Abstract - Regur soil, commonly known as black cotton soil,
development of tailored agricultural techniques to maximize productivity. Today, regur soil continues to underpin agricultural practices in regions like the Deccan Plateau in India, with farmers employing conservation measures to sustain its fertility amidst modern challenges like erosion and nutrient depletion. Thus, the history of regur soil mirrors the evolution of agricultural practices, shaped by cultural, economic, and scientific influences, while emphasizing the importance of conservation for future generations.
is prevalent in various regions around the world, presenting unique challenges due to its expansive nature and low bearing capacity. In recent years, researchers and engineers have explored numerous methods to improve its engineering properties, with a particular focus on enhancing its strength. One such method involves the addition of high calcium lime in varying proportions to the regur soil. This review paper comprehensively examines the research conducted on this topic, summarizing the findings, methodologies, and outcomes of studies investigating the effects of high calcium lime addition on the strength characteristics of regur soil. Through a systematic analysis of the literature, this paper elucidates the mechanisms by which high calcium lime interacts with regur soil, influencing its geotechnical properties such as compressive strength, shear strength, and California Bearing Ratio (CBR). Furthermore, this review highlights the significance of optimizing the percentage of lime addition to achieve desired improvements in soil strength while considering factors such as soil type, lime content, curing conditions, and environmental considerations. By synthesizing the existing knowledge, this paper provides valuable insights for researchers, engineers, and practitioners engaged in soil stabilization projects, offering guidance for the effective utilization of high calcium lime to enhance the strength and performance of regur soil.
2.REGUR SOIL Regur soil, commonly known as black soil, is a type of soil found in the Deccan Plateau region of India. Its name is derived from the Marathi word 'regur,' which means 'to swell.' This soil is renowned for its remarkable fertility, making it highly conducive to agriculture. Characterized by its dark color and high clay content, regur soil has excellent moisture retention properties, enabling crops to thrive even during dry spells. However, its high clay content also poses challenges, such as poor drainage and susceptibility to waterlogging. Despite these drawbacks, regur soil is highly prized for its ability to support a variety of crops, including cotton, soybeans, and cereals like sorghum and millets. Proper management techniques, such as implementing drainage systems and employing suitable crop rotation practices, are essential for maximizing the productivity of regur soil and sustaining its fertility for future generations.
Key Words: Regur Soil, Strength, Lime, Improvement of Regur soil, Compressive strength, Shear Strength.
1.BACKGROUND Regur soil, colloquially known as black cotton soil or black soil, boasts a rich historical tapestry intertwined with agricultural development in tropical regions. Originating from the weathering of basaltic rocks over millions of years, its formation endowed it with rich mineral content, including iron, magnesium, calcium, and potassium. Evidence suggests that ancient civilizations such as the Indus Valley Civilization and later the Vedic peoples utilized these fertile lands for agriculture, cultivating crops like millet, pulses, and cotton. However, it was during the British colonial era in India that the true agricultural potential of regur soil came to light. British officials recognized its suitability for cash crops like cotton and promoted its cultivation, reshaping land use patterns and agricultural practices. Subsequent research delved into the unique properties of regur soil, leading to the
