Multi-Source Pathways of Microplastics in Agricultural Soils

-

 


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.

Image analysis method combined with machine learning for the prediction of soil and air quality

-
      The integration of image analysis methods with machine learning has opened new frontiers in predicting soil and air quality with greater accuracy and efficiency. High-resolution satellite imagery, drone-captured visuals, and hyperspectral imaging are now widely used to extract visual features such as color variations, texture patterns, vegetation health, and land-use changes. These visual indicators are then fed into machine learning models—such as convolutional neural networks (CNNs) and support vector machines (SVMs)—to identify correlations with soil parameters (like moisture, pH, organic content) and air pollutants (like particulate matter, NOx, and CO₂). This data-driven approach enables continuous environmental monitoring, early warning systems, and sustainable land management strategies. The fusion of visual data with predictive analytics not only enhances spatial coverage but also minimizes the need for invasive sampling, offering a scalable solution for sm...

Effects of Long-Term Straw Return and Tillage Practices on Soil Physicochemical Traits and Yield of Waxy Maize

-
  Long-term straw return combined with appropriate tillage practices plays a crucial role in improving soil health and sustaining crop productivity in waxy maize cultivation. Continuous incorporation of crop residues enhances soil organic matter, boosts nutrient availability, and improves soil structure by increasing aggregation and porosity. These changes support better moisture retention and root development, ultimately strengthening plant growth. Conservation tillage systems—such as reduced or no-tillage—further complement straw return by minimizing soil disturbance, reducing erosion, and promoting beneficial microbial activity. Over time, these integrated practices lead to improved soil physicochemical attributes including pH stability, nutrient cycling efficiency, and enhanced cation exchange capacity. As a result, waxy maize grown under long-term straw return and optimized tillage management often demonstrates increased yield potential, greater resilience to environmental str...

Study on soil pressure of loose soil in cohesive soil tunnel considering soil arch effect

-
  The study on soil pressure of loose soil in cohesive soil tunnels considering the soil arch effect focuses on understanding how stress is redistributed around underground openings. In mixed ground conditions, where loose soil is embedded within cohesive strata, the natural formation of soil arches significantly influences lateral and vertical load transfer. By analyzing how arch-shaped stress paths reduce the direct pressure on tunnel supports, researchers can better predict deformation, optimize lining design, and improve the safety of underground structures. The interaction between material properties, overburden depth, and tunnel geometry plays a crucial role in determining the extent and efficiency of the soil arch effect in mitigating soil pressure.
