| Several methods have been introduced to control soil erosion. One of the newest methods used to control soil erosion and reduce runoff is the use of polymers.This study was conducted to determine the effects of different rate of Polyacrylamide, PAM, (0, 0.2, 0.4, and 0.6 gm2) on marl soils in rainfall different durations (10, 20 and 30 minute) using FEL3 rainfall simulator with rain high intensity 120 mm/hr at Laboratory. The results showed that all of the PAM levels (0, 0.2, 0.4 and 0.6 gm2) in the three rainfall durations (10, 20 and 30 minute) had significant differences in decreasing splash erosion in comparison with control treatment. However, the interaction effect of rain duration and PAM levels, were not statistically significant. Low rate of PAM (0.2 gm2) cannot control splash erosion as well as, however decreased it less. The statistical analyzes showed there was no statistical significance noted at a rain duration of 10 min, however at rain duration 20 and 30 min, with different amounts of PAM, there was a significant difference in splash erosion control. When rain duration increased from 10 to 30 minute, the splash erosion enlarged. So, the splash erosion decreased due enhancement of PAM level, as the most effect was observed in rain duration 30 min and 0.6 gm2 PAM rate respect to control treatment which is 21.2% effective in decreasing erosion. This reduction was statistically significant at 95% level with Duncan test. | ||
