Özet: In terms of the sustainability of ecosystems, problems associated with soil and water resources appear to be an important environmental threat. In addition to reducing soil fertility, soil erosion can cause soil nutrient losses and hence contamination of water resources by runoff. Various soil protection practices are carried out all over the world to prevent soil erosion. One of these applications is to cover soil surface with mulch. The aim of this study is to determine the effects of different mulch materials and dose applications on nitrate and ammonium transport under simulated rainfall conditions in the laboratory conditions. For this purpose, three mulch rates (2, 4, 6 t/ha) and three mulch types (straw, dry weed and peanut hay) were studied and compared to un-mulched plots.The rainfall intensity was 97 mm/h. The surface runoff formed during the application was collected and and analyzed for nitrate and ammonium losses. As a result of the study, it was found that straw and peanut hay mulching decreased ammonium transportation and peanut hay mulching decreased the nitrate transportation. In addition 6 t / ha mulch application was found to reduce ammonium transportation.
