Abstract


Eight soil series differing in soil characteristics were analysed for discrete soil P fractions and their relationships established. Saloid P constituted only 0.5 to 0.6 per cent of the total P content of the Alfisols and Entisols. Clay content negatively correlated with saloid-P (-0.661**). There was a highly significant and positive correlation between saloid-P and Bray 1-P (r=0.926**). Al-P constituted 5.2 to 15.6 per cent of the total P and Fe-P contributed 7.8 to 21.0 per cent of the total P. Ca-P constituted the highest fraction occupying 23.6 to 53.3 per cent of the total P.
