Determining the effects of soil conditioners on water erosion in soils with different textures by using rainfall simulator.

The water erosion, which can be observed in every region where high intensity precipitation and sloping lands are present, is a type of erosion that erodes the soils at most. In this study, simulated rainfalls having the intensity of 100 (± 3) mm.h-1 were applied for one hour on three different eroded soil samples (Clay loam, Sandy loam and Loam) through three different methods involving Control, PAM (7.5 kg.ha-1) and PG (7.5 ton.ha-1) in three repetitions. While PAM applications increased final infiltration values at the rate of 70% and total infiltration values at the rate of 39-48%, they decreased runoff values at the rate of 19-41%, runoff erosion at the rate of 200-300% and amount of soil replaced with side splash at the rate of 250-300%. PG applications increased final infiltration values at the rate of 54-57% and total infiltration values at the rate of 28-38% whereas they decreased runoff values at the rate of 20%, runoff erosion at the rate of 190-260% and amount of soil replaced with side splash at the rate of 200-260%. PAM applications enhanced more positive effect of 0-50% for all erosion processes. According to results of analysis of variance, positive effects of PAM and PG on erosion processes were found to be significant at P<0.05 and P
