What regions are rich in alluvial soil?

What regions are rich in alluvial soil?

Most alluvial soils are derived from the sediment being deposited by the river Ganga in the Indo–Gangetic plain, ranging from Punjab in the west to West Bengal and Assam in the east, as well as in the coastal areas of northern parts of Gujarat, Narmada, and Tapi valleys, which are formed by sea waves.

In which region alluvial soil is found?

Alluvial soil is found in the regions of Indo-Gangetic plains, Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal, Assam as well as in the northern parts of Gujarat. Alluvial soil is formed by depositions from surface water and thus is also known as depositional soils.

What is the region of the old alluvial soil called?

Bhangar
Old Alluvial soil is called Bhangar. In the Upper and Middle Ganga plain, two different types of alluvial soils have developed, viz. Bhangar and Khadar .

Which nutrients are rich in alluvial soil?

The alluvial soils vary in nature from sandy loam to clay. They are generally rich in potash but poor in phosphorus.

What is the two types of alluvial soil?

Alluvial soil can be classified into two groups on the basis of its age – the khaddar and the bhangar. The former is light in colour and is made up of newer deposits. The latter is the older alluvium and is composed of lime nodules or kanker and its composition is clayey.

Which crop is best for alluvial soil?

Alluvial soils are best suited to the irrigation system and respond well to canal and well or tube-well irrigation. They yield splendid crops of rice, wheat, sugarcane, tobacco, cotton, pulses, oilseeds, jute, maize, oilseeds, leguminous crops, vegetables, and fruits, etc.

What is the other name of alluvial soil?

Alluvium is also sometimes called alluvial deposit.

Which soil is known as black cotton soil?

regur soil
Black soil is also known as black cotton soil or the regur soil. Black cotton soil is known as ‘tropical chernozems’ in the other parts of the world. These soils are named as black cotton soil as it is famous for the purpose of cultivation of cotton.

What is the two types of Alluvial soil?

Which deficiency is found in Alluvial soil?

Alluvial soils (Fluvisols) These soils are deficient in nitrogen (N), phosphorus and organic matter. Generally, alluvial soils range from near neutral to slightly alkaline in reaction. A wide variety of crops is grown in these soils.

What is the classification of alluvial soil?

According to their age alluvial soils can be classified as old alluvial (Bangar) and new alluvial (Khadar). The bangar soil has higher concentration of kanker nodules than the Khadar. It has more fine particles and is more fertile than the bangar. Alluvial soils as a whole are very fertile.

What is the pH of alluvial soil?

Texture and colour: layered alluvial loams The pH is 7.5 to 8.0.

Where are sandy alluvial soils found in India?

In Punjab State, India, sandy alluvial soils, although they may be low in extractable S, generally do not respond to applied S because irrigation waters from groundwater sources contain considerable SO4.

Where is the best place to plant alluvial soil?

New alluvial soil with more sand and silt than clay is being deposited in the flood plain areas along the river courses. Alluvial soil is also found in the higher areas above the flood plain covering a greater part of the Terai. The nutrient content of new alluvial soil is fair to medium depending on how long it has been cultivated.

What are the constituents of an alluvial soil?

Depending on the mineralogical composition and texture of the parent material, B horizons develop in the subsoil and accumulate constituents such as silicate clay, free iron oxides, and metal humus complexes. In subhumid, semiarid, and arid climates, alluvial soils are incompletely leached.

How are alluvial deposits and landforms subject to erosion?

Alluvial deposits, landforms, and the associated soils can be subject to active fluvial processes at one time or another. Therefore all or a portion of an alluvial soil profile is subject to erosion. If only a portion of the soil is removed by erosion, the soil has been truncated.
