What is black soil?

Question

What is black soil?

Answer

Black soil is formed due to the solidification of larva spread over areas during volcanic activity in Deccan plateau, thousands of years ago. This soil are also called Regur soils....

Answer

Black Soil: Definition and Characteristics

Black soil, also known as black cotton soil or regur soil, is a type of soil that is found in the Deccan Plateau of India, as well as other parts of the world, such as Texas in the United States. It is characterized by its dark color, high fertility, and ability to retain moisture.

Formation

Black soil is formed from volcanic rock and ash, which have been weathered and broken down over time. The soil is rich in minerals, such as calcium, magnesium, potassium, and iron, which make it very fertile.

Characteristics

Color: Black soil is dark in color, which is due to its high organic matter content. The soil contains a high amount of humus, which is the decomposed plant and animal matter that gives the soil its dark color.

Texture: Black soil has a fine texture, which makes it easy to cultivate. The soil is also very sticky when wet, which can make it difficult to work with.

Fertility: Black soil is highly fertile due to its mineral content. The soil has a high amount of calcium, magnesium, potassium, and iron, which are essential nutrients for plant growth.

Water retention: Black soil has the ability to retain moisture, which makes it ideal for crops that require a lot of water, such as cotton and sugarcane. The soil can hold up to 40% of its weight in water.

Drainage: Black soil has poor drainage, which can lead to waterlogging and soil erosion. However, this can be improved by adding organic matter to the soil.

Uses

Black soil is used for a variety of purposes, including:

Agriculture: Black soil is ideal for growing crops such as cotton, sugarcane, and soybeans, which require a lot of water and nutrients.

Construction: Black soil is also used in construction, as it has good load-bearing capacity and can be compacted easily.

Landscaping: Black soil is used in landscaping to improve soil quality and promote plant growth.

In conclusion, black soil is a highly fertile soil that is characterized by its dark color, high organic matter content, and ability to retain moisture. It is widely used in agriculture, construction, and landscaping, and is an important natural resource in many parts of the world.

Answer

Black soils, also called regur or black-cotton soil, are spread mostly across the Deccan Lava Plateau, the Malwa Plateau, and interior Gujarat, where there is both moderate rainfall and underlying basaltic rock. Because of their high clay content, black soils develop wide cracks during the dry season, but their iron-rich granular structure makes them resistant to wind and water erosion. They are also highly moisture-retentive, thus responding well to irrigation.

Answer

Black soil is also known as regur soil and perfect for the growth of cotton....it is second largest wide spread soil in India....the clay contact in the soil is very high and it has high fertility.......it is dark in colour.....and found in between 50degree north and 45degree south.
