R.1200611This study was carried out to investigate whether relationships could be established among total P, extractable P and soil solution P under fertilized and unfertilized conditions for unburned pineapple residue management practices in pineapple cultivation on tropical peat soils. Results showed that the relationship among total P, extractable P and soil solution P for the fertilized condition was quadratic at 0-10 cm depth. There was no significant relationship at the same depth for the unfertilized condition. There was no relationship among the three forms of P for both of the fertilized and unfertilized conditions at 10-25 cm and 25-45 cm depths. This observation was attributed to low bulk density and leaching of P. Only top soil under fertilized condition affects the nature of the relationship among total, exchangeableand soil solution P in pineapple cultivation tropical peat soils.]]>Ahmed, O.H., M.H.A.
