Integration of Plants and Microbially Induced Soil Stabilization for Sustainable Infrastructure Design
Integration of Plants and Microbially Induced Soil Stabilization for Sustainable Infrastructure Design
Over the past two decades, bio-mediated soil stabilization methods like microbially induced carbonate precipitation (MICP) have gained popularity. With a well-established understanding of the mechanical properties of MICP-cemented soil, researchers aim to mitigate the environmental impacts associated with this method, driving the technology toward practical field implementation. The surface layer of soil serves as an important zone supporting numerous plant and microbe communities. Healthy vegetation can support infrastructure needs (e.g., erosion resistance) as well as provide habitat for wildlife. Nevertheless, the influence of MICP on plants and how these alterations may affect the mechanical properties of soil is currently unknown. The presented study introduces and investigates the role of factors such as plant species, and treatment solution concentrations on the compatibility of MICP and vegetation. The results of this study can be used to integrate plants in the design of MICP-treated soil to ensure nature-based engineering solutions.
