Soil Resource Development Institute, District Office, Sylhet.

Abstract/ Executive Summary:

Moulvibazar upazila lies between 24° 24'and 24° 38' north latitude and 91° 37' and 91° 50' east longitude and covers an area of 34,419 ha. It lies in the physiographic unit of Northern and Eastern Hills, Northern and Eastern Piedmont Plains and Surma - Kusiyara Floodplain. The upazila comprises of 1 Pouroshova and 12 unions having a population of 2,81,593 (2001). Five land types namely highland, medium highland, mediam lowland, lowland and very lowland were identified. The textural classes of soil found were sandy loam, loam, clay loam clay. Ten soil groups were identified. Thirteen major cropping patterns were recorded in the upazila. Total 184 soil samples were collected and analyzed and found that the soils of the upazila are deficient in almost all essential nutrient elements except B, Cu, Fe and Mn. The upazila comprises of highland, medium highland, medium lowland, lowland and very lowland so the area is suitable for both upland and wetland crops. The climate, land form and geo-morphological environment of the area are suitable for tea, lemon, orange, pummelo, pineapple, zinger, turmeric, vegetables and rice cultivation. Moulvibazar upazila was first surveyed in 1995 and updated in 2013.

Program Area: Resource Development and Management

Commodity: Land management

Objectives:

1. Soil and land resources inventory of Moulvibazar 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:

Moulvibazar Sadar upazila is situated in the north-west part of Moulvibazar district. It lies under the AEZ no. 29 (Northern and Eastern Hills), AEZ no.22 (Northern and Eastern Piedmont Plains) and AEZ no.20 (Surma - Kusiyara Floodplain).In this upazila major land type recognized was highland comprising 11.4 % , medium highland comprising 43.5 %, medium lowland 17.8 % ,lowland 7.5 % and very lowland comprising 2.3% of the total area. Major textural class also identified was clay loam covering 55.5% , loam 20.6 %, clay 2.3 % and sandy loam 4.1% of total area. Ten soil groups were identified namely Baralekha, Sreemangal, Bijipur, Pritimpasa, Manu, Balagonj, Goyainghat, Kusiyara Phagu, Terchabari. In Northern and Eastern hill area of highland Baralekha covers major area (3.4%) ,in Northern and Eastern Piedmont Plains of medium highland Pritimpasa covers major area (2.8%), In Surma-Kusiyara Floodplain area Goyainghat soil group in medium highland covers the major area (24.7%), in medium lowland and lowland Phagu covers the major area (11.0% and 7.5% respectively),in very lowland Terchabari covers the major area (2.3%). According to local agro-ecology suitable crops identified were tea, lemon, orange, pineapple, zinger, turmeric, vegetables, rice etc. The area is most suitable for wetland crops and also for tea.Fourteen major cropping pattern namely tea, forest (Koroi, Garjan,Teak,Gamari,Rubber and others), Horticulture Crops (Pineapple/lemon/Guava/Papaya etc.), robi vegetables (Tomato/Potato/ Bitter gourd /Sweet gourd/Brinjal)- kharip vegetables(Indian spinach/Okra/ String Beans), robi vegetables (Tomato/Potato/ Bitter gourd /Sweet gourd/Brinjal)-fallow-T.aman, Fallow-B.aus-T.aman, Fallow-fallow-T.aman, Fallow-T.aman-B.aman, Boro-fallow-B.aman, Fallow-fallow-B.aman, Boro-fallow-fallow, Bush and fallow were identified.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 whether the Upazila is food deficit or surplus area.
