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 laboratorytype rain simulator.Material and Methods: In this study, the 7 cm coarse gravel was placed into the erosionpan, which sized 30x45x15 cm, sloped of 9 %. 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 erosioneasily
