Types of Soil in India – Alluvial Soil. Alluvial soils are widespread in the northern plains and river valleys. It covers about 40% of the total land area of the country. These soils are mainly derived from the debris brought down from the Himalayas. In the Peninsular region, they are found in deltas of the east coast and in the river valleys.

Alluvial soil is one of the best soils, requiring the least water due to its high porosity. The consistency of alluvial soil ranges from drift sand and rich, loamy soil to silt clays. India is one of the richest countries in the world in terms of alluvial soil, which covers more than 46% of its total land area.
Alluvium (from Latin alluvius, from alluere 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit.
Alluvial soil is primarily found around rivers, where it is carried by streams as rocks weather. Let's learn the basics of this soil type.
Alluvium consists of silt, sand, clay, and gravel and often contains a good deal of organic matter. It therefore yields very fertile soils such as those of the deltas of the Mississippi, the Nile, the Ganges and Brahmaputra, and the Huang rivers.
Alluvial deposit, Material deposited by rivers. It consists of silt, sand, clay, and gravel, as well as much organic matter. Alluvial deposits are usually most extensive in the lower part of a river’s course, forming floodplains and deltas, but they may form at any point where the river overflows.
Alluvium, the parent material of alluvial soils, is the sediment deposited by fluvial systems such as rivers and streams. Alluvium includes a wide variety of mineralogical compositions and particle-size distributions, depending on the source of geologic materials and depositional environment.
Good agricultural alluvial soils are those with medium to moderately clayey textures, medium-acid to moderately alkaline reaction (pH 5.6–7.8), good supply of organic matter, and a wide variety of minerals. Most of the alluvium of these soils is derived from large drainage basins with a great variety of rocks and soils, and a large proportion ...
Jan 1, 2014 · Alluvial soil is a general term for those soils developed on recent alluvium and derived from geologic materials such as alluvium. Soils have formed on the alluvium in hydromorphic conditions (presence of excess water) and can have periodic sedimentation in accordance with seasonal fluctuation of the groundwater table.
