After laying a permeable clothe on thecoarse gravel layer, soil samples which were thought to the 8 mm sieve, were placedinto the erosion pan. Liquated humic substance, PAM and PVA solutions (0, 1, 2 and4 ml l-1; 100 ml) were sprayed uniformly on soil surface by a hand type pump with 2replicated. 40 mm h-1 of artificial rainfall was applied during 1 hour by a laboratory typerainfall simulator. The runoff start time is measured with a stopwatch. Runoff and soillosses were calculated and tabulated.Results: In this study, liquated humic substance, PAM and PVA treatments decreasedrunoff and soil loss significant levels.Conclusions: Runoff and soil loss were decreased by using these solutions Therefore,liquated humic substance, PAM and PVA solutions can be use reducing the erosioneasilyen10.20289/zfdergi.580533info:eu-repo/semantics/openAccessComparing of the Effects of Liquated Humic Substance (LHS), Polyacrylamide (PAM) and Polyvinylalcohol (PVA) on Runoff and Soil LossesArticle573351358415919
