Preparation of Upazila Land and Soil Resource Guide, Kishorganj Sadar Upazila

Abstract/ Executive Summary:

Kishorganj upazila is situated in north-western part of Kishorganj district lying between 24º21´-24º32´ north latitude and 90º43´-90º53´ east longitude covering 17,871 ha area. It lies in the physiography of Old Brahmaputra Floodplain (AEZ 9). The upazila comprises of 11 unions and a pourosava having a population of 384,382 (2001). Land types recognized were highland (8.7%), medium highland (39.6%), medium lowland (13.8%), lowland (10.10%) and very lowland (0.60%). Textural classes identified loam (17.4%), clay loam (27.5%) and clay (27.9%). Major soil groups identified were Ghatail, Silmandi, Lokdeo and Sonatala. Soils of this Upazila are deficient in N, P and S. A total of 86 composite soil samples were collected and analyzed. Kishoreganj upazila was first surveyed in 1990 and updated in 2009. Fertilizer recommendations for existing and potential crops at high and medium yield goals are given. Eleven major cropping patterns were found. Addition to location specific fertilizer recommendation this guide can be used for determining crop suitability, site selection of demonstration or trials, determining management area and plan against flood, drought, water-logging and soil erosion.

Keywords: Kishorganj sadar, Land type, Soil group, Cropping pattern,Guide

Location: Kishorganj Sadar Upazila

Start Date: 01-01-2007

End Date: 30-05-2009

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Kishorganj Sadar 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. Crops, cropping patterns, inundation land types, 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: 110,000

Total Budget (Tk.) : 110,000

Achievement/Findings:

In this upazila, some of the suitable crops identified were jute (deshi/tosa), T. Aus rice (HYV), B. Aus rice, T. Aman (HYV, LIV), sugarcane, deep-water Aman, wheat, maize (rabi and kharif), groundnut (rabi and kharif), mustard, rabi soyabin, rabi chilli, cauliflower, cabbage, rabi eggplant, lentil, gram, mango, jackfruit. Major cropping patterns were Boro rice (HYV)-Fallow(F)-F; Boro (HYV) rice-F-T.Aman; F-T.Aus-T.Aman: F-F-T.Aman. Upazila Guide as a micro-level agricultural planning tool delineates existing soil/land and water resource data bases. It helps plan research activities, set location specific crop trials and demonstration and determine site specific suitable crops and cropping patterns, development of surface and subsurface irrigation network, soil and water conservation measures and drainage system improvement. Use of the guide as a vehicle for agro-technology transfer and diffusion will enable the farmers to apply balanced fertilizer applications, use appropriate soil management technologies and thus increase crop production. The guide can also be used as a data base for other local level development plans such as development of community forestry, fisheries and livestock, re-excavation of canals and construction of embankment, roads, culverts and bridges.
