Abstract/ Executive Summary:

Belabo Upazila is situated in the north-eastern part of Narsingdi district. It lies between 24º02´ and 24º12´ north latitude and 90º46´ and 90º58´ east longitude and covers an area of 11,768 ha. It lies in the physiography of Madhupur Tract (AEZ 28) and Old Brahmaputra Floodplain (AEZ 9). The upazila comprises of 7 unions having a population of 164,038 (2001). Four land types namely highland, medium highland, medium lowland and lowland were identified. The textural classes were sand, sandy loam, loam, clay loam and clay. Eleven soil groups were identified. Total 85 soil samples were collected and analyzed. It was found that soils of Madhupur Tract and Old Brahmaputra Floodplain of this upazila are deficient in N, P, K and N, P, S respectively. Eight cropping patterns were found in the upazila. Fertilizer recommendations for suitable crops are given. Belabo upazila was first surveyed in 1990 and updated in 2013.

Keywords: Belabo Upazila, Land types, Soil groups, Crops, Cropping patterns,Guide

Location: Belabo Upazila, Narsingdi District

Start Date: 01-01-2009

End Date: 30-04-2013

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Belabo 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, although more samples were taken wherever necessary according to complexity of soils. 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:

1. Government

Budget: 150000

Total Budget (Tk.) : 150000

Achievement/Findings:

Major land types recognized were highland (29.15%), medium highland (35.18%) and medium lowland (14.92%). Major textural classes identified loam (26.31%), clay loam (34.14%) and clay (19.26%). Major soil groups identified Tejgaon, Belabo, Kalma, Khilgaon, Sonatala, Silmandi and Naraibag. Suitable crops were Jute (deshi, tosa), Boro rice (HYV), T. Aman rice (HYV and LIV), Aus (HYV and LIV), Deep-water Aman, wheat, sugarcane, maize (rabi and kharif), groundnut (rabi and kharif), mustard, rabi soybean, chilli, cabbage, cauliflower, brinjal, masur, gram, mango, jackfruit and coconut. Major cropping patterns were Boro rice-Fallow (F)-T. Aman rice (30.86%); Boro rice-F-F; Rabi vegetables-kharif vegetables; Ginger/turmeric/sugarcane/pineapple; Banana/guava/jackfruit/lemon and Jute-F-T. Aman rice. Fertilizer recommendations for 59 existing and potential crops of the upazila at high and medium yield goals and for 89 crops at high yield goal are given. Soils of Madhupur Tract and Old Brahmaputra Floodplain of this upazila are deficient in N, P, K and N, P, S respectively. This guide can be used for determining flood, drought, water-logging and soil erosion. Demonstration site selection for technology transfer can be done with the help of this guide. Upazila land and soil resource's carrying capacity can be estimated which would help in determining food deficit or surplus situation.
