Visible and Near-Infrared Reflectance Spectroscopy for Investigating Soil Mineralogy: A Review

open access: yesJournal of Spectroscopy, 2018
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.

Monitoring Soil Surface Mineralogy at Different Moisture Conditions Using Visible Near-Infrared Spectroscopy Data

open access: yesRemote Sensing, 2019
The soil minerals determine essential soil properties such as the cation exchange capacity, texture, structure, and their capacity to form bonds with organic matter.

The role of conservation soil management on soil and water protection at different spatial scales [PDF]

open access: yes, 2006
Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

Response of Soil Mineral Weathering to Elevated Carbon Dioxide [PDF]

open access: yes, 2002
Understanding the rates of weathering of soil minerals and the factors that may either enhance or inhibit these rates is a crucial part of understanding many processes from the watershed to the global scale.

WETLAND'S REVEGETATION IMPACT ON SOME SOIL PROPERTIS AT MANZALA REGION, EGYPT. [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2009
This study was done on wetlands of ManzalaLake, northeastern Nile Delta of Egypt, to evaluate the changes of some soil properties after rehabilitation and cropping for 10 years.  Soil samples (0-80 cm depth) were collected randomly from selected sites in

Mineral Classification of Soils Using Hyperspectral Longwave Infrared (LWIR) Ground-Based Data

open access: yesRemote Sensing, 2019
Soil mineralogy is an important factor affecting chemical and physical processes in the soil. Most common minerals in soils—quartz, clay minerals and carbonates—present fundamental spectral features in the longwave infrared (LWIR) region. The

Mineralogy, morphology, and reaction kinetics of ureolytic bio-cementation in the presence of seawater ions and varying soil materials

open access: yesScientific Reports, 2022
Microbially-induced calcium carbonate precipitation (MICP) is a bio-cementation process that can improve the engineering properties of granular soils through the precipitation of calcium carbonate (CaCO3) minerals on soil particle surfaces and contacts ...

Mineralogical associations with soil carbon in managed wetland soils

open access: yesGlobal Change Biology, 2020
AbstractCarbon (C)‐rich wetland soils are often drained for agriculture due to their capacity to support high net primary productivity. Increased drainage is expected this century to meet the agricultural demands of a growing population. Wetland drainage can result in large soil C losses and the concentration of residual soil minerals such as iron (Fe)

Landscape Dynamics in the Caspian Lowlands Since the Last Deglaciation Reconstructed From the Pedosedimentary Sequence of Srednaya Akhtuba, Southern Russia

open access: yesGeosciences, 2018
Surface Kastanozem of the Lower Volga area was first studied as a part of the pedocomplex, with the lower part (148⁻160 cm) formed in Early Khvalynian Chocolate clays (13⁻15 ka), the middle part (100⁻148 cm) in a mixed clay-loess ...

Clay Fraction Mineralogy and Structural Soil Attributes of Two Soil Classes under the Semi-Arid Climate of Brazil

open access: yesLand, 2022
Mineralogical studies are incipient and necessary in the Apodi Plateau, Brazil. This study aimed to evaluate the interrelationship between the mineralogy of the clay fraction and its structural and chemical attributes and to differentiate two important ...
