Department of Soils and Agricultural Chemistry, Orissa University of Agriculture and Technology, Bhubaneswar, Orissa, 751003.
The amount of P fixed at four different levels of added P (25, 50, 100 and 150 ppm)and maximum P fixation capacity of some Alfisols of Orissa showed highly significant positive correlations with c1ay, free oxides, total exch, cations and negative correlation with the available P content. The soil factors contributed to 80 to 83 per cent of the variations in the amounts of P fixed at various levels of added P and also of the maximum P fixation capacity. The soil factors along with the concentration of added P accounted for 87 per cent of the amount of P fixed at different levels of P added to soil.
