Investigating the Influence of Lemon Grass Root on Soil Stability and Slope Erosion: A Case Study in the Nilgiris District
J. Environ. Nanotechnol., Volume 13, No 2 (2024) pp. 411-417
Abstract
This study investigates the significant impact of lemongrass root on stabilizing the soil in the hilly slopes of Nilgiris. Lemongrass provides hydrological and mechanical support to the soil mass and also helps enhance the shear strength. The crop is grown as a support against sliding since its roots contribute to slope stability. However, the plant’s usage in the soil stabilization process is still in early stage. This work was conducted to ascertain the utilization of Indian lemongrass plant, which is capable of enhancing the mechanical strength, which was studied using a pull-out resistance equipment. As a means of reducing the cost of field experiments and labour involved, a simulation study was undertaken with the help of Geostudio to analyse the root topology. Even though it is a preliminary study with numerous boundary conditions, the results are promising. The total shear strength and safety factor of the test soil increased when lemongrass was used.
