Multiscale Soil Investigations: Physical Concepts And Mathematical Techniques [PDF]

, 2008
Soil variability has often been considered to be composed of “functional” (explained) variations plus random fl uctuations or noise. However, the distinction between these two components is scale dependent because increasing the scale of ...

Water reuse for irrigated agriculture in Jordan: challenges of soil sustainability and the role of management strategies [PDF]

, 2010
Reclaimed water provides an important contribution to the water balance in water-scarce Jordan, but the quality of this water presents both benefits and challenges. Careful management of reclaimed water is required to maximize the nutrient benefits while

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...

THE GEOLOGICAL FIELD APPROACH TO THE ARCHAEOLOGICAL SITE YARD

EQA, 2017
The main duties of the geologist’s contribution to the field work in the archaeological excavation sites are briefly recalled. The need for a preliminary conceptual and pragmatic approach for a correct understanding of the local context of each field ...

Soil Structure and Mixing Controls on Water‐Rock Contact: Implications for Enhanced Weathering

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Enhanced weathering (EW), the addition of finely ground silicate rock powder (RP) to soil, has emerged as a promising carbon removal strategy. However, quantifying weathering rates in soils remains challenging, as most continuum‐scale EW models do not adequately account for the fraction of RP surface area (SA) that is wet at a given soil ...

Uses of volcanic ash beds in geomorphology [PDF]

, 1967
In geomorphology air-fall volcanic ashes possess high value as marker beds. These have proved particularly useful in studies associated with infilling of flood plains, fan building, terrace correlation and chronology, erosion, shoreline and sea level ...

Characterization of Preferential Flow Occurrence During Freeze‐Thaw Cycles

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Preferential flow (PF) critically influences water and energy dynamics in frozen soils, yet its quantification and mechanisms remain poorly understood due to observational challenges. This study proposes a novel method to identify PF by analyzing soil temperature response times across depths.

Spectral Mixture Modeling of an ASTER Bare Soil Synthetic Image Using a Representative Spectral Library to Map Soils in Central-Brazil

AgriEngineering, 2023
Pedological maps in suitable scales are scarce in most countries due to the high costs involved in soil surveying. Therefore, methods for surveying and mapping must be developed to overpass the cartographic material obtention.

Contrasting Trends in Cold‐Season Daily Soil Temperature With Climate Warming in Snow‐Affected Settings

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Soil temperature is inextricably linked with hydrological and biogeochemical processes. This study analyzes the long‐term minimum soil temperature (TSMIN) trends at 526 stations located in snow‐affected regions of CONUS. Long short‐term memory (LSTM) are implemented to extend TSMIN beyond the observational period, producing long‐term (1981 ...

Exploitation of Magnetic Susceptibility Data for Soil Stability Analysis: A Watershed Study of the Oued Ghiss Dam in the Central Rif, Morocco [PDF]

E3S Web of Conferences
The water erosion of soil in northern Morocco raises significant concerns due to its potential impact on the sustainability and productivity of the land. The objective of our study is to evaluate water erosion by utilizing magnetic susceptibility of soil
