Salinity in soils of coastal Bangladesh, one of the foremost challenges for agriculture, differs considerably owing to various factors. But, the salt dynamics of coastal soils has not been experimented comprehensively despites its significance in coastal agriculture. In the present study, we looked at such variability along four locations of Batiaghata upazilla under Khulna district, Bangladesh. Soil samples were collected at weekly intervals from January 2011 to June 2011. Descriptive statistics was used to calculate the salinity levels (dS m-1) and moisture content (%). Regression analysis was done to mark the relationship between those two aspects. Our results disclosed that soil salinity gradually increased from January onwards and reached the maximum in April. Thereafter it decreased gradually and touched the bottom most during June. A negative and linear correlation was established between soil salinity levels and soil moisture contents, specifying the dependency of salinity on soil wetting (or drying). This inquiry, hence, may subsidize to existing policies on land management in southwestern coastal Bangladesh.
