Abstract: The present study was undertaken to assess the vertical distribution of macronutrients viz., nitrogen (N), phosphorus (P), potassium (K) and sulphur (S) in relation to soil properties in five selected soil profiles, one each from Suri II (P1), Rampurhat II (P2), Md Bazar (P3), Nalhati I (P4) and Sainthia (P5) block of Birbhum district of West Bengal. These five soil profiles were collected from the paddy growing areas of Birbhum district. The soil texture varied from silt loam to silt. Based on the fertility ratings, pH of soils was strongly acidic to neutral in nature. Its value ranged from 5.01-7.07. Electrical conductivity (EC) value ranged from 0.06-0.12 dS/m. Its values were in safe limits (<0.1 dS/m) in the study area. The Organic carbon content was more in surface horizons than in sub-surface horizons. pH and EC followed increasing trend with decrease in depth along the profiles. The available macronutrients varied from 75.26-275.97 kg/ha for available N, 8.65-25.22 kg/ha for available P, 137.55-310.32 kg/ha for available K and 1.03-3.01 mg/kg for available S. The available macronutrients decreased with increasing depth in all the profiles. The available N and P were low to medium and S was low in status. High to medium K content was found at surface layer in all five soil profiles whereas at lower depth its value was found to be low to medium. Macronutrients showed decreasing trend with increase in depth. pH showed significant and negative correlation with all the macronutrients, whereas organic carbon showed significant and positive correlation.
