Answer 1

Answer:

Alluvial soil is the most fertile and widespread soil found in India. It is formed due to the deposition of fine silt called alluvium by the rivers. It consists of sand, silt and clay. It contains soil nutrients such as Potash, phosphoric and lime. It is divided into Khadar and Bangar (new alluvium and old alluvium). It is fertile and good for the growth of sugarcane, rice, wheat and pulses

Answer 2

• Alluvial soil is soil deposited by surface water.
• It can be found in rivers, plains and deltas (such as the Mississippi Delta), on river terraces, and in areas called alluvial fans.
• The last category is the result of a triangular fan-shaped distribution of soil due to flooding.
• The alluvial plains are found in the valleys of the Terrain region and the Jonathan valleys around Kathmandu and Pokhara.
• This valley lies between the Sivalik and Mahabharat mountains, and in some places passes into a flat, fertile valley called the Dan Valley.
• A new alluvial soil has been deposited in the floodplain, containing more sand and silt than clay.
• Alluvial soil is also found in the uplands above the floodplain, which covers much of the Terrain.
• The nutrient content of new alluvial soil is medium to moderate depending on till age time. On the other hand, the nutrient content of the old alluvial soil is very low.
• The most fertile soil is alluvial soil.
• Alluvial soils are deposited by rivers. It is usually formed by mixing salts and other minerals with fine particles of various soils and contains animal and vegetable matter in a completely decomposed state.
• Contains moderate amounts of phosphoric acid, potassium salts .
