Abstract	Soil samples were collected during 6 to 10 April 2015 at thirteen different locations from the Sundarban mangrove forests (SMF) of Bangladesh and 7 physico-chemical properties were analyzed. Mean soil pH of SMF soil was slightly alkaline, 7.34, although the minimum value was found to be acidic, 6.2 and maximum was 8.6. Salinity of soils of SMF showed wide range of variations with the mean value was 7.79‰ and minimum and maximum values were 2.06‰ and 24.25‰ respectively. We have proposed ecological zonations in soil habitats of SMF according to Iversen (1936) based on salinity. It has been found that some locations should be considered as mesohaline zones and some as mesohaline to polyhaline zones which were previously designated as oligo-mesohaline zones and polyhaline zones by other workers. The mean values of other soil variables of SMF were moisture content (25.70%), conductivity (12.172 mS/cm), organic carbon (0.833%), N (1.72%), P (0.022%). Salinity showed significant positive correlation with N (r = 0.444, p = 0.000) and OC (r = 0.230, p = 0.019) and significant negative correlation with moisture (r = -0.309, p = 0.001), pH (r = -0.508, p = 0.000) and P (r = -0.939, p = 0.008). Highly significant difference was present in case of salinity among the locations (F = 15.52, P = 0.000) and layers (F = 9.23, P = 0.000) of SMF. Significant differences were present in pH among the locations of SMF (F = 22.11, P = 0.000). Principle component analysis (PCA) showed the cluster form between conductivity and salinity. The present study provides present status of edaphic features with changes in ecological zonations of Sundarban mangrove forests.
