Preparation of Upazila Land and Soil Resource Guide, Bamna

Md. Nazrul Islam
Principal scientific officer (Retd)
Soil resource development institute, District office, Patuakhali

Abstract/ Executive Summary:

The upazila comprises of 10 unions having a population of 1,40,043 (2001). Three land types namely highland, medium highland and medium low land were identified. The textural classes of soil found were clay,clay loam and loam. Four soil groups were identified. Six major cropping patterns were found in the upazila. Total 74 soil samples were collected and analyzed and found that the soils of the upazila are deficient in almost all essential nutrient elements except Ca, Mg, S,B, Cu, Fe and Mn. The upazila comprises of highland and medium highland and medium low land, so the area is suitable for Taman, Taus, rabi vegetables and other upland crops. The climate, land form and geo-morphological environment of the area are also suitable for mung bean .Bamna upazila was first surveyed in 1996.

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

Location:

Start Date: 5-3-1994

End Date: 4-3-1995

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Soil and land resources inventory of Bamna 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:

Bamna sadar upazila is situated in the western part of Barguna district. It lies under the AEZ no. 13 (Ganges tidal floodplain. In this upazila major land type recognized was medium highland comprising 62.0% of total area followed by miscellaneous land comprising 28.7% of the total area. Major textural class also identified was clay covering 44.9% of total area followed by clay loam (24.7%). Four soil groups were identified namely Jhalakathi, Barisal, ramgati, and ganges tidal silty alluvium. In medium highland barisal covers major area (36.7%) while in medium highland Jhalakathi covers major area (25.5%). According to local agro-ecology suitable crops identified were rabi vegetables, chilli, groundnut, Taus, Taman, khesari, mungbean, sweet potato etc. The area is most suitable for Taman, Taus and rabi vegetables. Six major cropping pattern namely Mugbean/groundnut-fallow-Taman, mung bean/kheari/chill/sweet potato- fallow- Taman, mung bean/chilli/khesari-Taus- Taman, Mung bean/khesari/chilli/sweet potato-Taus, Fallow-Taus-Taman, fallow-fallow-Taman 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.
