Area of Science:

  • Environmental Science
  • Soil Science
  • Agronomy

Background:

  • Soil properties are critical for land use and rehabilitation, especially in industrial areas.
  • Industrial activities can degrade soil quality, impacting ecosystem health and agricultural productivity.

Purpose of the Study:

  • To assess and compare soil quality across different land-use types (paddy, vegetable, abandoned fields) in an industrial town.
  • To identify key soil properties and contaminants influencing soil quality index (SQI).
  • To provide recommendations for improving soil quality in industrial environments.

Main Methods:

  • Measured 27 physical, chemical, and biological soil properties in topsoil (0-20 cm) from paddy fields (PF), vegetable fields (VF), and abandoned fields (AF).
  • Calculated the Soil Quality Index (SQI) for each land-use type.
  • Utilized a Random Forest model to determine the significance of soil properties and heavy metals on SQI.

    • Main Results:

    • Paddy fields exhibited higher soil organic carbon, nitrogen, CEC, and enzyme activities compared to vegetable and abandoned fields.
    • Abandoned fields showed higher pH and bulk density, while vegetable fields had elevated levels of heavy metals (Hg, Pb, Cd, Cu, Zn).
    • Paddy fields had the highest SQI (0.63), indicating medium to low overall soil quality in the industrial town. Soil biological properties and heavy metals significantly impacted SQI, with β-D-cellobiosidase (CB) being the most influential.

    Conclusions:

    • Integrated agronomic practices are recommended to enhance soil microbial diversity, abundance, and activity.
    • Mitigating heavy metal contamination is crucial for improving soil quality in industrial towns.
    • Targeted interventions focusing on soil biology and contaminant reduction can effectively restore soil health.
