 ABSTRACT

Forty-six soil samples from nine different soil series of Bhiwapur tahsil of Nagpur district of Maharashtra state were selected for randomly to study the available macro as well as micronutrient status of the soil. The physico-chemical properties like pH, electrical conductivity (EC), organic carbon (OC) and free CaCO3 content of the soils varied from 7.1 to 8.2, 0.10 to 0.36 dS m-1, 3.45 to7.75 g kg-1 and 1.58 to 10.75 per cent with the mean value of 7.65, 0.19 dSm-1, 5.75 g kg-1 and 4.91 per cent, respectively. Most of the soils were found low in nitrogen (N) and phosphorus (P) and high in potassium (K). Available N status of these soils was in the range of 132 to 278 kg ha-1 (mean value of 198 kg ha-1), available P varied from 5.14 to 24.56 kg P2O5 ha-1 (mean value of 12.56 kg P2O5 ha-1) and 94% of the soil samples showed high available K content. The available S content was in the range of 5.23 to 23.15 kg ha-1 (mean value of 11.15 kg ha-1). The soils were sufficient in available Mn and Cu, whereas, deficient in Fe and Zn. Soil DTPA-extractable micronutrients, Zn, Cu, Mn and Fe ranged from 0.29 to 1.44, 1.11 to 3.26, 6.62 to 17.44 and 4.10 to 10.17 mg kg-1 (mean value of 0.52, 1.89, 11.25 and 5.76 mg kg-1), respectively. Soil pH of the surface layer had a significant and negative correlation with available S and Cu (r=-0.395** and -0.289**). Soil OC showed a significant positive relationship with available N, Mn and Cu (r=o.539**, 0.398** and 0.562**). The free CaCO3 was significantly and negatively correlated with available N, S, Fe, Mn and Zn (r= -0.437**, 0.314**, -0.372**, -0.437** and -0.268**), respectively. The investigation provides preliminary information on fertility status of different soil series of Nagpur district (Maharashtra), which shall help in the formulation of nutrient management schedule in future for the better productivity of different crops.
