“…In the clayey soil, the high content of clay particles probably affect soil characteristics directly and indirectly (Sarkar et al, 2018), causing soil compaction (Churchman, 2018) and probably arising many potential problems, e.g. low infiltration rates (Alaoui et al, 2018) beside of poor drainage and aeration conditions (Obia et al, 2018).…”

“…is may be due partly to the unjustified assumption that a given soil mineral will have the same properties as those of its better-crystallized counterpart that formed in a more "geologic" context (e.g., sedimentary kaolinite will have the same properties as pedogenic kaolinite) [4]. Revisiting soil mineralogy has been gradually important, for instance, in terms of the manner by which soil minerals are de ned and investigated [8].…”

Clay minerals are the most reactive and important inorganic components in soils, but soil mineralogy classifies as a minor topic in soil sciences. Revisiting soil mineralogy has been gradually required. Clay minerals in soils are more complex and less well crystallized than those in sedimentary rocks, and thus, they display more complicated X-ray diffraction (XRD) patterns. Traditional characterization methods such as XRD are usually expensive and time-consuming, and they are therefore inappropriate for large datasets, whereas visible and near-infrared reflectance spectroscopy (VNIR) is a quick, cost-efficient, and nondestructive technique for analyzing soil mineralogic properties of large datasets. The main objectives of this review are to bring readers up to date with information and understanding of VNIR as it relates to soil mineralogy and attracts more attention from a wide variety of readers to revisit soil mineralogy. We begin our review with a description of fundamentals of VNIR. We then review common methods to process soil VNIR spectra and summary spectral features of soil minerals with particular attention to those <2 μm fractions. We further critically review applications of chemometric methods and related model building in spectroscopic soil mineral studies. We then compare spectral measurement with multivariate calibration methods, and we suggest that they both produce excellent results depending on the situation. Finally, we suggest a few avenues of future research, including the development of theoretical calibrations of VNIR more suitable for various soil samples worldwide, better elucidation of clay mineral-soil organic carbon (SOC) interactions, and building the concept of integrated soil mapping through combined information (e.g., mineral composition, soil organic matter-SOM, SOC, pH, and moisture).

“…For example, though the soils under tropical forests store the highest amount of OC, desert soil stores the lowest amount of OC [21,22]. Soil silt and clay content maintains organic carbon by aggregation [15,23]. Hassink [19] revealed an increase in the SOC stored in the <20 μm size fraction with an increase of clay + silt content.…”

Soil organic carbon (SOC) and microbial biomass carbon (MBC) are important components of soil organic matter (SOM). SOC and MBC have generally recognized key parameters of soil quality and health, and also they have been linked to forest ecosystem productivity, using as a sensitive indicator for ecosystem monitoring programs. Both of them play a crucial role in the carbon cycle and influence many environmental, biological, and chemical factors. Soil organic matter decomposition by soil microorganisms contributes to the nutrient availability and release in an ecosystem. This interaction between SOM and MBC is managed in soil aggregation, soil porosity, moisture content, and aeration. Forest soils can store more carbon than other land uses because they contain a wide variety of soil microorganisms. Enhancing these two important components of soil can contribute to climate change mitigation and adaptation strategies. In this chapter, an overview of the understanding of the most important soil quality and health factors managed soil C in forest soils and provided how seasonal changes affect soil organic carbon and microbial biomass carbon.
