The total area of Bangladesh was divided into three categories. These were highland, medium highland and low land. Highland, medium highland and low land covered 29%, 35% and 21% of the total land in Bangladesh, respectively. Others 15% land covers by river, urban and homesteads etc. About 99% areas of the Chittagong hill tract and Bandarban were belonging to high land category. The major part of Bangladesh had medium high land which is very much preferable to agriculture. This study was illustrated by different maps where most part of Bangladesh consists of agricultural land along with haors, baors and beels. Major parts of forest were found in Khulna, Bagerhat, Satkhira, Potuakhali, Cox’s Bazaar, Rangamati, Bandarban, Khagrachari, Gazipur, Tangail, Mymensingh, Rangpur and Sylhet district of Bangladesh. Mangrove forest was found in Khulna, Bagerhat and Satkhira district in Bangladesh. Roughly it was found that, baors and beels were present in south-western region of Bangladesh. On the other hand, haors were located in Sylhet, Sunamgonj, Hobigonj and Moulovibazar district. However, Bangladesh had a natural lake which was located in Rangamati district of hill tract. Kustia, Pabna, Dinajpur, Rangpur, Dhaka, Narayangonj, Khulna, Jessore, Sylhet, Rajshahi, Munshigonj, Norshindi, Comilla, Chittagong were the major urban and industrial zone, and Cox’s bazaar and Chittagong districts were the sea salt production zone. It was found that Sylhet, Moulovibazar, Hobigonj, Chittagong and Panchagorh district had a lot of tea garden which provide our country’s tea demand. Fourteen types have been identified on floodplain areas, one on hilly areas and rest of them are terrace lands. The agricultural potential of non-calcareous brown flood plain soils were mainly moderate to low and non-calcareous grey floodplain soils were the most extensive soils in the country.
The exploration of mapping of different important parameters of soils in Bangladesh has done using GIS in the present study. Data collection, shapefile preparation and finalizing the respective maps of various important soil types in Bangladesh etc. are the major steps for this research. With such kind of research, it can be concluded that Bangladesh has a very wide diverse quality of soil characteristic with soil formation, texture, pH, salinity, toxicity, soil nutrient, soil land types as well as topography. This research work can be the remarks of the present soil quality and diversity of soil all over Bangladesh. It would be helpful to explore the overall situation of different soil types and their important properties through distinguished maps.
