This study was conducted to evaluate the effect of the mixed ratio of zeolite and perlite as soil amendment on the soil physicochemical properties applied to golf course green. The soil amendments were 0, 3, 5, 7 and 10% by soil volume. Soil chemical factors such as pH, electrical conductivity (EC) and cation exchangeable capacity (CEC) were increased by higher proportion of zeolite amount, while not significantly different perlite addition. Soil physical factors like capillary porosity, air-filled porosity and total porosity were increased perlite proportion, while not significantly different in zeolite treatments. For correlation coefficients between percentage of soil amendments and soil physicochemical factor, zeolite was positively correlated with CEC (p<0.01), and perlite showed positive correlation with porosity and hydraulic conductivity (p<0.01). These results indicate that zeolite improved cation exchangeable capacity, and perlite was found to modify a water permeability and root zone aero-environment.
