Phosphate sorption by active acid sulfate soils of Peninsular Malaysia
Phosphate sorption data of four soil samples representing two soil series (Sedu and lawa Series; both Typic Sulfaquepts) from Peninsular Malaysia were described by the Langmuir II sorption model. Lim Chin, Raja Muda and Kuala Linggi soils represent Sedu series, while the soil sample from Serkat re...

| description | Phosphate sorption data of four soil samples representing two soil series (Sedu and lawa Series; both Typic
Sulfaquepts) from Peninsular Malaysia were described by the Langmuir II sorption model. Lim Chin, Raja Muda
and Kuala Linggi soils represent Sedu series, while the soil sample from Serkat represent Jawa Series. The phosphate
sorbed by the four soil samples conformed to the Langmuir II adsorption isotherm. Lim Chin and Raja Muda
estate soils have r values of 0.98 and 0.99, respectively, while Serkat and Kuala Linggi soils have r values
of 0.96 and 0.95, respectively. Phosphate adsorption maxima and buffer capacities were higher in the Sedu soils
(Lim Chin and Raja Muda Estate) than in Jawa (Serkat) and the Sedu soil (Kuala Linggi). Liming of the Sedu
Soil (Raja Muda Estate) and Jawa soil (Serkat) at 1 t ha- I reduced phosphate sorbed by 3.1 and 13.1 percent,
respectively. Rates greater than 2 t ha-J of lime increased the P sorptive capacities of the soils. |
