Precise nutrient management is one of the most essential and vital aspects of modern agricultural practices. To make this happen, we must know about the spatial variability of soil fertility. A detailed geo-referenced investigation was conducted to study the plant’s available nutrient status and prepare soil fertility maps, which would act as an important tool for soil as well as nutrient management for higher and more sustainable crop production. The soils of different Villages in each block of Jharsuguda district were collected using GPS instruments and analyzed for chemical properties and maps were prepared subsequently. The results revealed that the soils under investigation were acidic in reaction (pH 5.29 to 5.58) and low to medium in organic carbon status (0.47 to 0.85 %). The mean available nitrogen content varied from 214.09 to 381. 95 kg ha^-1, available P content from 15.32 to 25.62 kg ha^-1 and potassium status from 314.45 to 378.42 kg ha^-1. Thus, on a mean basis, the soils of the Jharsuguda district of Odisha were medium in available N and P and high in K status. On the contrary, the mean available sulfur content was found deficient (5.00 to 17.14 kg ha^-1). Hot water-soluble boron content was below the critical limit (0.27 to 0.44 mg kg^-1) in most of the soils of Jharsuguda district.
