Abstract/ Executive Summary:

The BINA-sub-station was surveyed in detail following standard method. It lies between 22^o45' north latitude and 89^o07' east longitude which is about 6 km north-west of Satkhira town. It lies under physiographic unit-Ganges Tidal Floodplain. About 82% of the area is subjected to shallow flooding during monsoon. Textural classes ranges from silty clay loam to clay. Three soil series namely Barisal, Pirojpur and Daulatpur have been identified. The soils have been mapped into 5 mapping units depending on phases. The soils are saline varying in degrees. In all the series N was found limiting. The area was divided into two land capability classes and was mapped into 3 mapping units. The soils are Inceptisols.

Keywords: BINA sub-station, Deatiled soil survey, Satkhira

Location: BINA Sub-Station, Satkhira

Start Date: 1-5-2000

End Date: 15-5-2000

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

To increase efficiency in planning experimental programs and thereby minimize the errors in interpretation of results.

Methodology:

The method of survey of the sub-station was based on high intensity survey i.e. detailed soil survey. The survey was carried out on the basis of detailed field observations of the soils, topography, and other environmental characteristics and collecting of representative soil samples for chemical analyses.During field survey mouza map (16"=1 mile), soil association map (1:125,000) of RSS Reports, Upazila Land and Soil Resource Utilization Guide of Satkhira sadar, Toposheet (1:50,000), aerial photographs (1:30,000), Soil and landform Map (1:50,000) were used as base materials. Grid method was followed for field observation. After every 30 meters along and apart the traverse line soils were checked by digging minipits with auger and spade. Across the catena traverse routes were directed north to south. In total 30 horizon wise soil samples were collected from 3 representative soil pedons and 8 composite topsoil samples were collected from identified soil series. Soil samples were analysed in the laboratory following standard methods. A Soil Map and a Land Capability Map (1:4000) were prepared.

Budget: 1,00,000.00

Total Budget (Tk.) : 1,00,000.00

Achievement/Findings:

The sub-station lies under physiographic unit-Ganges Tidal Floodplain. A tidal canal crosses the sub-station. The entire area is underlain by recent and sub-recent alluvium which have been deposited under either tidal or meandering condition with in last 1000 years. About 82% of the area is subjected to shallow flooding during monsoon. Tidally deposited sediments are predominantly clayey in nature with shallow ground water table. Textural classes ranges from silty clay loam to clay. Three soil series namely Barisal, Pirojpur and Daulatpur have been identified. The soils have been mapped into 5 mapping units depending on phases. The soils are saline varying in degrees: Barisal series being slightly to moderately saline, Pirojpur series being moderately saline and Daulatpur series being slightly to strongly saline. In all the series N was found limiting. The area was divided into two land capability classes and was mapped into 3 mapping units. The soils are Inceptisols.
