In present study, phosphorus fractions in representative agricultural soils belonging to three soil orders Vertisol, Inceptisol and Alfisol JNKVV, Farm, Jabalpur were investigated. Result revealed that the highest soil pH analysed in Vertisols with the range 7.57 to 7.68 followed by Alfisols range 6.37 to7.18 and low pH found in Inceptisols, which 6.27 to 6.72 soil orders, respectively. The EC was existed as normal in all the orders < 1 dS m-1 at 25°C. The organic carbon content was recorded in different soil orders ranged from 4.60 to 6.60 g kg-1. The CaCO3 content was found to be ranged from 40 to70 g kg-1. Overall, the soils are non-calcareous in nature. Vertisols have the highest CEC value fallowed by Inceptisols and Alfisols, which have minimum CEC value. The available N content in soils varied from 239.14 to 302.70 kg ha-1 in different soil orders. The available phosphorus content in three soils orders varied from 11.24 to 30.79 kg ha-1. The available K ranged from 308.32 to 345.60 kg ha-1 in Vertisols, 289.76 to 336.08 kg ha-1 in Inceptisols and it was ranged from 276.96 to 322.80 kg ha-1 in Alfisols. The available N, P and K were low to medium in different soil orders. Vertisols and Inceptisols were found to be in order of Ca-P>Al-P>Occluded-P> Fe-P>Saloid-P. Whereas, Alfisols in order of Ca-P>Fe-P>Al-P>Occluded-P>Saloid-P. The Ca-P was found high in the Vertisols. But Fe-P and Al-P were recorded maximum under Alfisols.
