Abstract: Evaluation of the soil fertility status of Inceptisol group of Balodabazar block of Balodabazar district of Chhattisgarh was carried out during 2016-17. Grid based surface (0-15 cm) soil samples were collected by systematic survey from 55 villages in Balodabazar block in such that each 10 ha area represented one sampling point and total 566 soil samples covering all soil types out of this, 566 samples were identified from Inceptisol. These samples were analyzed for pH, EC, organic C and DTPA-extractable Zn, Cu, Fe, Mn. The pH varied from 5.0 to 7.9 with the mean value 6.4, EC ranged from 0.10 to 0.70 with the mean value 0.25 dS m-1. The variation in organic C content in soil samples was ranged from 0.30to 0.75 with the mean value 0.59 %. DTPA-extractable Fe, Mn, Cu and Zn status were recorded as 2.30 to 41.98 (19.24 mg kg -1), 3.08 to 45.70 (22.59 mg kg-1), 0.42 to 3.06 (1.79 mg kg-1) and 0.20 to 2.90 (0.81 mg kg-1), respectively. Soil pH showed significant and positive correlations with DTPA-extractable Zn and showed negative significant Mn and Fe. EC indicated significant and positive correlated with pH (r=0.199) and positive nonsignificant OC (r=0.057). Soil organic C showed positive and significant correlation with DTPA-extractable Mn and Zn.
