Abstract/ Executive Summary:

Karimgonj upazila lies between 24^o22^?and 24^o32^?north latitude and 90^o48^?and 91^o01^?east longitude and covers an area of 19573 ha. It lies in the physiographic unit of “Old Brahmaputra FloodPlain” and “Surma-Kusiyara River FloodPlain”. The upazila comprises of 7 unions and one pouroshobha having a population of 2,58,266(2001). Five land types namely high land, medium high land, medium low land, low land and very low land were identified. The textural classes of soil found were loam, clay loam and clay. Eleven soil groups were identified. Eight major cropping patterns were found in the upazila. Total 120 soil samples were collected and analyzed and found that the soils of the upazila are deficient in major nutrient elements along with micro- nutrient element Zn and B. Karimgonj upazila was first surveyed in 1991 and updated in 2008.

Location: Karimgonj, Kishoregonj

Start Date: 01-11-2008

End Date: 31-10-2009

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Soil and land resources inventory of Karimgonj 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:

Karimgonj upazila is situated in the mid northern part of Kishoregonj district. It lies under the AEZ 9 (Old Brahmaputra Flood Plain) and AEZ 21(Sylhet Basin). In this upazila major land type recognized was highland comprising 31.1% of total area followed by medium highland comprising 23.2% of the total area. Major textural class also identified were clay(32.9%) and loam(32.1%) followed by clay loam 18.6%. Eleven soil groups were identified namely Sonatola, Silmondi, Lokdeo, Ghatail and Balina in Old Brahmaputra Floodplain and Balagonj, Guainghat, Kanairghat, Fagu, Sulla, Therchibari in Surma-Kusiyara Floodplain of the upazila. Sonatola soils cover the major part (27.5%) of the upazila.

According to local agro-ecology suitable crops identified were Jute(Deshi, Tosha), Boro(Adhunik), Aus(Adhunik), T.Aman(Adhunik, Local), Sugarcane, Deep Water Aman, Wheat, Maize(robi and kharip), Groundnut(robi and kharip), Mustard, Robi Soybean, Chilli, Cauliflower, Cabbage, Brinjal, Lentil, Gram, Mango, Jackfruit and Coconut. Eight major cropping pattern namely Whole the year round crop(Sugarcane), Robi Vegetable-Kharip Vegetables, Boro-Fallow-T.Aman, Fallow-Jute-T.Aman, Robi crops-Fallow-T.Aman, Robi Crops-Jute-T.Aman, Boro-Jute-T.Aman, Boro-Fallow-Fallow were identified among which Boro-Fallow-T.Aman covers the major part (35.5%). Fertilizer recommendation for suitable crops is given in the guide.The guide can be used for determining flood and drought, landslide, 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.
