Abstract - Expansive soil exhibits a remarkable capacity for absorbing substantial quantities of water, resulting in significant volume fluctuations that lead to seasonal expansion and contraction based on water availability. This phenomenon can result in structural damage and failure for any buildings constructed on such soil. Various strategies have been implemented to tackle the swelling problem associated with this type of soil, including preloading for moisture control, replacing affected soil, and incorporating additives such as lime, cement, fly ash, or other industrial by-products. Numerous research endeavors have explored the modification of expansive soil behavior through these additives. The primary aim of the present study is to ascertain the most effective application of lime as a soil modifier when necessary. To accomplish this objective, we introduced varying proportions (3%, 4%, 5%, and 6%) of lime to black cotton soil prior to conducting geotechnical tests to evaluate its impact on properties such as plasticity, compaction, consolidation, swelling potential, and strength. Our investigation revealed that higher lime concentrations significantly influenced specific properties, such as plasticity and strength, in comparison to lower levels. In our research paper on the impact of lime treatment on geotechnical parameters' strength measurements in black cotton soil, we conducted liquid limit tests, plastic limit assessments, and examined factors like plasticity index values through compaction tests, as well as California Bearing Ratio assessments.

like waterlogging and crop fatalities. Over time, farmers have devised an array of methodologies to alleviate these obstacles, encompassing contour farming, bunding, and the employment of deep plowing. Despite its intricacies, ebonyhued cotton soil endures as an indispensable facet of India's agricultural legacy, epitomizing the perseverance and resourcefulness of its agriculturalists in harnessing the land's potential for sustenance and prosperity.
2.REGUR SOIL Ebony hued cotton soil, also referred to as regur soil, stands as a distinctive element within India's agricultural terrain. Its profound black hue and elevated clay composition present both a blessing and a hurdle for agricultural practitioners. Predominantly located in the Deccan Plateau, notably in regions like Maharashtra, Gujarat, and Karnataka, this soil variant boasts a storied past intricately woven into the agricultural evolution of the area. Renowned for its fertility, it sustains a diverse array of crops, encompassing cotton, sorghum, and pulses. Nevertheless, its pronounced expansiveness during the monsoon season may give rise to challenges such as waterlogging and crop failures, thereby posing formidable obstacles for farmers. Throughout the years, farmers have devised innovative strategies to navigate these obstacles, exemplified by practices like deep plowing and contour farming. Despite its intricate nature, black cotton soil stands as a pivotal component of India's agricultural legacy, epitomizing the resilience and ingenuity of its farming communities in harnessing the land's potential for nourishment and advancement.
1.BACKGROUND Ebony-hued cotton soil, commonly referred to as regur soil, holds a prominent position in the agricultural annals of India. Spanning vast expanses of the Deccan Plateau, notably in regions such as Maharashtra, Gujarat, Karnataka, and sections of Madhya Pradesh, this soil variant has been instrumental in sculpting the agricultural topography of the subcontinent. The historical lineage of ebony-hued cotton soil in India traces back numerous centuries, wherein its distinctive attributes have both conferred advantages and posed challenges to farmers. Its inky hue and elevated clay composition render it exceptionally fecund, capable of nurturing a variety of crops such as cotton, sorghum, millets, and pulses. Nonetheless, its pronounced expansiveness during rainy seasons presents hurdles, giving rise to issues
