Abstract - Black cotton soil, also known as Regur soil, is
a growing recognition of sustainable agricultural methods and the necessity to enhance soil quality without excessive reliance on chemical supplements. Researchers and agronomists have long been engaged in seeking alternative approaches to enrich soil properties and crop productivity while minimizing environmental repercussions. Initially, laboratory experiments likely focused on unraveling the biochemical processes involved in soil stabilization and nutrient cycling. Various bio-enzymes such as cellulases, proteases, and amylases would have been scrutinized for their effects on soil structure and fertility, laying the foundation for subsequent field trials to evaluate practical applications in real-world agricultural scenarios. As the body of research expanded, scientists would have refined methodologies and gained deeper insights into the intricate mechanisms by which bio-enzymes interact with regur soils. Factors including enzyme dosage, application techniques, and environmental considerations would have been meticulously evaluated to optimize the efficacy of bioenzyme treatments. Collaboration among soil scientists, microbiologists, agronomists, and agricultural engineers would have been instrumental, fostering a multidisciplinary approach to research. Field trials conducted across regur soil regions on farms and research stations would have assessed the scalability and feasibility of bio-enzyme treatments for farmers. As research progressed, dissemination of findings through scientific publications, conferences, and extension programs would have served to enlighten farmers and policymakers about the potential advantages of employing bio-enzymes to enhance soil quality and crop yields in regur soil areas.
widespread across various regions globally, posing challenges due to its expansive nature and low shear strength. Recently, bio-enzymes have emerged as a promising solution to address the adverse effects of Regur soil on construction projects. This paper aims to comprehensively review existing literature on the efficacy of bio-enzymes in bolstering the strength of Regur soil. The review begins by outlining the physicochemical properties of Regur soil and the impediments it presents to construction endeavors. It then delves into the mechanisms through which bio-enzymes interact with Regur soil, encompassing soil stabilization, structural enhancement, and improvement of shear strength. Various application methodologies of bio-enzymes are explored, alongside an assessment of their efficacy under different conditions. Factors such as soil composition, enzyme type, dosage, and environmental variables influencing the efficiency of bioenzymes are also scrutinized. The paper examines case studies and experimental findings from pertinent research to offer insights into the practical implications of utilizing bio-enzymes for Regur soil stabilization. Ultimately, it concludes with recommendations for future research directions and practical considerations for integrating bio-enzymes into engineering applications. Overall, this review contributes to advancing understanding regarding the potential of bio-enzymes in fortifying Regur soil strength and facilitates informed decision-making in geotechnical engineering and construction practices. Key Words: Regur soil, black cotton soil, bio-enzymes, soil strength enhancement, soil stabilization, shear strength, geotechnical engineering.
The historical journey of studying the impact of bio-enzymes on augmenting regur soil strength embodies a pursuit of scientific exploration and innovation, aimed at devising sustainable solutions to confront the challenges of modern agriculture while safeguarding soil and environmental health.
1.BACKGROUND Exploring the influence of bio-enzymes on enhancing the strength of regur soil marks a significant advancement in soil engineering and agricultural practices. This research seeks to decipher how biological catalysts, known as bio-enzymes, can affect both the mechanical attributes and fertility levels of regur soils. Regur soils, alternatively referred to as black soils or black cotton soils, are distinguished by their high clay content and expansive behavior. Predominantly found in the Deccan Plateau region of India, these soils are renowned for their fertility, yet they are prone to cracking and shrinking during dry periods. The exploration of bioenzymes' impact on regur soil strength can be traced back to
