Which soil is also called Regur soil ?

The correct answer is Black soil.

Key Points

• Black soil, also known as Regur soil, is a type of soil found in areas of lava spread, especially in Deccan Plateau regions such as Maharashtra, Madhya Pradesh, Gujarat, and Andhra Pradesh.
• This soil is ideal for growing cotton, which is why it is also called "Black Cotton Soil."
• The soil is rich in calcium carbonate, magnesium, potash, and lime, but it has poor nitrogen and phosphorus content.
• It has a high capacity to retain moisture, making it suitable for dry farming.
• Black soil develops cracks during the dry season, which helps in aeration of the soil.

Additional Information

• Formation: Black soil is formed from the weathering of volcanic rocks, particularly basalt, which is why it is prevalent in the Deccan Plateau.
• Texture: It has a clayey texture, which contributes to its moisture-retaining capacity but also makes it prone to waterlogging.
• Color: The soil's black color is due to the presence of titanium oxide and iron compounds.
• Regions: Apart from India, black soils are also found in similar climatic zones globally, such as the Pampas in Argentina and certain regions in the USA.
• Challenges: Despite its fertility, black soil requires proper irrigation and fertilization management due to its susceptibility to cracks and nutrient deficiencies.
