Abstract: The present investigation was carried out to study assessment of different nitrogen forms in soils of Tuljapur Tehsil of Osmanabad district. For this purpose 180 representative soil samples were collected from 30 villages of Tuljapur Tehsil. The collected soil samples were grouped into three orders viz. Vertisols, Inceptisols and Entisols. Out of the total surveyed soil samples, 34 per cent samples were grouped under Vertisols while, 47 per cent and 19 per cent samples were grouped under Inceptisols and Entisols, respectively and orderwise analysis was carried out. In chemical analysis, the soils under study area were alkaline in reaction, safe in limit of electrical conductivity and moderately calcareous to calcareous in nature. The organic carbon content in soils was found low to medium. In chemical analysis, the soils under study area were alkaline in reaction, safe in limit of electrical conductivity and moderately calcareous to calcareous in nature. The organic carbon content in soils was found low to medium. The soils were found to be low in all the fractions of N viz. total N, available N, total hydrolysable N, amino acid N, acid insoluble N, ammonical N and nitrate N in all three orders viz. Vertisols, Inceptisols and Entisols.
