Soil Resourse Development Institute District office, Dinajpur

Abstract/ Executive Summary:

Nababganj upazila lies between 25^o18^/ and 25^o34^/north latitude and 88^o59^/ and 89^o13^/east longitude and covers an area of 31,480 ha. It lies in the physiographic unit of Barind Tract & Tista River Floodplain. The upazila comprises of 9 unions having a population of 2,04,351 (2001). Three land types namely highland, medium highland and medium lowland were identified. The textural classes were sandy loam, loam, clay loam and clay. Fifteen soil groups were identified. Total 134 soil samples were collected and analyzed. It was found that the soils of this area are deficient in N, Ca Zn and B . In each union rice, jute, rabi vegetables can be successfully cultivated.

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Nababganj 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:

According to local agro ecology suitable crop identified were boro rice, broadcast aman, onion, potato, brinjal, tomato, mustard. Major cropping patterns namely rabi vegetables- kharif vegetable; potato/wheat/maize – fallow- broadcast aman, boro-fallow-broadcast aman, boro-fallow-fallow were identified. 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.
