Soil Resource development institute,regional office khulna.

Abstract/ Executive Summary:

Fultala upazila lies between 22o54 and 23o01 north latitude and 89o23 and 89o31 east longitude and covers an area of 7438 ha. It lies in the physiographic unit ofganges floodplain, ganges tidal floodplain and gopalgong- khulna bills. The upazila comprises of 4 unions having a population of 1,18,394 (2001). three land types namely highland, medium highland and medium lowland were identified. The textural classes of soil found were loam, clay loam and clay . Nine soil groups were identified. Six major cropping patterns were found in the upazila. Total 46 soil samples were collected and analyzed and found that the soils of the upazila are deficient in almost all essential nutrient elements except k,s,B,Ca,Mg,Cu, Fe and Mn. The upazila comprises of highland and medium highland, medium low land, so the area is suitable for rice and upland crops. As saline water is available in this upazila,The area is also suitable for shrimp cultivation.Fultala upazila was first surveyed in 1988 and updated in 2007.

Keywords: Fultala, Land and soil, Soil fertility, Crop suitability

Location: Fultala upazila, khulna

Start Date: 1-1-2007

End Date: 31-12-2008

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Soil and land resources inventory of fultala 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 soils were collected. The sampling frequency was 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:

Fultala upazila is situated in the north- western part of khulna district. It lies under the AEZ no. 11,13 and 14 (Ganges floodplain, Ganges Tidal floodplain and Gopalgong-Khulna bills). In this upazila major land type recognized was medium highland comprising 32.9% of total area followed by miscellaneous land comprising 30.8% of the total area. Major textural class also identified was clay covering 38.4% of total area followed by miscellaneous land(30.8%). Six soil groups were identified namely Ishwardi, Ghior,Barisal,Harta,Satla,Gopalpur and Sara. In medium low land Harta covers major area (15.8%) while in medium highland Ishwardi covers major area (13.5%). According to local agro-ecology suitable crops identified were boro, T. Aamn, Aus, jute, Lentil, vegetables, shrimp etc. The area is most suitable for rice, shrimp and other upland crops.Six major cropping pattern namely rabi vegetables-kharif vegetable; boro-shrimp, boro- T. Aamn; fallow-T.aman, lentil/mustard/fallow-aus/jute-Taman; Boro-B.Aman/Deep Water T.aman, rabi vegetables- kharif vegetables were identified. Fertilizer recommendation for suitable crops is given in the guide. The guide can be used for determining flood and drought, salinity, soil erosion, river bank erosion affected area. 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.
