Isolation effect of periodic wave impeding block in layered transversely isotropic soil

-

 



     The isolation effect of a periodic wave-impeding block in layered transversely isotropic soil is a vital area of study in geotechnical and earthquake engineering. Periodic wave-impeding blocks (WIBs), typically designed as arrays of rigid or semi-rigid inclusions, are implemented to disrupt the propagation of seismic or vibrational waves through soil layers. In layered transversely isotropic soils—where properties like stiffness and permeability vary with direction but remain uniform within each layer—the wave behavior becomes more complex due to the anisotropic nature of the medium. The presence of WIBs introduces bandgaps, frequency ranges where wave transmission is significantly attenuated or even eliminated. Numerical and analytical studies reveal that the effectiveness of WIBs strongly depends on the material anisotropy, layering sequence, wave type, and incident angle. Such systems prove beneficial in reducing ground-borne vibrations near sensitive infrastructures like subways, pipelines, or precision manufacturing facilities. The interaction between periodic structures and anisotropic soil layers enables more targeted wave mitigation, improving the design of seismic isolation systems in urban and industrial areas.

Linking Soil Properties and Bacterial Communities with Organic Matter

-
       Vegetation succession plays a crucial role in shaping soil properties and bacterial communities, ultimately influencing organic matter carbon dynamics. As plant communities evolve, they contribute varying amounts of organic inputs such as root exudates and leaf litter, which alter soil physicochemical characteristics, including pH, nutrient availability, and moisture content. These changes, in turn, influence microbial diversity and composition, as bacterial communities adapt to the shifting soil environment. Soil bacteria play a vital role in organic matter decomposition, carbon sequestration, and nutrient cycling, thereby regulating carbon fluxes in the ecosystem. Understanding the intricate relationships between soil properties, microbial communities, and organic matter carbon during vegetation succession is essential for predicting ecosystem carbon storage potential and designing sustainable land management strategies. #SoilProperties #BacterialCommunitie...

N2O Emissions from Soil in Tomato Production

-
     The application of biochar, biogas slurry, and dicyandiamide (DCD) in soil management plays a significant role in mitigating nitrous oxide (N₂O) emissions while enhancing soil fertility and crop productivity. In protected tomato cultivation, these amendments influence nitrogen dynamics and microbial activities, directly affecting greenhouse gas emissions. Biochar improves soil structure, enhances water retention, and provides a stable carbon source, leading to reduced N₂O emissions by promoting complete nitrification and denitrification processes. Biogas slurry, a nutrient-rich organic amendment, supplies readily available nitrogen for plant uptake, reducing nitrogen losses and gaseous emissions. Meanwhile, DCD, a nitrification inhibitor, slows down the conversion of ammonium to nitrate, effectively minimizing N₂O production. The combined use of these amendments has shown promising results in maintaining soil health, increasing nitrogen use efficiency, and reducing t...

Trade-off between organic and inorganic carbon in soils under alfalfa-grass-cropland rotation

-
        The trade-off between organic and inorganic carbon in soils under an alfalfa-grass-cropland rotation is influenced by land management practices, soil properties, and carbon cycling dynamics. Organic carbon, primarily derived from plant residues and root exudates, enhances soil fertility, microbial activity, and water retention. In contrast, inorganic carbon, mainly in the form of carbonates, contributes to long-term carbon sequestration but has limited benefits for soil fertility. The rotation of alfalfa and grasses with cropland affects the balance between these carbon forms by influencing decomposition rates, microbial activity, and soil pH. While alfalfa and grasses enhance organic carbon input through biomass accumulation and root turnover, cropland phases may accelerate organic carbon mineralization due to tillage and reduced plant cover. Proper management strategies, such as reduced tillage, cover cropping, and optimized fertilization, can help maintai...
