Soil Samples are collected for Phosphorus Adsorption behavior from three representative soils of Chhattisgarh which belong to the Inceptisol, Alfisol and Vertisol. Two adsorption equation viz., Langmuir and Freundlich were used to describe P adsorption behavior. The P adsorption at the solid phase was strongly related to its concentration in the solution phase and Vertisol with maximum clay content recorded highest P adsorption at a given equilibrium P concentration indicating that P ions are most tightly held by Vertisol. The identical and high values of R2 both for Langmuir and Freundlich Adsorption Isotherms indicated that the P adsorption data conformed to both isotherms indicating their goodness of fit. The P adsorption maxima ‘b’ was highest for Vertisol followed by Alfisol and Incptisol. The value of Langmuir ‘K’ showed an increasing trend in the same order indicating a high affinity of Vertisol for P, which had resulted in higher value of ‘b’. The value of Freundlich ‘n’ showed a slight increasing trend in the order Vertisol > Alfisol > Inceptisol, whereas, its ‘K’ value showed a decreasing trend in the same order.
