A research on harnessing MICP for soil erosion control: A sustainable approach for thar desert’s soil
Year: 2025
Type: article
Abstract: Soil erosion is a critical environmental issue, particularly in arid regions like the Thar Desert, where wind erosion accelerates land degradation. This study explores the application of Microbially Induced Calcium Carbonate Precipitation (MICP) as an eco-friendly solution for enhancing soil stability and mitigating erosion. Laboratory experiments were conducted using Sporosarcina pasteurii to induce calcium carbonate precipitation in sandy soil. The research assessed changes in soil properties, permeability, and erosion resistance through physicochemical analysis, wind tunnel testing, and unconfined compressive strength (UCS) measurements. The results demonstrated a significant reduction in porosity (18%), permeability (80%), and wind erosion mass loss (73%), alongside a 360% increase in UCS. Microscopic analysis confirmed the formation of a calcite crust, enhancing soil cohesion. This study highlights MICP’s potential as a sustainable erosion control strategy, offering a viable alternative to conventional soil stabilization methods.
