A Study was undertaken to evaluate the fertility status of Jaijaipur block in Janjgir- Champa district, Chhattisgarh covering 105 villages during 2011-2012. The systematic collection of samples in geo–referenced surface (0-0.15m) soils samples from 1507 sites representing Inceptisols. using Global Positioning System. The samples were analyze for DTPA-extractable zinc, copper, iron, manganese content for delineation of the fertility status in relation to salient physico-chemical characteristics. The statistical description of soil characteristics indicated that the pH of the soils varied from 4.3 to 6.9. The electrical conductivity of soil-water suspension ranged from 0.06 to 0.38 dS m-1. The organic carbon content in these soils varied from 0.22 to 0.68%. The DTPA-extractable copper content ranged from 0.04 to 10.80 mg kg-1. The available Mn, Fe and Zn content ranged from 2.9 to 57, 4.3 to 64.8 and 0.1 to 1.98 mg kg-1, respectively. These results indicated that zinc is likely to be constraint for crop production in soils of Jaijaipur block. A positive significant correlation was found between pH and EC in Inceptisols, pH had negative and significant correlation ship with available Fe in Inceptisols Further, the correlation ship between OC and available micronutrient was found negative & significant with Mn & Fe in Inceptisols. The soils are moderately acidic to neutral in reaction, low to medium in organic carbon, The available copper, manganese and iron content showed high level, whereas about 90% area under soils delineated as sufficient in available zinc content.
