Abstract/ Executive Summary:

Atghoria upazila is situated in the midle-western part of Pabna district. It lies between 24o02’ and 24o12’ north latitude and 89o09’ and 89o26’ east longitude and covers an area of 18,380 ha. It lies in the physiographic unit of High Ganges Floodplain (AEZ 11) and Low Ganges Floodplain (AEZ 12). The upazila comprises of 5 unions having a population of 136,480 (2001). Four land types namely highland, medium highland, medium lowland, and low land were identified. The textural classes were loam, clay loam and clay. Six soil groups were identified. Nine major cropping patterns were found in the upazila. Total 89 soil samples were collected and analyzed. It was found that the soils of High Ganges Floodplain and Low Ganges Floodplain area are deficient in N, P and Zn. In mapping units 1-4 vegetables, rice, wheat, mustard, onion or annual crops like sugarcane, turmeric, banana, papaya and ginger can be successfully cultivated. Mapping units 5 and 6 are suitable for boro, deep water t-aman, broadcast aman, khesari and mustard. Unit 7 is only suitable for boro, deep water T. aman, and broadcast aman. Fertilizer recommendations for suitable crops are given. The upazila was first surveyed in 1985 and updated in 2003.

Location: Atgharia Upazila, Pabna

Start Date: 01-01-2003

End Date: 30-12-2006

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Atgharia Upazila

2. Soil fertility assessment and fertilizer recommendation.

3. Crop suitability assessment.

4. Preparation of land and soil resource utilization guide with soil and landform map.

Methodology:

Field survey was conducted on the basis of semi-detailed soil survey method. Interpretative soil and landform map was prepared using 1:50,000 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 patterns, soil management data were collected by physical observations and interviewing the farmers. Soil samples were analyzed for fertility assessment. Crop suitability for each land type was determined. Fertilizer recommendations for suitable crops were made. Final soil and landform map was made from the interpretative field map through verification by ground truthing and field checks. After compiling physical and chemical data sets the land and soil resource utilization guide was prepared.

Funding Source:

Budget: 150000

Total Budget (Tk.) : 150000

Achievement/Findings:

Major land types recognized were highland (32.7%) and medium highland (36.6%). Major textural classes also identified were clay (34.2%), loam (24.7%) and clay loam (22.0%). Six soil groups were identified namely, Sara, Gopalpur, Ishwardi, Ghior, Batra and Made land. In highland and medium highland Sara, Gopalpur and Ishwardi existed. Suitable crops identified were jute (deshi, tosa), rice (boro, T. aus, B. aus and T. aman), rabi maize, rabi cotton, groundnut, soybean, wheat, cabbage, cauliflower, spinach, red amaranth, rabi chilli, mustard, brinjal (rabi and kharif), mango, jackfruit, coconut, and betel nut. Kaun, potato, onion, garlic, mung bean, muskalai, kharif vegetable, watermelon, pineapple, ginger, turmeric, and banana were identified as moderately suitable. Six major cropping patterns were found e.g. Wheat/Mustard/ Khesari/Lentil/Onion/Garlic-Aus/Til/Jute-T. aman; Potato/Radish/ Beans/Cabbage/Cauliflower/Tomato/Chilli- Brinjal/Snake gourd/ Laddy’s finger/ Chilli; Wheat/Mustard/ Khesari/Lentil/Onion/Garlic-Fallow-T. aman; Wheat/Mustard/ Khesari/Lentil/Onion/Garlic-Aus/Til/Jute/Chilli-Fallow. Boro (Modern)-T. aman (modern). Fertilizer recommendations for suitable crops are given. 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.
