Alluvial Soils In India

Alluvial Soils In India

These soils are formed by the sediments brought by the rivers, and are rich in chemical ingredients. The rivers deposit very fine particles of soil called alluvium in their plains during the course of their long journey. Alluvial Soil is also known as riverine soil because it is mainly found in the river basins. It is a mixture of sand, clay and silt, called loam. These soils occupy 40 per cent of the land area. The entire Northern Plains are made up of these soils. They form the largest and most important group as they contribute the largest share to the agriculture wealth of India. These soils are also predominant in coastal plains and deltas.


These soils are found on the plains of the Indus, the Ganga and the Brahmaputra rivers, extending from Punjab and Sindh (Pakistan) to Bangladesh and Assam (India). Punjab, haryana, Utter Pradesh, Bihar, West Bengal have alluvial soils. These soils also cover a part of Gujarat and a few patches in Rajasthan.
