Abstract
According to the morphological and physiological characteristics of vetiver roots, it can be usedas the most suitable protective wall on the steep and side slopes. For this purpose, this study was carried out on the side slopes of Sangar Dam reservoir in Siahkol city in Gilan province. In this resesrch, soil and Vetiver plant roots were sampled from the depth of 0-50 cm of soil with different degrees of slope of the first surface (30-40 degrees), the second level (40-50 degrees), the third level 60-70 degrees) and four repetitions were done. The results of the research showed that with the increase in the slope, the amount of organic carbon, silt, soil clay, root weigh, Vetiver root extract weight increases. But with the increase in slope, some soil properties such as acidity, salinity, sand, humidity and lime decreases. As a result, there is a significant correlation (p≤0.05) between the soil properties and the amount of root weight and the weight of Vetiver root extract in the slope of the study area.
