DETERMINING THE EFFECTS OF SOIL CONDITIONERS ON WATER EROSION IN SOILS WITH DIFFERENT TEXTURES BY USING RAINFALL SIMULATOR

WOS: 000444528000006The 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
