  The vertical distribution and multi-source pathways of microplastics in agricultural soils have emerged as a critical area of environmental concern. Microplastics, originating from diverse sources such as agricultural plastic mulches, sewage sludge, irrigation with contaminated water, and atmospheric deposition, can infiltrate soil layers through physical, chemical, and biological processes. Their vertical migration is influenced by soil structure, texture, bioturbation, and leaching, leading to their accumulation not only at the surface but also in deeper soil horizons. This hidden contamination poses potential threats to soil health, microbial communities, crop productivity, and groundwater quality. Understanding the dynamics of microplastic distribution and transport in soils is essential for developing effective mitigation strategies and promoting sustainable agricultural practices.

  The differential response of soil characteristics and extracellular enzyme activities along an altitude gradient in a subtropical forest ecosystem highlights the complex interactions between climatic conditions, microbial activity, and soil properties. As altitude increases, changes in temperature, moisture, and vegetation composition significantly influence soil pH, organic carbon, nitrogen content, and microbial biomass. These shifts are closely linked to variations in extracellular enzyme activities responsible for nutrient cycling, such as β-glucosidase, urease, and phosphatase. The study underscores the role of altitude as a key ecological factor regulating soil biochemical processes and microbial functioning, which is essential for understanding ecosystem dynamics and predicting responses to climate change in mountainous regions.

  The influence of plant roots on soil preferential paths for infiltration plays a critical role in shaping water movement in the Loess Plateau, a region known for its fragile ecology and deep loess deposits. Vegetation typical of this area, such as Robinia pseudoacacia , Caragana korshinskii , and various native grasses, contributes to the development of root channels that enhance preferential flow pathways. These root-induced macropores allow rainwater to bypass the compacted soil matrix, improving water infiltration efficiency and reducing surface runoff and erosion. Over time, these biological structures not only increase soil moisture retention but also promote soil stability and ecosystem resilience. Understanding the dynamic interaction between root systems and infiltration pathways is essential for designing effective soil and water conservation strategies in semi-arid environments like the Loess Plateau.

  The interaction between soil and building structures significantly influences the dynamic earth pressure exerted on basement walls, particularly during seismic events or heavy loading conditions. When subjected to dynamic forces, the behavior of the soil mass changes, affecting how loads are transmitted to retaining structures. This interaction depends on factors such as soil type, stiffness, damping properties, wall flexibility, and foundation characteristics. Accurate assessment of soil-structure interaction is crucial for designing basement walls that can withstand dynamic pressures without failure. Ignoring this interaction can lead to underestimation or overestimation of earth pressures, resulting in unsafe or overly conservative designs. Advanced analytical and numerical modeling techniques, including finite element analysis, are often employed to simulate the complex behavior of soil-building systems under dynamic loading. Understanding these interactions enhances the safe...

  Satellite remote sensing has emerged as a powerful tool for monitoring soil texture in regions dominated by black soil, particularly across the Deccan Plateau. By using data from multispectral and hyperspectral sensors, researchers can detect variations in soil properties such as clay content, moisture levels, and organic matter. These factors are crucial in understanding the structure and fertility of black soils, which are known for their high moisture retention and nutrient-rich composition. Monitoring these parameters from space allows for real-time assessments of how soil texture affects crop growth, enabling farmers and agronomists to make informed decisions regarding crop selection, irrigation practices, and soil management. This technology plays a vital role in precision agriculture by improving productivity, conserving resources, and ensuring long-term soil health in black soil regions.

  The evaluation of advanced soil models for the cyclic soil-structure interaction (SSI) of integral bridges is crucial for improving the accuracy of structural performance assessments under repeated loading conditions. Integral bridges, which lack expansion joints, rely heavily on the interaction between the superstructure and the surrounding soil to absorb and redistribute stresses. During thermal expansion and contraction cycles, this interaction becomes highly nonlinear, making traditional modeling approaches inadequate. Advanced soil constitutive models—accounting for strain hardening, hysteresis, and soil degradation—offer a more realistic representation of cyclic behavior. By integrating these models into finite element analyses, researchers can predict bridge response more accurately, optimize design, and enhance long-term durability. This research supports resilient infrastructure by reducing maintenance costs and mitigating structural vulnerabilities related to soil behav...

  The evolution of thermal conductivity in sand-clay composites under one-dimensional compression is a critical subject in geotechnical and environmental engineering. As pressure increases, the rearrangement of soil particles, reduction in porosity, and redistribution of moisture content significantly influence the heat transfer capabilities of the composite. Initially, thermal conductivity tends to increase with compression due to improved particle contact and reduced air voids, which are poor conductors of heat. However, the rate of increase may vary depending on factors such as clay content, water saturation level, and grain size distribution. Understanding these variations is essential for designing effective underground thermal energy storage systems, evaluating soil behavior under load, and predicting heat transfer in layered soils in various engineering applications.
