This study was conducted to evaluate micronutrients status of Malkharauda block in Janjgir-Champa district of Chhattisgarh covering 110 villages during 2011–2012. The systematic collection of samples in geo–referenced surface (0-15cm) soils samples from 2640 sites representing Inceptisols, Alfisols and Vertisols using Global Positioning System and mapped on 1:4000 Scale. The samples were analyzed for DTPA-extractable zinc, copper, iron and manganese content for delineation of the fertility status in relation to salient physico-chemical characteristics. the study revealed that the DTPA-extractable copper content ranged from 0.2 to 11.1 mg kg⁻¹. The available Mn, Fe and Zn content ranged from 3.9 to 66.0, 3.2 to 66.0 and 0.1 to 6.2 mg kg⁻¹, respectively. These results indicated that zinc is likely to be constraint for crop production in soils of Malkharauda block.
