The purpose of this study was to investigate the effects of different levels (0, 0.5, 1, 1.5 and 2 g/kg of soil) of superabsorbent polymers A, perlite and zeolite on the physical properties of sandy loam soil in factorial randomized complete block design with four replications. Soil moistures were determined at seven suction points from 10 to 1500 kPa. The results of this study showed that the 2g super adsorbent polymer per kg of soil increased soil porosity, mean weight diameter of aggregates and available water for plant up to 2.6, 2.71 and 1.40 times, and reduced the bulk density of the soil up to 0.82 times, as compared to the control. Also, the results showed that in all suction points, the soil moisture content increased significantly as compared to the control.
