Rangpur dtrict consists of eight upazilas. Five of these upazilas were selected, i. e. Rangpur sadar, Mithapukur. Pirganj, Badarganj, and Taraganj on the basis of intensity of maize cultivation. In Rangpur sadar upazila three villages, i.e., north Binodpur (R I, R2), south Binodpur (R3, R4) and Dharmadas (R5, R6) were selected under Darsana and Tampat union. In Badarganj upazila, three villages, i.e., Sontospur (R7,R8), Mainarpara (R9, RIO), and Munshipara (Rll, Rl2) under Madhapur union. In Pirgacha uapazila, Deuti (R 13, Rl4) and Gulal (Rl5, R16) villages under Parul umon. In Mithapukur upazila, Koddomuradpur (Rl7, Rl8) and Kesobpur (Rl29,R20) villages under Pairabandth union. In Taraganj upazila Pataipara (R21, R22) village under Hariakuti union. Soil samples were collected from two depths, viz, surface (0-15 em) and subsurface (> 15- 30 cm) at each locations. Each sample was a composite sample of five sub-samples. Samples were collected by augar boring method. Notations for surface (0-15 cm) and subsurface soils (> 15-25 cm) were (Rl, R3, R5, R7, R9, Rll, Rl3, RJ5, Rl7, Rl9, and R21) and ( R2, R4, R6, R8, RIO, Rl2, Rl4, RJ6, RJ8, R20 and R22), respectively. Moisture contents of the soil samples at field condition were determined by gravimetric method (Klute, 1986). Hydrometer method (Bouyoucos, 1962) was used for determining the percentage of sand, silt and clay and the textural class of the soil was determined by "Textural triangular coordinates". Bulk density of the soil was determined by core method at field condition. Soil pH was measured electrometrically using a Corning Glass Electrode pH meter (Model-7) at a soil: water ratio of I: 2.5 (Jackson, 1967). Organic carbon content of the soil was determined volumetrically following Walkley and Black's Wet Oxidation method (1934). Organic matter content of the soil was then calculated by multiplying the percentage of organic carbon with "Van Bemmelen Factor" of 1 .724. Total nitrogen content of the soil was determined by Micro-Kjeldhal's method following sulphuric acid digestion and steam distillation. Total phosphorus (P) content of the soil was determined by Spectrophotometer following (HN03: HCJ04) acid digestion. Available P was also determined by Spectrophotmeter by extracting the soil with ammonium fluoride and HCI solution. Total potassium (K) content of the soil was determined Flame Photometrically by Gallenkamp Flame Analyser following (HN03: HCI04) acid digestion. Available K was also determined by Flame analyzer by extracting the soil with ammonium acetate solution (pH= 7.0).
