substances in peat soil.…”

“…The functional groups C-H, C=C, OH and C=O attributed the nature of irreversible drying (hydrophobicity) on peat soil (Urbanek et al 2007;Utami et al 2009;Dlapa et al 2012;Matejkova and Simon 2012). Results of hydrophobicity interpretation showed that GWL-1 treatment with a final moisture content of 37% for BD-1 and 49.9% for BD-2 had entered the hydrophobicity.…”

Capillary water in peatlands has a very important role in supplying water to the root zone of plants. The current water content in the root zone depends mainly on groundwater levels in some areas with shallow water levels. The study aimed to measure the capillary water dynamics in peat soils at various soil densities and groundwater levels which were observed from the changes in peat color, moisture distribution, water content and hydrophobicity of peat soil. The study was conducted in the greenhouse of Indonesian Swampland Agricultural Research Institute, Banjarbaru, South Kalimantan. The experiment was arranged in a randomized block design with two factors and three replications. The first factor was the bulk density (BD) of peat, namely BD-1 (on actual condition, 0.1 g cm -3 ) and BD-2 (compressed into 0.2 g cm -3 ). The second factor was simulated groundwater levels (GWL) consisting of GWL-1 (-100 cm), GWL-2 (-70 cm) and GWL-3 (-40 cm) from soil surfaces. The results showed that the rise of capillary water in peat soil reached a maximum height of 50 cm which was characterized by the increase in water content at the top layer in the range of 105-127% for BD-1 and 141-181% for BD-2. The highest value of water content (308%) was achieved in the treatment of GWL-3 with BD-2 and the lowest (37%) was in the treatment of GWL-1 with BD-1. The rate of capillary water rose progressively corresponded to the increase in BD value because the number of micropores of BD-2 was greater.

“…Artz, et al (2006) used the 1600/1030 bands ratio (carboxylate/polysaccharide) as an index of decomposition in peat, suggesting that the band near 1630 cm -1 represents a relatively recalcitrant form of organic C, probably a combination of lignin and humic substances. Other authors (Ellerbrock, et al, 2005(Ellerbrock, et al, , 2009Matějková and Šimon, 2012) proposed measuring the ratio of absorption bands related to relatively hydrophobic (3000-2800 cm -1 ) and hydrophilic (1740-1698 and 1640-1600 cm -1 ) SOM functional groups. The hydrophobic/hydrophilic functional groups ratio was used to predict the wettability or hydrophobicity of soils (Ellerbrock, et al, 2005).…”

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.

“…It is of great importance to know the intensity of these bands, because with these can be estimated the hydrophilic organic components. It was found in [51] that these band lengths correlate significantly with OC groups and also with soil N.…”

Abstract:In this study, the spectral responses obtained from a Typic Red Hapludox (oxisol) were analyzed under different uses and occupations: Ficus elastica cultivation, Citrus + Arachis association cultivation, transitional crops, forest, Mangifera indica, Anacardium occidentale, Elaeis guineensis (18 years), Brachiaria decumbens, Brachiaria brizantha, and Musa × paradisiaca + Zea mays at the La Libertad Research Center in the department of Meta in Colombia (4 • 04 North latitude, 73 • 30 West longitude, 330 MAMSL). Sampling was performed with four random replicates of the horizon A and B to determine the contents of organic carbon (CO), pH, exchangeable acidity (Ac. I), cation exchange capacity (Cc), P, Ca, Mg, K, Na, sand, lime, and clay and spectral responses were obtained in the visible band (VIS), near infrared (NIR), and infrared (MIR) for each sample under laboratory conditions. A comparison was made between the obtained spectra, determining the main changes in soil properties due to their use and coverage. Variation of soil characteristics such as color, organic carbon content, presence of ferrous compounds, sand, silt, and clay content and mineralogy allow the identification of the main spectral changes of soils, demonstrating the importance of the use of reflectance spectroscopy as a tool of comparison and estimation between physical-chemical properties of the soils.
