Polyacrylamide (PAM) was applied on three different textured soils with textures of clay loam, loam and loamy sand. Next to sample preparation, 10, 20 and 30 kg/ha of PAM were added to soil surfaces. Samples were exposed to rains produced by mini rainfall simulator with an intensity of 39 mm/h. The resulted runoff and sediment was collected and measured. The same procedure was conducted for a rainfall with an intensity of 79 mm/h. The results revealed that all levels of PAM decreased the amounts of runoff and sediment significantly as compared to control. At 39mm/h intensity, loam and loamy sand soils release the least amount of sediment when treated with 10 kg/ha of PAM. Clay loam soil had the minimum amount of sediment in treatment of 20 kg/ha of PAM. At 79mm/h intensity, all soil samples with 30kg/ha of PAM produced the minimum amounts of sediment. All soils at 39 and 79mm/h rain intensity showed the minimum runoff in 10kg/ha of PAM treatment. The loamy sand soil did not produce any runoff at 39mm/h rain intensity in any level of PAM treatment.
