Abstract


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