Abstract/ Executive Summary:

Kalai is situated in about middle part of Joypurhat district. It lies between 24º58´ and 25º11´ north latitude and 89º08´ and 89º17´ east longitude and covers an area of 1,636 ha. It lies in the physiography of Barind Tract. The upazila comprises of 5 unions having a population of 129,329 (2001). Land types recognized were highland (33.4%), medium highland (47.4%) and medium lowland (0.8%). Textural classes identified loam (48.2%), clay loam (33.3%) and clay (0.4%). Soil groups identified Amnura (63%), Akdala (9.6%), Kahalu (0.4%). Total 74 soil samples were collected and analyzed. Soils of this Upazila are deficient in N, P, K, Ca, Mg and organic matter. Seven major cropping patterns were found. Fertilizer recommendations for suitable crops are given. Fertilizer recommendations for 40 existing and potential crops of the upazila at high and medium yield goals for 89 crops at high yield goal are given. This guide can be used for determining flood, drought, water-logging, and soil erosion. Kalai upazila was first surveyed in 1997 and updated in 2010.

Keywords: Barind Tract, Kalai upazila, Soils, Cropping patterns,Guide

Location: Kalai Upazila, Joypurhat

Start Date: 01-01-2008

End Date: 30-06-2010

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Kalai 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: 120,000

Total Budget (Tk.) : 120,000

Achievement/Findings:

In this upazila, suitable crops identified were rice (Boro, T. Aman, deep-water Aus and Aman), potato, wheat, millet, rabi maize, rabi cotton, mustard, rabi soybean, cabbage, jute (Deshi/Tosa), chilli, sugarcane, zinger, turmeric, mango, jackfruit, kul, banana. Major cropping patterns were Potato/Mustard-Boro rice-T.Aman (50.8%); Boro rice-Fallow-T.Aman (14.5%); Rabi crops (Wheat/Maize)-T.Aus-T.Aman (11.8%). 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.
