Black soil is also known as regur soil or black cotton soil.
Explanation:
Black cotton soil, also known as regur soil, is a type of soil found in the Deccan Plateau in India. This soil type is known for its unique properties, such as its deep black colour, high fertility, and ability to retain moisture.
Regur soil is formed from the weathering of basalt rocks, which are rich in minerals like iron, magnesium, calcium, and potassium. The high mineral content in the soil makes it extremely fertile and ideal for agriculture.
Additionally, the soil’s ability to retain moisture helps crops grow even in arid regions where rainfall is scarce.
However, the unique properties of black cotton soil also make it challenging for construction projects. When dry, the soil shrinks and cracks, which can cause buildings and other structures to settle unevenly. When wet, the soil becomes extremely soft and can cause buildings to sink.
To work around these challenges, builders often use specialized techniques to stabilize the soil, such as using deep foundation systems or adding lime to the soil to increase its strength and stability.
Overall, black cotton soil is a valuable natural resource in India, providing fertile land for agriculture and supporting the country’s growing economy.
