All the soils under study was 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 Shivani block contain 137.98 to 200.70 kg ha^-1 available nitrogen, 14.78 to 19.35 kg ha^-1 available Phosphorous and 276 to 337 kg ha^-1 available potassium. The soils of Shivani block contain available micronutrients i.e. Zn, Cu, Fe, Mn in the range of contains 0.44 to 0.98 mg kg^-1 0.44 to 3.20 mg kg^-1 3.2 to 8.2 mg kg^-1 2.0 to 6.4 mg kg^-1. Zn, Cu, Fe, Mn respectively.

The nutrient index value calculated for soils of Shivani block shows that this soil has moderate NIV for organic carbon, low NIV for available nitrogen and Shivani block whereas phosphorous show moderate NIV for Shivani block, high NIV for available potassium. The micronutrients status show high NIV for iron, copper and manganese, The Shivani block shows moderate to moderately high NIV for zinc.

It is revealed that in the soils of Shivani 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.
