  • 摘要:Phosphate sorption data of four soil samples representing two soil series (Sedu and Jawa 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 represents 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 r2 values of 0.98 and 0.99, respectively, while, Serkat and Kuala Linggi soils have r2 valuesof 0.96 and 0.95, respectively. Phosphate adsorption maxima and buffercapacities 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 ha1 reduced phosphate sorbed by 3.1 and 13.1 percent, respectively. Rates greater than 2 t ha1 of lime increased the P sorptive capacities of the soils
