Soil salinity impedes agricultural production, threatens global food security and agricultural profits. Soil salinity is a global issue and the accurate assessment of salt affected areas can assist in combating global climate change, effectively manage and utilize limited land and water resources. Landsat series of the multispectral remote sensing provides the potential for frequent surveys for soil salinization at various scales and resolutions. For this research, twenty tiles of Landsat 8 imagery between 2018 and 2019 were used to generate the soil salinity index map for the study area. The result revealed the salinity index status for all the areas investigated. Reclamation of salt affected land and management practices to curb soil salinity is highly recommended.
