Soil resource development institute, Regional office, khulna.

Abstract/ Executive Summary:

The upazila comprises of 14 unions having a population of 1,2,97,544(2001). Three land types namely highland and medium highland and medium low land were identified. The textural classes of soil found were clay loam, clayand peat soil. Eight soil groups were identified. Seven major cropping patterns were found in the upazila. Total 215 soil samples were collected and analyzed and found that the soils of the upazila are deficient in almost all essential nutrient elements except s, zn,ca, Cu, Fe and Mg,Mn. The upazila comprises of highland ,medium highland medium low land, so the area is suitable for upland crops and rice cultivation and some parts remain fallow in rabi season.The area also suitable for shrimp cultivation.Batiaghata upazila was first surveyed in 1989 and updated in 2005.

Keywords: Batiaghata upazila , Land and soil, Soil fertility, Crop suitability,Guide

Location: Batiaghata upazila, Khulna

Start Date: 4-2-2005

End Date: 3-2-2006

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Soil and land resources inventory of Atwari 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:

Batiaghata upazila is situated in the south- western part of khulna district. It lies under the AEZ no. 13( Ganges tidal flood plain ). In this upazila major land type recognized was medium highland comprising 63.3% of total area followed by miscellaneous land comprising 22.1% of the total area. Major textural class also identified was clay covering 31.1% of total area followed by peat soil (25.8%). Seven soil groups were identified namely gopalpur, ishudi,gihur,bajoa, barisal,harta and satla. In medium highland barisal covers major area (33.3%) while in peat soil harta covers major area (15.2%). According to local agro-ecology suitable crops identified were T. Aman,boro,broadcast aus,rabi and kharif vegetables,and shrimp etc. The area is most suitable for transplanted aman . eIGHT major cropping pattern namely rabi vegetables-kharif vegetables,rabi vegetables-jute, boro-TA, FALLOW- TA, Fallow-an, shrimp-TA, SHRIMP-BORO,FALLOW-SHRIMP 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.
