Abstract
The most of the soil erosion and sediment yield in the Talkheh Rood watershed are mainly related to marl formations. This study was conducted to evaluate physico- chemical properties of Talkheh Rood marl samples in rill, gully, mass and badland erosion types. For this purpose, marl samples were taken from marl sediment of homogenous work units. Twenty four samples were selected, in total. Some of main physic - chemical properties of these marls were measured in lab. These properties were pH, EC, CEC, Lime, gypsum and OC content, SAR, Na, K, Cl, Ca, Mg, clay, silt and sand percentage. These data were interpreted by ANOVA and mean comparisons analysis methods. Results showed that pH, gypsum content and sand percentage had statistically significant differences between four erosion types. Mean comparison showed that significant difference of pH, was between mass and badland erosions, sand between badland and gully ones, and gypsum, rill and gully, also badland and gully ones.
