Analysis of salinity level in coastal soil: a case study on kalinchi mauza at satkhira district of Bangladesh

Salinity increase has been one of the major problems for traditional agricultural practices in coastal Bangladesh for several decades, but very few studies have been conducted on impact of salinity on agriculture in this area. This study tries to trace out salinity level and causes in coastal soil. The research was performed around Kalinchi mauza under Shyamnagar Upazila, Satkhira district in Bangladesh. This area was selected because it is one of the most vulnerable areas for high exposure to salinity intrusion and widespread many problems. The study was collected primary and secondary data different methods had been adopted which were soil sample collection, water and soil test in field, field observation and survey, FGD, questioner survey, mauza map, satellite image, other secondary sources and 100 personal interviews. In the case of data analysis; Parameter, Geo-spatial analysis, Salinity Metter, Microsoft tools, Geo-spatial analysis in Arc GIS systems have been used. Parameter ECe with HANNA Model HI 933100 conductivity Meter and pH with HANNA HI 9210N pH Meter have been used for salinity measuring. The findings of the research show that the severity of salinity problem in study areas increases with the desiccation of the soil.
