Salt-Affected Soils & Water Quality
- Salt-Affected Soils in Maharashtra:
- In Maharashtra, salt-affected soils occur extensively across three distinct physiographic and agro-ecological regions:
- Saline Soils: Extensive inland salinity in the vertisols of the Purna Valley (Vidarbha region) and the canal command tracts of Western Maharashtra due to deep waterlogging.
- Alkali (Sodic) Soils: Widespread in black cotton soil basins where high exchangeable sodium percentage ($ESP \gt 15\%$) causes clay dispersion and severe impermeability.
- Coastal Saline Soils: Locally termed Khar lands, covering over 65,000 hectares along the Konkan coastline (Thane, Raigad, Ratnagiri, Sindhudurg) subject to marine tidal ingress.
- Conclusion: (A), (B) and (C) (Option 4).
