Abstract:

P adsorption maximum was significantly and positively correlated with pH (r = 0.85**), clay (r = 0.96**) and silt + clay (r = 0.94**), however, the binding energy showed a significant and positive correlationship with organic carbon (r = 0.68*) only. In case of Freundlich Isotherm there was no significant relationship between Freundlich adsorption parameters and soil properties except between the empirical constant ‘K’ and soil pH. Clay content dominated the P adsorption of these soils as indicated by its significant regression coefficient. Soil pH, organic carbon, clay, clay + silt, available P and total P together accounted for 98% of Langmuir ‘b’, 52% of Langmuir ‘K’, and 78%of Freundlich ‘n’ and 56% of Freundlich ‘K’ respectively. The values of buffering capacity for Vertisol, Alfisol and Inceptisol were 1.90, 0.86 and 0.22 and the P sorption at 0.2 ppm solution concentration was found to be 61.40, 49.27 and 30.19 for Vertisol, Alfisol and Inceptisol respectively.
