Although soil fertility mapping can help to apply appropriate fertilisers and effective fertility management techniques, there is still little information about spatial variability in fertility status of soil. Therefore this study was conducted at Hingoli and Sengaon tahsils with objects of assessing fertility status. From the study area 200 soil samples were collected and analysed in laboratory for micro nutrients. In micro nutrients Zinc indicate deficient condition followed by Fe, Cu and Mn may be due to frequent cultivation, variations in management practices, high use of chemical fertilisers. DTPA- Zn content in soils of Hingoli tahsil were ranged from 0.14 to 1.75 mg kg-1 with a mean value of 0.57 mg kg-1, DTPA- Fe content were ranged from 1.00 to 18.80 mg kg-1 with an average value of 5.92 mg kg-1, DTPA-Mn content varied from 0.88 to 19.70 mg kg-1 with a mean value of 6.58 mg kg-1. The available DTPA-Cu contents of Hingoli soils were ranged from 0.27 to 5.50 mg kg-1 with an average value of 1.73 mg kg-1. The data revealed from Sengaon tahsil that the available Zn content of these soils was ranged from 0.15 to 1.28 mg kg-1 with a mean value of 0.49 mg kg-1. The available Fe content of these soils was varied from 0.96 to 12.85 mg kg-1 with an average value of 5.90 mg kg-1. The available Cu content in the soils of Sengaon tahsil were ranged from 0.12 to 3.86 mg kg-1 with a mean value of 1.17 mg kg-1. The lowest range 1.70 to 5.75 mg kg-1 Mn with a mean value of 4.06 mg kg-1 were observed in Makodi whereas highest range 6.87 to 14.00 mg kg-1 with an average value of 9.72 mg kg-1 Mn was recorded in village Wadhivra village. Therefore for increasing fertility of soil create public awareness about environmentally and socially acceptable integrated nutrient management practices like use of organic inputs, balanced use of chemical fertilisers, agro-forestry system and improved crop varieties can be adopted. Thus, it can be concluded that soils of Hingoli and Sengaon tahsil are low to medium in fertility status.
