Özet
Objective: The aim of this study is to determine the effects of liquated humic substance, polyacrylamide and polyvinylalcohol on runoff and soil losses by using a laboratory type rain simulator. Material and Methods: In this study, the 7 cm coarse gravel was placement into the erosion pan, which sized 30x45x15 cm, sloped of 9 %. After laying a permeable clothe on the coarse gravel layer, soil samples which were thought to the 8 mm sieve, were placement into the erosion pan. Liquated h umic substance, PAM and PVA solutions (0, 1, 2 and 4 ml l -1 ; 100 ml) were sprayed uniformly on soil surface by a hand type pump with 2 replicated. 40 mm h -1 of artificial rainfall was applied during 1 hour by a laboratory type rainfall simulator. The runoff start time is measured with a stopwatch. Runoff and soil losses were calculated and tabulated. Results: In this study , liquated humic substance, PAM and PVA treatments decreased runoff and soil loss significant levels. Conclusions: Runoff and soil loss were decreased by using these soulutions Therefore, liquated humic substance, PAM and PVA solusions can be use reducing the erosion easily.
