Senior Scientific Officer
Soil Resourse Development Institute, District Office, Jamalpur

Abstract/ Executive Summary:

Sherpur Sadar upazila lies between 24^o54’ and 25^o06’ north latitude and 89^o53’ and 90^o09’ east longitude and covers an area of 35,781 ha. It lies in the physiographic unit of Old Brahmaputra Floodplain, Young Brahmaputra Floodplain & Active Brahmaputra Floodplain. The upazila comprises of 13 unions and 1 Paurosova having a population of 3,81,419(1991). Four land types namely highland, medium highland, medium lowland, and low land were identified. The textural classes were sandy, sandy loam, loam, clay loam and clay. Eleven soil groups were identified. Twelve major cropping pattern were found in the upazila. Total 191 soil samples were collected and analyzed. It was found that the soils are deficient in N, P and K. In each union vegetables, rice, jute, sugarcane can be successfully cultivated. Sherpur Sadar upazila was first surveyed in 1986 and updated in 2007.

Keywords: Sherpur Sadar, Land and soil, Soil fertility, Crop suitability

Location: Sherpur Sadar upazila, Sherpur District

Start Date: 01-11-2007

End Date: 31-10-2008

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Sherpur Sadar upazila

2. Soil fertility assessment and fertilizer recommendation

3. Crop suitability assessment

4. Preparation of land and soil resource utilization guide with soil and land form map.

Methodology:

Field survey was conducted on the basis of semi-detailed soil survey method. Interpretative soil and land form map was prepared using 1:50000 aerial photographs. Soils were investigated following a catena and composite top soil samples were collected. The sampling frequency were 1 (one) sample per 200 ha. During survey, crops, cropping pattern, soil management data were collected by interviewing the farmers. Soil samples were analyzed for fertility assessment. Crop suitability for each land type was determined. Fertilizer recommendation for suitable crops was made. After compiling physical and chemical data sets the land and soil resource utilization guide was prepared.

Achievement/Findings:

Sherpur Sadar upazila is situated in the south-western part of Sherpur district. It lies under the AEZ No. 7 (Active Brahmaputra-Jamuna Floodplain) AEZ No. 8 (Young Brahmaputra & Jamuna Floodplain) and AEZ No. 9 (Old Brahmaputra Floodplain). In this upazila major land type recognized was medium highland comprising 35.4% of total area followed by highland comprising 32.0% of the total area. Major textural class also identified was loam covering 52.5% of total area followed by clay (17.0%) and clay loam (10.5%). Eleven soil groups were identified namely, Nakla, Sherpur, Sonotala, Silmondi, Ghatail, Balina, Melandhah,Dhamrai, Bararchar Brahmaputra silty alluvium, and Brahmaputra sandy alluvium. Among twelve major cropping patterns, Boro-Fallow-Transplanted Aman covers 10,805ha; Boro-Fallow-Fallow covers 5,880ha; Mustard-Boro-Transplanted Aman covers 2,598ha; Rabi crops-Aus-Transplanted Aman covers 2,068ha of total area. Fertilizer recommendation for suitable crops are given in the guide. This guide can be used for determining flood, drought, landslide, soil erosion, river bank erosion. Demonstration site selection for technology transfer and local level development planning can be done with the help of this guide. Upazila land and soil resources carrying capacity can be estimated which would help in determining food deficit or surplus of the area.
