BLACK SOIL + SOIL EROSION

What are black soils also known as?

Black soils are also known as regur soils.

What type of crops are black soils ideal for?

Black soils are ideal for growing cotton and are also known as black cotton soil.

What are the main factors for the formation of black soil?

The climatic condition and the parent rock material are the important factors for the formation of black soil.

Where is black soil typically found?

Black soil is typical of the Deccan trap (Basalt) region in northwest Deccan plateau, covering areas such as Maharashtra, Saurashtra, Malwa, Madhya Pradesh, and Chhattisgarh.

What is the texture of black soil?

Black soil is made up of extremely fine, clayey material.

What is a notable characteristic of black soil regarding moisture?

Black soils have a well-known capacity to hold moisture.

Which soil nutrients are black soils rich in?

Black soils are rich in calcium carbonate, magnesium, potash, and lime.

What nutrient are black soils generally poor in?

Black soils are generally poor in phosphoric contents.

What happens to black soil during hot weather?

Black soils develop deep cracks during hot weather, aiding in proper aeration.

How does black soil behave when wet?

They are sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.

What is soil erosion?

Soil erosion is the denudation of the soil cover and subsequent washing down.

What leads to soil erosion?

Soil erosion can be caused by both human activities, like deforestation and over-grazing, and natural forces, such as wind, glaciers, and water.

What happens to clayey soils during erosion?

Running water cuts through clayey soils, creating deep channels known as gullies.

What is considered bad land?

Land that becomes unfit for cultivation due to erosion is known as bad land.

What are ravines in the Chambal basin?

In the Chambal basin, land made unfit for cultivation due to erosion is specifically referred to as ravines.

What is sheet erosion?

Sheet erosion occurs when water flows as a sheet over large areas down a slope, washing away topsoil.

What causes wind erosion?

Wind erosion occurs when loose soil is blown off flat or sloping land by the wind.

How can defective farming methods contribute to erosion?

Defective farming methods, such as ploughing up and down slopes, can form channels that accelerate water flow and lead to soil erosion.

What is contour ploughing?

Contour ploughing is the practice of ploughing along contour lines to decelerate water flow down slopes, thus reducing erosion.

What is terrace cultivation?

Terrace cultivation involves cutting steps on slopes to restrict erosion, commonly found in the western and central Himalayas.

What is strip cropping?

Strip cropping is the method of dividing large fields into strips with grass between crops to disrupt wind force and reduce erosion.

What are shelter belts?

Shelter belts are rows of trees planted to create shelter, aiding in stabilising sand dunes and deserts, particularly in western India.
