Characteristic features of Badland are the lack of vegetation, steep slopes and dense drainage network are considered as important sources of erosion and sediment production in the world. The extent to which different physical and chemical factors of the soil in the formation and spread of pustular erosion varies from point to point. The aim of this study was to identify the most important factors of physical and chemical properties of soil and environmental factors and soil depth in the spread of Badland erosion in the Zanuzchay watershed of East Azerbaijan province. In this study, factors such as the percentage of sand, silt and clay, PH, EC, SAR, organic matter, gypsum and soil lime in different altitude classes and in the east-west direction and in three depths of 5-0, 30-5 and -60 30 Badland erosion facies were examined. The results of mean comparison using non-paired t-test and Levin test show a significant difference between the variables of pH, SAR, gypsum, clay percentage, silt percentage and organic matter of Badland lands and control lands at the level of one percent. Comparison of average sand in different classes and directions and in depths (0-5) and (5-30) and less than 30 cm in Badland and control areas with Duncan test shows the difference in level five Is a percentage. The results also showed that the average percentage of clay and sand at different heights have a significant difference at the level of five percent.
