Soil-water retention in granular soils with varied fine content: a model incorporating adsorption and capillarity

Mechanistic insights into Mn(II) retention and release at soil-water interfaces: Contrasting natural soils and hydrochemical controls.

The retention and release of manganese (Mn) at soil-water interfaces control its subsurface mobility and secondary-remobilization potential, yet their dependence on the combined physicochemical and mineralogical properties of natural soils remains poorly resolved. Here, three compositionally contrasting natural soils,...

Determination of hydraulic conductivity and soil-water characteristic curve in different soil textures by mathematical equations

Measuring soil hydraulic properties is essential in soil science, but direct measurements are often laborious, time-consuming, and costly. Therefore, alternative methods based on mathematical models have gained increasing attention. This study aimed to estimate saturated hydraulic conductivity (Ks) and soil water chara...

Effect of Soil Physical and Organic Matter on Soil Erodibility in Duhok Dam Sub Drainage Basin

Soil erosion is a barrier to achieving sustainable land use especially in semi-arid regions with multiple soil types. This work evaluates the soil erodibility factor (K) at twelve sampling locations in Duhok Dam (Kurdistan Region, Iraq), it investigates impact of key physical and chemical soil properties including bulk...

Influence of soil texture on soil moisture and soil water potential dynamics

Accurate assessment of soil moisture is essential for effective irrigation management, particularly in soils with contrasting textures. Soil water availability is governed by the relationship between volumetric soil water content (θv) and soil water potential (Ψ), which varies with soil texture. The objective of this s...

Development of an Equivalent Loamy Soil and Preparation Technology for Large-Scale Tray Model Testing

Deep soil cementation is widely used for strengthening weak soils; however, the effectiveness of injection mortars largely depends on their penetration ability and interaction with in situ soil conditions. This study aims to develop and validate a methodology for preparing equivalent loamy soil for large-scale tray mod...

Plot‑Scale Assessment of Sewage Sludge and Biochar Effects on Soil Properties, Soil Erodibility, and Runoff in Contrasting Textural Soil
