Abstract :Erosion is a major problem that limits vegetative production, adversely affects the ecosystem and causes soil losses that are difficult to recover. This study was carried out with the aim of determining the erosion status and some soil properties of the soils of Suruc plain in Sanlıurfa province. Soil properties; It has been determined that the pH is slightly high, the soils are non-saline, the organic matter is medium and the soil is clayey. Expresses the change of data by the coefficient of variance insert ignore into journalissuearticles values(CV);. The lowest variability insert ignore into journalissuearticles values(CV = 2.45); in the soils of Suruç plain is the other parameters, respectively, the clay ratio insert ignore into journalissuearticles values(CV = 19.27); medium level, silt ratio insert ignore into journalissuearticles values(CV = 20.64); medium level, organic matter insert ignore into journalissuearticles values(CV = 27.14); medium level and sand ratio. insert ignore into journalissuearticles values(CV = 27.34); varies moderately. It was determined that the soil properties showing the highest variability were lime insert ignore into journalissuearticles values(CV = 37.06);, EC insert ignore into journalissuearticles values(CV = 38.89); hydraulic conductivity insert ignore into journalissuearticles values(CV = 695.41);. According to the correlation coefficient of soil erosion insert ignore into journalissuearticles values(USLE-K); parameter insert ignore into journalissuearticles values(r=0.99**); and P <0.01 level, it was determined that there is a very important relationship. The high coefficient of variation of some soil properties revealed the need for more sampling in the area. According to the frequency table, the erosive degrees of the soils are determined to be 10% very little, 26% less, 56% medium and 8% strongly erodable soils. In the Suruc plain, which will be opened to irrigation within the scope of the Southeastern Anatolia project, instead of traditional irrigation methods, more suitable irrigation systems should be chosen according to the soil characteristics and the slope of the land.
