Preparation of Upazila Land and Soil Resource Guide, Nalchiti

Soil Resource Development Institute, District office, Barisal

Abstract/ Executive Summary:

Nalchiti upazila lies between 22^o37 and 22^o48 north latitude and 90^o16 and 90^o32 east longitude and covers an area of 32.649 ha. It lies in the physiographic unit of Ganges tidal floodplain. The upazila comprises of 10 unions and 1 pouroshava having a population of 5,31,999 (2001). Four land types namely highland, medium highland, medium low land and low land were identified. The textural classes of soil found were clay, clay loam and loam. Ten soil groups were identified. Five major cropping patterns were found in the upazila. Total 103 soil samples were collected and analyzed and found that the soils of the upazila are deficient in almost all essential nutrient elements except Ca, S,B, Mg, Cu, Fe and Mn. The upazila comprises of highland , medium highland and medium low land, so the area is suitable for rabi vegetables, kharif vegetables,chilli, khesari,mung bean, sweet potato, Taman, Taus and other upland crops. The climate, land form and geo-morphological environment of the area are also suitable for boro rice cultivation. Nalchiti upazila was first surveyed in 1989 and updated in 2008.

Keywords: Nalchiti upazila, Land and soil, Soil fertility, Crop suitability

Location: Nalchiti upazila, Jhalakathi

Start Date: 00-00-2008

End Date:

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. To invent soil and land resources of nalchiti Upazila

2. To assess soil fertility for fertilizer recommendation

3.To assess crop suitability

4. To prepare 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:

In this upazila major land type recognized was medium highland comprising 52.2% of total area followed by miscellaneous land comprising 31.3% of the total area. Major textural class also identified was clay loam covering 37.3% of total area followed by loam (25.7%). Ten soil groups were identified namely Jhalakathi, barisal,ramgati,sara,kalabadar,gopalpur, hijla, muladi, mahendigong,ganges silty alluvium. In medium highland jhalakathi covers major area (12.1%) while in medium highland gopalpur covers major area (12.8%). According to local agro-ecology suitable crops identified were rabi vegetables, kharif vegetables, boro, Taman, T. aus etc. The area is most suitable for T. aman,T. aus and other upland crops. Five major cropping pattern namely rabi vegetables- kharip vegetables, boro-fallow-Taman,chilli/khesari/sweet potato/mustard/mung bean-T aus-T aman,Fallow-T Aus-T. Aman,Boro-Fallow-Ffallow were identified. Fertilizer recommendation for suitable crops is given in the guide. The guide can be used for determining flood and drought, 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.
