All the soils under study were slightly alkaline to moderately alkaline in reaction, EC value for these soils within safe limit. The organic carbon content in these soils is low to medium and soil of farms is moderately calcareous to calcareous due to presence of CaCO₃.

The soils of Babhulgao block contain 146.76 to 213.25 kg ha^-1 available nitrogen, 14.52 to 18.82 kg ha^-1 available phosphorus and 247.8 to 341.6 kg ha^-1 available potassium. The soils of babhulgao block contain available micronutrients i.e. Zn, Cu, Fe, Mn in the range of contains 0.33 to 0.69 mg kg^-1, 0.28 to 3.28 mg kg^-1 2.32 to 7.80 mg kg^-1, 1.50 8.60 mg kg^-1 respectively, Zn, Cu, Fe, Mn respectively.

The nutrient index value calculated for soils of Babhulgao block shows that soils has moderate NIV for organic carbon, low NIV for available nitrogen and moderate for phosphorus, high NIV for available potassium. The micronutrients status show high NIV for iron, copper and manganese, The Babhulgao block shows the low NIV for zinc.

It is revealed that in the soils of Babhulgao block, the availability of nitrogen, iron, zinc decreases with increase in CaCO₃ content. Available copper also decreases with increase in soil pH. The availability of zinc decrease due to increase in EC. The availability of manganese, copper, increase with increase in organic carbon status in course of investigation.
