This study attempts to examine the relationship between soil salinity and physico-chemical properties of paddy\nfield soils of Jhilwanja union in Cox�s Bazar, Bangladesh. Data were analyzed by the help of Statistical Package\nfor the Social Sciences (SPSS: version-18) and study area map was prepared by Arc GIS 9.3 software. Present\ninvestigation reveals that soil textural class ranged from sandy to loam, a mean bulk density 1.58 g/cm3\n, and high\nsoil temperature (M = 31.55). Soils were moderately acidic to basic and soil salinity (EC) content comes under\nlow to medium (minimum = 3.10 dS/m, maximum = 7. 24 dS/m) range. The organic matter level exhibited\nabsolutely lower (M = 0.75) than good agricultural soil. Soils of the area represents low in total N (M = 0.08),\nvery low in total P content (M = 0.06), exchangeable Ca (M = 0.0009) were too low and lower content of\nexchangeable Mg (M = 0.26), but high level of exchangeable K (M = 0.57) content. Simple regression analysis\nshowed that there was a significant effect of soil salinity on soil pH, soil temperature, OM, total N, total P,\nexchangeable K and Mg. Repairing coastal embankment (rubber dam), cultivating native high yielding variety,\nusing organic fertilizer, implementing Integrated Soil Nutrient Management (ISNM) and adapting Integrated\nCoastal Zone Management (ICZM) can increase crop production and soil fertility level in study area.
