The present investigation was carried out to study the available nutrient status and to prepare soil fertility maps which are important for nutrient management for higher and sustainable crop production. Five hundred two (502) numbers of soil samples were collected from different villages of all the eight blocks of Nayagarh District by using Global Positioning System (GPS) followed by analysis of physico-chemical properties and maps were prepared subsequently. The results revealed that the soils under investigation were acidic in reaction (pH 5.74 to 6.49), low in EC (0.08 to 0.14 dS m-1) and organic carbon status (5.5 to 6.8 g kg-1). The mean values of available nitrogen content varied from 124.8 to 186.2 kg ha-1, available P from 6.3 to 13.78 kg ha-1 and potassium status from 223.0 to297.7 kg ha-1. Thus, soils were found to be deficient in available N and P and medium in potassium status in Nayagarh district. The soil status of mean available Sulphur was high (14.98 to 24.22 mg kg-1) except in Daspalla block. Hot water soluble boron content was above the critical limit (0.42 to 0.60 mg kg-1) in most of the soils of Nayagarh district. Mostly four types of texture classes were observed in the district namely loamy sand, sandy loam, clay loam and sandy clay loam. Clay content was found to be positively correlated with all the parameters. Significantly positive correlation among different parameters was found except sand which showed negative correlation with all the parameters.
