Geospatial Assessment and Reclamation Dynamics of Salt-Affected Soils in Uttar Pradesh

Abstract	Soil salinity and sodicity are major land degradation processes that threaten agricultural sustainability, soil health, and food security. Salt-affected soils modify physicochemical properties, disrupt plant-water relations, and reduce nutrient availability, thereby constraining crop productivity. In India, these soils occupy nearly 6.7 million hectares and are unevenly distributed, with large concentrations in the Indo-Gangetic plains. Uttar Pradesh contains a significant share, dominated by sodic and saline-sodic soils characterized by high pH and elevated exchangeable sodium percentage. Excess sodium induces clay dispersion, structural degradation, and reduced hydraulic conductivity, severely limiting infiltration and crop establishment [1].
