Enhancing Soil Stability with Biopolymers and Vegetation




Enhancing Soil Stability with Biopolymers and Vegetation


Soil erosion is a significant environmental challenge, and improving soil stability through sustainable methods is essential for long-term erosion control. Vegetation has been a traditional method for stabilizing soil, while recent advances highlight biopolymers as eco-friendly soil stabilizers to enhance soil shear strength and erosion control. This study investigates the combined effect of xanthan gum (XG) biopolymer at concentrations of 0.5% and 1.5% and vegetation on soil shear strength and grassroots growth. Shear strength was measured using a specially designed direct shear apparatus capable of testing under low normal stresses, simulating surface soils exposed to shallow instability and erosion forces. The results demonstrated that integrating biopolymers with vegetation significantly enhances soil stability and shear strength compared to using biopolymers alone. These findings underscore the potential of biopolymers, particularly when combined with vegetation, to provide long-term erosion control with improved effectiveness.
