Abstract

Splash erosion recognized as first stage of erosion process that results of bombing soil surface with rain drop. Falling rain drops to soil surface resulted moving soil particles and destructing soil structure. At this research effects of various PAM rate (0, 2, 4 and 6 kg.ha) on splash erosion on three soil textuere clay, silty clay and sandy clay loam was tested. Simulations were done with rain intensity of 95 mm/h using a FEL3 rainfall simulator in laboratory. Splash erosion rate were measured using splash cup. Results showed that there is no statistically difference between different soil textures in order to decreasing splash rates. Effect of different applying PAM in splash erosion rate showed that there is significantly differences between control treatment with 4 and 6 Kg/ha treatment in 95% level (Fvalue=4.5, Pvalue= 0.039) in sandy clay loam soil texture. Also the results showed splash erosion rates have decreased by 42.3 and 52 percent comparing to control treatment when applied 4 and 6 Kg/ha treatments. Our findings can be useful for better management of agricultural soils in order to sustainable yield and soil sonservation.
